Epic Sepsis Model vs Luminare (2026)
The most useful disagreement in this category, because the two vendors do not accept the same problem statement. The Epic Sepsis Model is a prediction problem answered with a proprietary score running inside the record system at hundreds of hospitals, and the external literature on it is the largest and least flattering of any model in this index. Luminare's founding argument is that prediction was never the constraint: hospitals already know which patients are at risk and fail at the intervention, the bundle and the workflow that follow. That argument is published and defensible, and if your hospital already has a screening score firing into a ward that ignores it, Luminare is aimed at your actual failure. It is also the less evidenced of the two, with no controlled outcome evaluation of the product located, which is uncomfortable for a vendor whose whole pitch is that outcomes are what matter.
- It argues that better prediction is not the problem, and builds around intervention and workflow instead, which is a coherent response to a category where the most validated model in the index still underperformed in the field.
- The founding position is published and argued in a peer reviewed review article rather than asserted in marketing, so a buyer can engage with the reasoning rather than the claim.
- For a hospital that has already deployed a screening model and seen no outcome change, this addresses the actual failure, which is what happens after the alert fires.
- It is already running at hundreds of hospitals inside the record system, with no additional procurement, integration or data processor, and its scores are visible in the workflow clinicians already use.
- The widest deployment of any product in this index means the published external evidence about it, favourable and unfavourable, is more extensive than for any alternative.
- The privacy and contracting position is structurally simplest, governed by the existing record system agreement with no third party involved.

Side by Side
Each record in one paragraph
Written to be quoted whole. Each paragraph states what the AI Health Index verified about the vendor, with the caveats attached. Generated from this pair’s live capability grades, so it moves when a grade moves.
The AI Health Index awards Epic Sepsis Model its top capability grade on Clinical and Operational Evidence, EHR and Interoperability Depth and Setting and Specialty Coverage. Set against Luminare, Epic Sepsis Model grades higher on several axes, including Model Supply Chain Disclosure, Clinical and Operational Evidence and AI Safety and PHI Stewardship. Its thinnest published disclosure sits on Model and Technology Transparency and AI Liability and Recourse. Grades reflect evidence the AI Health Index could verify at the last review, so a low grade records disclosure the vendor has not published rather than a capability it has been shown to lack.

Questions buyers ask
Should we choose Epic Sepsis Model or Luminare?
On the axes where the AI Health Index separates them, Epic Sepsis Model grades higher on several axes, including Model Supply Chain Disclosure, Clinical and Operational Evidence and AI Safety and PHI Stewardship, and Luminare grades higher on several axes, including Autonomy and Oversight Model, Model and Technology Transparency and AI Liability and Recourse. Epic Sepsis Model leads on the greater share of scored axes, but the split means the decision turns on which constraint is binding rather than on an overall winner.
Where do Epic Sepsis Model and Luminare differ most?
The widest separation the AI Health Index records between Epic Sepsis Model and Luminare is on Clinical and Operational Evidence, where Epic Sepsis Model grades A and Luminare grades C. That axis sits in the AI Capability group, so it should carry the most weight for a buyer whose binding constraint is how much of the work the model itself is trusted to do.
Where do Epic Sepsis Model and Luminare grade the same?
The AI Health Index grades Epic Sepsis Model and Luminare the same on several axes, including AI Centrality, Security Certifications and Trust Center and FDA and Regulatory Status. Neither holds an advantage the index can evidence on those axes, so they should not carry weight in a selection between these two.
What have Epic Sepsis Model and Luminare not disclosed?
At the last review, at least one of Epic Sepsis Model and Luminare published thin or absent detail on Model and Technology Transparency and AI Liability and Recourse. The AI Health Index treats an absent disclosure as a gap in the public record rather than a failure of the product, so these are the axes to get in writing during diligence instead of inferring from the grade.

Neither product resolves the alert burden problem on its own. The Epic Sepsis Model has been externally validated more than any other model in this index and the best known of those validations reported both missed cases and a substantial alert burden, and Epic publishes no model description or subgroup analysis.
Luminare's argument that workflow rather than prediction is the constraint is supported by a review article its own chief executive co authored, which is a stated position rather than independent evidence, and no controlled outcome evaluation of the product itself was located. Neither publishes pricing.
