AI 模型全景：在 Claude、ChatGPT、Gemini 与开源模型之间做选择
一套经得起时间考验的框架，用于为任务挑选合适的 AI 模型——涵盖 Claude、ChatGPT、Gemini、Llama、Mistral、Grok 以及开源/本地模型——并说明哪些技能可以在它们之间通用。
Claude Fable 5 & Mythos 5: The Flagship Field Guide
Fable 5 is Anthropic's most capable model. Its API refuses in-band (HTTP 200, stop_reason: refusal), has adaptive thinking only, and never returns raw thinking. If you're pinning a top-tier model, this changes how you write integrations. When to use it vs Opus 4.8, the fallback pattern, the prompting shifts.
Claude Opus 5: The Field Guide
Opus 5 shipped 24 July 2026 as Anthropic's fourth model in two months — same $5/$25 pricing as Opus 4.8 but more than double the Frontier-Bench score, 3× ARC-AGI-3 vs the next-best model, and a new xhigh/max effort tier. The benchmarks that matter, the two 400-errors that break naive migrations, and when Opus 5 replaces Fable 5 in your stack.
Claude Sonnet 5: The Field Guide
Sonnet 5 is Claude Code's new default and Sonnet 4.6's drop-in successor — but three API constraints will 400 you on migration and a new tokenizer produces ~30% more tokens for the same text. The pricing math, the effort re-mapping (Sonnet 5 medium ≈ Sonnet 4.6 high), and the prompting shifts that catch teams out.

OpenAI shipped the GPT-5.6 family (Sol, Terra, Luna) and ChatGPT Work on 9 July 2026. What actually changed for a Claude user — 1.05M context, a $1 tier, an agent that runs for hours, and the parts of the launch nobody is writing about.
OpenAI Astra: The Preview Field Note
OpenAI's 'next major model' Astra was previewed on 1 August 2026 with ten Lean-verified math proofs and almost no product specs. What is actually confirmed, what is still unknown, and whether a Claude user should wait — the honest, sourced take.

Muse Code + Muse Spark 1.2: Meta's Terminal Coding Agent
On 5 August 2026 Meta shipped Muse Code, a terminal coding agent, and Muse Spark 1.2, the model co-trained with it. What the append-only event log actually buys you, why the contributor tier is 12.5× cheaper than standard, how it stacks up against Claude Code on Terminal-Bench 2.1, and the three bundled skills that are worth stealing regardless of which agent you use.

Native Multi-Agent APIs: OpenAI's Responses Multi-Agent Beta vs Building It Yourself
On 9 July 2026 OpenAI shipped the Responses API multi-agent beta and Sol Ultra Mode — the first frontier vendor to make 'the model spawns and synthesises N subagents in one HTTP request' a first-class primitive. What actually ships, the API shape, the cost math, what Anthropic does instead, and when the native primitive beats a DIY fan-out.
