I've been using DS 4.1 Flash for a while now as my main workhorse. It's amazing. It's fast and it is also a GREAT debugger - it might not always find the best solution but it will definitely find the problem quickly.

I'm also the CEO of a new company - LunaRoute - so if you want private, fixed cost, we run our own server in the US type of DeepSeek 4.1 Flash check out https://www.lunaroute.com

If you want a trial, hit the contact us and write that you saw this post.

We also have GLM 5.3 (with vision!) and GLM 5.3 Flash - all included.
