Hi there 👋

I am Federico, Senior ML Scientist at TogetherAI. I build agents (self-improving agents, data science agents, deep research agents). I previously was a Postdoctoral Researcher at Stanford University.

You can check out my website to know more about me, you can also follow/tag me on Twitter.

• 📚 Optimizing generative AI by backpropagating language model feedback (Nature 2025)
• 📚 Safety-Tuned LLaMAs: Lessons From Improving the Safety of Large Language Models that Follow Instructions (ICLR2024)
• 📚 A visual–language foundation model for pathology image analysis using medical Twitter (Nature Medicine 2023)
• 📚 Easily Accessible Text-to-Image Generation Amplifies Demographic Stereotypes at Large Scale (FAACT2023)
• 📚 When and Why Vision-Language Models Behave like Bags-Of-Words, and What to Do About It? (ICLR2023)
