vercelAI(options)

A low-level provider adapter that wraps any Vercel AI SDK LanguageModel as an AIProvider. All the built-in provider shortcuts (openai(), anthropic(), google(), xai()) are thin wrappers around this function.

Use vercelAI() directly when you need a provider that doesn't have a dedicated shortcut yet — Mistral, Cohere, Groq, AWS Bedrock, and dozens more are all supported.

Signature

function vercelAI(options: VercelAIOptions): AIProvider

Options

interface VercelAIOptions {
  /**
   * A Vercel AI SDK LanguageModel instance.
   * The model is fixed here — ChatRequest.model is ignored.
   */
  model: LanguageModel;
}

Installation

npm install @daedalus-ai-dev/ai-sdk ai
# Plus whichever @ai-sdk/* provider package you need
npm install @ai-sdk/mistral

Examples

Mistral

import { agent, configure, vercelAI } from '@daedalus-ai-dev/ai-sdk';
import { mistral } from '@ai-sdk/mistral';

configure({ provider: vercelAI({ model: mistral('mistral-large-latest') }) });

Groq

import { createGroq } from '@ai-sdk/groq';
import { vercelAI } from '@daedalus-ai-dev/ai-sdk';

const groq = createGroq({ apiKey: process.env.GROQ_API_KEY });

configure({ provider: vercelAI({ model: groq('llama-3.3-70b-versatile') }) });

AWS Bedrock

import { bedrock } from '@ai-sdk/amazon-bedrock';
import { vercelAI } from '@daedalus-ai-dev/ai-sdk';

configure({ provider: vercelAI({ model: bedrock('anthropic.claude-3-5-sonnet-20241022-v2:0') }) });

Ollama (local models)

import { ollama } from 'ollama-ai-provider';
import { vercelAI } from '@daedalus-ai-dev/ai-sdk';

configure({ provider: vercelAI({ model: ollama('llama3.2') }) });

Notes

• Model is fixed — the model string inside ChatRequest is ignored; the model you pass in VercelAIOptions is always used. This is by design: the Vercel AI SDK embeds the model in the LanguageModel object.
• Streaming uses streamText() and maps Vercel AI SDK v6 stream events (tool-input-start/delta/end, finish-step) to the SDK's StreamChunk format.
• Structured output (schema option on agent()) is not yet supported through this adapter; use the openrouter() provider for structured output.
