Vercel AI SDK Knowledge Patch Skill

Vercel AI SDK Knowledge Patch

Claude Opus 4.6 knows AI SDK through 3.x. It is unaware of the features below, which cover AI SDK 4.0 (2024-11-18) through 4.1 (2025-01-20).

Index

| Topic | Reference | Key features | |---|---|---| | 4.0 & 4.1 features | references/ai-sdk-4-features.md | PDF files, computer use tools, continuation, image generation, stream smoothing, createDataStreamResponse, tool context/repair, structured outputs with tools, new providers |

PDF Support (4.0)

Send PDFs as file type in message content:

const result = await generateText({
  model: anthropic('claude-3-5-sonnet-20241022'),
  messages: [{
    role: 'user',
    content: [
      { type: 'text', text: 'Summarize this.' },
      { type: 'file', data: fs.readFileSync('./doc.pdf'), mimeType: 'application/pdf' },
    ],
  }],
});

Works with Anthropic, Google Generative AI, and Vertex AI.

Computer Use (4.0)

Anthropic tools accessible via anthropic.tools:

const computerTool = anthropic.tools.computer_20241022({
  displayWidthPx: 1920, displayHeightPx: 1080,
  execute: async ({ action, coordinate, text }) => { /* implement actions */ },
  experimental_toToolResultContent: (result) => /* format result */,
});

await generateText({
  model: anthropic('claude-3-5-sonnet-20241022'),
  tools: { computer: computerTool },
  maxSteps: 10,
});

Also: anthropic.tools.textEditor_20241022(), anthropic.tools.bash_20241022().

Continuation (4.0)

Auto-continue when generation hits length limit:

await generateText({
  model: openai('gpt-4o'),
  maxSteps: 5,
  experimental_continueSteps: true,
  prompt: 'Write a long essay...',
});

Image Generation (4.1)

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

const { image } = await generateImage({
  model: replicate.image('black-forest-labs/flux-1.1-pro-ultra'),
  prompt: 'A cityscape at sunset',
  size: '16:9',
  n: 3,
});
// image.base64, image.uint8Array

Providers: replicate.image(), openai.image(), vertex.image(), fireworks.image().

Stream Smoothing (4.1)

import { smoothStream, streamText } from 'ai';

const result = streamText({
  model, prompt,
  experimental_transform: smoothStream(),
});

Non-blocking Data Streaming (4.1)

Stream custom data before/alongside LLM output:

import { createDataStreamResponse, streamText } from 'ai';

return createDataStreamResponse({
  execute: async (dataStream) => {
    dataStream.writeData({ type: 'source', url: '...' });
    const result = streamText({ model, messages });
    result.mergeIntoDataStream(dataStream);
  },
});

Tool Improvements (4.1)

Execute context: execute(args, { toolCallId, messages, abortSignal }).

Tool call repair:

await generateText({
  model, tools, prompt,
  experimental_repairToolCall: async ({ toolCall, tools, parameterSchema, error }) => {
    if (NoSuchToolError.isInstance(error)) return null;
    const { object } = await generateObject({ model, schema: tools[toolCall.toolName].parameters, prompt: '...' });
    return { ...toolCall, args: JSON.stringify(object) };
  },
});

Structured outputs with tools via experimental_output: Output.object({ schema }) (OpenAI only).
