AI SDK Providers

AI SDK providers are adapter packages that connect Vercel's AI SDK to specific AI model services. Each provider translates the AI SDK's unified API into the format required by a particular service, letting you switch between models by changing a single import and model name.

How Providers Work

All providers follow the same pattern:

import { providerName } from '@ai-sdk/provider-name';
import { generateText } from 'ai';

const { text } = await generateText({
  model: providerName('model-id'),
  prompt: 'Hello!',
});

Together.ai (@ai-sdk/togetherai)

import { togetherai } from '@ai-sdk/togetherai';
// togetherai('meta-llama/Meta-Llama-3.3-70B-Instruct-Turbo')

Image Generation Providers

Image generation uses experimental_generateImage:

import { experimental_generateImage as generateImage } from 'ai';

Choosing a Provider

• Best general-purpose: OpenAI (GPT-4o) or Anthropic (Claude Sonnet)
• Fastest inference: Groq or Cerebras
• Best open-source models: Fireworks, Together.ai, or Groq
• Search-augmented: Perplexity
• Best image generation: Replicate (FLUX) or OpenAI (DALL-E)
• Enterprise/compliance: Google Vertex AI or Azure OpenAI
