时间线
2026年7月
A Mythos-class model made safe for general use — Anthropic's most capable generally available model, sitting above the Opus tier.
为何重要: The frontier of general-purpose reasoning just moved again; capable assistants keep getting cheaper to match.
2026年6月
The Mythos-class model available to approved organizations without the general-use safety measures applied to Fable 5.
为何重要: Signals how fast the top tier is advancing — the same capability reaches everyone shortly after.
2026年5月
A strong all-round released model, widely cited as a top performer through mid-2026.
为何重要: A dependable default for hard reasoning, coding, and long-document work.
OpenAI's mid-2026 frontier update, trading the top spot with Claude Opus on many benchmarks.
为何重要: Keeps the price-for-capability race moving — good news for anyone paying per token.
2026年3月
A March 2026 frontier release with a 1M-token context window and strong computer-use scores.
为何重要: Million-token context means it can read whole manuals, contracts, or codebases at once.
An open-weights frontier model with a 1M+ token context window and strong coding scores.
为何重要: Open weights + very low cost make it the value pick for budget-conscious and privacy-sensitive setups.
2026年2月
Google's February 2026 frontier update to the Gemini 3 line, with a very large context window.
为何重要: Deep integration with Google Workspace makes it a natural fit if you live in Docs and Gmail.
A February 2026 iteration in the GPT-5 line ahead of the March 5.4 release.
为何重要: Part of the steady cadence keeping the mainstream assistant sharp.
A February 2026 Opus update (alongside Sonnet 4.6), continuing Anthropic's rapid iteration.
为何重要: Reliability gains at the same price point — worth re-testing your prompts on each bump.
2025年11月
The Gemini 3 flagship that opened the current generation for Google.
为何重要: Set the bar for long-context multimodal work heading into 2026.
A late-2025 Opus release that anchored Anthropic's top tier into 2026.
为何重要: The baseline many businesses standardized on before the 2026 wave.
