Beyond the chatbot mirage: Why HCLS leaders are reframing AI as a search problem

Most enterprises now have a generative AI strategy, but the challenge has shifted: how do we move from impressive demos to production systems that scale safely and meaningfully? In a regulated industry like Healthcare & Life Sciences (HCLS), the future of AI isn’t about building bigger models, it’s about smarter retrieval. 

The core takeaway from our panel with leaders from Novo Nordisk, Alkermes, and Vespa.ai is that we must increase trust with purpose-built retrieval systems. By controlling the data and providing the right context, we reduce hallucinations and ensure AI outputs are grounded in factual, institutional data. 

From chatbots to context engines

Every RAG (Retrieval-Augmented Generation) solution must balance three competing priorities: cost, performance, and quality. 

To succeed at scale, leaders must move beyond the chatbot mindset and design context engines. Context is the additional information a model needs to answer questions it hasn't seen during training. Whether it's internal institutional data or external research, the accuracy of a response depends on how well a system can search, retrieve, rank, and contextualize that information. 

Vertical impact: Turning search into intelligence

1. R&D: Drug discovery as a search challenge

Drug discovery is effectively an exercise in intelligent retrieval. With molecule and protein spaces spanning 10⁴⁰ to 10⁷⁰ combinations, a space larger than the atoms in the known universe, the task is to find a needle in a haystack.

• Key takeaway: We’ve shifted from building bigger knowledge graphs to building smarter search spaces using tensor embeddings to represent relationships between molecules, proteins, and diseases. 

2. Commercial: Scaling without losing trust

Anubhav Srivastava, AI Engineering Head for Commercial at Novo Nordisk, reframed commercial AI is a human-centric search task. Field reps and medical liaisons don’t need another chatbot. They need fast retrieval from an avalanche of multifarious brand documents. 

• Key takeaway: We must manage the three Ps of AI: Perception, People, and Performance. To these, we add a fourth: Personalization. Retrieval must adapt to the persona, whether it’s a scientist, a rep, or a payer. 

3. Healthcare & payers: Context is everything

In healthcare, the richest insights live at the intersection of structured claims, unstructured notes, and imaging data. For payers, the challenge is often a lack of retrievable context, which leads to generic care plans. 

• Key takeaway: Payers should mimic consumer models like Netflix or Spotify. By using retrieval to compare members with "look-alike" patients, care plans can become dynamic "learning loops" rather than static processes. 

Context is the currency

You can’t trust a model to know everything, you must retrieve the right context every time. Whether it is searching molecular space, patient cohorts, or member journeys, the future of HCLS AI is built on smarter retrieval systems. 

Design for retrieval first, and intelligence will follow.
