Worked on the vessl-ai/examples repository to deliver two major features for GPT-OSS models, focusing on scalable fine-tuning and robust model serving. Developed a fine-tuning workflow compatible with MXFP4 quantization and YAML-based job configuration, enabling flexible experimentation and deployment. Implemented comprehensive LoRA adapter merging and serving, including max shard size management and enhanced streaming responses for the serve API. Addressed tokenizer and safety issues to improve reliability, such as EOS token handling and infinite-generation prevention. Leveraged Python, FastAPI, and YAML configuration to streamline backend development, accelerate experimentation, and ensure safer, more scalable GPT-OSS model deployments in production environments.
