Release: llm-anthropic 0.31
Simon Willison 发布 llm-anthropic 0.31，新增对 Anthropic 当日推出的 Fable 5.2 和 Mythos 5.2 的支持，可通过 `llm -m claude-fable-5.2` 调用。在 low 到 max 五档推理强度测试中，max 档耗尽 128,000 token 仍未返回图像，与 Opus 5.5 的旧问题相同，而 Fable 5 和 5.1 的 max 档此前正常。

Release llm-anthropic 0.31 — LLM access to models by Anthropic, including the Claude series
Anthropic released Fable 5.2 and Mythos 5.2 today. I've added them to llm-anthropic, so you can now run prompts through Fable 5.2 like this:
uv tool install llm llm install llm-anthropic llm keys set anthropic # paste key here llm -m claude-fable-5.2 "Generate an SVG of a pelican riding a bicycle"
I ran pelicans at all five reasoning levels - low, medium, high, xhigh, and max. You can see them all here - here's the best result I got, from xhigh:
max failed to return an image at all, running out of tokens after spending 128,000 thinking about them. That's the same bug that I saw with Opus 5.5 - but it's new for the Fable series, both Fable 5 and Fable 5.1 returned max effort pelicans just fine.
