Building with AI

No, seriously, you can't trust screenshots anymore

Despite using 5.4 as a daily driver for a few weeks I'm still used to how Opus would understand intent much more

[Matt Arnold @Jahnold]

First impression of gpt-5.5 is that it's just as bad as 5.4 at not taking initiative.

You have to make sure to not phrase your prompt as a question as it will just answer it instead of fixing what you are questioning.

❌Why is the background green not blue - it just tells you why

✅ Change the background to blue, it shouldn't be green - it actually does it

So in summary.

Is GLM-5.1 an Opus level model - no
Would I trust it to write its own specs - no
Can it generate good code if you understand its limitations - yes

[Matt Arnold @Jahnold]

I've been trying out GLM-5.1 in a Ralph loop for a reasonably complex project. Rails API combined with a RN/Expo mobile app

[Matt Arnold @Jahnold]

In the end I split the process down so now I have

Write story - GPT-5.4 high reasoning
Implement - GLM-5.1
Verify - Opus 4.6

This setup is now able to work for much longer before falling over. It's still GLM which trips up but it's less frequent.

@Zhuinden @edandersen Clean Architecture is like keeping all your possessions packed in boxes in case you ever want to move house one day in the future

The human slop is just on a different level there is no way AI can do this 😆

@antirez Codex is a 9/10 dev who is chronically depressed and sucks all the fun out of your life.

Opus is a 8/10 dev who is pleasant to work with.

@VicVijayakumar As others have pointed out - in the UK for every £2 you earn above £100k you lose £1 of your nil rate band.

You don't decline the pay rise though. You just increase your pension contributions to take your taxable pay back below £100k.

Same take home pay, more retirement funds

@hamen This is why I switched from Cursor to Claude Code. Even on the £90/month plan the vibing never stops for me. Nonstop Opus.

You do lose the tight IDE integration but I've been using inside the terminal inside AS/RubyMine/Pycharm as required

[Ethan @LambethEthan]

I love when Claude tells me something will take 6 weeks.

No dude, we are doing it this afternoon.
