AT0M (Pienomial)
A private System One decision model meant to ship as a single self-contained Rust binary (CPU/Metal/CUDA); for now only a hosted evaluation endpoint, with published comparisons to Jev and Cloudflare Clef.
at0m.pienomial.com/Active
Show HN 2026-09-30; site on 2026-10-25 offers a v0 hosted evaluation endpoint and a waitlist; the self-hosted v1 Rust binary is 'to be released'. (checked 2026-10-25)
In The Jev ecosystem
Where it stands apart
- How is the main thing licensed? proprietary or closed source (5% of 21 others)
- How is it mainly sustained? company or startup with a free product (no revenue yet) (5% of 20 others)
- Can it run entirely on your own device or infrastructure, without the maker's servers? no, it needs the maker's servers (19% of 21 others)
- Which shared standard or format does it mainly build on? none of these (its own format or interface) (14% of 21 others)
- What is the main thing it ships? a runtime, server, proxy, or desktop app for running models (24% of 21 others)
- Where do the decisions run by default? a hosted API (24% of 21 others)
What it shares with most of the community
- Is it actively maintained? active (62% of 21 others)
- Do you need an account to use it? no account (86% of 21 others)

- Which question types does it handle? Jev's three: noul, choice, score (67% of 21 others)
- Can you use it without a TypeSafe account? yes, no TypeSafe account involved (62% of 21 others)

The public sources we read don't say:
