AI21 Gateway reduces agent token costs through adaptive routing and context optimization.
AI21 Gateway is a drop-in endpoint for agent teams that reduces token waste through per-agent tuning, adaptive model routing, context compaction, and caching.
The gateway evaluates savings recommendations against coding benchmarks and lets customers approve changes before production; it integrates by changing an agent's API base URL.


Hosted gateway for routing and governing traffic across hosted and self-hosted AI models.



Portkey AI provides a gateway platform for managing and observing large language model deployments.


Control plane governing AI access, spend and observability across models, agents and tools.


A unified OpenAI-compatible API and gateway for accessing hundreds of LLMs from many providers.


Weave Router is a drop-in proxy that routes each inference request to the lowest-cost model that answers at frontier parity.


Conifer Gateway is one OpenAI- and Anthropic-compatible endpoint for more than 200 models.


Secure enterprise portal for multiple large language model platforms with reusable language skills and usage-based pricing.


Open source AI gateway routing every model behind one zero-markup OpenAI-compatible endpoint.


IonRouter is a high-throughput, low-cost inference API and drop-in OpenRouter alternative powered by Cumulus Labs' IonAttention engine.
