Step-3.5-Flash-SFT
Step-3.5-Flash-SFT is a general-domain supervised fine-tuning release for chat models.
This repository keeps the full training interface in one place:
json/: canonical raw training data
tokenizers/: tokenizer snapshots for Step-3.5-Flash and Qwen3, released to preserve chat-template alignment
compiled/: tokenizer-specific compiled shards for StepTronOSS training
Data Format
Each raw shard is a JSON file whose top level is a list of examples.… See the full description on the dataset page: https://huggingface.co/datasets/stepfun-ai/Step-3.5-Flash-SFT.Step-3.5-Flash-SFT-code
Step-3.5-Flash-SFT-code
Code SFT dataset extracted from stepfun-ai/Step-3.5-Flash-SFT, converted to extended OpenAI SFT format, with multi-dimensional quality labels and thinking-mode classification.
