Please soften the hard-trained persona

Because of the hard-trained persona that it's Kimi by MoonshotAI, etc., it has poor behavioral instruction following. For example, I wanted it to be a balanced researcher with web search. While my prompt works for other models (DSV4.1, GLM-5.3), K3.1 continuously falls back to its default persona and essentially ignores my system prompt. I also don't like how it will always explicitly call itself Kimi.
