Anthropic Claude Sonnet 3.7 Support

[notpeter]

Support for new Anthropic Claude 3.7 release in the Assistant panel.

[ThomAub]

@notpeter do you think the thinking budget can be set from a slash command or from the message in the assistant ?
Happy to help in any way !

[notpeter]

Initial support will be for using it in the assistant.
Subsequent work can be around additional features (budget, etc).

An update: PR #25497 is ready to go with this.
Hotfix releases for stable/preview will likely go out later today which include this.

There is a minor upstream Anthropic issue, specifically API responses from claude3.7 are missing three response headers (anthropic-ratelimit-requests-*). This results in Zed complaining with errors in the Zed.log on every request:

2025-02-24T15:48:33.50199-05:00 [ERROR] missing header `anthropic-ratelimit-requests-limit`
2025-02-24T15:48:33.922569-05:00 [ERROR] Other(Failed to log: 400 Bad Request)

It appears to be harmless and I expect Anthropic will fix this server-side shortly.

In the meantime if you can't wait for the hotfix releases you can add this to your settings and use Claude 3.7 right now:

  "language_models": {
    "anthropic": {
      "version": "1",
      "available_models": [
        {
          "name": "claude-3-7-sonnet-latest",
          "max_tokens": 200000,
          "display_name": "Claude 3.7 Early Bird"
        }
      ]
    }
  },

This shipped last night in Zed Preview v0.175.4-pre and Zed Stable v0.174.7.

Anthropic fixed the upstream issue and is now including the expected headers.
