$ tail -f /var/log/acceleration The AI acceleration timeline — frontier model releases, dated and sourced

Every frontier model release, compute buildout and culture moment since the movement got its name — newest first, every entry sourced. Updated weekly. The live counters on the homepage run on this same data, and the token cost calculator prices the models listed here.

$ tail -n 16 /var/log/acceleration The full AI acceleration log, 2022–2026

1. 2026-06-09 MODEL

   Claude Fable 5 ships

   Anthropic opens the Claude 5 family: always-on adaptive thinking and a 1M-token context window.

2. 2026-04-23 MODEL

   GPT-5.5 ships

   OpenAI's flagship update lands in ChatGPT and Codex; API access follows a day later.

3. 2025-11-24 MODEL

   Claude Opus 4.5 ships

   Anthropic's strongest coding model to date lands days after Gemini 3 — the frontier cadence compresses to weeks.

4. 2025-11-18 MODEL

   Gemini 3 ships

   Google's frontier line jumps again; agentic coding and long-horizon tasks improve another step.

5. 2025-11-12 MODEL

   GPT-5.1 ships

   OpenAI iterates the GPT-5 line with adaptive reasoning effort and faster default paths.

6. 2025-08-07 MODEL

   GPT-5 ships

   OpenAI unifies reasoning and fast paths behind one router; frontier access goes mass-market.

7. 2025-05-22 MODEL

   Claude 4 ships

   Anthropic's Opus 4 and Sonnet 4 push sustained autonomous coding into production use.

8. 2025-01-21 COMPUTE

   Stargate announced: $500B

   SoftBank, OpenAI, Oracle and MGX commit $500B over four years — $100B deploying immediately — for US AI datacenters.

9. 2025-01-20 MODEL

   DeepSeek-R1 open weights

   Frontier-class reasoning released under MIT license at a fraction of incumbent training cost.

10. 2024-09-12 MODEL

    OpenAI o1: the reasoning era

    Test-time compute becomes the new scaling axis — models that think before they answer.

11. 2024-05-13 MODEL

    GPT-4o: omni goes realtime

    Native audio-vision-text at half the price of GPT-4 Turbo. Frontier intelligence keeps getting cheaper.

12. 2024-03-04 MODEL

    Claude 3 ships

    Opus matches GPT-4; for the first time the frontier is contested by more than one lab.

13. 2023-10-16 CULTURE

    The Techno-Optimist Manifesto

    Marc Andreessen publishes the manifesto; e/acc ideas enter mainstream venture discourse.

14. 2023-03-14 MODEL

    GPT-4 ships

    The capability jump that reset every timeline. $30 per million input tokens at launch.

15. 2022-11-30 MODEL

    ChatGPT launches

    100M users in two months. The acceleration becomes visible to everyone.

16. 2022-05-31 CULTURE

    e/acc is born

    A pseudonymous newsletter by @zestular, @BasedBeffJezos, @bayeslord and co. names the movement: build, accelerate, ascend the Kardashev gradient.
