Summary

A comprehensive benchmark of 18 LLMs on OCR tasks (7k+ calls) reveals that cheaper and older models often match premium accuracy at a fraction of the cost, with full dataset and framework open-sourced.

**TLDR;** We were overpaying for OCR, so we compared flagship models with cheaper and older models. New mini-bench + leaderboard. Free tool to test your own documents. Open Source. We’ve been looking at OCR / document extraction workflows and kept seeing the same pattern: Too many teams are either stuck in legacy OCR pipelines, or are overpaying badly for LLM calls by defaulting to the newest/ biggest model. We put together a curated set of 42 standard documents and ran every model 10 times under identical conditions; 7,560 total calls. Main takeaway: for standard OCR, smaller and older models match premium accuracy at a fraction of the cost. We track pass\^n (reliability at scale), cost-per-success, latency, and critical field accuracy. Everything is open source: [https://github.com/ArbitrHq/ocr-mini-bench](https://github.com/ArbitrHq/ocr-mini-bench) Leaderboard: [https://arbitrhq.ai/leaderboards/](https://arbitrhq.ai/leaderboards/) Curious whether this matches what others here are seeing.

Benchmarking LLM Judges for Mobile Agent Evaluation

arXiv cs.AI

This paper introduces MobileJudgeBench, a benchmark with 931 human-annotated trajectories for systematically evaluating LLM-based judges on mobile agent tasks. It finds that simple baseline judges with sampled screenshots rival purpose-built methods, with the LLM backbone being the primary driver of quality.
