Code example

import Anthropic from '@anthropic-ai/sdk';
import { AnthropicStream, StreamingTextResponse } from 'ai';
import { experimental_buildAnthropicPrompt } from 'ai/prompts';

// Create an Anthropic API client (that's edge friendly??)
const anthropic = new Anthropic({
apiKey: process.env.ANTHROPIC_API_KEY || '',
});

// IMPORTANT! Set the runtime to edge
export const runtime = 'edge';

export async function POST(req: Request) {
// Extract the prompt from the body of the request
const { messages } = await req.json();

// Ask Claude for a streaming chat completion given the prompt
const response = await anthropic.completions.create({
prompt: experimental_buildAnthropicPrompt(messages),
model: 'claude-2',
stream: true,
max_tokens_to_sample: 300,
});
// Convert the response into a friendly text-stream
const stream = AnthropicStream(response);
// Respond with the stream
return new StreamingTextResponse(stream);
}

What is the version of your anthropic SDK? (the docs are for v0.15.0 and newer)

[bcholewa]

"@anthropic-ai/sdk": "^0.17.1"

[GoldinGuy]

also experiencing this issue with "^0.17.1"

[Gitnock]

v0.15.0 is what's working for me

[GoldinGuy]

I'm still experiencing this issue using v0.15.0. what is the version of ai you're using?

[Gitnock]

I'm still experiencing this issue using v0.15.0. what is the version of ai you're using?
am using ai@3.1.0-canary.1

[GoldinGuy]

can confirm ai@3.1.0-canary.1 and v0.15.0 for the anthropic SDK fixes this issue. hopefully this is addressed in the next version of ai.

I just tried to reproduce with v0.18.0 of the anthropic SDK and the build passed for me. Is this still an issue with that version?

[bcholewa]

"@anthropic-ai/sdk": "^0.18.0" & "ai": "^3.0.12" - it all works now.
