## Summary Adds Anthropic Claude Fable 5 as a first-class Fabro model without changing the default Anthropic model. The catalog now exposes `claude-fable-5` with `fable` and `claude-fable` aliases, 1M context, 128k max output, effort levels, vision/tools, prompt caching, and the documented pricing. The Anthropic adapter now handles Fable's API behavior directly: it uses the `claude-fable-5` API ID, omits the legacy 1M context beta header, avoids injecting default `thinking`, preserves `output_config.effort`, omits deprecated `temperature`/`top_p` sampling fields for Fable, and rejects unsupported manual enabled/disabled thinking configs locally. Fable refusals are converted into content-filter LLM errors with `stop_details` preserved. Those refusal errors are fallback-eligible, so existing `run.model.fallbacks` chains work for both prompt and agent paths, while no-fallback refusals surface clearly as LLM errors. ## Live QA Manually exercised the PR branch against a live Anthropic API key from `~/.fabro.bak/.env.bak` using a temporary local harness that was removed before commit. The run covered non-streaming completion via `fable`, token counting via `claude-fable`, streaming completion, the deep model-test path with tools/reasoning, local rejection of manual thinking config, and a live refusal probe. The live run initially exposed Anthropic's Fable rejection of `temperature`; this PR now strips deprecated sampling fields for Fable and the live harness then passed 6/6 checks. ## Testing - `cargo test -p fabro-llm --test live_fable_manual -- --nocapture --test-threads=1` -> 6 passed against live Anthropic, temporary harness removed afterward - `cargo nextest run -p fabro-llm encode_fable_uses_api_id_effort_and_omits_1m_beta` - `cargo nextest run -p fabro-model -p fabro-llm -p fabro-workflow` -> 1808 passed, 41 skipped - `cargo +nightly-2026-04-14 fmt --check --all` - `cargo insta pending-snapshots` -> no pending snapshots - `git diff --check` --------- Co-authored-by: Claude Fable 5 <noreply@anthropic.com> |
