Q: Can I run bekko-system-one or decision-flash locally?

bekko-system-one yes — systemone pull hotchpotch/bekko-system-one downloads its weights. The other is only served as a hosted API.

Yuichi Tateno (hotchpotch): bekko-system-one and Telnyx: decision-flash, compared on what they decide, where they run, what they cost and what their publishers report.

The short version

bekko-system-one has open weights you can download and run; decision-flash is only available as a hosted API.
Both answer choice, noul and score questions.
Only decision-flash answers classify and route.
bekko-system-one is licensed other; decision-flash, proprietary.

Property	hotchpotch/bekko-system-one	telnyx/decision-flash
Summary	Ultra-small English encoders (17M, 68M and 395M) fine-tuned from Ettin rerankers. Each answers choice, noul and score questions with a probability per candidate and no generated text. Experimental v0 by one developer; the weights have no licence assigned yet.	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.
