llm-anthropic 0.31
AI guide
The llm-anthropic plugin has been updated to version 0.31, adding API support for Anthropic Fable 5.2 and Mythos 5.2. Users can configure API keys via the CLI and test different reasoning levels. During an SVG generation test with Fable 5.2, the author found that the 'max' reasoning setting exhausted its limit after consuming 128,000 thinking tokens and failed to return a response—an edge case previously observed with Opus 5.5.
Why it matters
The author updated the CLI plugin and tested various reasoning tiers, demonstrating an edge-case failure where the 'max' setting exhausted a massive budget of thinking tokens.
