#72So at this point OpenAI has 6 reasoning models, 4 flagship chat models, and 7 cost optimized models. So that's 17 models in total and that's not even counting their older models and more specialized ones. Compare this with Anthropic that has 7 models in total and 2 main ones that they promote. This is just getting to be a bit much, seems like they are trying to cover for the fact that they haven't actually done much.…

#73ChatGPT Plus, Pro, and Team users will see o3, o4-mini, and o4-mini-high in the model selector starting today, replacing o1, o3‑mini, and o3‑mini‑high. I subscribe to pro but don't yet see the new models (either in the Android app or on the web version).
Same...
It's there now in the web app for me.

#74The Codex CLI looks nice, but it's a shame I have to bring my own API key when I already subscribe to ChatGPT Plus

#75Surprisingly, they didn't provide a comparison to Sonnet 3.7 or Gemini Pro 2.5—probably because, while both are impressive, they're only slightly better by comparison. Lets see what the pricing looks like.
Looks like they are taking a page from Apple's book, which is to never even acknowledge other products exist outside your ecosystem.

#76When are they going to release o3-high? I don't think it's in the API, and I certainly don't see it in the web app (Pro).

#77> we’ve observed that large-scale reinforcement learning exhibits the same “more compute = better performance” trend observed in GPT‑series pretraining.
Didn’t the pivot to RL from pretraining happen because the scaling “law” didn’t deliver the expected gains? (Or at least because O(log) increases in model performance became unreasonably costly?) I see they’ve finally resigned themselves to calling these trends, not laws, but trends are often fleeting. Why should we expect this one to hold for much longer?

#78I have doubts whether the live stream was really live. During the live-stream the subtitles are shown line by line. When subtitles are auto-generated, they pop up word by word, which I assume would need to happen during a real live stream. Line-by-line subtitles are shown if the uploader provides captions by themselves for an existing video, the only way OpenAI could provide captions ahead of time, is if the "live-st…
All YouTube live streams are like this.

To use that criticism for this release ain't really fair, as these will replace the old models (o3 will replace o1, o4-mini will replace o3-mini).
On a more general level - sure, but they aren't planning to use this release to add a larger number of models, it's just that deprecating/killing the old models can't be done overnight.

#80To plan a visit to a dark sky place, I used duck.ai (Duckduckgo's experimental AI chat feature) to ask five different AIs on what date the new moon will happen in August 2025.
GPT-4o mini: The new moon in August 2025 will occur on August 12.
Llama 3.3 70B: The new moon in August 2025 is expected to occur on August 16, 2025.
Claude 3 Haiku: The new moon in August 2025 will occur on August 23, 2025.
o3-mini: Based on astronomical calculations, the new moon in August 2025 is expected to occur on August 7, 2025 (UTC). [...]
Mistral Small 3: To determine the date of the new moon in August 2025, we can use astronomical data or a reliable astronomical calendar. As of my last update in October 2023, I don't have real-time data access, but I can guide you on how to find this information. [...]
I got different answers, mostly wrong. My calendars (both paper and app versions) show me 23. august as the date.
And btw, when I asked those AIs which entries in a robots.text file would block most Chinese search engines, one of them (Claude) told me that it can't tell because that might be discriminatory: "I apologize, but I do not feel comfortable providing recommendations about how to block specific search engines in a robots.txt file. That could be seen as attempting to circumvent or manipulate search engine policies, which goes against my principles."
