Zed v1.12.1 is a small but helpful update, especially if you use Zed's built-in AI assistant. It connects the editor to a newly released, highly capable AI model and cleans up a minor visual annoyance when reading code documentation.
What's new
- Claude Opus 5 support: You can now use Anthropic's new Claude Opus 5 AI model right inside Zed. This works if you use Anthropic directly, or if you use Amazon Bedrock with "BYOK" (Bring Your Own Key—a setup where you plug in your own paid AI account credentials instead of relying on Zed's servers).
Fixes
- Hover documentation spacing: We squashed a bug where "hover documentation" (the helpful text box that pops up when you pause your mouse over a piece of code) was showing way too many line breaks. It should now be much easier to read without giant, distracting gaps.
