Y Hacker News 1w neutral decision / modelsOllaya – Ollama for open-source, Jev-style decision modelsI am fairly confident if Jev-style decision models are seen as prominent (which, they seem to be), Ollama will support them. Surprised the team hasn't implemented this already. I am fairly confident if Jev-style decision models are seen as prominent (which, they seem to be), Ollama will support them.

Y Hacker News 1w neutral decision / modelsOllaya – Ollama for open-source, Jev-style decision modelsAre there many models that are comparable to Jev for generic decision making? Smarter move if you have an eval set is to just train a classifier and call it a day. Are there many models that are comparable to Jev for generic decision making?

Y Hacker News 1w neutral builtJevmem – automatic project memory for Claude Code, built on JevI really don't undertstand the jev-hype. Just start a cheap chinese agent in a context where it has only one tool, and JSON-schema constrain that toolcall to the response shape you want. Prompt the agent to make only one tool call and not speak. Done. I really don't undertstand the jev-hype.

Y Hacker News 1w neutral decision / modelsJevmem – automatic project memory for Claude Code, built on JevAh, well that makes a bit more sense. Admittedly I haven’t really looked into Jev and thought it was an open decision model rather than a proprietary product from TypeSafe. Ah, well that makes a bit more sense.

I haven't used Jev yet so this should be interesting. I'd be interested to see if any Deciduous users have opinions, too.

Y Hacker News 1w neutral decision / modelsJevmem – automatic project memory for Claude Code, built on Jevjevmem watches Claude Code, Cursor & Codex chats and keeps a JEVMEM.md in your repo up to date. After each message, Jev (TypeSafe) decides whether anything is worth remembering — a decision, a bug, a change of mind — and writes the keepers to that file. Reversed decisions get marked superseded. Install: npm i -g jevmem… jevmem watches Claude Code, Cursor & Codex chats and keeps a JEVMEM.md in your repo up to date. After each message, Jev (TypeSafe) decides whether anything is worth remembering — a decision, a bug, a change of mind — and writes the keepers to that file. Reversed decisions get marked superseded. Install: npm i -g jevmem (needs a TypeSafe API key) Held-out check on 66 messages (23 Sep 2026) vs six frontier LLMs: save/skip 98.5% (tied with Astra); save+correct kind 95.5% (Astra 98.5%, Opus 97.0%); changes of mind 5/5; median 0.30s via Jev API (~0.6s end-to-end) vs 2.8–4.3s for the LLMs; cost $0.000127/decision. Single run by me — treat 1–2 message swings as noise. Limits: early v0.4; fully automatic only in Claude Code today (Cursor/Codex via agent/MCP); messages go to the TypeSafe API with secrets stripped; if the API is down it skips.view source ↗
