Kimi K2.6 thinks longer than K2.5 but the answers are actually better, early side-by-side notes

Kimi K2.6 spends noticeably more time in the thinking phase than K2.5. Same settings, same tasks. The answers come out consistently better across the cases our team compared side by side.
Real tradeoff: more latency, better output. That is worth knowing before you decide whether to swap.
We ran both through our AI router so the side-by-side was just a model string swap, no rewiring. That made it easy to compare output quality on identical prompts. What stood out, K2.6 takes longer in the thinking phase but consistently lands better answers at the end. Not a universal improvement, but the delta is there on real tasks.
On OpenClaw specifically, K2.5 underwhelmed enough that one engineer was unsure whether the bottleneck was the model or the harness. K2.6 feels better suited to that use case based on early tests, though the full benchmark is not done yet.
Nothing conclusive yet. Sharing this because practitioner observations on the latency versus quality tradeoff usually only surface after someone has burned a week finding out themselves.
Anyone else running K2.6 against K2.5 on agentic workloads? Curious whether the thinking time difference holds on your tasks and whether you are seeing the same quality delta.
Disclosure, I work at Orq.

What about with thinking off

Yo no hice pruebas exaustivas aun, pero lo utilice para debuguer un paquete escrito en rust por Big Pickle; lo corrigio a la primera, eso si con cierta latencia. Voy a seguir probandolo obiviamente, de momento me parecio un modelo competente.

According to ArtificialAnalysis, 2.6 takes roughly twice the output tokens for their benchmark suite compared to 2.5.

Haven't tried Kimi 2.6 yet in earnest, but switched from that to GLM 5 then 5.1. Was a major improvement.
