FINIO MODEL / EXPERIMENTAL

A financial model.
Built to be
measured.

Market data in. Probability estimates out.

Finio estimates the probability of a positive five-trading-day return for public equities. Successful API responses include a model version, as-of date and creation timestamp. Availability depends on the model service.

01 / THE IDEA

An explanation is useful.
A prediction is measurable.

General AI can explain a market move. Finio produces a structured number that can be checked against what happens next.

Market data becomes a probability estimate. A successful response can be inspected below. This page does not resolve outcomes or establish model performance.

02 / MODEL EVIDENCE

Don’t take our word for it.
Measure the model.

EXPERIMENTAL

Historical testing has not yet demonstrated a meaningful predictive edge. Historical evaluation and prospective outcomes are separate records. The model remains experimental.

A / HISTORICAL EVALUATION

What we know so far.

finio-model-v0.1 is a shared cross-asset classifier with a 5-trading-day horizon. Training: 314,234 samples across 295 securities, Jan 2022 – Jun 2026. Held out: 23,774 samples, Jul 2026 – Oct 2026. The dataset contains 299 securities.

Held-out accuracy: 49.84%; momentum accuracy: 49.16%. Brier: 0.251623; constant baseline Brier: 0.251618. Lower Brier is better; the model is slightly worse than the constant baseline. These results do not establish meaningful predictive edge. Figures supplied by Finio; evaluation artifacts are not hosted in this website repository.

B / LIVE · PROSPECTIVE PREDICTIONS

Inspect the response.

Successful responses include a unique ID, creation timestamp, model version, as-of date, probability, reference price and status.

The response fields can identify a prediction. This checkout does not contain the production ledger or an outcome resolver, so their operation cannot be verified here.
