NeoHorse is TokenRhythm's family of open-weight causal language models for text-based agent workflows, including tool use, coding, and instruction following. NeoHorse-1 uses routing-guided agentic post-training: a harness assigns tasks to a heterogeneous model pool, records tool interactions and outcomes, estimates capability demand, and feeds capability-level feedback into later training mixtures. Updated models can return to the harness in an evaluation-selection-update loop intended as a prototype for recursive self-improvement. NeoHorse-1 is released in approximately 4B and 9B parameter variants, post-trained from Qwen3.5 models, with text input and text output interfaces and deployment examples for vLLM and SGLang. The related NeoHorse-Jev-4B model uses prefill-only inference to return structured Choice, Noul, and Score decisions and probabilities for routing requests, selecting tools, or controlling workflows. The models are released under the Apache License 2.0.

A family of lightweight models trained from Qwen 3.5 for coding and tool use. Its training harness routes tasks among models and uses recorded actions and outcomes to shape later training.
