+# LLM Gateway Provider
+
+This provider enables access to 150+ AI models through [LLM Gateway](https://llmgateway.io), an OpenAI-compatible API gateway that provides unified access to 40+ LLM providers.
+
+## Directory Structure
+
+- **models/**: TOML configuration files for all supported models
+- **provider.toml**: Provider configuration
+- **logo.svg**: Provider logo
+
+## Regenerating Models
+
+Model configurations are generated from the [LLM Gateway repository](https://github.com/theopenco/llmgateway):
+
+```bash
+npx tsx scripts/export-models-dev.ts
+```
+
+## How It Works
+
+LLM Gateway acts as a unified proxy for multiple AI providers. You can access any supported model through a single API endpoint using your LLM Gateway API key.
+
+## Prerequisites
+
+```bash
+export LLMGATEWAY_API_KEY="your-api-key"
+```
+
+## Supported Providers
+
+- OpenAI (GPT-3.5, GPT-4, GPT-4o, GPT-5, o1, o3, o4-mini)
+- Anthropic (Claude 3, 3.5, 3.7, 4, 4.5)
+- Google (Gemini 1.5, 2.0, 2.5, 3, Gemma)
+- Meta (Llama 3.1, 3.3, 4)
+- xAI (Grok 2, 3, 4)
+- DeepSeek (V3, R1)
+- Alibaba (Qwen Max, Plus, Flash, VL, Coder)
+- Mistral (Large, Pixtral, Mixtral)
+- ZAI (GLM 4.5, 4.6, 4.7)
+- ByteDance (Seed, Seedream)
+- Moonshot (Kimi K2)
+- Perplexity (Sonar)
+- And many more...
+
+## Usage with AI SDK
+
+```typescript
+import { createOpenAICompatible } from "@ai-sdk/openai-compatible";
+
+const llmgateway = createOpenAICompatible({
+  baseURL: "https://api.llmgateway.io/v1",
+  apiKey: process.env.LLMGATEWAY_API_KEY,
+});
+
+const result = await generateText({
+  model: llmgateway("claude-sonnet-4-5"),
+  prompt: "Hello!",
+});
+```
