Our Pipelines sister-project already supports many providers that are often requested, including Anthropic:
https://github.com/open-webui/pipelines/tree/main/examples/pipelines/providers

The process for actually setting this up is very unclear and unwieldly. For anyone else that doesn't want to lose the time I lost:

1. Set up the main Open-WebUI Docker container following repo instructions (there goes half your RAM)
2. Set up Pipelines Docker container following the instructions in the readme (there goes the other half of your RAM)
3. In Open-WebUI click your Profile Picture > Admin Panel > Gear Icon (Admin Settings) > Pipelines > Paste this URL: https://github.com/open-webui/pipelines/blob/main/examples/pipelines/providers/anthropic_manifold_pipeline.py
4. Enter your Anthropic API key.

Docs PRs always welcomed 👍

Thanks to @justinh-rahb for the pipelines project (though it feels overkill making this a whole separate service). Thanks @zaptrem for the extra guidance.

I had all this working for a while, but then it just broke ... containers all seem fine but I'm getting random errors like:

• Uh-oh! There was an issue connecting to anthropic/claude-3.5-sonnet. Load failed
• OpenAI: Could not fetch models from OpenAI, please update the API key in the valves.

What are Valves? No idea. Will keep playing and trying to make this work ...

You can now integrate anthropic manifold through functions without installing Pipelines : https://openwebui.com/f/justinrahb/anthropic/

Works well for me.

Fantastic, that is exactly what I'd asked for in the original post. Confirmed it works great!

Full install instructions:

1. Go to https://openwebui.com/f/justinrahb/anthropic/
2. Press Get and specify your OpenWebUI URL to install the script into your Workspace as a Function.
3. Once installed, click the setting icon (called Valves for some reason) and enter your Anthropic key.
4. Enjoy Claude working perfectly without an entire new Pipelines docker image needed.

Glad that I could be of assistance 🫡

Thank you, everyone! Amazing. The function works really well.

Is anyone else encountering a network error 400 stating you have insufficient credit balance? I thought Claude 3.5-sonnet was free use.

Their chat app at claude.ai has a limited free tier, the API does not.
