CodeGateway vs OpenRouter

Offers robust serverless inference and GPU clusters for open models, but features a narrower selection of proprietary models.

Features adaptive LLM routing and automatic failover, but lacks OpenRouter's massive ecosystem of community-rated model endpoints.

SpecialistDelivers exceptional inference speed and high-throughput performance for open models, but focuses primarily on hosted weights rather than multi-provider aggregation.

One OpenAI-compatible API key for 500+ AI models

Free / Open-sourceProvides self-hosted and Python SDK control over 100+ LLMs, but requires setting up your own infrastructure.

SpecialistLow-cost serverless inference APIs for 200+ open models

One unified API for 100+ AI models, with insurance when output disappoints

One API for fast, cost-predictable inference on LLMs and multimodal models

Aggregates hundreds of foundation models and agentic tools under one endpoint, but lacks OpenRouter's community popularity and extensive prompt tuning.

One OpenAI-compatible key for discounted GPT, Claude and Gemini access

Delivers advanced enterprise observability, guardrails, and caching, but focuses more on governance than simple model aggregation.

Provides unified API access and cost tracking across multiple AI providers, but supports fewer niche open-weight models than OpenRouter.
