An open-weights System One model from Convai Innovations. A fully fine-tuned ModernBERT-large encoder with a from-scratch decision head that scores one marker per option and answers every question in a single 33–39 ms pass. Runs on your own CPU or GPU.
meraGPT's hosted decision model (state-decider-1). Answers yes/no, choice and rubric-score questions over one state as calibrated distributions in a single pass, on the System One schema, so the typesafe-sdk works by changing its base URL.

Questions
What is the difference between laya and state-decider-1?
laya is from Convai Innovations and state-decider-1 from meraGPT. laya has open weights you can download and run; state-decider-1 is only available as a hosted API. Both answer choice, score, noul, classify and route questions. state-decider-1 reads up to 4K tokens of state, against 512 tokens for laya. laya is licensed apache-2.0; state-decider-1, proprietary.
Which is more accurate, laya or state-decider-1?
Only state-decider-1 publishes an accuracy figure (76.8% on typed-decisions benchmark (400 cases, 2,000 decisions; teacher-ensemble references), single run); laya does not, so there is no comparison to make without your own test.
Which is cheaper, laya or state-decider-1?
laya: Free (open weights). state-decider-1: $0.03 / $0 per 1M. Open weights cost nothing per call beyond your own hardware.
Can I run laya or state-decider-1 locally?
laya yes — systemone pull convai-innovations/laya downloads its weights. The other is only served as a hosted API.
