aetherAI vs Modella AI (2026)
Two computational pathology companies at different points on the regulatory map and at different layers. aetherAI runs a clinical platform spanning anatomical pathology and haematology, hosting third party algorithms alongside its own, and it holds both a United States clearance and European certification for its image management platform. Modella builds generative and agentic tooling on pathology foundation models, including a conversational co pilot over the slide, which reaches questions nobody wrote a detector for. A clinical laboratory signing out diagnoses needs the platform and the cleared components. A research group exploring what foundation models can do with a slide archive wants the co pilot, and should be clear with itself that using it to inform a diagnosis is a decision the laboratory owns rather than one a regulator reviewed.
- It spans anatomical pathology and haematology rather than one domain, with training scale disclosed for the haematology product.
- Its image management platform secured both a United States clearance and European certification in 2026, a genuine dual market position.
- The platform hosts diagnostic algorithms rather than only running its own, so a laboratory gets infrastructure and applications together.
- It builds generative and agentic tooling on pathology foundation models, including a conversational co pilot over the slide.
- Foundation models reach tasks nobody wrote a specific algorithm for, which is where the field is heading.
- For a research or academic department, a general reasoning layer is more useful than a fixed set of detectors.
This comparison is published by AI Health Index, an independent research platform that compares healthcare AI vendors objectively. aetherAI and Modella AI are each graded against the same capability taxonomy, from each vendor's own public materials and the regulatory record, under the AI Health Index verification standard.

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 records no top capability grade for aetherAI on any axis it scores. Set against Modella AI, aetherAI grades higher on Security Certifications and Trust Center, FDA and Regulatory Status and EHR and Interoperability Depth. Its thinnest published disclosure sits on Model Supply Chain Disclosure. 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.

The AI Health Index awards Modella AI its top capability grade on AI Centrality and Model and Technology Transparency. Set against aetherAI, Modella AI grades higher on AI Centrality, Model and Technology Transparency and AI Liability and Recourse. Its thinnest published disclosure sits on Model Supply Chain Disclosure. 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 aetherAI or Modella AI?
On the axes where the AI Health Index separates them, aetherAI grades higher on Security Certifications and Trust Center, FDA and Regulatory Status and EHR and Interoperability Depth, and Modella AI grades higher on AI Centrality, Model and Technology Transparency and AI Liability and Recourse. Neither leads on the greater share of scored axes, so the decision turns on which constraint is binding rather than on an overall winner.
Where do aetherAI and Modella AI differ most?
The widest separation the AI Health Index records between aetherAI and Modella AI is on Model and Technology Transparency, where aetherAI grades C and Modella AI grades A. 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 aetherAI and Modella AI grade the same?
The AI Health Index grades aetherAI and Modella AI the same on several axes, including Autonomy and Oversight Model, Model Supply Chain Disclosure and Clinical and Operational Evidence. 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 aetherAI and Modella AI not disclosed?
At the last review, at least one of aetherAI and Modella AI published thin or absent detail on Model Supply Chain Disclosure. 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.

A pathology co pilot built on foundation models is not a cleared diagnostic, so a laboratory using it to inform a diagnosis is making that decision itself rather than relying on something a regulator reviewed, and that distinction should not be blurred by comparing it against cleared products. aetherAI publishes no health privacy statement, business associate terms, hosting detail or subgroup analysis. Neither publishes pricing, and neither imposes a published performance requirement on third party algorithms it distributes or on the tasks the co pilot is asked to perform.
