# Overview

> Configure your AI model for Strix

Strix uses [LiteLLM](https://docs.litellm.ai/docs/providers) for model compatibility, supporting 100+ LLM providers.

## Configuration

Set your model and API key:

| Model             | Provider      | Configuration                    |
| ----------------- | ------------- | -------------------------------- |
| GPT-5.4           | OpenAI        | `openai/gpt-5.4`                 |
| Claude Sonnet 4.6 | Anthropic     | `anthropic/claude-sonnet-4-6`    |
| Gemini 3 Pro      | Google Vertex | `vertex_ai/gemini-3-pro-preview` |

```bash theme={null}
export STRIX_LLM="openai/gpt-5.4"
export LLM_API_KEY="your-api-key"
```

## Local Models

Run models locally with [Ollama](https://ollama.com), [LM Studio](https://lmstudio.ai), or any OpenAI-compatible server:

```bash theme={null}
export STRIX_LLM="ollama/llama4"
export LLM_API_BASE="http://localhost:11434"
```

See the [Local Models guide](/llm-providers/local) for setup instructions and recommended models.
