It's probably missing anthropic headers. I validated against llama.cpp's anthropic endpoint only. Let me take a look. Thanks for the report.

Please try the builds here and tell me if it fixes it: https://github.com/janhq/jan/actions/runs/29387481435?pr=8433

(note: these are nightly builds with API keys stored in OS secret store, report any issues)

[SetSS]

unfortunately still not working

1 & 2 - key check fails
3 & 4 - Model list not received

Should work now.

Anthropic doesn't like requests from a browser (Jan is a webapp) so they were rejecting it with 401 errors. It needed anthropic-dangerous-direct-browser-access: true header.

[SetSS]

yes, it is working now, thank you for your help.
Work with custom server URL and Anthropic URL also

testing on 0.8.3-4588
