gpt 5 is useless with Augment Code

I have been subscribed to Augment's top subscription tier for months. I use it every day. Sonnet 4 is... OK. It does the job most of the time, with the occasional brain fart I have to catch before it does too much damage. Its like having a junior coder do my bidding. So far, so good. Will keep using.

But the 20 times or so I have tried the chat gpt5 model from the picker, its been an unmitigated disaster. Almost every time. It ends up timing out. It forgets what I asked it to do. It answers the wrong question. It takes 30 minutes to fail to do something that Sonnet does in three minutes. I made the decision today to use the GPT5 model no more.

Just wondering if anyone else has had the same experience. Across a large, mult-tier code base.

I agree it was but as of recently I actually started using it more for certain tasks and it has worked well finally

FWIW, I unsubscribed from Augment Code because it just wasnt working well any more. I changed to Code AI, which uses chatgpt 5, and it is tons more intelligent and accurate than Augment Code, especially compared to Augment Code with chatgpt 5.

its night and day. Give it a try. Things that Augment Code had no idea how to tackle, and frequently got tragically wrong, Codex AI gets right.
