Best OpenRouter alternatives

Inference cloud running open models on Cerebras wafer-scale chips for very high tokens-per-second throughput, with an OpenAI-compatible API.

Inference platform running on custom LPU chips rather than GPUs, delivering notably fast token generation speeds for open models like Llama and DeepSeek.

Open-source Python library and proxy server that calls 100+ LLM providers through one OpenAI-compatible interface, with built-in cost tracking and load balancing.

Platform for running open-source machine learning models via a simple API, covering LLMs, image generation, and other model types with pay-per-use pricing and no infrastructure to manage.

Cloud platform for running and fine-tuning open-source LLMs at scale, offering fast inference, dedicated GPU clusters, and a library of pre-hosted open models.

Open-source LLM observability proxy that sits between your app and a model provider, logging requests, costs, and latency with a one-line integration change.

AI gateway for production LLM apps, combining provider routing and failover with caching, guardrails, and observability in one managed layer.
