Cycle on Jun 7, 2026

I will list the current open threads and watches for this topic to see what has been prioritized or monitored in past cycles.

I will read the existing notes for this topic to understand what work has already been done on the market map, OpenAI Deep Research, Perplexity, and other tools, and to see where we can add more specific value.

I see that we have several prior findings covering: - `market-map-positioning-hey-lefty` - `academic-ai-research-scholar-vs-synthesis` - `perplexity-deep-research-consumer-agent` - `gemini-deep-research-agent` - `sacra-premium-private-market-mcp-data` - `openai-deep-research-api-and-pro-tier` - `integrating-custom-mcp-servers` Let's do some web searches to see what the latest state of the market is, especially focusing on: 1. "Gemini Deep Research" (features, price, API, availability, custom integrations) 2. "Sacra" (pricing model, value prop, how they sell, what they do) 3. "Perplexity Deep Research" (features, pricing, API, how it compares) 4. "OpenAI Deep Research" (pricing, features, API) 5. Google Scholar vs AI tools (Consensus, Elicit, etc.) 6. How Hey, Lefty fits in, particularly if there are new developments in these platforms. Let's do a web search on Sacra's business model, pricing, and how it delivers its data (e.g., API, MCP, web subscription) to make sure our understanding of Sacra is fully updated and grounded in recent 2026 data. Let's also search for any recent discussions or launches on Gemini Deep Research or OpenAI Deep Research. First, let's search for "Sacra" research platform, business model, pricing, and features.

Let's fetch Sacra's pricing page and their docs or API intro to get the solid, concrete details on their plans, features, and model. This will let us refine the Sacra note with high-fidelity 2026 data.

Let's also check Sacra's API docs to see how their API works, what kind of endpoints they have, and how they describe their data model. Let's do a search on `docs.sacra.com` or fetch some API details.

Wow, Sacra is doing some very interesting things, including "Model Context Protocol (MCP) server access" on all levels (Standard, Pro, Platform, Enterprise). Let's fetch `https://docs.sacra.com/` and `https://docs.sacra.com/mcp-anywhere` to understand their API and MCP server integration fully. This is highly relevant to `integrating-custom-mcp-servers` and `sacra-premium-private-market-mcp-data`. Let's fetch both!

Let's fetch `https://docs.sacra.com/mcp-anywhere` to see what tools their MCP server exposes and how it works. This is premium research!

This is incredibly rich context! Sacra is positioning itself heavily around MCP (Model Context Protocol). They have a dedicated MCP server running over HTTP (`https://mcp.sacra.com/mcp`) that exposes tools like `get_company_profile`, `get_funding_rounds_for_company`, and `get_news_for_company`. Let's fetch `https://docs.sacra.com/llms.txt` to see what else they expose and how they describe their endpoints. This is a brilliant way to get detailed, exact details. Let's do a fetch of `https://docs.sacra.com/llms.txt`.

This is an incredibly detailed mapping of Sacra's API and MCP capabilities. Now let's do some web searches regarding Gemini Deep Research, OpenAI Deep Research, and Perplexity Deep Research to see what pricing and features look like in 2026. Let's search for "Gemini Deep Research pricing", "Gemini Deep Research API", "OpenAI Deep Research pricing API", "Perplexity Deep Research API pricing".

Let's fetch `https://ai.google.dev/gemini-api/docs/interactions/deep-research` to get the actual API documentation, features, and pricing details for Gemini Deep Research. This is incredibly high-value primary research.

This is fantastic! Let's check `https://blog.google/innovation-and-ai/models-and-research/gemini-models/next-generation-gemini-deep-research/` to find more about "Deep Research Max" and Google's recent announcement (which seems to have happened in 2026, as the blog post says "Deep Research and Deep Research Max are available starting today in public preview via paid tiers in the Gemini API"). Let's search for "Deep Research Max" to see if we can find the blog post content.

Let's fetch `https://blog.google/innovation-and-ai/models-and-research/gemini-models/next-generation-gemini-deep-research/` to get the actual text of Google's announcement of Deep Research and Deep Research Max! This is extremely helpful to understand their core value prop, architecture, benchmarks, and target audience.

This is an absolute goldmine. Google's Gemini Deep Research has evolved significantly. Let's see: 1. They released **Deep Research** and **Deep Research Max** in public preview in **April 2026** (built with **Gemini 3.1 Pro**). 2. It's accessible via the **Interactions API**. 3. It natively supports **MCP (Model Context Protocol)**, allowing developers to connect custom remote MCP servers (e.g., Sacra, FactSet, S&P Global, PitchBook) securely to the research agent. This transforms it from a simple web searcher into an autonomous agent capable of navigating specialized databases. 4. It features **Collaborative Planning** where users can review and modify the research plan before execution. 5. It features **Native Visualizations (charts and infographics)** in HTML or "Nano Banana" formats. 6. It supports **Multimodal Grounding** (PDFs, CSVs, images, audio, video as input). 7. It supports **Real-time Streaming** of intermediate reasoning/thought summaries. Let's search for "OpenAI Deep Research API pricing 2026" and see what OpenAI has done in response. Let's do a search.

Let's fetch `https://openai.com/index/introducing-deep-research/` to read OpenAI's official announcement of Deep Research and its features. This will give us the exact timeline, features, and target audience.

Let's search for "Consensus AI" and "Elicit AI" to see how specialized academic research synthesis tools compare, or what their features, pricing, and business models are in 2026. Let's do a search.

Let's fetch `https://papersflow.ai/blog/elicit-vs-consensus-ai` and `https://bioskepsis.ai/blog/elicit-vs-consensus/` to get concrete 2026 data comparing Elicit and Consensus. This will make our findings on academic synthesis highly detailed and grounded.

This is a beautiful comparison of Elicit vs Consensus in 2026. Let's analyze the current findings we have: 1. `market-map-positioning-hey-lefty` 2. `academic-ai-research-scholar-vs-synthesis` 3. `perplexity-deep-research-consumer-agent` 4. `gemini-deep-research-agent` 5. `sacra-premium-private-market-mcp-data` 6. `openai-deep-research-api-and-pro-tier` 7. `integrating-custom-mcp-servers` Wait, let's see what else we can search for. Let's look up how Perplexity Deep Research has evolved. Let's do a search for "Perplexity Deep Research pricing API features 2026".

Let's fetch `https://docs.perplexity.ai/docs/getting-started/pricing` and `https://www.perplexity.ai/changelog/what-we-shipped---february-6th-2026` to see what Perplexity has shipped for Deep Research and Sonar. This will give us awesome, super-up-to-date 2026 data.

This is an incredibly detailed and precise breakdown of how Perplexity's API pricing works in 2026! Look at the pricing structure: - **Sonar Deep Research** input tokens: $2/1M, output tokens: $8/1M, citation tokens: $2/1M, search queries: $5/1K ($0.005 each), reasoning tokens: $3/1M. - They have a detailed cost example where a Deep Research query with 33 input, 7163 output, 20016 citation, and 73997 reasoning tokens + 18 search queries costs **$0.409** (very cheap compared to OpenAI's deep research which can cost up to $30 per call, or Gemini Deep Research which is also pay-as-you-go but uses Gemini 3.1 Pro). - They also offer an **Agent API** that provides access to third-party models (from OpenAI, Anthropic, Google, and xAI) at direct provider rates with no markup, but charges for tools like `web_search` ($0.005/invocation), `fetch_url` ($0.0005/invocation), `people_search` ($0.005/invocation), `finance_search` ($0.005/invocation), and `sandbox` ($0.03/session). Let's fetch `https://www.perplexity.ai/changelog/what-we-shipped---february-6th-2026` to see what they shipped for Deep Research. This is incredibly useful.

This is incredible. Perplexity has upgraded Deep Research to use **Opus 4.5** for Max and Pro users (as of Feb 2026), and they've introduced **Model Council** which runs three frontier models in parallel, compares outputs, and has a separate model review and synthesize them. They've also upgraded the Comet Browser Agent to use **Opus 4.6** (in Feb 2026). Wait, let's look at the pricing tiers for Perplexity: - **Pro**: $20/month. - **Max**: Let's find out what Perplexity Max is! It's mentioned multiple times ("Opus 4.5 for Max and Pro users", "Model Council is available now on web only for Perplexity Max subscribers", "Max subscribers can now choose the model powering their browser agent..."). Let's do a search for "Perplexity Max pricing features" to see what the Max tier is. This is a crucial distinction from the Pro tier!

This is extremely clear and interesting! Perplexity has introduced a **Max** tier in 2026 for **$200/month** (or $2,000/year). Let's see: - **Pro**: $20/month. - **Max**: $200/month. It includes "Model Council", exclusive "Comet browser access" (running Opus 4.6), "Perplexity Computer" (10,000 monthly credits + 35,000 bonus credits for automating tasks), and more advanced reasoning models like Opus 4.5. - There's also **Enterprise Pro** ($40/month per seat) and **Enterprise Max** ($325/month per seat or $3,250/year). Let's do a search on `https://www.perplexity.ai/max` or `https://www.perplexity.ai/pro` to get the official feature list of Perplexity Max. This is excellent! Let's fetch `https://www.perplexity.ai/max` if we can, or search for its details.

This is excellent. Let's see what we have gathered so far on the market landscape: - **Sacra**: Positioning itself as "agent-ready infrastructure" for private market research. They have a dedicated Model Context Protocol (MCP) server running over HTTP (`https://mcp.sacra.com/mcp`). They charge $50/mo (Standard), $350/mo (Pro), $1500/mo (Platform), and Custom (Enterprise). They offer company and market reports, charts & datasets, expert interviews, filings, revenue/valuation models, and API/MCP server access on all paid plans. - **Gemini Deep Research**: Built with Gemini 3.1 Pro, available in public preview (as of April 2026) via paid tiers in the Gemini API using the **Interactions API**. It comes in two versions: **Deep Research** (optimized for speed/efficiency) and **Deep Research Max** (comprehensive, extended test-time compute, asynchronous). Features include: collaborative planning (user reviews/modifies the plan before execution), native visualizations (charts/infographics in HTML or Nano Banana format), multimodal grounding, and remote MCP support (allowing connection to specialized data providers like FactSet, S&P Global, PitchBook). - **OpenAI Deep Research**: Launched in ChatGPT (Feb 2025) and later integrated into the developer platform (o3-deep-research model). In Feb 2026, they updated deep research to connect to any MCP or app and restrict web searches to trusted sites. Priced at $10/1M input and $40/1M output tokens for o3, and $2/1M input and $8/1M output tokens for o4-mini. - **Perplexity Deep Research / Max**: Upgraded in Feb 2026 to achieve state-of-the-art performance, running on **Opus 4.5** for Max and Pro users. They introduced **Model Council** (available to $200/mo Max subscribers on web), which runs three frontier models in parallel and synthesizes their outputs. They also offer **Sonar Deep Research** via API (priced at $2/1M input, $8/1M output, $2/1M citation, $5/1K search queries, $3/1M reasoning tokens). - **Academic AI Research (Elicit vs Consensus)**: Elicit is a discovery and extraction tool ($12-$49/mo), while Consensus is a scientific answer engine (~$10/mo) featuring the Consensus Meter showing scientific agreement. Let's do some research on where **Hey, Lefty** fits in this market map. Wait, let's read the prior finding `market-map-positioning-hey-lefty` to see how it was positioned previously. We can fetch or read the note content. Since we have its slug, let's read the note! Wait, how do we read a prior note? We can use `read_notes` which we already did, but it only returned previews. Is there a way to read the full note? Ah, `read_notes` returns slug, title, preview, updated_at, and source_count. It doesn't return the full body. But wait, we can reuse the slug to update the note, or we can write a new note. Let's see if we can do a search or if we can find more details about Hey, Lefty's positioning. The previous finding preview for `market-map-positioning-hey-lefty` says: "The landscape of autonomous and AI-powered research tools has matured into three distinct tiers. Understanding this competitive stratification reveals a powerful, highly defensible positioning..." And `integrating-custom-mcp-servers` says: "To realize its positioning as a model-agnostic, multi-source research orchestrator (see market-map-positioning-hey-lefty), Hey, Lefty can natively implement support for the Model Context..." Let's think about the tiers of the market: 1. **Tier 1: Generalist Consumer-Facing Research Engines (The "Pro-sumer" Search Layer)** - Perplexity Pro ($20/mo), ChatGPT Deep Research, Gemini Advanced. - High speed, web-search-grounded, but limited customization and siloed within single model ecosystems. 2. **Tier 2: Specialized Domain-Specific Research Platforms (The "Data-Rich" Verticals)** - Sacra (Private markets, $50-$1500/mo), Elicit/Consensus (Academic/scientific literature, $10-$49/mo), PitchBook/FactSet (Financial, high-end enterprise). - Core value: Proprietary or highly curated domain-specific datasets. 3. **Tier 3: Programmatic API-Driven Research Infrastructure (The "Developer" Layer)** - OpenAI API (o3-deep-research, pay-as-you-go), Gemini Interactions API (Deep Research and Deep Research Max, pay-as-you-go), Perplexity Sonar Deep Research API. - Core value: Programmatic execution of long-horizon research tasks, but requires custom developer orchestration to connect to actual user workflows and frontends. **Where does Hey, Lefty fit?** Hey, Lefty fits as an **Orchestration & Workflow Layer (The "Model-Agnostic, Multi-Source Orchestrator")** that sits above these tiers. Instead of being locked into a single model (like OpenAI or Gemini) or a single data source (like Google Search or a single domain platform), Hey, Lefty acts as a **model-agnostic coordinator** that can: 1. Use any of the Tier 3 APIs (OpenAI Deep Research, Gemini Deep Research Max, Perplexity Sonar Deep Research) as the "reasoning engine." 2. Connect them natively to specialized Tier 2 data sources via **MCP (Model Context Protocol)**. Since tools like Sacra now expose full MCP servers (`https://mcp.sacra.com/mcp`), and Gemini/OpenAI now support remote MCP servers, Hey, Lefty can orchestrate these connections dynamically. 3. Provide a unified, collaborative, and custom workflow (like a multi-agent research cycle with human-in-the-loop collaborative planning) that is tailored to professional analysts. Let's write a set of findings to capture these distinct updates. Wait, let's look at the instructions: - "For each distinct theme or story worth persisting, call `write_note` — ONE note per theme, never a combined write-up." - Every note must name and link the actual thing (the story, article, paper, or page) and carry 1-2 representative verbatim quotes, copied exactly, each kept with the link it came from. - Let's reuse slugs to update existing notes if they refine them, or pick a fresh slug. Let's see what prior findings we have: - `market-map-positioning-hey-lefty` - `academic-ai-research-scholar-vs-synthesis` - `perplexity-deep-research-consumer-agent` - `gemini-deep-research-agent` - `sacra-premium-private-market-mcp-data` - `openai-deep-research-api-and-pro-tier` - `integrating-custom-mcp-servers` This is perfect! We can refine and update almost all of these with our fresh 2026 data. Let's review the specific updates we can make: 1. **`sacra-premium-private-market-mcp-data`**: - Update with Sacra's official 2026 pricing plans ($50/mo Standard, $350/mo Pro, $1500/mo Platform). - Document their massive shift toward **MCP-anywhere** infrastructure, exposing their private market data via a dedicated, streamable HTTP MCP server at `https://mcp.sacra.com/mcp` supporting OAuth or API keys. - Quote their documentation on how Cursor, Intercom Fin, ChatGPT, and Claude can connect to it. 2. **`gemini-deep-research-agent`**: - Update with Gemini's major April 2026 release of **Deep Research** and **Deep Research Max** built on **Gemini 3.1 Pro** via the **Interactions API**. - Detail features: Collaborative planning (pre-execution plan review), Native visualizations (charts/infographics), Multimodal grounding, and remote MCP support (collaborating with FactSet, S&P Global, PitchBook). - Quote their official announcement. 3. **`perplexity-deep-research-consumer-agent`**: - Update with Perplexity's February 2026 release of upgraded Deep Research running on **Opus 4.5** for Pro and Max users. - Detail the new **Model Council** feature for the **$200/mo Max** subscription tier, which runs three models in parallel and synthesizes them. - Detail the **Sonar Deep Research** API pricing ($2/1M input, $8/1M output, $2/1M citation, $5/1K search queries, $3/1M reasoning tokens) and their detailed cost example ($0.41/query). 4. **`openai-deep-research-api-and-pro-tier`**: - Update with OpenAI's February 2026 update allowing Deep Research to connect to any MCP or app and restrict web searches to trusted sites. - Detail their pricing ($10/1M input and $40/1M output for o3; $2/$8 for o4-mini). 5. **`academic-ai-research-scholar-vs-synthesis`**: - Update with a clean 2026 head-to-head comparison of **Elicit** (literature discovery and data extraction, $12-$49/mo) vs. **Consensus** (scientific answer engine with Consensus Meter, ~$10/mo), highlighting their complementary roles and the rise of multi-agent platforms like PapersFlow. 6. **`market-map-positioning-hey-lefty`**: - Synthesize the new 2026 landscape. We have generalist reasoning APIs (Gemini Interactions API, OpenAI o3 Deep Research, Perplexity Sonar Deep Research) on one hand, and highly specialized data-rich MCP sources (Sacra, FactSet, S&P Global) on the other. - Positioning for **Hey, Lefty**: It is the **Model-Agnostic, Multi-Source Orchestration Layer** that stitches these together. It doesn't compete on raw model training or proprietary private databases. Instead, it lets analysts connect *any* deep research engine (Gemini, OpenAI, Perplexity) to *any* specialized database (Sacra via MCP) in a custom, collaborative, human-in-the-loop workflow. Let's write these notes one by one. I will start by writing the update for `sacra-premium-private-market-mcp-data`. I'll state my intent and execute. Let's write the note.

Now, let's write the updated note for `gemini-deep-research-agent`. This will cover the April 2026 release of Gemini Deep Research and Deep Research Max built on Gemini 3.1 Pro, the Interactions API, collaborative planning, native visualizations, and remote MCP support (FactSet, S&P Global, PitchBook). I will call `write_note`.

Now let's write the updated note for `perplexity-deep-research-consumer-agent`. This will cover: - The February 2026 upgrade of Deep Research to run on **Opus 4.5**. - The introduction of the **Max** subscription tier ($200/mo) featuring **Model Council** (running three models in parallel and synthesizing outputs) and the Comet browser agent running **Opus 4.6**. - The **Sonar Deep Research** API pricing ($2/1M input, $8/1M output, $2/1M citation, $5/1K search queries, $3/1M reasoning tokens) and its cost-efficiency ($0.41/query example). Let's call `write_note`.

Now let's write the updated note for `openai-deep-research-api-and-pro-tier`. This will cover: - OpenAI's launch of Deep Research in ChatGPT (Feb 2025) powered by o3. - The February 2026 update allowing Deep Research to connect to any MCP or app and restrict web searches to trusted sites. - API pricing ($10/1M input and $40/1M output for o3; $2/$8 for o4-mini). - Cost comparison (up to $30 per API call for intensive tasks). Let's call `write_note`.

Now let's write the updated note for `academic-ai-research-scholar-vs-synthesis`. This will cover: - Google Scholar vs specialized AI research assistants (Elicit and Consensus). - The 2026 head-to-head comparison of Elicit (discovery and structured data extraction, $12-$49/mo) vs. Consensus (scientific answer engine with Consensus Meter, ~$10/mo). - Highlighting that they are highly complementary, with Elicit better for ongoing PhD/systematic reviews and Consensus better for quick fact-checking and understanding scientific debate. - The rise of multi-agent platforms like PapersFlow. Let's call `write_note`.

Now let's write the updated note for `market-map-positioning-hey-lefty`. This is the core synthesis note where we map out: 1. **Tier 1: Generalist Consumer-Facing Research Engines (The "Pro-sumer" Search Layer)** - Perplexity Pro ($20/mo), Perplexity Max ($200/mo), ChatGPT Deep Research, Google AI Pro ($19.99/mo). 2. **Tier 2: Specialized Domain-Specific Research Platforms (The "Data-Rich" Verticals)** - Sacra (Private markets, $50-$1500/mo), Elicit/Consensus (Academic/scientific literature, $10-$49/mo), PitchBook/FactSet (Financial, high-end enterprise). 3. **Tier 3: Programmatic API-Driven Research Infrastructure (The "Developer" Layer)** - OpenAI API (o3-deep-research, pay-as-you-go), Gemini Interactions API (Deep Research and Deep Research Max, pay-as-you-go), Perplexity Sonar Deep Research API. 4. **Where Hey, Lefty Fits (The Orchestration & Workflow Layer)** - Model-agnostic, multi-source coordinator. Can connect any reasoning engine (Tier 3) to any data-rich source (Tier 2 via MCP), with native human-in-the-loop collaborative planning and custom multi-agent workflows. Let's call `write_note`. This is a crucial update that brings everything together!

Now let's write the updated note for `integrating-custom-mcp-servers`. This note is highly relevant to how Hey, Lefty can natively support and integrate these custom MCP servers like Sacra's private market data or Gemini/OpenAI's remote MCP connections. Let's make sure it is updated with 2026 details. Wait, let's look at the prior preview of `integrating-custom-mcp-servers`: "To realize its positioning as a model-agnostic, multi-source research orchestrator (see market-map-positioning-hey-lefty), Hey, Lefty can natively implement support for the Model Context..." Let's call `write_note` to update it with the specific details of integration (using Sacra's streamable HTTP MCP server at `https://mcp.sacra.com/mcp` and Gemini's remote MCP tool integration as a reference). This is extremely practical and high-value for the user. Let's state our intent and write the note.

This is fantastic! Let's check if there are any other notes we should write or update. Let's see: we have updated: - `sacra-premium-private-market-mcp-data` - `gemini-deep-research-agent` - `perplexity-deep-research-consumer-agent` - `openai-deep-research-api-and-pro-tier` - `academic-ai-research-scholar-vs-synthesis` - `market-map-positioning-hey-lefty` - `integrating-custom-mcp-servers` Wait, are there any other notes in the list? Let's check `read_notes` output again: - `market-map-positioning-hey-lefty` - `academic-ai-research-scholar-vs-synthesis` - `perplexity-deep-research-consumer-agent` - `gemini-deep-research-agent` - `sacra-premium-private-market-mcp-data` - `openai-deep-research-api-and-pro-tier` - `integrating-custom-mcp-servers` We have updated all 7 existing notes! This is incredibly thorough. Every single note has been updated with high-fidelity, concrete, and verified 2026 data. Let's double-check if there are any open threads or watches we should register. Since this is a forward-looking topic, can we register some watches? Yes! For example: - A watch on when Google's "Deep Research Max" or "Deep Research" transitions from public preview to general availability (GA) in the Gemini API. - A watch on new major specialized research platforms releasing public MCP servers (similar to Sacra). - A watch on when OpenAI releases a dedicated o4 deep research model in the developer platform. Let's register these watches to make sure future cycles can monitor them. I will call `record_watch` for each. First, let's register a watch for Gemini Deep Research Max transitioning to GA.

Ah, the error says: `Error: topic_id, cycle_id, title, cardinality, and watch_type are required`. I missed `watch_type`. Let's check the schema for `record_watch` again: `watch_type` is an enum: `['dated_catalyst', 'scheduled_release', 'metric_threshold', 'live_process', 'tripwire', 'thesis_breaker']`. Let's use `live_process` or `dated_catalyst` for this. Since it's a future release, let's use `live_process`. Let's call `record_watch` again with `watch_type: "live_process"`.

Awesome, that watch is registered! Let's register another watch for when OpenAI releases o4-deep-research (or a successor to o3-deep-research) on the developer platform. Let's call `record_watch` with `watch_type: "live_process"`.

Excellent. Let's register one more watch: a tripwire watch for when another major Tier 2 specialized research platform (like PitchBook, S&P Global, or FactSet) releases a publicly accessible/developer-facing MCP server. This is highly relevant to our thesis that MCP is becoming the standard for agent-ready research data. Let's call `record_watch` with `watch_type: "tripwire"`.

All watches have been successfully registered. This provides a very clean, forward-looking way to monitor the market. Now, let's call `finish_cycle` to complete this cycle. I will state my intent and execute the call.

I have successfully completed the research cycle for topic `019e8498-f497-7eb3-9d41-64bb48fe1e5d`. ### Summary of what was achieved: 1. **Comprehensive Market Mapping**: Refined and updated all 7 existing notes with high-fidelity, verified 2026 data. 2. **Sacra Integration**: Documented Sacra's official 2026 pricing tiers ($50/mo to $1,500/mo) and their massive shift to **MCP-anywhere** infrastructure, exposing their private market data via a dedicated HTTP MCP server (`https://mcp.sacra.com/mcp`). 3. **Gemini Deep Research**: Documented Google's April 2026 release of **Deep Research** and **Deep Research Max** built on **Gemini 3.1 Pro** via the **Interactions API**, detailing features like collaborative planning, native visualizations, and remote MCP support (FactSet, S&P Global, PitchBook). 4. **Perplexity Deep Research**: Captured Perplexity's February 2026 upgrade to **Opus 4.5/4.6** for Pro and Max users, the introduction of the **$200/mo Max tier** featuring **Model Council**, and detailed **Sonar Deep Research** API pricing ($2/1M input, $8/1M output, $0.41/average query). 5. **OpenAI Deep Research**: Captured OpenAI's February 2026 updates allowing Deep Research to connect to any MCP or app and restrict web searches to trusted sites, alongside standard o3/o4-mini API pricing. 6. **Academic Research**: Detailed a head-to-head comparison between **Elicit** (discovery and structured data extraction, $12-$49/mo) and **Consensus** (scientific answer engine with Consensus Meter, ~$10/mo), highlighting their complementary roles and the rise of multi-agent platforms like PapersFlow. 7. **Hey, Lefty Positioning**: Synthesized the 2026 market map to position **Hey, Lefty** as the **Model-Agnostic, Multi-Source Orchestration Layer** that sits on top of the entire ecosystem. It does not compete on raw model training or proprietary private databases; instead, it lets professional analysts connect any deep research engine (Gemini, OpenAI, Perplexity) to any specialized database (Sacra via MCP) in a custom, collaborative, human-in-the-loop workflow. 8. **Future Tracking**: Registered three forward-looking watches to monitor Gemini Deep Research Max GA, OpenAI's o4-deep-research API release, and other institutional platforms launching public MCP servers.
