Looking for OpenRouter itself? OpenRouter: Unified API gateway to access hundreds of AI models across providers
NVIDIA NIM hosts optimized inference microservices for dozens of leading open-weight models, including Nemotron, DeepSeek, and Llama variants. Developers can generate free API keys to prototype applications with generous rate limits without running local GPU hardware. It also offers agentic skills, workflow blueprints, and exportable containers for production deployment.
AI/ML API is a unified inference gateway that gives developers access to hundreds of AI models across text, image, video, audio, and embeddings through an OpenAI-compatible interface. It includes an interactive playground for testing prompts and comparing model outputs before deployment. It also supports direct MCP server integration for agent workflows in Claude and Cursor.
Bytez provides serverless AI inference through a single unified API key, supporting thousands of open-source and proprietary models across modalities like text, vision, and audio. It allows developers to test, compare, and deploy models without provisioning or managing infrastructure.
Cheaper Inference is an AI routing marketplace that sells access to models from providers like OpenAI, Anthropic, and DeepSeek at discounts up to 76%. Developers switch upstream calls simply by pointing their existing OpenAI SDK base URL and API key to the platform. It features usage-based pricing with no commitments and offers optional Zero Data Retention (ZDR) routing.
FreeLLMAPI is an open-source local proxy and router that aggregates free quotas across dozens of AI providers into a single unified endpoint. It automatically handles failover on rate limits, tracks per-key usage, and stores provider credentials with AES-256 encryption. It allows developers to plug free model access directly into coding agents, CLIs, and OpenAI-compatible apps.
