Diogo Almeida
Diogo Almeida is the co-founder and CEO of TypeSafe AI, a frontier AI lab building machine-native, composable AI for software systems. He previously worked as a Member of Technical Staff at OpenAI from 2020 to 2024, where he co-invented RLHF and InstructGPT, the methods that led to ChatGPT and GPT-4. Earlier in his career, he was a researcher at Google Brain and held data science and engineering roles at Enlitic and Amazon.
“She just basically saw that I was like this person who really didn't fit into the research community and then adopted me and showed me like it got me to meet all the AI people.”

“Where the fuck is all the automation?... AI is so unbelievably smart. And yet, so not that I hate on chatbots or coding agents. I love them myself. But it's like so useless at all other stuff. And it's tragic.”

Source→“Incredible way to describe what they're doing. Like it makes software on the fly.”

Source→“He co-authored the InstructGPT paper, the research that turned GPT into ChatGPT, and he spent the next two years in stealth building its opposite.”
Source→“Jev represents a new architecture explicitly built to separate judgment from generation, pricing decisions far below generative inference and eliminating output-token costs entirely.”

Source→“This week, the company released a new transformer-based model, Jev, that is not a large language model (LLM).”
Source→“Diogo Almeida, an OpenAI RLHF pioneer, built TypeSafe AI's Jev model specifically because 'it doesn't output text, but instead produces probabilities, or what the company calls calibrated decisions.'”
