​
General

MegaLLM is a universal AI platform that connects 70+ large language models from leading providers like OpenAI, Anthropic, and Google through a single API. Think of it as your “super-API” for AI - instead of integrating with multiple providers separately, you get access to all models through one unified interface.
We currently support 70+ models including:
  • OpenAI: gpt-5, gpt-4.1, gpt-4o, gpt-3.5-turbo
  • Anthropic: claude-opus-4-1-20250805, claude-sonnet-4, claude-3.5-sonnet, claude-3.7-sonnet
  • Google: gemini-2.5-pro, gemini-2.0-flash-001
  • Embedding Models: Various text embedding options
New models are added regularly as they become available.
Yes! Switching models is as simple as changing one parameter in your API call. You can also set up automatic fallbacks between models.
# Switch models instantly
response = client.chat.completions.create(
    model="gpt-5",  # Change this to any supported model ID
    messages=[{"role": "user", "content": "Hello!"}]
)
No! That’s the beauty of MegaLLM. You only need one MegaLLM account to access all 70+ models. We handle the complexity of managing multiple provider relationships, so you don’t have to.

Platform Features

MegaLLM offers several unique advantages:
  1. One API for All: Access 70+ models through a single, consistent interface
  2. Automatic Fallbacks: If one model fails, automatically switch to another
  3. Unified Billing: One invoice for all your AI usage
  4. Performance Optimization: Intelligent routing and load balancing
  5. Cost Management: Optimize spending across different models
When you configure fallback models, MegaLLM automatically routes your request to backup models if the primary model encounters issues like:
  • Rate limits
  • Temporary outages
  • Timeout errors
  • Capacity constraints
This ensures your application never goes down due to a single model failure.
response = client.chat.completions.create(
    model="gpt-5",
    messages=messages,
    fallback_models=["claude-opus-4-1-20250805", "gemini-2.5-pro"]
)

​
Pricing & Billing

You pay based on actual token usage, just like with individual providers. However, MegaLLM offers several advantages:
  • Unified Billing: One invoice for all models
  • Volume Discounts: Better rates for high usage
  • Cost Optimization: Tools to minimize spending
  • Transparent Pricing: Clear cost breakdown by model
See our Models page for detailed pricing information.
For most users, MegaLLM offers better value because:
  1. Volume Pricing: We pass on volume discounts to customers
  2. Reduced Development Costs: No need to integrate with multiple APIs
  3. Operational Savings: Less monitoring, fewer rate limit issues
  4. Fallback Benefits: Higher uptime means less lost revenue
Plus, you save significant engineering time by not having to manage multiple provider integrations.
Yes! MegaLLM provides comprehensive cost controls:
  • Daily/monthly spending limits
  • Per-model budget allocation
  • Usage alerts and notifications
  • Cost optimization recommendations
  • Automatic fallback to cheaper models when limits are reached

​
Technical Integration

Yes! MegaLLM is fully compatible with OpenAI’s API format. Migration is typically just changing the base URL:
# Before (OpenAI)
client = OpenAI(api_key="sk-...")

# After (MegaLLM)
client = OpenAI(
    base_url="https://ai.megallm.io/v1",
    api_key="your-megallm-key"
)
All your existing code continues to work unchanged.
We also support Anthropic’s API format perfectly:
# Anthropic format works too
client = Anthropic(
    base_url="https://ai.megallm.io",
    api_key="your-megallm-key"
)
You can even mix and match - use OpenAI format to access Claude models, or vice versa.
Different models have different strengths. MegaLLM makes it easy to route requests to the best model for each task:
# Code generation
code_response = client.chat.completions.create(
    model="gpt-5",  # Great for code
    messages=[{"role": "user", "content": "Write a Python function..."}]
)

# Creative writing
creative_response = client.chat.completions.create(
    model="claude-opus-4-1-20250805",  # Great for creative tasks
    messages=[{"role": "user", "content": "Write a story..."}]
)

# Fast responses
quick_response = client.chat.completions.create(
    model="gpt-4o-mini",  # Fast and efficient
    messages=[{"role": "user", "content": "Quick question..."}]
)
MegaLLM significantly reduces rate limit issues:
  1. Distributed Load: Requests are distributed across multiple providers
  2. Automatic Fallbacks: Switch to available models when limits hit
  3. Intelligent Routing: Route requests to models with available capacity
  4. Rate Limit Prediction: Avoid hitting limits with predictive routing
You’ll experience much higher effective rate limits than any single provider.
