Free / Open-sourceGoogle's family of lightweight, open-weight AI models

Free / Open-sourceA minimal, extensible terminal coding agent you can reshape

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.

High-trust frontier inference, encrypted end to end

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
