 | `proxy` | HTTP(S) proxy URL for all outbound CLI requests (e.g., `http://proxy.example.com:8080`) (v1.0.64+) |
 | `sessionLimits` | Restrict credit or turn usage for a session; limits apply across the current conversation and reset on `/clear` (v1.0.66+) |
 | `stayInAutopilot` | Keep the CLI in autopilot mode after an autopilot task completes, instead of returning to interactive mode (v1.0.69+) |
+| `defaultMode` | Startup mode for new interactive sessions (e.g., `interactive`, `autopilot`, `plan`) (v1.0.81+) |
+| `defaultPermissionMode` | Default approval behaviour for new interactive sessions, independent from `defaultMode` (v1.0.81+) |

+> **Session restore after a crash (v1.0.81+)**: If the CLI is interrupted unexpectedly — a crash or a machine restart — startup now offers to restore any sessions that were still open, so you don't have to reopen each terminal by hand.

+> **Piping an auth token (v1.0.81+)**: Use `copilot login --with-token` to read an authentication token from stdin instead of going through the interactive browser or device-code flow — useful for scripted or containerized setups where a token is already available in the environment.

 In addition to the main config file, GitHub Copilot CLI reads two optional per-project files for repository-specific overrides:

 **Auto mode and server-side model routing** (v1.0.43+): When you select **Auto** as your model, the CLI uses server-side model routing for real-time model selection. Instead of locking in a single model at session start, Auto mode evaluates each request and routes it to the most appropriate model dynamically. This means straightforward questions can be handled by a faster model while complex reasoning tasks are automatically escalated — without you needing to switch models manually.
 
-**Model family aliases** (v1.0.64+): Instead of typing a full model name, you can use short family aliases in the model setting: `opus`, `sonnet`, `haiku` (Anthropic), and `gpt`, `gemini` (Google/OpenAI). The CLI resolves the alias to the latest available model in that family. This is especially useful in scripts or configuration files where you want to track the best model in a family without hardcoding a version string. Recent models available include **Claude Opus 5** (v1.0.75+), the latest in Anthropic's Opus family for the most demanding tasks, and **Grok 4.5** (v1.0.76+) from xAI.

 **Plan mode model** *(v1.0.74+)*: When using plan mode (which blocks file mutations and keeps changes in a planning phase), you can assign a *separate* model specifically for planning — different from your regular session model. This lets you use a fast, cost-effective model for plan drafting while keeping a more capable model on standby for the implementation phase:
