Before you connect#
AI access requires sign-in, one confirmed top-up of at least USD 100, an authorized API key and enough available credit for the request. Each later top-up also has a USD 100 minimum; smaller remaining balances stay usable when they cover the request. Credit requires transaction verification. Check service status for model availability before sending traffic. Use your own API key without the Bearer prefix in key fields. The base URL already includes /v1. These configurations were checked against official documentation, not tested against a live GPU deployment.
Configuration#
Open Settings > Admin > Connections > Manage OpenAI API Connections > Add Connection. Set URL to https://weightsapi.com/v1, API Key to the service key, and Model IDs (Filter) to Qwen/Qwen3-32B if manual selection or an allowlist is needed. Save and choose that model. Keep API Type at Chat Completions for this endpoint. An empty filter normally discovers /models.

Optional environment configuration: OPENAI_API_BASE_URL, OPENAI_API_KEY; for multiple connections OPENAI_API_BASE_URLS, OPENAI_API_KEYS are semicolon-separated. OPENAI_API_CONFIGS can set model_ids per connection. Source: Environment configuration.
Verify the connection#
Fetch the model list, then send one short message. A successful model list does not prove tools, vision or JSON schema support. Check the selected deployment’s capabilities before enabling them.
