What does this mean, that you can take Kimi and RL finetune it a little more and blow the big AI shops out of the water? Would this have been extensively fine

What does this mean, that you can take Kimi and RL finetune it a little more and blow the big AI shops out of the water? Would this have been extensively fine tuned, beyond what Anthropic/OAI would do themselves? I guess this is Cursor's own benchmark, so you can finetune on your own dataset and get better results on your own specific tasks I guess.
