The experts are watching how we build

Shout out to Matt Payne at Width.ai. Great article on using dynamic shot prompting for each turn of the conversation to optimize the bot’s ability to flow with the conversation and give ideal responses. Brilliant technique here. We have a lot to learn from people in the field who have been developing solutions for customers since GPT2!

Layout Schema Driven Prompt Tuning

Utilizes a layout understanding model to dynamically adjust prompt rules based on recognized document formats and page types. Provides field-focused guidance to help the LLM link complex entities. By tailoring rulesets to relevant pages and skipping unnecessary ones, the system minimizes hallucinations and improves data recognition efficiency.

Hierarchical Relationship Extraction using Program Synthesis

Our SOTA program synthesis system for doc processing allows us to build a machine learning algorithm to learn key -> value attribution rules (entity linking) through a trained relationship on common patient doc layouts. Creates understanding of key -> value distance, entity mapping with boxes and tables, and character size relationships.

Are your custom healthcare RAG solutions set up to integrate into our existing systems?

Yes! Pretty much all of the RAG systems we build are used as integrations into existing systems or products. We build all of our frameworks as deployable APIs so they can easily be added to a SaaS UI, internal workflow, or conversational system.

Does custom RAG development take long?

There are a ton of variables that go into the length of time it takes to go from zero to hero when building truly intelligent RAG systems. Things like:

- What is the scope level (MVP vs Prod)? Every POC we build is scoped to 27 days.
- Are we integrating external tools and APIs into the workflow?
- How complex is our knowledgebase and tool calling requirements?
- Are we building this as agentic RAG or simple pass RAG?
- Do we have any speed or infrastructure requirements?

Completely drive the timeline. We scope everything ahead of time so you know exactly what the plan is and how we will get there.  

How are you a different healthcare RAG development company?

We're not a general software firm where ai is branch of what we do, its all we do. We've worked with healthcare companies building RAG, chatbots, document processing solutions, and automations since 2022 and have helped multiple companies raise large investment rounds with our SOTA work.
