5 is a breakthrough at reducing OpenAI's electric bills.

As someone who likes this planet, I'm grateful for that.

GPT-5 is legitimately a big jump whe it comes to actually do things you ask it and nothing else. It predictable and matches Claude in tool calls while being cheaper.

The only issue I've had with gpt5 coding is that it seems to really want to modify a ton of stuff

I had it update a test for me and it ended up touching like 8 files that was all unnecessary

Sonnet on the other hand just fixed it

I have consistently had worse performance from GPT-5 in coding tasks than Claude across the board to the point that I don't even use my subscription now.

Chatgpt.com is ironically the worst way to try gpt-5
