kimi-linear-48b-a3b-target-matched-math-240k

239,467 rows of math-reasoning trajectories regenerated against moonshotai/Kimi-Linear-48B-A3B-Instruct as the target model. Used to train DFlash speculative-decoding drafters in la-draftery.

What "target-matched" means

The user prompts come from the Nemotron v2 math corpus. The assistant completions in this dataset are the target model's own outputs — each prompt was sent to moonshotai/Kimi-Linear-48B-A3B-Instruct and its completion was captured. Drafters trained on target-matched data learn to predict exactly the tokens the target would emit, which is what speculative decoding requires for high acceptance length.
