LobeChat → AI24X

LobeChat (LobeHub) is a popular open-source chat client. Add AI24X as a custom OpenAI-compatible provider—one key for flash/pro and VIP named models, PayPal USD top-up.

1) Web setup (tested path)

  1. Open lobechat.com (or the desktop app).
  2. Settings → Language models → Add custom provider → choose OpenAI.
  3. Provider id / name: AI24X. Short blurb: Global models · one key · PayPal.
  4. API Key: your AI24X key from Console.
  5. API proxy / base URL: https://api.ai24x.com/v1 — stop at /v1 (do not append /chat/completions).
  6. Use Responses API: OK for text chat. For tools / agent tool-calling, turn it off and use chat/completions.
  7. Fetch model list → enable flash (and pro / ultra if you need them) → Save.
  8. New chat → pick AI24X / flash → send hello.

2) Desktop

Windows / macOS desktop uses the same path: Settings → Language models → custom provider → same fields as above.

3) Pitfalls (field-tested)

  • Proxy set to …/v1/chat/completions → 405 (LobeChat already appends /chat/completions).
  • Responses is live for text chat. For tools / agent tool-calling, turn Responses off and use chat/completions (Completions supports tools).
  • Connectivity check may fail while chat still works (check may use GET; chat uses POST).
  • After rotating a key in Console, update the provider’s API Key field.

4) Quick errors

404/405 → base URL must end at /v1. 401 → new key in Console. 429 → slow down and retry.

Troubleshooting order

  1. Send a plain hello with flash. Chat working tells you the connection is fine even if the connectivity check disagrees — the check may use GET while chat uses POST.
  2. If chat also fails, verify the key with the curl guide from a terminal.
  3. Confirm the base URL stops at /v1.
  4. For tool-calling failures, turn the Responses API off as described above.
  5. After rotating a key, update the provider's API Key field and save again.

Cost habits that pay off

Keep flash as the default for everyday conversations and move a chat to pro only when the answer really needs deeper reasoning. Because every model shares the same key and base URL, changing your default is a settings toggle — no reconfiguration.
