Route Every Turn.
Not Every Task.

Routers patch your call through to one model for the whole task, like a 1920s switchboard. Parsec picks the right model at every turn, including models trained on your traffic.

The nuance

Why router savings disappoint.

Anyone can save 90% when they stop using Fable, Astra or Kimi to write birthday cards. Real workloads land nearer 15%, for two reasons.

01

Cheap models aren’t cheap

Benchmarks report price per million tokens and leave out cost per task. Smaller models spend more tokens to make up for weaker abilities.

02

Cache economics

Switching models mid-task breaks the cache and you pay twice. A task that is 90% easy rides the expensive model the whole way.

The actual solution

Universal K/V cache. Post-trained teams.

01

Per-turn routing

Our universal K/V cache extends NVIDIA’s cross-model cache transfer research to any conversation length. The next model picks the same next token 89–95% of the time, and a switch costs 15–19% of a full re-read.

02

Models you own

Parsec deploys models post-trained on your traffic, not just public ones.

03

A team, not one model

Model A handles 90% of the conversation. Model B steps in for the hard moment. Efficiency and quality at once.
