OpenAI-compatible providers

​

Overview

Admins can add any OpenAI-compatible endpoint as a custom provider: self-hosted servers such as vLLM, an internal AI gateway, or a provider Wirebase doesn’t list.

​

Endpoint requirements

• Implements POST /chat/completions in the OpenAI format, including streaming (stream: true) with server-sent events.
• Reachable from the public internet over HTTPS.
• Accepts the API key as Authorization: Bearer <key>, or needs no key. Add any other headers your gateway needs under Custom Headers.
• Supports function calling (tools) if you want members to use tools, agents, workflows and connectors with these models.

​

Configure

Enter the base URL, for example https://llm.internal.example.com/v1. Wirebase appends /chat/completions; if you paste the full path, it’s normalized. Then list the model IDs your endpoint serves, exactly as the endpoint expects them, and enable them in Admin → Models.

​

Pricing

Custom models have no list price, so their spend shows as under-reported in reporting. Set input and output prices per 1M tokens in Admin → Models to include them in spend and usage limits.
