Open-source AI gateway and developer portal for APIs and LLMs
Publish REST APIs and LLM endpoints behind one gateway with shared authentication, routing and policy enforcement.
Route prompts across several large language model providers with failover and cost-aware routing, without changing client integrations.
Give API consumers documentation, key management and usage dashboards so integrations do not depend on manual hand-offs.
Apply rate limits, concurrency caps and per-consumer quotas, and turn logged usage into billing or internal chargeback data.
VRAM, throughput and GPU cost calculators plus courses for open-weight LLM deployment
Estimates weight and KV cache memory for a chosen model variant, context length, batch size and quantization so you know whether a GPU will actually fit the workload.
Projects time-to-first-token and tokens-per-second throughput per hardware configuration to help you size for real user traffic.
Converts memory and performance estimates into hourly and per-token economics across hardware configurations.
Reference pages for 500+ model variants and documented hardware benchmarks, keeping sizing inputs in one place.
