#devday

It was fun sitting down with a few of our ambassadors from all over the world at #DevDay to chat about the community program. Stay tuned! 😁

第一视角：Tibo 现场按了Reset Button，全场鼓掌像看世界杯决赛。 按完我打开Codex一看：额度还是0。 原来那颗蓝按钮是蓝牙音箱。 @thsottiaux 下次按之前先 ping 一下服务器谢谢 #DevDay #OpenAI #CodexReset #TiboButton

😂堪称商战教科书！Sam Altman刚宣布Dots，Elon把 Bot下载页！ 你搜对手新品，结果进了自己家。 发布会当天最贵的不是模型，是最短那个入口。 #ElonMusk #SamAltman #OpenAI #xAI #Dots #GrokBot #商战教科书

Two things went wrong during the @OpenAI #devday demos: • During the dot demo, the dot wasn’t responding. • In another demo where Codex was being used, voice chat wasn’t working at all. And now I can’t even find these clips on the official stream anymore. 👀 But I recorded them live while the stream was happening.

Just arrived at @OpenAI #DevDay, and I’m predicting proactive intelligence will steal the show. We’ve gone from statistics to machine learning to intelligence. Now the next step is AI that doesn’t just respond, but anticipates. But, the big question: how do we make that happen in a way that is genuinely useful and trustworthy? Excited to learn from the builders here today. Vibes are awesome.

Woo hoo! OpenAI highlights HubSpot partnership on main stage at #DevDay. Today was a special day for me. Was so cool to see @sama from @OpenAI feature @HubSpot from the main keynote stage at their Dev Day event. HubSpot and OpenAI are the two most impactful companies in my life. HubSpot, for obvious reasons and OpenAI for less obvious ones. My relationship with Sam and OpenAI goes back a bit: 1) Got access to the GPT-2 API so had my "moment of magic" well before ChatGPT launched. 2) Have been using OpenAI's APIs and platform to build apps and agents for years. They *really* understand developers and have an amazing dev experience. 3) Sold the chat .com domain name to them and as a result was able to become an investor in the company. 4) They're the primary AI platform that HubSpot partners with and builds with -- as highlighted today. My congrats to the entire OpenAI team for today's event. I know how much work goes into putting together an event like this. And it was clear from the vibes how much you folks *care*. Cheers.

A few of our Codex Ambassadors flew in from all over the world and are ready for #DevDay!!!! @OpenAIDevs @OpenAI 🫶

OpenAl: announces Dots xAI: buys dot . com and redirects it straight to Grok 😅 This is marketing 101 #DevDay

超酷！Romain刚刚在OpenAI伦敦的DevDay现场，在Cursor里用o1 -MINI大约2分钟捏了一个应用，控制无人机在舞台上飞行，表演后空翻 #openai #openaio1 #DevDay

hello it's me, oathbound orin. 1v1 community duels for the next 3 hours, #TeamLexa wearers first up, post for a FIGHT!! 7-0 and will stay added for future #devthursdays

Sorry folks, have to bail early to grab some Imodium before the convenience store closes 😳😰. Thanks for coming to this #devday (have we found the name yet?). And sorry for the mid match interruptions #badtofu

Picked up a #DevDay @modretro @Nintendo #Gameboy (via @eBay). Built directly from @OpenAI #Codex ✅ CONFIRMED! - @OpenAI Cartridge works* on OG #GB & #GBC ✅ #Astra was great at deploying as well as explaining the nuances and history behind the many editions of GameBoy. * The Original 1989 4 tone screen suffered mainly since it was afterthought (and a surprise) that was able to run the cartridge. Quality could be greatly improved through better contrast in the design.

i think dot didn't work well here #devday

OpenAI #devday is on right now in San Francisco. Keynote is free to watch, the rest gets posted after: I am an ML engineer building in AI and I want to know who else is here. What are you building this month?

Ultrafast 8x faster at 6x the price? Are you kidding me? 6x the price? Pro 500$ at 25x ? Is this a joke? We had 20x for 200$ until 1 hour ago... This is so bad it deserves a hashtag #openaidevday #devday

🕹️ #Multiplayer #DevDay @modretro 🎮 Used @OpenAI #Codex with the ModRetro #PlugIn to handle link cable communication and build a top-down, two-player paintball game with a larger, wrapping field and a mini-map. Opponents stay hidden until they fire, revealing their position. Like all things multiplayer, it was harder to test and debug, but Codex iterated through it all pretty smoothly. 🙏 @pvncher & team for such a solid plugin! #prototyping #AI @nintendo #gameboy

😂笑死了！Sam Altman 在 DevDay 现场喊麦 Tibo！ 这是这场DevDay最精彩的部分了吧！ #SamAltman #Tibo #DevDay #OpenAI #Dots

ROM on Consumer Cartridge CONFIRMED! A @modretro in #DeveloperMode (via @OpenAI #DevDay KEY) can flash ROM on a store bought Modretro consumer cartridge {RIP Buck ROM - saving wasn't possible} The PCBs aren't the same, but similar enough to allow the delightful #Codex #PlugIn that @pvncher & team whipped up (for some of coolest SWAG I've seen at a conference!) ⚡🕹️🧩 It was even backwards compatible with the OG #GBC [prototype was just seeing if I could fit @Adobe Photoshop on a Gameboy screen size] @gamestop #ASTRA #Chromatic

CRAZY: OpenAI’s agent just gave EVERYONE in the #DevDay audience $500 in credits! I think that is $500,000 total. WATCH this video for the LIVE audience reaction 🎉🎉🎉
