great first episode to a pretty unique podcast format. Katie Dill x Randy Hunt
Launch day! I'm so excited to share "The General Podcast," a true labor of love and almost a year in the making. 💥 It's a 'hostless' show that pairs founders, execs & creatives for fly-on-the-wall conversations on craft, curiosity & building (because maybe the world doesn’t…
very few companies create space for this type of polish work, and it shows
Before vs. After
hiring a video editor at OpenAI (contract) - help record/edit demos of new dev platform features (basically, our screen studio person) - show how to use image gen + sora - has good taste and a sense of what devs care about DM me if interested!
We've improved image generation in the API. Editing with faces, logos, and fine-grained details is now much higher fidelity with features preserved. 🔍 Edit specific objects, create marketing assets with your logo, or adjust facial expressions, poses, and outfits on people.

Remember reinforcement fine-tuning? We’ve been working away at it since last December, and it’s available today with OpenAI o4-mini! RFT uses chain-of-thought reasoning and task-specific grading to improve model performance—especially useful for complex domains. Take…
memory is now magic
Starting today, memory in ChatGPT can now reference all of your past chats to provide more personalized responses, drawing on your preferences and interests to make it even more helpful for writing, getting advice, learning, and beyond.
