Models

Within AgentKit, models are adapters that wrap a given provider (ex. OpenAI, Anthropic)‘s specific model version (ex. gpt-3.5).

Each Agent can each select their own model to use and a Network can select a default model.

import { openai, anthropic, gemini } from "@inngest/agent-kit";

​

How to use a model

​

Create a model instance

import { openai, createAgent } from "@inngest/agent-kit";


const model = openai({ model: "gpt-3.5-turbo" });
const modelWithApiKey = openai({ model: "gpt-3.5-turbo", apiKey: "sk-..." });

​

Configure model hyper parameters (temperature, etc.)

You can configure the model hyper parameters (temperature, etc.) by passing the defaultParameters option:

import { openai, createAgent } from "@inngest/agent-kit";

const model = openai({
  model: "gpt-3.5-turbo",
  defaultParameters: { temperature: 0.5 },
});

​

Providing a model instance to an Agent

import { createAgent } from "@inngest/agent-kit";

const supportAgent = createAgent({
  model: openai({ model: "gpt-3.5-turbo" }),
  name: "Customer support specialist",
  system: "You are an customer support specialist...",
  tools: [listChargesTool],
});

​

Providing a model instance to a Network

import { createNetwork } from "@inngest/agent-kit";

const network = createNetwork({
  agents: [supportAgent],
  defaultModel: openai({ model: "gpt-4o" }),
});

​
