Visceral wraps your agent, watches its LLM traffic, finds where work is wasted, and makes that call cheaper — but only once it can prove the cheaper call is safe. It is a performance engine, not a router: it surfaces an optimization only when it can prove that optimization is safe, and it never makes anything worse. Two rules sit above everything we do:

Never change your agent's output

An optimization ships only when Visceral can prove it is output-preserving. If it can’t prove it, it doesn’t touch the call.

Fail open

If Visceral is down or degraded, your agent runs exactly as it would without us. We can never be the reason your agent breaks.

Get started

Quickstart

Instrument your agent and see its traffic in three lines of code.

How it works

Observe, prove, optimize — and why we only ship what we can prove.

Install the SDK

Add Visceral to a Python agent that uses OpenAI, Anthropic, or Google.

Privacy & data

Content is stripped in your process — what leaves is metadata, hashed and encrypted.

Turn on optimization

Opt in to proven cache-layout rewrites with a single flag.

API reference

Every endpoint the SDK and dashboard talk to.
