Key Points

The author claims Kimi K2.6 can serve as a practical replacement for Opus 4.7, with about 85% task coverage at reasonable quality.
While Kimi K2.6 is not better than Opus 4.7 in every way, it offers strong capabilities including vision and very good browser use.
The author reports successfully shifting some personal workflows to Kimi K2.6, particularly for long-horizon tasks.
The post argues that very large “frontier” LLMs may not deliver fundamentally new capabilities, and it notes that users are complaining about usage limits—suggesting local deployment may be preferable.

After testing it and getting some customer feedback too, its the first model I'd confidently recommend to our customers as an Opus 4.7 replacement.

It's not really better than Opus 4.7 at anything, but, it can do about 85% of the tasks that Opus can at a reasonable quality, and, it has vision and very good browser use.

I've been slowly replacing some of my personal workflows with Kimi K2.6 and it works surprisingly well, especially for long time horizon tasks.

Sure the model is monstrously big, but I think it shows that frontier LLMs like Opus 4.7 are not necessarily bringing anything new to the table. People are complaining about usage limits as well, it looks like local is the way to go.
