# How to use AI SDK with Subconscious

> To use the AI SDK with Subconscious, create a provider with `createOpenAICompatible` from `@ai-sdk/openai-compatible`, setting `baseURL` to `https://api.subconscious.dev/v1`, then pass `subconscious("subconscious/glm-5.3-marathon")` to `generateText` or `streamText`. The same provider works in eve and Mastra.

## Before you start

- Node.js 20+
- A Subconscious account and API key

## Set up AI SDK

### 1. Install AI SDK

Install the framework and its OpenAI-compatible client.

```bash
pnpm add ai @ai-sdk/openai-compatible
```

### 2. Create a Subconscious API key

Sign in at https://platform.subconscious.dev, create an API key, and export it so the tool can read it.

```bash
export SUBCONSCIOUS_API_KEY="your_key"
```

### 3. Point it at Subconscious

includeUsage reports token usage on streamed responses.

```ts
import { createOpenAICompatible } from "@ai-sdk/openai-compatible";
import { generateText } from "ai";

const subconscious = createOpenAICompatible({
  name: "subconscious",
  apiKey: process.env.SUBCONSCIOUS_API_KEY,
  baseURL: "https://api.subconscious.dev/v1",
  includeUsage: true,
});

const { text } = await generateText({
  model: subconscious("subconscious/glm-5.3-marathon"),
  prompt: "Write a haiku about durable agents.",
});
console.log(text);
```

### 4. Run it

Run it with any TypeScript runner.

```bash
npx tsx index.ts
```

## Frequently asked questions

### Which Subconscious model should I use with AI SDK?

Start with subconscious/glm-5.3-marathon, an open frontier coding model built for long agent runs. subconscious/deepseek-v4.1-flash-marathon is a cheaper, high-throughput alternative that also takes image input. Use the full model ID, including the subconscious/ prefix.

### Is AI SDK on Subconscious OpenAI- or Anthropic-compatible?

This guide connects AI SDK through the OpenAI-compatible Subconscious API. Subconscious serves both formats: OpenAI Chat Completions at https://api.subconscious.dev/v1 and Anthropic Messages at https://api.subconscious.dev.

### How is AI SDK usage on Subconscious billed?

Per token by default, with no commitment. Heavy users can switch to a monthly token plan: a fixed price for a large daily token allowance shared across your team.
