UltraIF-8B-SFT is fine-tuned from Llama-3.1-8B, using 175k UltraIF SFT Data.

UltraIF first constructs the UltraComposer by decomposing user instructions into simplified ones and constraints, along with corresponding evaluation questions. This specialized composer facilitates the synthesis of instructions with more complex and diverse constraints, while the evaluation questions ensure the correctness and reliability of the generated responses.

Then, we introduce the Generate-then-Evaluate process. This framework first uses UltraComposer to incorporate constraints into instructions and then evaluates the generated responses using corresponding evaluation questions covering various quality levels.
