Turning the EHR into an intelligent, conversational partner is one of the hardest problems in clinical AI. The gap between a flashy demo and a production-grade clinical assistant is much wider than people think! Today we shipped Chart Chat! Check it out 👇

Surreal moment. We just announced our $243M Series C, co-led by @oakhcft & @a16z. The validation is nice, but as an engineer, my first thought was literally: "did I remember to enable DDoS protection last night?" bloomberg.com/news/articles/…

Had an amazing time with Ben and @labenz on the @CogRev_Podcast discussing LLMs & RL in healthcare. open.spotify.com/episode/3R4rTA…

Excellent keynote from @j_r_a_m at #AIMI25. LLMs are advancing rapidly, but realizing the benefits in real-world clinical settings is not guaranteed. Monitoring and evaluating AI tools at scale at large health systems is an exciting open problem for our industry.

This leap in performance is a testament to the power of RFT. Exceptional work by our friends at @OpenAI in pioneering this new paradigm in fine-tuning!

Our RFT-tuned reasoning system listens to visit audio, integrates relevant EHR context, & recommends precise ICD-10 codes in real-time. This supports clinicians at the point-of-care, improving reimbursement integrity and reducing compliance risk.

Ambience's RFT-tuned model boosted ICD-10 coding accuracy 27% over expert clinicians—and it's now spotlighted in @OpenAIDevs' Reinforcement Fine-Tuning use case guide. Excited to see what the community builds with this powerful new customization technique: platform.openai.com/docs/guides/rf…

@FanNie1208 Excited to try this out for clinical use cases!

🚀 Excited to share that “#FactTest: Factuality Testing in Large Language Models with Finite-Sample and Distribution-Free Guarantees” has been accepted to #ICML25 ! 🎉 📄 Paper: arxiv.org/abs/2411.02603 💻 Code: github.com/fannie1208/Fac… 1/N

Love to see the research community building out new ways to eval LLMs on real-world clinical workflows. A missing gap in the field! hai.stanford.edu/news/medarena-… Great job @james_y_zou and team 👏

If you want to work on one of the most important problems in healthcare and AI — and do it in-office, with a team that’s all-in — we’d love to meet.

We’re hiring: - Head of Research - ML Researcher - ML Engineer

Over the last 3 years, we’ve quietly built one of the most capable clinical AI teams in the world — an unusual mix of top ML researchers, engineers, and practicing clinicians working side-by-side in SF. Our user base is growing exponentially — and we’re hiring. Thread👇

Thrilled to announce our enterprise expansion at Cleveland Clinic. In the coming weeks, we'll be onboarding thousands of new clinicians to the Ambience platform. 🚀 newsroom.clevelandclinic.org/2025/02/19/cle…
