Inference platform for long-running AI agents, using dynamic context compression and caching
Subconscious is a Cambridge, Massachusetts company, born out of MIT research on inference optimisation, that runs an inference platform for long-horizon AI agents. Its dynamic context compression and caching let agents that consume more than 200k tokens finish tasks up to 2x faster, stretch effective context windows past 5M tokens and cut costs by up to 80%, the company says. On the TriE benchmark it reports 2x faster completion than SGLang, and on DeepSWE it reports higher accuracy at lower cost per task with GLM 5.2. It is sold as a cloud service or on-prem deployment and can power coding agents such as Claude Code, Codex and Copilot. On 22 September 2026 it announced $5.1M raised across a pre-seed and a seed, both led by MassVentures. Co-founders are Jack O'Brien (CEO) and Hongyin Luo (CTO).
