Pricing seems good, but the open question is still on tool calling reliability. Input: $1.25 / 1M tokens Cached: $0.125 / 1M tokens Output: $10 / 1M tokens With 74.9% on SWE-bench, this inches out Claude Opus 4.1 at 74.5%, but at a much cheaper cost. For context, Claude Opus 4.1 is $15 / 1M input tokens and $75 / 1M output tokens. > "GPT-5 will scaffold the app, write files, install dependencies as needed, and show a…

And they included Flex pricing, which is 50% cheaper if you're willing to wait for the reply during periods of high load. But great pricing for agentic use with that cached token pricing, Flex or not.

What's going on with their SWE bench graph?[0] GPT-5 non-thinking is labeled 52.8% accuracy, but o3 is shown as a much shorter bar, yet it's labeled 69.1%. And 4o is an identical bar to o3, but it's labeled 30.8%... [0] https://i.postimg.cc/DzkZZLry/y-axis.png

Wow imgur has gone to shit. I open the image on mobile and then try to zoom it and bam some other “related content” is opened…!

Damn, you guys are toxic. So -- they did not invent AGI yet. Yet, I like what I'm seeing. Major progress on multiple fronts. Hallucination fix is exciting on its own. The React demos were mindblowing.

Assuming even 10% of YouTube commenters are real people.

Yeah I'm surprised they used that example. The correct (and PhD-level) response would have been to refuse or redirect to a better explanation

Watching the livestream now, the improvement over their current models on the benchmarks is very small. I know they seemed to be trying to temper our expectations leading up to this, but this is much less improvement than I was expecting

It is at least much cheaper and seems faster. They also announced gpt-5-pro but I haven't seen benchmarks on that yet.

I am hoping there is a "One more thing" that shows the pro version with great benchmark scores

The marketing copy and the current livestream appear tautological: "it's better because it's better." Not much explanation yet why GPT-5 warrants a major version bump. As usual, the model (and potentially OpenAI as a whole) will depend on output vibe checks.

It has the last ~6 months worth of flavor of the month Javascript libraries in it's training set now, so it's "better at coding".

How is this sustainable.
