Together AI

Together is a cloud platform providing fast, cost-effective inference for 200+ open-source models plus fine-tuning and training capabilities.

Why Vibe Coders Use It

• Widest model selection — 200+ open-source models (Llama, DeepSeek, Mixtral, FLUX, Stable Diffusion)
• Competitive pricing — among the cheapest for open-source model inference
• Image generation — FLUX, Stable Diffusion, and other image models
• Fine-tuning — customize open models with your data
• Batch processing — cost-effective for high-volume, non-real-time tasks

Key Specs

Getting Started

1. Sign Up for Together AI

Visit together.ai and create an account.

2. Get an API Key

Generate an API key from your Together dashboard.

3. Install the AI SDK Provider

npm install @ai-sdk/togetherai

4. Quick Chat Example

import { togetherai } from '@ai-sdk/togetherai';
import { generateText } from 'ai';

const { text } = await generateText({
  model: togetherai('meta-llama/Meta-Llama-3.3-70B-Instruct-Turbo'),
  prompt: 'Write a function to detect duplicate items in an array',
});

console.log(text);

5. Cost-Effective Batch Processing

import { togetherai } from '@ai-sdk/togetherai';

// Process many prompts in batch for lower cost
const prompts = [
  'Explain closures in JavaScript',
  'What is React Server Components?',
  'How does SQL indexing work?',
];

const results = await Promise.all(
  prompts.map((prompt) =>
    togetherai.generateText({
      model: togetherai('meta-llama/Meta-Llama-3.3-70B-Instruct-Turbo'),
      prompt,
    })
  )
);

console.log(results);

6. Image Generation with FLUX

import { togetherai } from '@ai-sdk/togetherai';
import { experimental_generateImage as generateImage } from 'ai';

const { image } = await generateImage({
  model: togetherai.image('black-forest-labs/FLUX.1-pro'),
  prompt: 'A modern dashboard UI with data visualization charts',
});

console.log(image.url);

7. Fine-Tuning a Model

// Upload your training data
const finetuneJob = await fetch(
  'https://api.together.xyz/v1/fine-tune',
  {
    method: 'POST',
    headers: {
      Authorization: `Bearer ${TOGETHER_API_KEY}`,
      'Content-Type': 'application/json',
    },
    body: JSON.stringify({
      training_file: 'file_id_from_upload',
      model: 'meta-llama/Meta-Llama-3.3-70B-Instruct-Turbo',
      n_epochs: 3,
    }),
  }
).then((r) => r.json());

// Your fine-tuned model ready in hours

8. Streaming Chat

import { togetherai } from '@ai-sdk/togetherai';
import { streamText } from 'ai';

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

  const result = streamText({
    model: togetherai('meta-llama/Meta-Llama-3.3-70B-Instruct-Turbo'),
    messages,
  });

  return result.toDataStreamResponse();
}

When to Use Together vs. Alternatives

Use Together when you need the cheapest access to open models or want to fine-tune at scale. Use Groq if latency is critical. Use Claude or GPT for the strongest proprietary reasoning.

Popular Models

• Llama 3.3 70B — Strong general-purpose
• DeepSeek-V3 — Excellent reasoning
• Qwen 2.5 72B — High-quality reasoning
• FLUX 1.1 Pro — Best open-source image generation
