MedGemma, Missing Patients and the Myth of “Open” Health AI

AI‑generated patient summary and draft report over a crowded Indian hospital waiting area, highlighting MedGemma’s role in the consultation.
MedGemma is framed as an invisible assistant in the consultation room, even though its model card still classifies it as a research starting point.

Why this film, and why now?

Inside Google, MedGemma is not a side quest. The model family sits on top of Google’s Gemma 3 architecture and targets medical text and image comprehension. Both the technical report and the model card frame MedGemma as a foundation model for developers and researchers, intended to accelerate health‑AI applications – not as a drop‑in diagnostic engine.deepmind+4

Meanwhile, India’s digital story has moved from “fast‑growing market” to “co‑author of digital public infrastructure”: UPI for payments, ONDC for commerce, the Ayushman Bharat Digital Mission for health records. Google understandably wants MedGemma to sit in that slipstream – as the AI engine that plugs into India’s “open ecosystem standards” and underpins a new generation of health tools.

This film lands precisely at that intersection. It wraps a developer‑oriented model in the language of national potential, clinical empathy, and open standards. When you’ve been tracking Google’s broader narrative shifts in advertising and AI, the pattern feels familiar: infrastructure plus emotion, with the business model humming quietly in the background.

The question is not whether the storytelling is clever – it clearly is. The real issue is what this move does to how marketers frame AI in critical sectors like healthcare, and what gets smoothed over in the process.

1. From case film to infrastructure strategy

The film opens, not with a product, but with a claim about identity:

India, not MedGemma, takes the lead role. The “villain” is cast at system scale:

  • A “large and diverse population” that’s both challenge and strength.
  • AIIMS Delhi seeing 15,000 patients a day, with clinicians trying to skim records, labs, and images in minutes.
  • A skewed doctor–patient ratio, with clinicians concentrated in cities and patients “somewhere very far away in India.”

The film presents MedGemma as seamless health plumbing, but each layer in this stack needs separate validation – and the base model hasn’t passed clinical clearance yet.
  • An AI assistant pre‑collecting patient information before the consult.
  • A model doing image classification, interpretation, and report generation.
  • A “collaborating centre” at AIIMS convening universities, industry, and startups “specifically directed at AI in healthcare.”

The vocabulary leans hard on infrastructure:

  • “Multiple centres across the country.”
  • “Open ecosystem standards for industries such as payments, health.”
  • “Innovation at scale.”

What the fine print actually says

2. Who owns “open” in open medical AI?

One of the most seductive lines in the film sounds innocuous:

That phrase – “open models, hosted in your secure environment” – hits three anxieties in one breath:

  • Fear of black‑box AI.
  • Fear of sending sensitive data to foreign clouds.
  • Fear of being locked into a single vendor’s stack.

The trouble is that “open” is doing more rhetorical work here than technical.

Open… inside a very specific stack

Clinicians and partners control workflows and apps, but Google still owns the weights, architecture, data and safety policies that define what “open” really means.

In practice, “open” means:

  • Developers can download weights.
  • Teams can fine‑tune those weights.
  • Hospitals or partners can host the models in their own infrastructure.

At the same time, Google controls:

  • The core architecture and its evolution.
  • The original training data blend and its blind spots.
  • The safety frameworks, evaluation protocols and red‑teaming methodology.
  • The roadmap: new versions, deprecations, ecosystem tooling.

Plenty of other foundation models work this way, so none of this is unusual. The issue lies in how easily viewers can conflate:

  • “Open models” in the film – which, in the context of India’s DPI story, sounds suspiciously like public, neutral infrastructure.
  • “Open‑weight models under a private vendor’s technical and governance umbrella” in reality.

Why it matters to get “open” right

You can still align with public infrastructure, but with more nuance:

  • “We’re releasing open‑weight models that plug into India’s open health standards, under transparent terms of use.”
  • “Hospitals can run these models in their own environments, under their security policies, instead of sending data to our cloud by default.”
  • “Here’s the part of the stack we control (architecture, pre‑training, safety frameworks), and here’s what partners control (fine‑tuning, deployment, clinical validation).”

3. The disappearing patient

Scrub through the script, though, and patients mostly show up in three ways:

  • As mass: 15,000 people a day, long queues, “somewhere very far away in India.”
  • As inputs: a patient answering an AI assistant’s questions; radiology images flowing into a classifier; reports appearing.
  • As abstractions: “the patient” as the end point of innovation, invoked but rarely allowed to speak.

A real patient voice never appears. Nobody asks how it feels to be screened by an assistant, or whether patients want AI in this part of the journey at all. We don’t see what happens when an AI‑drafted report clashes with a clinician’s judgement, or how that conflict gets resolved.

The core relationship on screen looks like this:

  • Google ↔ AIIMS (and, by extension, other elite institutions).

The film frames patients as numbers, queues and inputs. This is the inverse of what real AI governance needs: patients at the table when decisions about their data, their care and their AI are being made.

Patients sit behind them as justification, not as stakeholders in the design or deployment of the system.

Documentation quietly reinforces this hierarchy

  • Patient advisory councils or community input into evaluation.
  • Consent models for downstream tools powered by MedGemma.
  • Rights to explanation, challenge, or opting out of AI‑mediated workflows.

From the documentation’s point of view, the patient appears as a risk vector and an eventual beneficiary, not as a decision‑maker. The film inherits that blind spot and acts it out visually.

For marketers, this is the place to resist the easy version of the brief. When a campaign claims “AI is a great leveller”, the storytelling needs to do more than pan across a waiting room. Let patients speak. Let them ask uncomfortable questions. Let them say no.

Challenges and ethical considerations you can’t cut around

The film does at least gesture towards risk. It mentions de‑identified datasets, secure environments, and repeatedly calls MedGemma an “assistant”. But if you plan to borrow this narrative shape in your own AI work, three issues deserve more airtime than a single line of VO.

Data privacy and security: who sees what, where?

“Secure environments” and “de‑identified anonymised medical datasets” sound reassuring in a script (film link). In practice, privacy and security in medical AI involve several layers, as even the MedGemma Technical Report and its full text make clear when they discuss data sources, de‑identification and contamination risks.

  • Training data provenance: De‑identification reduces risk, but doesn’t erase it. Researchers have demonstrated re‑identification attacks on medical images and clinical text, especially when datasets are combined or linked.
  • Access control in deployment: A “secure environment” at a well‑funded academic medical centre looks very different to a server room in a district hospital. The same model can carry different risks depending on who runs it and how they log, audit and restrict access.
  • Secondary use creep: Once you have AI‑ready pipelines, data becomes attractive for all kinds of secondary use – analytics, insurance risk scoring, targeted outreach. If marketing stays silent on that, audiences may assume consent where none exists.

For any AI marketed as infrastructure, the story needs to show where data flows, who controls it and what protections exist. That needs to show up in the narrative itself – ideally through clinicians and patients, not just product leads and legal boilerplate.

Algorithmic bias: whose body is the model trained on?

Human oversight: assistant, or quiet authority?

The problem is that “human in the loop” can mean very different things in real workflows:

So the real questions for anyone marketing an AI assistant look more like these:

  • How much time does a clinician actually have to disagree with the model in a typical session?
  • What training do they receive on when and how to override its suggestions?
  • Does the institutional culture back them up when they push back against an AI‑generated output?

A responsible 2026‑era narrative doesn’t pretend this tension doesn’t exist. Instead it sounds more like:

So what should marketers do differently?

If you’re a marketer, strategist, or UX writer working around AI in high‑stakes domains, there’s a lot to learn from this film – and just as much to resist.

1. Treat the model card as part of your script

Before you write a single line of film dialogue or landing‑page copy, treat your model card and technical report as non‑negotiable sources, starting with documents like the MedGemma Technical Report and its full‑text version.

Then:

  • Pull key constraints into the narrative itself. What the model cannot do is as important as what it can.
  • Let characters voice those limits – a doctor saying, “This doesn’t replace our judgement; it gives us a second lens,” will travel further than a legal disclaimer.
  • Show how those constraints play out in practice: approvals, audits, fallback pathways when the model fails.

This isn’t just good ethics. In a landscape where AI promises are cheap, grounded constraints are a competitive advantage.

2. Be precise about “open”

When a model is open‑weight but governed by a proprietary licence, say that. When training relies partly on proprietary data, say that as well.

You can still align with public infrastructure, but with more nuance:

  • “We’re releasing open‑weight models that plug into India’s open health standards, under transparent terms of use.”
  • “Hospitals can run these models in their own environments, under their security policies, instead of sending data to our cloud by default.”
  • “Here’s the part of the stack we control (architecture, pre‑training, safety frameworks), and here’s what partners control (fine‑tuning, deployment, clinical validation).”

3. Put patients back at the centre – for real

If patients are the reason you say you’re doing this, they need to be more than B‑roll. That means:

  • Letting them speak about how AI‑enabled workflows actually feel.
  • Showing consent conversations, not just consultation footage.
  • Including moments where they opt out, or challenge decisions.

Beyond the story, bring patient involvement into the product process:

  • Establish patient advisory councils for health AI deployments.
  • Publish performance results across regions and demographics.
  • Provide clear, patient‑facing documentation and routes to contest AI‑influenced decisions.

A lot of my recent work on agentic AI journeys has focused on turning users from targets into participants (example here). In healthcare, patients are the ultimate “agents”. Campaigns that treat them as such will feel very different to stories where they remain faceless queues in a corridor.

The opportunity – and the risk – in MedGemma‑style stories

For marketers, the temptation is to copy the template: sweeping national stakes, humble but brilliant protagonists, AI as invisible helper.
A smarter move is to treat it as a starting point – and then push past it.

Because the next wave of AI health stories will be judged not just on their cinematography, but on whether they:

  • Accurately reflect model capabilities and limits.
  • Are honest about who owns what in “open” AI.
  • Treat patients as participants in governance, not statistics in a deck.
  • Address privacy, bias, and human oversight as design problems, not boilerplate.
