Description

Claude Opus 4.6 (fast mode) is available in GitHub Copilot
(30x multiplier, Preview status) but is missing from the
github-copilot provider in models.dev.

This causes OpenCode to not display this model in the /models list.

The model is confirmed available via gh copilot CLI model selection.

Suggested file: providers/github-copilot/models/claude-opus-4-6-fast.toml

Ref: https://docs.github.com/en/copilot/reference/ai-models/supported-models

Research direction

Compare neighboring files in providers/github-copilot/models/ to confirm the TOML fields and naming conventions, then check the GitHub Copilot supported-models reference. Done means adding claude-opus-4-6-fast.toml with the 30x multiplier and Preview status so the model appears in OpenCode's /models list.
