Dimitris Papadopoulos: biodecision and Telnyx: decision-flash, compared on what they decide, where they run, what they cost and what their publishers report.
| Property | lighteternal/biodecision | telnyx/decision-flash |
|---|---|---|
| Summary | A 4B biomedical decision model by Dimitris Papadopoulos: Qwen3.5-4B tuned with Together AI's Tev1 recipe on 1.75M pharma, clinical-trial and literature decisions. One forward pass gives a temperature-scaled probability per option. Research use only. | 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. |

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.
biodecision is from Dimitris Papadopoulos and decision-flash from Telnyx. biodecision has open weights you can download and run; decision-flash is only available as a hosted API. Both answer choice, score, noul and classify questions. Only decision-flash answers route. biodecision is licensed other; decision-flash, proprietary.
Only biodecision publishes an accuracy figure (75.3% on BioDecision v2 held-out test set (63,432 overlap-screened decisions from public biomedical benchmarks; the maker's own split)); decision-flash does not, so there is no comparison to make without your own test.
biodecision: Free (open weights). decision-flash: $0.035 / $0 per 1M. Open weights cost nothing per call beyond your own hardware.
biodecision yes — systemone pull lighteternal/biodecision downloads its weights. The other is only served as a hosted API.
