[Laya Minecraft](): Public weights, question signatures and train\_report.json; [Laya]() runtime Licence: Apache-2.0 model card [Laya Minecraft facts]() [Source]() By Thomas Tesche · Weights upload: 2026-11-07 · OPEN An English [Laya]() fine-tune for a Minecraft agent. Code removes impossible actions; the model chooses an intent and answers a danger question, then an executor acts and a verifier checks progress. The encoder is frozen during this training run. Its reported evaluation contains training or calibration overlap. ## Facts - Base: convaiinnovations/laya, ModernBERT-large - Inputs: English game-state descriptions and valid action candidates; intent and in\_danger choice questions - Training: 2,564 verified decision ticks, four epochs; temperatures fitted on 284 calibration items - Licence: Apache-2.0 model card - Access: Public weights, question signatures and train\_report.json; [Laya]() runtime ## Claims and sources - **VENDOR-REPORTED**: The maker reports accuracy 0.9301 before fine-tuning and 0.9325 after, with ECE moving from 0.0625 to 0.0435 on 415 items. Four items overlap training or calibration, so this is not a strictly held-out result. No score or noul items were trained.
