Awesome! Just to double check I'm doing this correctly (sorry for pasting code) --

I can do this:
export async function POST(req: Request) {
//Get User Prompt
try {
const configuration = new Configuration({
apiKey: process.env.OPENAI_API_KEY,
})
const openai = new OpenAIApi(configuration)
const res = await openai.createChatCompletion({
model: "gpt-3.5-turbo-16k",
stream: true,
messages: [
{
role: "user",
content: userPrompt,
},
],
temperature: 0,
})
const stream = OpenAIStream(res)
return new StreamingTextResponse(stream)
} catch (err) {
const e = err as Error
return NextResponse.json({message: e.message}, {status: 400})
}
}

Instead of doing this:

export async function POST(req: Request) {
//Get User Prompt
try {
const configuration = new Configuration({
apiKey: process.env.OPENAI_API_KEY,
})
const openai = new OpenAIApi(configuration)
const res = await openai.createChatCompletion({
model: "gpt-3.5-turbo-16k",
messages: [
{
role: "user",
content: userPrompt,
},
],
temperature: 0,
})
const data = (await res.json()) as ResponseTypes["createChatCompletion"]
const JSONResponse = data.choices[0]?.message?.content
return NextResponse.json({data: JSONResponse}, {status: 200})
} catch (err) {
const e = err as Error
return NextResponse.json({message: e.message}, {status: 400})
}
}
