mini-jev: structured decisions from frozen Qwen3-4B
JEV-STYLE TYPED DECISIONS WITHOUT TRAINING a new approach called mini-jev lets you extract structured decisions from a frozen Qwen3-4B without generating a single output token. how it works: → Turn each schema field into a lettered question → Read the logits for each option → Get the decision directly on closed enums, it matches grammar-constrained JSON accuracy. the speed gains are interesting to

Gmail-to-Revolut receipt matcher for 5,400+ emails
I hate receipts, so I built something that does them for me. Gmail in → @Revolut business ready receipts sent to your revolut mailbox. Every receipt found, matched to the right expense, filed. Even the Uber tip that comes separately. Powered by Jev by @typesafeai . 5,400+ emails in, costs pennies. Also, makes Revolut's "auto-matching" much more accurate by providing additional information in PDF f

On a big extraction job, a cheap local model with Jev as the judge replaces Claude Opus. Not matches it in a lab. Replaces it where Opus is impossible to pay for: 100,000 company websites cost us about $650 this way, against about $50,000 with Opus. https://t.co/WZ9lwG4sbW

Rent payment reconciliation with Jev fallback for uncertain matches
J'ai intégré JEV pour traiter le rapprochement entre les virements et les loyer pour surveiller qui paye quoi. Mais bizarrement dans mes tests, il est moins efficace que l'heuristique que j'avais déjà mis en place. Donc ce que j'ai fais, c'est que l'heuristique reste le premier passage et si elle n'est pas certaine, JEV passe derrière pour affiner. Sur la lecture des libellés non encore intégré da

Jev fits right into what we built Avalanche for, and I see myself using it in almost every workflow, often just as a smart if statement. It’s also available to use right now in Avalanche.

JEV is INSANE It read 6,030 ChatGPT answers to buyer questions about 1,005 YC companies and checked every company name in every answer. 37,636 verdicts. 9.1M tokens. 40 seconds. $0.38.

Text-row extraction benchmark: Jev vs Haiku 4.5
Probé Jev 1.13, de TypeSafe, contra Haiku 4.5 en una tarea concreta: sacar datos de filas de texto. Lo curioso de Jev es que no escribe nada. Solo responde preguntas cerradas con una probabilidad. En 19 filas que ninguno había visto, empataron: 16 de 19 filas enteras bien cada uno (84,2 %), aunque fallaron en filas distintas. Campo a campo ganó Haiku, 96,8 % frente a 90,5 %.
