Model capability probe

Anthropic: Claude Opus 4.6 (Fast) | embeddings

Whether Anthropic: Claude Opus 4.6 (Fast) supports embeddings cannot be decided from the name alone. Check model ID anthropic/claude-opus-4.6-fast, provider Anthropic, catalog params, modality, a lightweight runtime probe, and the error body together.
