Simon Willison 发布 llm-typesafe 0.1a0，为 LLM 插件接入 TypeSafe AI 的 Jev 模型

22nd September 2026

I built this new plugin for LLM to add support for TypeSafe AI's new Jev model . Install it like this:

llm install llm-typesafe

Then set an API key ( get one here , the waitlist seems to move pretty fast):

llm keys set typesafe # Paste key

And now you can ask yes/no "noul" questions like this:

llm -m jev 'Please refund my last payment.' \ -s 'Does this message explicitly request a refund?'

Output:

{"type": "noul", "noul": 0.99}

Or choice questions like this:

cat message.txt | llm -m jev \ -s ' Which team should handle this message? If billing and technical issues both occur, choose billing. ' \ -o answer_type choice \ -o criteria ' { "billing":"Charges, invoices, payments, or refunds", "technical":"Problems installing or using the product", "other":"Neither category fits" } ' Or scoring questions like this:

cat report.txt | llm -m jev \ -s ' How reproducible is the problem described in this report? ' \ -o answer_type score \ -o criteria ' [ "No reproduction instructions", "Some instructions, but important steps are missing", "Complete steps with expected and actual results" ] ' See the README for more details.
