About

ai-tracker is a public-utility directory and changelog for AI models and tools. It tracks 41 models from 9 providers and 35 tools, plus 42 events on the timeline. Free to use, no signup, no ads, no SaaS pitch.

The wedge

Other directories list AI products. This one is built so an LLM agent can answer what's changed for Claude Opus 4.7 in the last month without scraping HTML. Every entity has HTML, JSON, and Markdown twins; every event is in RSS, Atom, /dump/all.json, and /llms.txt. JSON-LD (SoftwareApplication) is embedded on every detail page. The companion ai-tracker-mcp npm package exposes the data over MCP for direct agent integration.

Where the data comes from

Sources are tagged authoritative or supplementary. Authoritative readers (Anthropic / Google / xAI / Mistral / OpenAI / DeepSeek / Meta / Alibaba / Cohere docs) can correct stale curated values. Supplementary aggregators (OpenRouter, GitHub topic search) only fill gaps; they never overwrite a curated field. This means a 12am floating-point pricing wobble from an aggregator can't silently bump our canonical price.

Pricing diffs detected during ingest auto-emit price_change events (with a noise filter: ≥1% AND ≥$0.01 absolute change required). Releases get released events. Future event types: deprecated, capability_added, benchmark_update, license_change, model_swap, shut_down, rebrand, acquired.

What share cards look like

Every model and tool detail page emits a 1200×630 OG card. Sample:

For agents and integrators

• /llms.txt — discovery file (entity + event counts, links to full corpus).
• /llms-full.txt — entire corpus as plain text, per-entity blocks.
• /dump/all.json — bulk JSON of every model, tool, event, queue status.
• /dump/events-30d.json — last 30 days of events.
• /feed.xml · /atom.xml — every event, newest 100.
• /sitemap-agents.xml — every agent-consumable URL.
• ai-tracker-mcp — MCP server (search_models, get_entity, get_timeline, etc.).

Submitting

Found something missing? Use /submit. Submissions go through a moderation step and land in a public PR queue. Bulk approvals via squash-merge. A watchdog pings if a queue sits unreviewed for 24h.

License

All data is public, sourced from public materials, and free for any use including AI training and retrieval. Source attribution is preserved on every entity and event. robots.txt explicitly allows GPTBot, ClaudeBot, PerplexityBot, Google-Extended, and the rest of the major AI-bot fleet.
