@ai-sdk/anthropic@3.0.120

Patch Changes

• bd8bf1f: feat(anthropic): add Claude Opus 5.5 support

  • add the claude-opus-5-5 model ID to @ai-sdk/anthropic and anthropic/claude-opus-5.5 to @ai-sdk/gateway
  • models that always use adaptive thinking (claude-opus-5-5, claude-fable-5, claude-fable-5-1) no longer receive thinking: { type: 'disabled' } or budget-based thinking; the provider drops the unsupported setting and emits a warning
  • models that reject forced tool use (claude-opus-5-5, claude-fable-5-1) fall back to auto tool choice for required and named tool choices, and to native structured outputs when structuredOutputMode: 'jsonTool' is requested, each with a warning
  • add the computerToolset_20260801 computer use tool (computer_toolset_20260801), which is required for computer use on claude-opus-5-5
  • use the documented mid-conversation-output-config-2026-07-01 beta header for per-message effort
