feat(LAC-3106): add Claude Opus 5 and set it as default Anthropic model - #492
Merged
Conversation
Claude Opus 5 (`claude-opus-5`) was released 2026-07-24 as the new flagship Opus-tier model (Opus-4.8 pricing, adaptive thinking, 1M context). Verified against live Anthropic model docs per the weekly model-update check. - Add CLAUDE_OPUS_5 constant to model_ids - Include it in OPUS_4_5_PLUS_MODELS so it uses the 2025-11-24 computer-use beta (computer_20251124 + text_editor_20250728) - List it first and mark it the sole recommended (default) Anthropic model; demote Opus 4.8 to non-recommended - Update the empty-definitions fallback constant to Opus 5 - Add tests: default-model selection and tool-type remapping - Refresh stale CLI --model help example (claude-opus-4-7 -> claude-opus-5) Frontend needs no change: model selectors are populated dynamically via get_provider_models (zero hardcoded IDs). Verified with cargo test on the agent::providers::types module (13/13 pass). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

No change required. Model selectors are populated dynamically via
invoke("get_provider_models")→get_model_info()→model_definitions(); grep ofsrc/found zero hardcoded model IDs, so the UI picks up Opus 5 automatically with the correct recommended badge.Verification
