> A unified response parser and SDK generator for LLM APIs across multiple programming languages

LLM-Forge provides a production-ready, type-safe way to parse and normalize responses from multiple LLM providers (OpenAI, Anthropic, Cohere, Google AI, Mistral, and more) with support for generating client libraries in 6 languages: **TypeScript**, **Python**, **Rust**, **Go**, **Java**, and **C#**.

## ✨ Features

## 🚀 Quick Start

### Installation

```bash
npm install @llm-dev-ops/llm-forge
```

### Basic Usage - Response Parsing

```typescript
import { parseResponse } from '@llm-dev-ops/llm-forge';

// Parse any LLM provider response
const response = await fetch('https://api.openai.com/v1/chat/completions', {
  method: 'POST',
  headers: { 'Authorization': `Bearer ${apiKey}` },
  body: JSON.stringify({
    model: 'gpt-4',
    messages: [{ role: 'user', content: 'Hello!' }]
  })
});

const data = await response.json();
const parsed = await parseResponse(data);

if (parsed.success) {
  console.log(parsed.response.messages[0].content);
  console.log(`Provider: ${parsed.response.provider}`);
  console.log(`Model: ${parsed.response.model.id}`);
  console.log(`Tokens: ${parsed.response.usage.totalTokens}`);
}
```

### Auto-Detection

```typescript
import { parseResponse } from '@llm-dev-ops/llm-forge';

// Automatically detects provider from response structure
const openAIResponse = await parseResponse(openAIData);    // Detects OpenAI
const anthropicResponse = await parseResponse(claudeData); // Detects Anthropic
const cohereResponse = await parseResponse(cohereData);    // Detects Cohere
```

### Provider-Specific Parsing

```typescript
import { OpenAIProvider, AnthropicProvider } from '@llm-dev-ops/llm-forge';

const openai = new OpenAIProvider();
const result = await openai.parse(openAIResponse);

const anthropic = new AnthropicProvider();
const claudeResult = await anthropic.parse(anthropicResponse);
```

### Streaming Support

```typescript
import { OpenAIProvider } from '@llm-dev-ops/llm-forge';

const provider = new OpenAIProvider();

// Parse streaming chunks
for await (const chunk of streamingResponse) {
  const parsed = await provider.parseStream(chunk);
  if (parsed.success) {
    process.stdout.write(parsed.response.messages[0].content);
  }
}
```
