Groq

The Groq adapter provides access to Groq's fast inference API, featuring the world's fastest LLM inference.

Installation

shell

npm install @tanstack/ai-groq

Basic Usage

import { chat } from "@tanstack/ai";
import { groqText } from "@tanstack/ai-groq";

const stream = chat({
  adapter: groqText("llama-3.3-70b-versatile"),
  messages: [{ role: "user", content: "Hello!" }],
});

Basic Usage - Custom API Key

import { chat } from "@tanstack/ai";
import { createGroqText } from "@tanstack/ai-groq";

const adapter = createGroqText("llama-3.3-70b-versatile", process.env.GROQ_API_KEY!, {
  // ... your config options
});

const stream = chat({
  adapter,
  messages: [{ role: "user", content: "Hello!" }],
});

Configuration

import { createGroqText, type GroqTextConfig } from "@tanstack/ai-groq";

const config: Omit<GroqTextConfig, 'apiKey'> = {
  baseURL: "https://api.groq.com/openai/v1", // Optional, for custom endpoints
};

const adapter = createGroqText("llama-3.3-70b-versatile", process.env.GROQ_API_KEY!, config);

Example: Chat Completion

import { chat, toServerSentEventsResponse } from "@tanstack/ai";
import { groqText } from "@tanstack/ai-groq";

export async function POST(request: Request) {
  const { messages } = await request.json();

  const stream = chat({
    adapter: groqText("llama-3.3-70b-versatile"),
    messages,
  });

  return toServerSentEventsResponse(stream);
}

Example: With Tools

import { chat, toolDefinition } from "@tanstack/ai";
import { groqText } from "@tanstack/ai-groq";
import { z } from "zod";

const searchDatabaseDef = toolDefinition({
  name: "search_database",
  description: "Search the database",
  inputSchema: z.object({
    query: z.string(),
  }),
});

const searchDatabase = searchDatabaseDef.server(async ({ query }) => {
  // Search database
  return { results: [] };
});

const messages = [{ role: "user", content: "Search for something" }];

const stream = chat({
  adapter: groqText("llama-3.3-70b-versatile"),
  messages,
  tools: [searchDatabase],
});

Model Options

Groq supports various provider-specific options. Sampling parameters live here too — temperature, top_p, and max_completion_tokens (Groq's token-limit key) — rather than as root-level props on chat():

const stream = chat({
  adapter: groqText("llama-3.3-70b-versatile"),
  messages: [{ role: "user", content: "Hello!" }],
  modelOptions: {
    temperature: 0.7,
    max_completion_tokens: 1024,
    top_p: 0.9,
  },
});

If you previously passed temperature / topP / maxTokens at the root of chat(), see Moving Sampling Options into modelOptions.

Reasoning

Enable reasoning for models that support it (e.g., openai/gpt-oss-120b, qwen/qwen3-32b). This allows the model to show its reasoning process, which is streamed as thinking chunks:

modelOptions: {
  reasoning_effort: "medium", // "none" | "default" | "low" | "medium" | "high"
}

Environment Variables

Set your API key in environment variables:

shell

GROQ_API_KEY=gsk_...

API Reference

groqText(model, config?)

Creates a Groq chat adapter using environment variables.

Parameters:

model - The model name (e.g., llama-3.3-70b-versatile)
config (optional) - Optional configuration object. Supports the same options as createGroqText except apiKey, which is auto-detected from GROQ_API_KEY environment variable. Common options:
- baseURL - Custom base URL for API requests (optional)
  Returns: A Groq chat adapter instance.

createGroqText(model, apiKey, config?)

Creates a Groq chat adapter with an explicit API key.

Parameters:

model - The model name (e.g., llama-3.3-70b-versatile)
apiKey - Your Groq API key
config (optional) - Optional configuration object:
- baseURL - Custom base URL for API requests (optional)
  Returns: A Groq chat adapter instance.

Limitations

Text-to-Speech: Groq does not currently expose a TTS adapter. Use OpenAI, Gemini, ElevenLabs, or fal for speech generation.
Image Generation: Groq does not support image generation. Use OpenAI, Gemini, or fal for image generation.
Transcription: Groq does not currently expose a transcription adapter through TanStack AI.
