Describe the feature

With the release of Claude 3 Opus, it advertises the best coding assistant performance available today. Would be nice to be able to use different APIs with Zed

Just playing with the free model it's very impressive

[jaanli]

Major +1 on this, would help switch from VS code :)

[liam-k]

Yes please! although I would probably rename this issue to "make custom assistant APIs possible". Because who knows what the next best LLM will be?

[elamien]

YES claude 3 opus has been unmatched in terms of context length!

[lessless]

I'm not going back to ChatGPT anytime soon, so Claude support is very desired feature

[noozo]

+1

[windhorn]

I'm looking forward to Claude3's support!

Here's the best that's available now of how I'm coping: https://colab.research.google.com/github/jaanli/language-model-notebooks/blob/main/notebooks/getting-started.ipynb

Claude is available in Zed v0.136.0-pre.

[jaanli]

Yay! Thanks so much @JosephTLyons !!!

@as-cii - is there more documentation or a way to check whether Claude or GPT4o is set?

I can't figure out the way to add the ANTHROPIC_API_KEY command line variable.

Has anyone gotten Claude working in Zed with their API key?

[rafaelbiten]

Same here. I've been trying to set an open API key to work with GPT4o within Zed and I can't get it work. It keeps saying: Failed to connect to OpenAI API: The model 'gpt-4o' does not exist or you do not have access to it.

Hey @jaanli, you should be able to set it in your shell rc file or by launching zed via the command line:

ANTHROPIC_API_KEY=xyz zed /path/to/project

Make sure you set this in your settings.json:

"assistant": {
    "version": "1",
    "provider": {
      "name": "anthropic"
    }
  }

@rafaelbiten: it seems like you're misspelling gpt-4o (0 vs o)?

[rafaelbiten]

Sorry, I just misspelled that in my initial message. Do I have to setup the assistant in the settings.json file? I tried resetting the key a few times. Also, just want to confirm one thing. The instructions say:

Make sure your OpenAI account has credits.

Is that the case if we're subscribed to ChatGPT Plus? If it is, then that's my problem...

Ok so just for anyone else that needs a reference of how to do this. You dont need to add the ANTHROPIC_API_KEY and launch it via the command line.

you can just add these assistant settings as @as-cii says

"assistant": {
    "version": "1",
    "provider": {
      "name": "anthropic"
    }
  }

Then when you save the settings (cmd+s) the assistant panel will pop open and ask you to add your API key. Which you need to get from here https://console.anthropic.com/settings/keys

Even if you pay for Claude pro, you will still have to pay for additional credits to use it via the API. Which you can do here https://console.anthropic.com/settings/plans

This confused the hell out of me. So hopefully someone else finds this comment useful.

I've added the above instructions to the documentation https://github.com/zed-industries/zed/pull/13765
