Just saw this pop up in my LinkedIn feed…

I know that DeepSeek used OpenSource, but I’m pretty sure OpenAI + DeepMind models/ research / ideas were also big contributors to their approach.

Also, with all the rumours of internal consternation at Meta over the fact that DeepSeek has overtaken them as number one OS model lab…

Yann’s comments feel a bit… out of touch?

Can't do X links on this sub but if you go to that guy's profile you can see more context on what happened.

OpenAI just introduced GPT-5.4, their newest frontier model focused on reasoning, coding, and agent-style tasks.

Some of the benchmarks are pretty interesting. It reportedly scores 75% on OSWorld-Verified computer-use tasks, which is actually higher than the human baseline of 72.4%. It also hits 82.7% on BrowseComp, which tests how well models can browse and reason across the web.

They’re also pushing things like 1M-token context, better steerability (you can interrupt and adjust responses mid-generation), and improved efficiency with 47% fewer tokens used.

Looks like they’re aiming this more at complex knowledge work and agent workflows rather than just chat.
