Synessa

Managed AI quality. Measure it, improve it, run it for half.

Synessa runs a managed quality loop on production AI agents: we measure how your AI actually performs on real work, fix what the measurement exposes, and route model calls smartly to cut the bill — typically by around half.

What we publish here

Fine-tuned small open-weight models and the datasets behind them, released alongside our articles:

• Fine-Tune Studio — trains small open-weight LLMs on a team's own past decisions for narrow, high-stakes tasks (retail fraud review, invoice coding, payments risk review) and benchmarks them head-to-head against frontier models.

Our models and datasets are gated: access is automatic — we just ask you to share your contact details so we know who is building on our work.
