Grok 5 will be out before the end of this year and it will be crushingly good.

Grok 5 was not released in 2025. xAI said on 6 Jan 2026 that Grok 5 was “currently in training”; as of 1 Nov 2026 xAI’s API release notes list Grok 4.7 (21 Sep 2026) as the newest model and no Grok 5.

With Grok 5, which should be out before the end of this year, we will be incorporating the entire corpus of SpaceX data.

Not released as of 1 Nov 2026; xAI has announced no release date. Earlier targets (end of 2025, Q1 2026) passed.

The @xAI Grok 2.5 model, which was our best model last year, is now open source. Grok 3 will be made open source in about 6 months.

Grok 2.5 weights were released (xai-org/grok-2). Musk reaffirmed Grok 3 would be open-sourced in Feb 2026, but as of 1 Nov 2026 xAI’s Hugging Face organisation lists only grok-1 and grok-2; we found no official Grok 3 weights.

The @xAI goal is 50 million in units of H100 equivalent-AI compute (but much better power-efficiency) online within 5 years.

Deadline not reached. For scale, Epoch AI estimated Colossus 2 at roughly 1.1 million H100-equivalents in September 2026 (as reported by AI Prediction Index).

The Colossus 2 supercomputer for @Grok is now operational. First Gigawatt training cluster in the world. Upgrades to 1.5GW in April.

Epoch AI’s satellite analysis (Jan 2026) found about 350 MW of cooling capacity, disputing the 1 GW claim; Epoch’s September 2026 estimate of about 946 MW of IT power (reported by AI Prediction Index) means the 1.5 GW April upgrade did not happen on time.

Version 0.1 early beta of Grokipedia will be published in 2 weeks

Delivered 8 days late. Musk set the two-week target on 5 Oct 2025, postponed the launch on 21 Oct, and Grokipedia v0.1 went live on 27 Oct 2025 with about 885,000 articles.
