Personal view. On the DoW deal, time and time again I witness how OpenAI operates thoughtfully and diplomatically when it comes to raising the bar on safety. I also believe that figuring out how to deploy powerful new technology in the pursuit of national security (not just the USA) is important.

The company deeply understands what it can and cannot reasonably have control over and focuses instead of setting the right guardrails to ensure that deployment is aligned with what is considered acceptable and safe.

I am proud of the level of transparency provided in the blog post, and hope that other companies, including Anthropic, were as transparent on prior and future deals they make.

Companies with customer service as bad as @Xfinity 's should not exist in the 21st century.

Meta changed its policies so 1-800-ChatGPT won't work on WhatsApp after Jan 15, 2026.

Luckily we have an app, website, and browser you can use instead to access ChatGPT.

[Paul Baltescu @pauldb89]

@Xfinity no internet, customer support offered by a bot and the ability to book a technician in two days time is unacceptable. I guess I won’t be your customer then.

@CaltrainAlerts maybe some update on when the next southbound trains depart from sf?

[Andrew 🌁 @Andrew__G23]

@CaltrainAlerts Trains are 40+ mins late this is fucking unacceptable we shouldn’t have to pay for this shitty service.

[MHBSP @MHB_101813]

@CaltrainAlerts fix the scheduling problem by monday next week or start refunding people their money!! it’s not the heat restriction. you were late on every single train all last week. get your shit together!

@vfsglobalcare @SBR2022_ applied for a UK visa at VFS San Jose. UKIV replied that they received the biometrics, but not the documents including the passport. Can you please follow up to her DMs and help her track what happened here?

We just rolled out enhanced controls for File Search in the Assistants API to help improve the relevance of your assistant's responses. You can now inspect the search results returned by the tool and configure their rankings. https://t.co/MW9ehuLYiC

[OpenAI Developers @OpenAIDevs]

Introducing a series of updates to the Assistants API 🧵

With the new file search tool, you can quickly integrate knowledge retrieval, now allowing up to 10,000 files per assistant. It works with our new vector store objects for automated file parsing, chunking, and embedding.

[OpenAI Developers @OpenAIDevs]

Introducing the Batch API: save costs and get higher rate limits on async tasks (such as summarization, translation, and image classification).

Just upload a file of bulk requests, receive results within 24 hours, and get 50% off API prices: https://t.co/ls8DjR6qA9

We have reached an agreement in principle for Sam Altman to return to OpenAI as CEO with a new initial board of Bret Taylor (Chair), Larry Summers, and Adam D'Angelo.

We are collaborating to figure out the details. Thank you so much for your patience through this.

I am deeply pleased by this result, after ~72 very intense hours of work. Coming into OpenAI, I wasn’t sure what the right path would be. This was the pathway that maximized safety alongside doing right by all stakeholders involved. I’m glad to have been a part of the solution.

[Paul Baltescu @pauldb89]

@eshear Thank you!

[Sam Altman @sama]

i love openai, and everything i’ve done over the past few days has been in service of keeping this team and its mission together. when i decided to join msft on sun evening, it was clear that was the best path for me and the team. with the new board and w satya’s support, i’m looking forward to returning to openai, and building on our strong partnership with msft.

If you’re learning a second language, I highly recommend practicing with voice mode! (I set my custom prompt so that the model knows to stay in Portuguese, but to correct my grammar if I make mistakes or teach me the translation if I drop back into English)
