A Go implementation of Vercel's AI SDK [Data Stream Protocol](https://sdk.vercel.ai/docs/ai-sdk-ui/stream-protocol#data-stream-example).

- Supports OpenAI, Google, and Anthropic (with Bedrock support)

- Examples for integrating `useChat`

- Chain tool usage in Go, just like `maxSteps`

```ts

// frontend.tsx

const { messages } = useChat({

    // Points to our Go backend!

    api: "/api/chat",

})

```

```go

// backend.go

// Accept the POST request...

var req *aisdk.Chat

messages, err := aisdk.MessagesToOpenAI(req.Messages)

if err != nil {

    http.Error(w, err.Error(), http.StatusInternalServerError)

    return

}

// Convert the http.ResponseWriter to a Data Stream.

dataStream := aisdk.NewDataStream(w)

stream := openaiClient.Chat.Completions.NewStreaming(...)

aisdk.PipeOpenAIToDataStream(stream, dataStream)

```

## Development

Run tests with `go test`. Start the `useChat` demo with:

```bash

# any or all of these can be set

export OPENAI_API_KEY=

export ANTHROPIC_API_KEY=

export GOOGLE_API_KEY=

cd demo

bun i

bun dev

```
