Building @AbridgeHQ + random musings at intersection of Warp records, late 90s skateboarding, Vincent Van Duysen, and cardiology.

[Shiv Rao, MD @ShivdevRao]

Our thesis at @AbridgeHQ has always been simple: the best technology in healthcare should help the technology disappear.

This is our opportunity to use AI to actually rethink and redesign the system.

At @AbridgeHQ, it is a privilege to serve Veterans and the clinicians who care for them.

Landed in Chicago for #ScientificSessions26. Tomorrow at 9:15 AM CT in the Health Innovation Pavilion: one clinical problem from the room, one AI agent, built in real time. Come help me pick the problem! @AHAScience @AbridgeHQ #AHA26

My new piece in @NEJM_AI, "Vibe Coding versus Clinical Reality": the barrier to building has dropped, but the barrier to building safely hasn't. Physicians can now prototype; getting it safely to patients still takes engineers working alongside us.

We asked GPT-6 Astra to edit Qwen3.5-0.8B weights to improve math.
It directly changed only 0.016% of weights, fixing 0.8B's reasoning loops & improving math up to 6x and even instruction following 3x, without gradients or training.

We call this Weight-Space Programming: frontier LLMs can now natively read/write neural network weights! 🧵

The @AbridgeHQ Assistant is the AI assistant for healthcare.

Our vision is that every clinician has a team of agents figuring out all the things they want to know, helping them ask the right questions, leverage the right evidence, and improve patient care and outcomes.

Now in use at 300+ health systems.

[Abridge @AbridgeHQ]

“What’s changed since this patient’s last visit?”

Ask the Abridge Assistant. Explore the chart and clinical questions with available patient context and cited evidence.

The same chat supports medical calculators pre-filled with available patient data and draft documents, such as referral letters. Review the sources and calculator inputs; edit drafts before use.

Grateful to @NEJM_AI for having me on Grand Rounds. The barrier to building has dropped, but the barrier to building safely hasn't. Closing that gap is what we do every day at @AbridgeHQ.

[Shiv Rao, MD @ShivdevRao]

Excited to back @kevinweil and Warp Sciences 🚀

Kevin has been an awesome friend / advisor / investor of ours over the years. Excited to see him and @dpatil build in healthcare / life sciences 🙌.

[Kevin Weil 🇺🇸 @kevinweil]

💥 Introducing Warp Sciences, a new company applying AI and robotics to help the world develop new medicines faster.

We’ve raised a $215M Series A led by @lightspeedvp to bring frontier AI out of the browser and into the lab, and build scientific capacity here in America.

I co-founded Warp with my long-time friend @dpatil, FAIR co-founder @manohar_paluri, and drug hunter Sol Reisberg. The early team is full of incredible people like @bkspears9, who helped achieve Q>1 fusion at LLNL.

@CALonghurst @mandl @peteratmsr @seattlechildren @AskTeendoc @theNAMedicine @SharekPaul @pattifbrennan @UCSDHealth @UCSDMedSchool @UCSanDiego @atulbutte @drcynthiagyamfi love to see it, and well deserved!

[Shiv Rao, MD @ShivdevRao]

Abridge Assistant helps clinicians prepare, brings relevant information into the workflow, and gets the first draft done. Clinicians bring the judgment.

@noah_weiss @dolapo Awesome work, really stoked for this. Congrats Noah!

[Alex Ren @AlexFellowsFund]

Thought I’d share a personal story from before we invested in @AbridgeHQ:

I was taking my son to his annual check-up at Sutter Health.

When we got there, the doctor asked us if we’d be open to trying new AI tech that documents visits.

I asked for the name of the company and she told me it was Abridge.

My investor curiosity started kicking in, so I told her I was excited to try it.

She launched the app and started recording the entire check-up. During the meeting, she asked my son the typical playful questions like “Do you have 120 toes?” or “Is that a Dinosaur in your ear?”

But when we checked the EHR, everything had been pulled in w/ no mention of dinosaurs or extra toes - crazy.

Investor curiosity kicked in again so I asked her if the product was “sticky.”

She basically told me they couldn't live w/o Abridge.

At that point in time, I had heard about the company but hadn’t realized how impactful it’d become w/ frontline users. So as soon as I got home I started digging.

We did our research at the fund, made the connections, and eventually backed the company.

Thrilled to see them changing people’s lives.

@AbridgeHQ and UT REAL Health AI are partnering to expand access to Abridge’s clinician intelligence platform across the University of Texas System.

True technological transformation in healthcare requires trust, workflow integration, and scale. The UT System brings a vision for all three, and a commitment to implementing AI responsibly, with clinicians and patients at the center.

The partnership extends across a connected healthcare ecosystem: helping clinicians focus on care, supporting institutions as they learn from one another, and creating room for continued clinical and operational innovation. It is a privilege to partner systemwide.

That's a wrap for Abridge VP of Product Janie Lee on @MTSlive!

Key takeaways:

-- Abridge Assistant has been the fastest-growing product in Abridge history
-- Context-aware clinical intelligence—patient chart data is crucial for decision support
-- Clinician jobs are changing. The future of AI is supporting them
