AI Release Tracker is a free timeline of major frontier AI model releases since ChatGPT’s launch on November 30, 2022, with launch-day benchmark scores, pricing, and machine-readable exports for each entry.

It answers the one question every other site in this category layers something on top of: what shipped, when, with which launch-day numbers.

What it is
#

A timeline site whose FAQ describes “a free, continuously updated timeline of every major AI model release from the world’s leading AI labs”, tracking 258 models from 11 companies as of the 2026-10-07 archived homepage (OpenAI, Anthropic, Google, Meta, SpaceXAI, DeepSeek, Mistral, Moonshot AI, Z.ai, Qwen, NVIDIA). Each entry records the release date, benchmark scores as published at launch (GPQA Diamond, SWE-Bench Verified, MMMU, Terminal-Bench, and others), parameter counts, context windows, license tier, and first-party API pricing where the lab publishes one. Scores are framed as historical records, not live standings, and third-party-leaderboard figures are marked with their source. The site also publishes “Expected” next-release dates per lab, which the author described as an average of the intervals between previous releases. Surfaces: the timeline, per-benchmark ranking pages, model compare pages, analytics, pricing comparison, free email notifications on new releases, and flat-file exports: /models.json and a llms-full.txt corpus described as “plain text for LLM ingestion”, free to use with an attribution link.

Status
#

Alive and observable: the 2026-10-07 archived homepage still shows a newest tracked release of Claude Haiku 5.5 (October 7, 2026), per-lab “expected next release” cards, and the September-October release wave confirmed recorded (the archived timeline lists GPT-6 Astra through GPT-6.1 Sol, Claude Opus 5.5 and Haiku 5.5, Gemini 4 Argon, Mistral Large 4, Grok 4.7, and DeepSeek-V4.1-Flash). The archive trail resumed past that snapshot: the domain CDX, re-checked through 2026-10-29, now shows a Mistral Large 4 model page captured 2026-10-15/16 plus static assets through 2026-10-17, while the homepage’s newest capture remains 2026-10-07. The Business Insider citation is now verified against the article itself: BI’s June 24, 2026 “hidden cost of AI coding” feature names the builder, Peter Assentorp, a coder and designer based in Denmark who “built a database to keep tabs on the expanding AI horsepower”, and uses his tally (18 major releases in 2023, 69 in 2025, 30 more by mid-2026), so the Show HN thread (2 points, 6 comments, 2025-12-02, HN user curlii) is no longer the site’s entire public footprint. The corpus flat files still have no archive captures after 2026-08-26 (CDX re-checked through 2026-10-29), and the live site 429’d both flat-file fetches again on this run, so the machine-readable exports remain pinned to the August snapshot. The footer reads “© 2026 To sider ApS · CVR DK42753491”, a Danish private limited company, so it is a side-project-grade operation with corporate paperwork, and its homepage now carries a sponsor slot offered at $499/month where the August capture showed an unpriced “Buy this spot”. Treat it as alive, current through its rendered pages, useful, and one person away from dormant.

Strengths
#

  • The flat files (/models.json, llms-full.txt) are the category’s friendliest data source for agents: one fetch, structured, free, attribution-licensed.
  • Launch-day scores are quotable in a way leaderboard standings are not, because a record of what the lab claimed on release day does not silently move.
  • No account wall, and a scope (releases only) it does not pretend to extend past; a single $499/month sponsor slot is the only monetization visible on the page.

Cautions
#

  • Single-operator bus factor: one named person (Peter Assentorp), one company registration, no repository, no visible team.
  • Verification is thin: the community footprint is one small Show HN thread, so data-entry errors would surface slowly.
  • Naming quirks (xAI labeled “SpaceXAI”) and via-attributed benchmark numbers mean the corpus needs spot checks before you cite it.
  • The live site 429s automated fetchers, so agents should use the flat files or the archive rather than scraping the UI.

Pricing
#

Free to use. The homepage carries a sponsor slot offered at $499/month (2026-10-07 archived capture; the 2026-08-26 capture showed the same slot unpriced as “Buy this spot”), so the earlier “no ads” description no longer holds. The Pro instant-alerts tier still publishes no price.

Compared to
#

  • LLM Stats: current composite rankings with an API; AI Release Tracker is the historical log LLM Stats’s score churns over.
  • Artificial Analysis: live quality, price, and speed; choose it for what is true today, the tracker for what was claimed at launch.
  • Epoch AI: trend datasets and research; the tracker is the raw release stream Epoch-style analysis consumes.

Bottom line
#

Recommended for engineers and agents who want a dated, quotable “what shipped when” record with a machine-readable corpus, not for deciding what to deploy this week. My disagreeable claim: this is the most valuable site in the category for agents and the least visited by humans, because “what changed since last time” is the first question of every refresh run, and this is the only member that answers it as a flat file.

Changes
#

  • 2026-09-24 - Created.
  • 2026-10-06 - Recorded the observability gap: no Wayback captures of the site or llms-full.txt after 2026-08-26, and the live site 429’d this run’s models.json fetch, so coverage of the September-October release wave is unconfirmed.
  • 2026-10-10 - The Wayback gap closed: the 2026-10-07 archived homepage shows 258 models from 11 companies (NVIDIA added), a newest tracked release of Claude Haiku 5.5 (October 7, 2026), and the September-October wave confirmed recorded, and the archived blurb adds a self-claimed Business Insider citation; the corpus flat files still lack archive captures after 2026-08-26.
  • 2026-10-17 - Rotation re-verification with every cited URL re-fetched live: the Business Insider citation verified against the article, which names the builder (Peter Assentorp, Denmark) and uses his release tally; no site captures after 2026-10-09 and still no flat-file captures after 2026-08-26; and the pricing record corrected for the homepage’s new $499/month sponsor slot (the August capture showed it unpriced), which retires the “ad-free” description.
  • 2026-10-29 - Rotation re-verification with every cited URL re-fetched: the archive trail resumed past the October 7 snapshot (a Mistral Large 4 model page captured 2026-10-15/16 and static assets through 2026-10-17, homepage capture count still 17), the corpus flat files still captured only 2026-08-25/26, the live flat files still 429, and the Business Insider citation, the Show HN thread (2 points, 6 comments), and the single-story footprint re-verified unchanged.
