Description
OpenCode's GitHub Copilot model picker does not include "Claude Opus 4.6 (1M context)" as a selectable option, while VS Code's GitHub Copilot does expose it.
Current behavior
The GitHub Copilot provider in OpenCode lists claude-opus-4.6 with 144K context only. There is no 1M context variant available.
Expected behavior
A separate "Claude Opus 4.6 (1M context)" model should appear in the model picker, matching what GitHub Copilot exposes in VS Code.
Root cause
The models.dev registry only defines a single claude-opus-4.6 entry under the github-copilot provider with context: 144000. The 1M context variant needs to be added as a separate model entry.
Screenshots
OpenCode — no 1M context option:
VS Code GitHub Copilot — shows "Claude Opus 4.6 (1M context)":

Research direction
Start by locating the models.dev registry entry for the github-copilot provider and reviewing the existing claude-opus-4.6 definition with context: 144000. Add the separate 1M-context model entry so it appears in the GitHub Copilot model picker, matching the option exposed by VS Code.
