Model card & documentation
Source previewRead the publisher’s intended use, setup instructions, evaluations and limitations. The original model card is the source of truth.
Early PPO pilot and production checkpoints at step 20. These configurations differ from the later PPO300 baseline. Original model shards retain their original precision and bytes. Existing safetensors exports are separate derivatives; a BF16 export is not a byte-identical replacement for an FP32 source. Files are arranged by experiment and checkpoint, so the repository root is not a single Transformers frompretrained model. Actor FSDP checkpoints require all four modelworldsize4rank.pt shards and compatible PyTorch/VERL loading or merge utilities. The huggingface/ subdirectory contains configuration/tokenizer metadata, not merged weights. Critics are token-value models, not ordinary causal language models: native critics use a scalar value head. In HL-Gauss, the head has 101 logits over bins spanning [-1.2, 1.2], with centers -1.2 + (i+0.5)2.4/101; compute values as the FP32 softmax-weighted mean of those centers. Gaussian targets use sigma 0.752.4/101. The categorical archive includes the original small mathematical reference implementation, which depends on the original VERL…

Compatibility and lineage
Language coverage was not reported.
Base-model lineage was not included.
Parameter count is not a RAM/VRAM requirement. Check precision, quantization, context length and runtime compatibility in the model card; no hardware or API-cost claim is inferred here.
Use and evaluate
Check license terms and access requirements first. Review the model card’s documented loading instructions, evaluations and safety limitations. Benchmark scores are not imported by this directory, and popularity is not an accuracy ranking.
No model weights are downloaded or executed by AltAPIs. Never enable remote model code without reviewing it.
