Monthly AI timeline
The AI Era
This timeline is designed as a month-by-month record of the AI era rather than a loose collection of milestones. The June 14, 2026 refresh now carries the timeline through the latest mid-June releases.
Use it when you want sequence, not just significance. A lot of AI discussion collapses events together. This page is built to show how model launches, product shifts, infrastructure moves, and agent patterns accumulated over time.
What is included
The emphasis is on the modern period from GPT-3 onward: major model releases, reasoning shifts, agent tooling, open-weight frontier moves, speech and multimodal infrastructure, and the broader transition from chat interfaces to more capable operating layers.
Current snapshot
The newest entries cover Kimi K2.7-Code raising the open coding-floor watchlist, GLM-5.2 arriving for Z.AI Coding Plan users with public weights promised next week, Claude Fable 5 replacing Opus 4.8 as the public measured ceiling, Claude Mythos 5 showing the same capability tier under trusted-access restrictions, and the earlier June wave around North Mini Code, Gemma 4 12B, DiffusionGemma, MiniMax M3, Qwen3.7 Plus, speech models, and NVIDIA's Nemotron 3 Ultra open-weight flagship.
How to read it
Treat it as a chronology first and a commentary surface second. It works best alongside the broader architectural pieces on the site, because the question is not only what launched, but what each launch changed in the way people work with AI.
