# Copilot API Proxy for Claude Code and Codex

> **Note:** The recommended model is `claude-opus-4.6-1m` which supports 1M context window. If your tool doesn't support specifying `claude-opus-4.6-1m`, you can use `claude-opus-4.6` instead - the proxy will automatically map it to the correct model.
### Server-side Claude model overrides
Claude Code's model picker only knows Anthropic model names. If you want to force a Claude family to a specific Copilot model id, set one of these environment variables when you start the proxy:
| Environment variable | Applies to incoming model names containing | Example target |
| ------------------------- | ------------------------------------------ | ------------------------------ |
| `COPILOT_OVERRIDE_OPUS` | `opus` | `claude-opus-4.7-xhigh` |
| `COPILOT_OVERRIDE_SONNET` | `sonnet` | `claude-sonnet-4.6` |
| `COPILOT_OVERRIDE_HAIKU` | `haiku` | `claude-sonnet-4.6` |
macOS/Linux, one command:
```sh
COPILOT_OVERRIDE_OPUS=claude-opus-4.7-xhigh COPILOT_OVERRIDE_HAIKU=claude-sonnet-4.6 bun run start
```
macOS/Linux, current shell session:
```sh
export COPILOT_OVERRIDE_OPUS=claude-opus-4.7-xhigh
export COPILOT_OVERRIDE_HAIKU=claude-sonnet-4.6
bun run start
```
PowerShell:
```powershell
$env:COPILOT_OVERRIDE_OPUS = "claude-opus-4.7-xhigh"
$env:COPILOT_OVERRIDE_HAIKU = "claude-sonnet-4.6"
bun run start
```
Unset values disable the override and restore normal model mapping. The override is read by the proxy process at request time, so restart the proxy if you changed how it is launched.
You can find more options here: [Claude Code settings](https://docs.anthropic.com/en/docs/claude-code/settings#environment-variables)
