190proof

A unified interface for interacting with multiple AI providers including OpenAI, Anthropic, Google, Groq, and AWS Bedrock. This package provides a consistent API for making requests to different LLM providers while handling retries, streaming, and multimodal inputs.

Features

Fully-local unified interface across multiple AI providers that includes:

• 🛠️ Consistent function/tool calling across all providers
• 💬 Consistent message alternation & system instructions
• 🖼️ Image format & size normalization
• 🔄 Automatic retries with configurable attempts
• 📡 Streaming by default
• ☁️ Cloud service providers supported (Azure, AWS Bedrock)

Installation

npm install 190proof

Usage

Basic Example

import { callWithRetries } from "190proof";
import { GPTModel, GenericPayload } from "190proof/interfaces";

const payload: GenericPayload = {
  model: GPTModel.GPT4O_MINI,
  messages: [
    {
      role: "user",
      content: "Tell me a joke.",
    },
  ],
};

const response = await callWithRetries("my-request-id", payload);
console.log(response.content);

Using Different Providers

import { callWithRetries } from "190proof";
import {
  ClaudeModel,
  GeminiModel,
  GroqModel,
  GenericPayload,
} from "190proof/interfaces";

// Anthropic
const claudePayload: GenericPayload = {
  model: ClaudeModel.SONNET_4,
  messages: [{ role: "user", content: "Hello!" }],
};

// Google
const geminiPayload: GenericPayload = {
  model: GeminiModel.GEMINI_2_0_FLASH,
  messages: [{ role: "user", content: "Hello!" }],
};

// Groq
const groqPayload: GenericPayload = {
  model: GroqModel.LLAMA_3_70B_8192,
  messages: [{ role: "user", content: "Hello!" }],
};

const response = await callWithRetries("request-id", claudePayload);

With Function Calling

const payload: GenericPayload = {
  model: GPTModel.GPT4O,
  messages: [
    {
      role: "user",
      content: "What is the capital of France?",
    },
  ],
  functions: [
    {
      name: "get_country_capital",
      description: "Get the capital of a given country",
      parameters: {
        type: "object",
        properties: {
          country_name: {
            type: "string",
            description: "The name of the country",
          },
        },
        required: ["country_name"],
      },
    },
  ],
};

const response = await callWithRetries("function-call-example", payload);
// response.function_call contains { name: string, arguments: Record<string, any> }

With Images

const payload: GenericPayload = {
  model: ClaudeModel.SONNET_4,
  messages: [
    {
      role: "user",
      content: "What's in this image?",
      files: [
        {
          mimeType: "image/jpeg",
          url: "https://example.com/image.jpg",
        },
      ],
    },
  ],
};

const response = await callWithRetries("image-example", payload);

With System Messages

const payload: GenericPayload = {
  model: GeminiModel.GEMINI_2_0_FLASH,
  messages: [
    {
      role: "system",
      content: "You are a helpful assistant that speaks in a friendly tone.",
    },
    {
      role: "user",
      content: "Tell me about yourself.",
    },
  ],
};

const response = await callWithRetries("system-message-example", payload);
