Have you tried the large open source code models?

I use glm-5.1 and occasionally deep seek v4.

They are as good or better than Claude's latest models.

And significantly cheaper. I've converted 3 of my engineer friends as well. All three have dropped their $200 month plans they had with anthropic.

We've all been a bit shocked at just how good these models are now.

If you "have" tried GLM (I specifically find it shockingly good for code). Did you not think it's not competitive to Claude, and why?

I use GLM-5.1.

It's good enough for personal stuff. It doesn't compare to the latest Opus I use at work. You can certainly argue I don't need Opus for work, but there is clearly a difference.

Also, at least with z.ai, GLM-5.1 is s l o w! After using Claude at work, I get really impatient with GLM-5.1 at home. When doing "true" vibe coding (i.e. not really examining the code), Opus is a ton faster (easily 5x).

But yeah, I'm not willing to personally pay for the frontier models. I won't even renew my annual Z.ai plan - it's become too expensive.

Hmm, I use opencode subscription, and glm seems just as fast from the tests I've tried to compare between the two. Tbh it mostly took Claude longer (mostly significantly longer) for the same tests.

Also, and I know you may not want to answer. But could you give me an idea of the type of thing you found glm to be worse with?

I think I've been fairly unbiased in testing a bunch of different development tasks. But am curious if maybe it performs well for some stuff and not others. So if you could share what you feel it's worse at.

Also are you an experienced developer or less experience?

		Perhaps opencode zen isn't using z.ai as a provider?

I'll repeat something I wrote on an entirely separate HN submission.

When DeepSeek V4 Pro came out, I had been mostly coding with GLM-5.1 on a Z.ai coding plan.

I had a large analysis task on a relatively complex codebase. I decided to try the models out.

GLM-5.1 did acceptably but got a few things wrong (easily corrected) and took quite a while to get there.

Opus 4.6 burnt through the US$10 budget I had given it in about 10-15 min, without ever returning from the first prompt.

DeepSeek V4 returned a full analysis within 2-3 min, and I carried on all the way to implementing the feature I was after. Total cost less than US$1.00.

I now mostly alternate between GLM-5.1 and DeepSeek V4 Flash, with an occasional dip into V4 Pro for more complex analyses.

task i am working on right now at work is comparing two verisions of apis and documenting responses in their outputs. i suspect a vast majority of work at entrprise is of similar complexity.

right now everyone is using latest and greatest to do dumb stuff like that. that would change fast if companies start caring about costs.

What is the best IDE UI to use them? I don’t like CLIs.

		Personally I'm happy with opencode right now
