Sageros is the agent-centric AI gateway that turns stateless LLM calls into stateful, governed, zero-trust agent sessions - with loop-breaking, human-in-the-loop control, and semantic caching that pays for itself.

Governs agents across every major model provider
Legacy LLM proxies count tokens on isolated requests. But an agent is a loop - dozens of interdependent calls, tools, and decisions under one intent. Sageros governs the whole session.
Everything an enterprise needs to run agents safely at scale - supervision, savings, and security.
Visual session lifecycles, an anti-loop breaker that kills runaway spend, and JIT approvals that freeze destructive actions until a human signs off.
Cosine-similarity matching serves near-duplicate prompts from cache - cutting latency and cost while you watch the savings tick up in real time.
Inline PII redaction runs today. Global policies across every agent - GDPR egress rules and prompt-injection filtering - are in active development.
Today Sageros runs as a cloud gateway: your traffic passes through our infrastructure. The target below - a Sageros node inside your own network, where secrets never leave your boundary - is what we are building next, not what ships today.

We are pre-customer and building in the open. The problem we are chasing: giving platform teams a kill-switch and audit trail for agents in production - without slowing engineers down.
The short version of what Sageros is and how it helps.
Sageros is an AI gateway that sits between your AI agents and model providers and turns loose, stateless LLM calls into supervised, governed sessions - so you can watch what your agents do, stop them when they misbehave, and pay less.
A normal proxy sees one request at a time. Sageros groups every call an agent makes under a single session, so it understands the whole task - and can detect infinite loops, enforce policies, and require human approval across the entire session, not just one call.
Two ways. Its semantic cache answers near-duplicate prompts without calling the model, and its anti-loop breaker stops agents from burning tokens in endless retries. Both cut your provider bill automatically.
Honestly: we are early. Today Sageros runs as a cloud gateway, so your traffic and provider keys pass through our infrastructure - we are the custodian and we say so. It redacts structured PII before egress. We hold no certification yet; SOC 2 and self-hosted deployment are on the roadmap. Full status on the Security page.
Point your agent's model client at the Sageros gateway and add your session id - a single line of configuration. Supervision, caching, and policy enforcement turn on automatically. See the docs.
