ModelSpec is an analysis of alternatives for AI models: it decides which models fit a job from your requirements, sourced benchmarks and real cost, and shows its work.

Regulated data on a budget

Find the cheapest offering with the data-handling commitments regulated workloads need.

Worked example as of 2026-09-23, from the public data image.

HIPAA-ready offerings; cheapest first, quality kept.

Requirements

offering.data.trains_on_customer_data = No: Customer prompts and outputs must not be available for model training.
offering.data.zero_retention = Yes: The provider must offer a mode that stores neither prompts nor outputs.
offering.attestation.baa = Yes: The provider must offer a HIPAA business associate agreement for the service.

Preferences

-offering.cost_per_task: Prefer the lower task cost after the compliance gates pass.
chat_preference: Keep a quality signal so a cheap but poor assistant does not win on cost alone.

probability bands: a model joins the leader when P(its score >= the leader's) >= 0.25 under the score posteriors; a weighted capability with an 80% interval wider than 2.8 is not enough evidence

Tie-breakers describe members of the tie. They do not establish a winner.

probability bands: a model joins the leader when P(its score >= the leader's) >= 0.25 under the score posteriors; a weighted capability with an 80% interval wider than 2.8 is not enough evidence

Score and score interval use the objective's dimensionless normalised units. Cost per task is for the engine-selected offering and the applied spec's task size. When task size is omitted, the engine uses its documented default. P(best) is the engine probability. Unavailable means the engine did not return a value. Thin evidence is undetermined and is not a recommendation.

What this template teaches

The gates are the same as the other tiers; only the ranking moves toward cost.

The live board uses current data. Its answer can change as evidence changes.
