Hi there, I’m fairly decent-ish at programming and few months ago, installed Claude Code and then quickly, I think a month after, jumped from 20$ to Max - because I could do SO many projects at the same time. Opus 4.8 was great then came Fable. Lord it was hungry in terms of tokens but it was awesome. Then Fable was cut off and… things seem different now ? Opus 5.0 varies from all good to incredible stupid with lots of hallucinations and goes around problems that doesn’t exits. Fable is limited like hell and eats tokens like a diabetic on a candy store. Anything mildly complicated that I ask from Fable , 9 out of 10 is “oh I’m on some whatever rails and I will switch to Opus” But the problem I’m getting hurt the most, is token usage. I have several projects that I built with Claude. They work fine and sometimes we do need few changes. Now I wanted to implement a new module and had an idea : that project has a big claude.md file with all the design rules, the architecture and what does and what does not. so : asked Opus 5.0 fresh, to read the claude, get a grip of the project and then in a long prompt what it needed to be done and give me 3 alternatives. burned through 8% of my weekly allowance of the Max to do this in 39 minutes asked Fable fresh, to read the claude.md etc etc and burned 14% of the allowance and did in 29 minutes. Was much more orientated and focused than Opus, which created a lot of loopholes. then wen to to ChatGPT/Codex, used Sol 5.6 , read claude.md , EXACT same prompt. 6% of weekly allowance and 14 minutes. I was surprised - all the alternatives are solid design wise, all work and with diference approaches - but the speed of Codex impressed be but what threw me completely off was token usage : Opus took 8% and Codex 6% to do the exact same task. NOW THE BIG CHANGE : Claude Code is on Max plan. Codex is on a 20$ Plus plan. So Codex use QUITE A LOT LESS tokens than Claude and it was faster. This is because I’m under the impression that a lot of times lately, Claude Code is just slower, hallucinates a lot and tokens are never enough. Opus 4.8 was great , Fable was awesome when it was first released but now, all models seem just… numb , half stupid and heavy token usage for menial tasks sometimes. Why ? submitted by /u/gproenca
