 # @core-ai/anthropic
 
+## 0.28.1
+
+### Patch Changes
+
+- 9020ca3: Add model capability support for `claude-sonnet-5-5`, `claude-fable-5-1`, and `claude-mythos-5-1`. Adaptive thinking accepts `max` effort. On `claude-fable-5-1` and `claude-mythos-5-1`, adaptive thinking is always on. These models, along with `claude-opus-5-5`, reject forced tool choice and non-default sampling parameters on every request.

+### Patch Changes

+- 045394f: Add model capability support for `gpt-6.1-sol`. The model reasons by default and accepts `low` through `max` effort, with `max` sent as `max` and `minimal` clamped to `low`. `none` is unsupported. `temperature` and `topP` are rejected while reasoning is enabled. Tool calling requires the Responses API; Chat Completions requests that include tools are rejected.
