can't believe I went all the way to Pyongyang to see statues of dictators when I could have just waited for the Trump library

if you studied secret police in history class - who'd beat citizens and drag them off in unmarked vehicles - and thought, "I'd obviously have spoken up if I had been around back then"

well, now's your chance

Americans will be better off when he and his party are removed from power

5 years on from January 6th it's worth reflecting on just how much contempt Donald Trump has for us, the American people. he’s pardoned criminals who've defrauded us, used our tax money to enrich himself and his friends, and continues to attack our democratic rights

2026 is shaping up to be an incredibly gay year

how was your year with chatgpt?

setting "prompt_cache_retention" to "24h" in the Responses API can lead to significant cost and latency improvements in gpt-5.1, since prompts will be cached much longer than the normal 5-10 minutes

Introducing GPT-5.1 for developers GPT-5.1 is now available in the API, bringing faster adaptive reasoning, extended prompt caching, improved coding performance, and new apply_patch and shell tools.

developers didn't have to wait long - gpt-5.1 is now available in the API! openai.com/index/gpt-5-...

gpt-5.1 is now available in ChatGPT! smarter, faster, and with more options to customize its personality - because sometimes you don't need to be told that every question is a great question

exciting to see my current and former employers working together to scale AI compute!

just made a donation to the Python Software Foundation. groups like the PSF should not be forced to add/remove unrelated policies in order to receive scientific grants.

seems like a good day to remind everyone of the temporary chat button in ChatGPT, which will disable memory and remove the conversation from your history

another successful DevDay in the books. thanks to everyone who attended and also to our incredible events team - it was our biggest one yet!
