Testing TypeSafe Jev, Mistral and Gemini for local event validation
A use-case study comparing Jev, Mistral Small 4, and Gemini 3.5 Flash-Lite on rejecting unsuitable local-event listings, with individually tuned prompts, accuracy, response times, and costs.

Highlights
- Jev matched 48 of 50 expected decisions, ahead of Gemini 3.5 Flash-Lite at 43 and Mistral Small 4 at 42.
- Jev rejected none of the 13 expected-valid events; Mistral rejected 5 and Gemini 1.
- On the 21-record timing run, Jev's median response was 0.58s and total cost $0.000904 versus Gemini's 3.44s and $0.052421.
- Cost per 1,000 decisions at list prices: Jev $0.043, Mistral $0.370, Gemini $2.496.
- Prompts were tuned per provider across 132 cases, including 32 purpose-written cases covering policy boundaries.
Watch out
A use-case study by an events company rather than a general model ranking: samples are retained rejection cases, expected decisions were assistant-written, and the 21-record timing set was not a blind test.

A self-hosted implementation of TypeSafe's Jev System One API powered by the 400M-parameter GLiFormer encoder: it serves choice, score, and noul and drops into the official typesafe-sdk via TYPESAFE_BASE_URL, but trails Jev on reasoning-heavy tasks.

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

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!
