### GitHub Copilot for Xcode 0.50.0
### GitHub Copilot for Xcode 0.51.0

**🚀 Highlights**

- **Reasoning Effort**: Control how deeply reasoning-capable models think before responding. You can now select reasoning efforts directly from the model picker for supported models, letting you balance response speed against answer quality.

- **Bring Your Own Key (BYOK) is now Generally Available**: Bring Your Own Key support has graduated from preview and is now available to all users. Configure your own API keys for third-party models directly in Copilot for Xcode settings.
- **Kimi K3 Support**: Added compatibility with Kimi K3 through an updated Copilot language server.

**💪 Changes**

- Added internal support for upcoming [usage-based billing](https://github.blog/news-insights/company-news/github-copilot-is-moving-to-usage-based-billing/), including billing updates for the usage panel, usage notifications, and model picker. This will be visible once usage-based billing rolls out.

We **strongly recommend** upgrading to this version as soon as possible.
- Added Agent Client Protocol (ACP) plugin metadata for GitHub Copilot, including marketplace discovery and installation configuration.
- Fixed model pricing tooltips so they correctly display token pricing from the latest model metadata.
