OpenAI compatible ProvidersPerplexity
Perplexity Provider
Perplexity is a search engine that uses LLMs to answer questions. It offers an OpenAI compatible API that you can use with the AI SDK.
Setup
The Perplexity provider is available via the @ai-sdk/openai
module as it is compatible with the OpenAI API.
You can install it with
pnpm add @ai-sdk/openai
Provider Instance
To use Perplexity, you can create a custom provider instance with the createOpenAI
function from @ai-sdk/openai
:
import { createOpenAI } from '@ai-sdk/openai';
const perplexity = createOpenAI({ name: 'perplexity', apiKey: process.env.PERPLEXITY_API_KEY ?? '', baseURL: 'https://api.perplexity.ai/',});
Language Models
You can create Perplexity models using a provider instance.
The first argument is the model id, e.g. llama-3-sonar-large-32k-online
.
const model = perplexity('llama-3-sonar-large-32k-online');
Example
You can use Perplexity language models to generate text with the generateText
function:
import { createOpenAI } from '@ai-sdk/openai';import { generateText } from 'ai';
const perplexity = createOpenAI({ name: 'perplexity', apiKey: process.env.PERPLEXITY_API_KEY ?? '', baseURL: 'https://api.perplexity.ai/',});
const { text } = await generateText({ model: perplexity('llama-3-sonar-large-32k-online'), prompt: 'Write a vegetarian lasagna recipe for 4 people.',});
Perplexity language models can also be used in the streamText
function.
