ChatGLM-6B was Zhipu's first publicly accessible flagship chat product (ran locally on a single consumer GPU, and via a public web demo).

Ultra first became publicly available Feb 8, 2024 as the model behind the new Gemini Advanced subscription (Google One AI Premium, $19.99/mo); that availability date is recorded here as the release date per project convention. GPQA was not reported for Ultra in either the announcement or the technical report. GSM8K legacy score added from the technical report's prose (Section on math benchmarks); HellaSwag was not added despite being requested because the report's own multi-column comparison table renders too ambiguously via both pdftotext and r.jina.ai to confidently attribute a decontaminated 10-shot figure to Gemini Ultra specifically (the report separately warns that a naive contaminated evaluation reads 96.0%, which this project deliberately does not use)."

That Q1 2026 window has since passed without a release; by mid-2026 xAI shipped intermediate models (Grok 4.5, Grok 4.6) instead, and public reporting as of Aug 2026 places Grok 5 training on the newer 'Colossus 2' cluster with no firm date — xAI has not published a revised official date, so expected_window above reflects only the original Nov 2025 statement and is now stale."

Counted as released per project convention since it was immediately publicly usable, mirroring the treatment of Gemini 2.0/2.5 Pro Experimental. The launch post itself gives only the ARC-AGI-2 number and the PDF model card's benchmark table is an image, but the live deepmind.google/models/gemini/pro comparison page (re-fetched 2026-09-07) renders the same benchmark table as plain HTML, from which HLE, GPQA Diamond, Terminal-Bench 2.0, SWE-bench Verified, τ2-bench (Retail/Telecom) and MMMU-Pro were recovered — resolving the gap flagged in earlier research on this release. LiveCodeBench is reported on that page only as 'LiveCodeBench Pro' Elo rating (2887), a different scale incompatible with this project's 0-100 pass@1 metric, so it is not recorded."

On June 12, 2026 the US government briefly applied export controls to both models, suspending access; access was restored June 30-July 1, 2026 (see the 'Redeploying Claude Fable 5' source). This generation's system card treats GPQA Diamond as saturated and stopped reporting it for Fable 5 specifically (Mythos 5 alone is given at 94.1%, 'averaged over 5 trials'); MMLU/MATH/HumanEval/MMMU are no longer reported for either model, and Terminal-Bench has moved to version 2.1 (not this basket's 2.0), so none of those appear as scores here. Family is recorded as 'Claude Fable' per this project's lineage-fork convention, even though the Opus line (Claude Opus 4.8, and subsequently a further 'Claude Opus 5', per the Fable 5.1 system card's comparison table) continued in parallel rather than being replaced."

Mythos 5.1 remains restricted to vetted cyberdefense/life-sciences partners via trusted access programs (not public). The same comparison table lists a 'Claude Opus 5' column (system card dated July 24, 2026 per public reporting), confirming the Opus numbered line continued past 4.8 in parallel with the Fable/Mythos lineage; it is not separately researched/recorded in this file given the time budget for this pass. GPQA Diamond, MMLU, MATH and HumanEval are no longer reported by Anthropic for this generation (GPQA was declared saturated as of the Fable 5/Mythos 5 system card); Terminal-Bench has moved to versions 4.0 and 'Science 0.1', neither comparable to this basket's Terminal-Bench 2.0, so no terminal-bench-2 score is recorded."
