37,636 verdicts on 6,030 buyer questions for 1,005 YC companies
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. Grading the same 6,030 answers with Claude Sonnet cost me $36 last month. 71% of these startups were never named once, even when the buyer asked ChatGPT for exactly what they build.

Typed LLM structured output, 0% malformed and ~0.4s
Ask an LLM for JSON and it types it out char-by-char while you parse and pray. Jev doesn't: hand it text + a schema, get a typed value in one pass — 0% malformed, ~0.4s, 1/76 the cost. No text, no rationale, bounded only. → https://t.co/2OUi9ofr1Z #LLM #StructuredOutput #AI https://t.co/K1kDt3rZLU

I’m surprised Jev for tabular data isn’t a bigger deal. Every ai spreadsheet company should be racing to rebuild their product ground up with Jev. When we were building people search last year we spent months optimizing the search algorithm. Here is Jev processing 100k rows for $2.50 in under 60s, no optimizations whatsoever.

Jev benchmark on counting letters in strawberry
can @typesafeai Jev count the r's in strawberry? no. 47% says 3, 47% says 2. a coin flip, same as every LLM. On 70% on 168 test words, it undercounts doubled letters like everyone then I gave it the letters instead of the word: ["s","t","r","a","w","b","e","r","r","y"] 168/168. same model, same question, 260ms @CompleteSkeptic is this expected?

Reader mode extraction with Jev
This one is a little more out there and not really ready yet, but because @rsg asked if it was possible, I had to try it. This attempts to use Jev to extract a "reader mode" for content. And it... sort of works? It butchers many examples, but so do many existing code-based attempts. This has given us ideas for more targeted applications of content extraction.

DeepScrape web extraction with one selector call, then deterministic pulls
LLM overhead kills agent loop economics. Routing decisions, relevance scoring, next-worker selection. Each call costs $0.03. In a tight loop that's your entire budget. I built DeepScrape with the same principle in mind. One LLM call to derive a CSS selector. Every subsequent extraction is deterministic. No more paying per-extraction for structured web data. Same logic Jev applies to routing decisi

Robotic grasp planner using DINO, SAM 3 and depth
Grounding DINO gives a box, SAM 3 gives a mask. The mask fused with RealSense depth tells us where solid material is and how wide, so the grasp goes to a line across the part with room for both fingers. For the chrome parts depth is useless (the camera sees the ceiling in it), so we fit the part's STL silhouette to the SAM 3 mask instead, table contact fixes the height. Then https://t.co/URMcA9opc

Entity and relationship extraction pipeline using Jev, 25x faster
First real use case with Jev got up and running last night. Used it with GLiNER 2.5 base to help dramatically speed up entity / relationship extraction. GLiNER by itself for Graph RAG over a huge document corpus is fairly unreliable. Using Jev to help determine what it got right and then send everything else to my local 35B model. ~25x performance boost.
