"Half the money I spend on advertising is wasted; the trouble is I don't know which half." -John Wanamaker

This applies even more strongly to model choosing. I know for a fact that majority of my work doesn't require a very strong model, but separating the trivial and non-trivial tasks is a famously hard problem (if at all decidable).

I don't see why it should be all that difficult. All you have to do is first find a library that implements a decent solution to the halting problem and you're off to the races.

Luna is comparable to GPT 5.4 from 4 months ago on many benchmarks. I know many who have said during that time, myself included, that if that's the model they had to use for the rest of their lives, they'd be fine.

GPT 5.4 is/was a very capable model.

Exactly. I haven't reached the "let 1000 agents bloom" mode yet, so currently I'm spending real headspace managing agents doing work, and that work is all important, so why "settle" for sub-frontier models for that work? Maybe I'll get there for non-coding work.

Famously, this is also a problem for human coders in sprint planning.

If you have agents and users, you can run evals and see how far the models go. Luna is not greatest in tool calls, but if you define your problem well and the tools well, it is comparable to Gemini 4 Flash with much lower price tag.

  • Luna is good as an end user model for simple tasks like classification, but not as a coding model. Also do you mean Gemini 3.6 Flash? 4 doesn't exist, and Gemma 4 exists but doesn't have a Flash option.

    • Not my experience at all. I've been driving Luna xhigh in CoPilot CLI since it was released as my daily driver. Good reasoning, no problems with tool calls.

    • Yeah, been running too many evals in the past week I start to mix the versions up. Probably should sleep...

      We run an agent company and outside coding the new Gemini 3.6 Flash and GPT 5.6 Luna are very interesting. Luna can do a bit of research and create reports. Gemini is great for computer use.

      For programming it's all Kimi K3 now.

I get frustrated with a poor quality model leaving my codebase littered with wrong comments, which then later trip up smarter models.

  • This is annoying. Similar with "context poisoning". LLMs can be highly productive... until they're "poisoned" with contradicting inputs / guidance.
