+title: Custom inference endpoint
+description: >-
+  Connect Warp to any OpenAI-compatible custom inference endpoint, such as
+  OpenRouter, LiteLLM, z.ai, or an internal gateway. Available on the Free
+  plan and all eligible paid plans.
+---
+
+A **Custom inference endpoint (CIE)** lets you connect Warp's agents to any OpenAI-compatible inference endpoint, so you can route AI requests through your preferred model router, hosted gateway, or internal infrastructure.
+
+CIE is the right fit when you want to choose your provider, consolidate billing through a third-party router, or run inference behind your own gateway — without giving up the agent experience inside Warp. When a CIE is configured and selected, Warp **never consumes your** [credits](/support-and-community/plans-and-billing/credits/) for the request.
+
+:::note
+CIE is available on the Free plan and on all eligible paid plans. See [warp.dev/pricing](https://www.warp.dev/pricing) for the current list of eligible plans.
+:::
+
+## Key features
+
+* **OpenAI-compatible** - Works with any endpoint that implements the OpenAI Chat Completions API.
+* **Provider flexibility** - Use a model router (OpenRouter, LiteLLM), a model provider with an OpenAI-compatible surface (z.ai), or your own internal gateway.
+* **No Warp credits consumed** - Inference is billed directly by your endpoint provider; Warp's metered features remain unaffected.
+* **Local configuration** - Endpoint URLs and credentials are stored locally on your device and never synced to the cloud.
+
+## How it works
+
+CIE expects your endpoint to implement the **OpenAI Chat Completions API** (`POST /v1/chat/completions`). Any service that exposes a compatible surface can be used as a CIE target:
+
+* **OpenRouter** - Aggregates many model providers behind a single OpenAI-compatible API and consolidated billing.
+* **LiteLLM** - A self-hosted proxy that exposes a unified, OpenAI-compatible API across providers.
+* **z.ai** - A model provider with an OpenAI-compatible API surface for its models.
+* **Internal gateways** - Any in-house service that fronts model providers behind an OpenAI-compatible endpoint (for example, a corporate AI gateway with logging, redaction, or access control).
+
+When you configure a CIE, Warp stores the endpoint URL, model identifiers, and credentials **locally on your device**. They are never synced to Warp's servers.
+
+:::caution
+CIE does not apply to [Oz Cloud Agents](/agent-platform/cloud-agents/overview/). Because CIE configuration is stored locally, it is not available to cloud-hosted agent runs. Cloud agent runs always consume [Warp credits](/support-and-community/plans-and-billing/credits/).
+:::
+
+When a CIE-routed model is selected:
+
+* Warp **does not consume** any of your [credits](/support-and-community/plans-and-billing/credits/).
+* Costs are billed directly by your endpoint provider.
+* Warp does not retain or store your endpoint credentials on any of its servers.
+
+## Enabling a custom inference endpoint
+
+To enable and configure a custom inference endpoint:
+
+1. In Warp, open **Settings** and search for `custom inference endpoint` to jump to the configuration.
+2. Add your endpoint URL (the base URL that exposes `/v1/chat/completions`) and any required credentials (typically an API key).
+3. Specify the model identifier(s) you want to route through this endpoint.
+4. Save the configuration. Once added, you'll see your custom models appear in the model picker.
+
+When you explicitly select a CIE-routed model from the model picker, Warp routes the request through your endpoint instead of consuming Warp's credits.
+
+The CIE configuration flow mirrors the [Bring your own API key](/support-and-community/plans-and-billing/bring-your-own-api-key/) setup, so the steps will feel familiar if you've already configured BYOK.
+
+## Billing behavior
+
+### Warp credits
+
+When you select a CIE-routed model from the model picker:
+
+* No Warp credits are consumed for that request.
+* Inference is billed directly by your endpoint provider, according to their pricing.
+* The credit transparency footer will show "0 credits used" for CIE-routed requests.
+
+### Auto routing still uses Warp credits
+
+Warp's **Auto** models dynamically route across providers using Warp's infrastructure. Because Auto routing depends on Warp, **Auto always consumes Warp's credits**, even if you've configured a custom inference endpoint.
+
+To use your endpoint, select the specific CIE-backed model from the model picker rather than an Auto option.
+
+### Other AI features in Warp
+
+Some AI-powered features rely on Warp's infrastructure and are unaffected by CIE configuration. These continue to consume credits according to your plan; see [Credits](/support-and-community/plans-and-billing/credits/) for details.
+
+## Zero Data Retention (ZDR)
+
+Warp is **SOC 2 compliant** and has **Zero Data Retention (ZDR)** agreements with all of its contracted LLM providers.
+
+When you use a custom inference endpoint:
+
+* Data retention is determined by **your endpoint provider** and any upstream model providers they route to.
+* Warp **cannot enforce ZDR** for requests sent through a custom inference endpoint.
+* If your endpoint provider does not have ZDR with the underlying model provider, your requests may be retained according to their terms.
+
+Review your endpoint provider's data handling and retention policies before routing sensitive prompts through a CIE.
+
+## Plan availability
+
+CIE is available on the Free plan and on all eligible paid plans. See [warp.dev/pricing](https://www.warp.dev/pricing) for the current list of eligible plans and any plan-specific limits.
+
+Centrally configured, admin-managed CIE for teams is not yet available. Each user configures their own endpoint locally. Enterprise teams that need centrally managed model routing today should see [Bring your own LLM](/enterprise/enterprise-features/bring-your-own-llm/).
