NeuroLink
A Juspay TypeScript SDK that treats Jev as a third inference type beside generate and stream: providers declare which kinds they serve, and tryDecide returns typed boolean, choice, or score answers, null when no decision provider is set.

Highlights
- decide is declared per provider through an inferenceKinds field rather than inferred from behavior; of 40 unified providers, Jev alone serves decide.
- Every internal Jev caller fails open — tryDecide returns null on any failure — so with no key configured the library behaves exactly as before.
- Jev is used internally for model routing, context compaction, MCP tool selection, and RAG planning.
- Routing uses asymmetric confidence thresholds, upgrading at 0.3 and downgrading at 0.6, because a wrong downgrade costs more.
- A 64-model registry (7 providers, 132 aliases) backs metadata and context-window checks; Ollama, LM Studio, and llama.cpp run fully locally.
Quickstart
import { NeuroLink } from "@juspay/neurolink";
const pipe = new NeuroLink();
const decision = await pipe.tryDecide({
state: { ticket: "Refund request, $42, first occurrence" },
questions: {
autoApprove: { type: "boolean", instructions: "Approve without human review." },
},
});Watch out
MIT-licensed and not affiliated with TypeSafe AI; needs at least one provider API key or a local runtime, and Jev decisions require a TypeSafe key.

The case against Jev-scored compaction
This is a terrible compaction strategy that fundamentally doesn't understand how compaction and context management work. Seems like a lot of people are confused so let's break this down. 1. Compaction isn't a filter The role of compaction is to clean up history to keep the Show more
found the perfect use case for @typesafeai Jev: instant compaction in 2026, why is compaction still a summarization prompt? Jev can make it instant by scoring every tool call and dropping what’s irrelevant
Classifying rows in DuckDB
I made a DuckDB extension where you can use @typesafeai 's Jev to do quick classification of rows in any csv/parquet file or duckdb table about 10sec for 1k rows ~ better than using an LLM, way more ergonomic than a classifier game-changing for data analysis!

AI multiple choice, not essay writing
WTF is Jev by @typesafeai? Here’s the tl;dr ELI5: Think AI multiple choice, not AI essay writing. It doesn’t chat. It makes decisions your software can act on: “Spam or not?” “Which tool should this agent use?” “Does this need a human?” The exciting part: roughly 200x faster Show more
Screening agent actions with Jev
Tested TypeSafe’s Jev (no-text, probability-only model) as an AI agent safety monitor. Checking each action first worked well caught most attacks with almost no false blocks, and much faster than Gemini.
After co-inventing ChatGPT, I kept asking myself: why have superhuman chat models not led to AGI? I’ve spent the last 2 years in stealth building a new way to train models (RLCD), and a new type of frontier AI model that we are releasing today: Jev • 20-200x faster • 40-400x
