🔗 LiteLLM Integration - Access 100+ AI Models

🎉 NEW FEATURE: NeuroLink now supports LiteLLM, providing unified access to 100+ AI models from all major providers through a single interface.

🌟 What is LiteLLM Integration?

LiteLLM integration transforms NeuroLink into the most comprehensive AI provider abstraction library available, offering:

🔄 Universal Access: 100+ models from OpenAI, Anthropic, Google, Mistral, Meta, and more
🎯 Unified Interface: OpenAI-compatible API for all models
💰 Cost Optimization: Automatic routing to cost-effective models
⚡ Load Balancing: Automatic failover and load distribution
📊 Analytics: Built-in usage tracking and monitoring

🚀 Quick Start

1. Install and Start LiteLLM Proxy

# Install LiteLLM
pip install litellm

# Start proxy server
litellm --port 4000

# Server will be available at http://localhost:4000

2. Configure NeuroLink

# Set environment variables
export LITELLM_BASE_URL="http://localhost:4000"
export LITELLM_API_KEY="sk-anything"  # Any value works for local proxy

3. Use with CLI

# Access OpenAI models via LiteLLM
npx @juspay/neurolink generate "Hello from OpenAI" --provider litellm --model "openai/gpt-4o"

# Access Anthropic models via LiteLLM
npx @juspay/neurolink generate "Hello from Claude" --provider litellm --model "anthropic/claude-sonnet-4-6"

# Access Google models via LiteLLM
npx @juspay/neurolink generate "Hello from Gemini" --provider litellm --model "google/gemini-2.0-flash"

# Auto-select from all available models
npx @juspay/neurolink generate "Write a haiku about AI" --provider litellm

4. Use with SDK

import { AIProviderFactory } from "@juspay/neurolink";

// Create LiteLLM provider
const provider = await AIProviderFactory.createProvider("litellm");

// Generate with auto-selected model
const result = await provider.generate({
  input: { text: "Explain quantum computing" },
});

// Use specific models
const openaiProvider = await AIProviderFactory.createProvider(
  "litellm",
  "openai/gpt-4o",
);
const claudeProvider = await AIProviderFactory.createProvider(
  "litellm",
  "anthropic/claude-sonnet-4-6",
);
const geminiProvider = await AIProviderFactory.createProvider(
  "litellm",
  "google/gemini-2.0-flash",
);

🎯 Key Benefits

🔄 Universal Model Access

Access models from all major providers through one interface:

// Compare responses from multiple providers
async function compareModels(prompt: string) {
  const models = [
    "openai/gpt-4o",
    "anthropic/claude-sonnet-4-6",
    "google/gemini-2.0-flash",
    "mistral/mistral-large",
  ];

  const comparisons = await Promise.all(
    models.map(async (model) => {
      const provider = await AIProviderFactory.createProvider("litellm", model);
      const result = await provider.generate({ input: { text: prompt } });

      return {
        model: model,
        response: result.content,
        provider: result.provider,
        usage: result.usage,
      };
    }),
  );

  return comparisons;
}

// Usage
const results = await compareModels("Explain the benefits of renewable energy");
results.forEach(({ model, response }) => {
  console.log(`\n${model}:`);
  console.log(response);
});

💰 Cost Optimization

LiteLLM enables intelligent cost optimization:

// Use cost-effective models for simple tasks
const cheapProvider = await AIProviderFactory.createProvider(
  "litellm",
  "openai/gpt-4o-mini",
);

// Use premium models for complex reasoning
const premiumProvider = await AIProviderFactory.createProvider(
  "litellm",
  "anthropic/claude-sonnet-4-6",
);

// Let LiteLLM choose optimal model based on configuration
const autoProvider = await AIProviderFactory.createProvider("litellm");

⚡ Load Balancing & Failover

Automatic failover across providers:

# LiteLLM configuration with failover
# litellm_config.yaml
model_list:
  - model_name: gpt-4
    litellm_params:
      model: gpt-4
      api_key: os.environ/OPENAI_API_KEY

  - model_name: gpt-4  # Fallback to Anthropic
    litellm_params:
      model: claude-sonnet-4-6
      api_key: os.environ/ANTHROPIC_API_KEY

    const result = await provider.generate({
      input: { text: "Hello from LiteLLM!" },
      maxTokens: 50,
    });
    console.log("✅ Generation successful:");
    console.log(`Response: ${result.content}`);
    console.log(`Provider: ${result.provider}`);
    console.log(`Model: ${result.model}`);

    // Test different models
    console.log("🧪 Testing multiple models...");

    const models = ["openai/gpt-4o-mini", "anthropic/claude-3-haiku"];
    for (const modelId of models) {
      const modelProvider = await AIProviderFactory.createProvider(
        "litellm",
        modelId,
      );
      const modelResult = await modelProvider.generate({
        input: { text: `Hello from ${modelId}` },
      });
      console.log(`✅ ${modelId}: ${modelResult.content.substring(0, 100)}...`);
    }

    console.log("🎉 All LiteLLM tests completed successfully!");
  } catch (error) {
    console.error("❌ Test failed:", error.message);
  }
}

testLiteLLM();

🚨 Troubleshooting

Common Issues

1. "LiteLLM proxy server not available"

# Check if proxy is running
ps aux | grep litellm

# Start proxy if not running
litellm --port 4000

# Verify connectivity
curl http://localhost:4000/health

2. "Model not found"

# Check available models
curl http://localhost:4000/models | jq '.data[].id'

# Use correct model format: provider/model-name
npx @juspay/neurolink generate "test" --provider litellm --model "openai/gpt-4o-mini"

3. Authentication errors

# Ensure underlying provider API keys are set
export OPENAI_API_KEY="sk-your-key"
export ANTHROPIC_API_KEY="sk-ant-your-key"

# Restart LiteLLM proxy after setting keys
litellm --port 4000

Debug Mode

# Enable debug output
export NEUROLINK_DEBUG=true
npx @juspay/neurolink generate "test" --provider litellm --debug

# Enable LiteLLM proxy debug mode
litellm --port 4000 --debug
