I am Fede, a Senior ML Scientist at TogetherAI. I am working on post-training in LLMs, mainly self-improving and self-evolving AI Agents.

My expertise spans AI, highlighted by technical contributions in prestigious venues such as ICML, ICLR and Nature Medicine, as well as recognized projects. I specialize in ML and LLM development, with notable features in Nature, Nature Machine Intelligence and in the Washington Post.

Work

I co-organized Agents4Science, the first AI-first scientific conference, featured in Science, Nature, MIT Technology Review, Science News, and international media including Chinese, Korean, Spanish, and Italian outlets.

I am the co-inventor of TextGrad, a library for autograd with textual feedback, FashionCLIP, pioneering fashion-oriented CLIP models, and CTMs, a library for topic modeling with Contextualized Embeddings.

My safety research has been adopted by Meta, OpenAI and Anthropic, while FashionCLIP serves as a backend for numerous fashion recommendation systems, accumulating 100 million downloads.

I frequently give talks about my work! In late 2025 I spoke at companies like Nvidia and Amazon, research institutions (e.g., I was recently invited by Stanford KIPAC and FBK) and conferences like MLOpsWorld and at various meetups.
