Features

Langtrain provides a complete toolkit for the modern AI engineer.

| Feature | Description | | :--- | :--- | | Autonomous Agents | Create, manage, and chat with custom agents. Routable via lt agent. | | Langtune | Fine-tune LLMs (Llama 3, Mistral) locally using QLoRA or dispatch to H100s. | | Langvision | Optimize multimodal datasets and vision models for edge deployment. | | Enterprise Security | Local-first architecture. Your data leaves your machine only when you say so. | | Instant Deploy | Push your verified agents to production endpoints with lt deploy. |

SDK Integration

Use the power of Langtrain directly in your Node.js or TypeScript applications.

import { Langvision, Langtune } from 'langtrain';

// Initialize with your project context
const vision = new Langvision({ apiKey: process.env.LANGTRAIN_API_KEY });
const tune = new Langtune({ apiKey: process.env.LANGTRAIN_API_KEY });

async function main() {
  // 1. Analyze Visual Context
  const analysis = await vision.analyze({
    image: './dashboard.png',
    prompt: 'Extract UI component hierarchy'
  });

  // 2. Generate Optimized Code
  const code = await tune.generate({
    model: 'gpt-4-turbo',
    prompt: `Create a React component based on: ${analysis.description}`
  });
  
  console.log(code);
}

Configuration

Configure your environment seamlessly via CLI or environment variables.

| Variable | Description | | :--- | :--- | | LANGTRAIN_API_KEY | Your project Secret Key (find it in Settings). | | LANGTRAIN_WORKSPACE_ID | (Optional) Target specific workspace environments. |

Pro Tip: Run lt login to authenticate continuously without managing .env files manually.
