Source description
SpaceLLM Single Turn QA is a parameter-efficient LoRA adapter fine-tuned on top of openai/gpt-oss-20b for single-turn question answering and instruction following. Only the attention projection layers (, , , ) are trained; the full transformer backbone remains frozen, keeping the adapter extremely lightweight while steering the model's outputs toward accurate, focused single-turn responses.

This adapter was trained using LoRA on the attention projection layers only, keeping the base model frozen. This makes the adapter lightweight to store and share while adapting the model's behavior for single-turn Q&A and instruction-following tasks.
