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!

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?"

Had an amazing time with Ben and @labenz on the @CogRev_Podcast discussing LLMs & RL in healthcare.

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.

[Brendan Fortuner @bfortuner]

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!

[Brendan Fortuner @bfortuner]

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: https://t.co/Acf4GPF5CV

[Brendan Fortuner @bfortuner]

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.

[Brendan Fortuner @bfortuner]

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

[Brendan Fortuner @bfortuner]

Love to see the research community building out new ways to eval LLMs on real-world clinical workflows. A missing gap in the field!
