Telnyx: decision-flash and Uprelic: strom, compared on what they decide, where they run, what they cost and what their publishers report.

| Summary | Telnyx's hosted decision models, in beta on Telnyx Inference. One request carries shared state and up to 64 typed questions (choice, yes/no noul, ordered score) and returns a probability per option, with no generated text, on a TypeSafe-compatible /v1/systemone route. | Uprelic's hosted decision API, run on GPUs in Paris. Answers noul, choice and score questions about text, JSON and up to 8 images, with a probability for every option and no generated text, on the same request shape as Jev. No weights; base model and size not disclosed. |

Figures are from each model’s manifest; accuracy and latency are what the publishers report, on their own suites and hardware. Add a third model.
decision-flash is from Telnyx and strom from Uprelic. Both are only available as a hosted API. Both answer choice, score, noul, classify and route questions.
Only strom publishes an accuracy figure (87.0% on JevBench public set (231 items), the maker's production run of Strom 1.0.7 on 1 Oct 2026 (Open-Jev harness format)); decision-flash does not, so there is no comparison to make without your own test.
decision-flash: $0.035 / $0 per 1M. strom: $0.042 / $0 per 1M. Open weights cost nothing per call beyond your own hardware.
Neither: both are only served as hosted APIs.
