TLDR AI

OCR MODELS EXPLAINED

Recent advancements in OCR models, such as Chandra and Deepseek, eliminate traditional scripting by using vision transformers that convert raw pixels into semantic tokens. These models improve accuracy by understanding and compressing visual data into concise tokens before decoding them into text, allowing context-aware text recognition. Deepseek-ocr achieves this efficiently with ~10x compression, enabling flexible adaptation to different fonts and handwriting styles without retraining.

GHOSTS IN THE CODEX MACHINE

After weeks of user reports claiming Codex had gotten worse, echoing a perennial concern that frontier labs secretly downgrade their models, OpenAI assembled a squad to investigate every possible culprit and publish their findings. The team found no smoking gun, but instead uncovered a catalog of small bugs: older hardware subtly dragging down performance, a constrained sampling bug that made the model switch to Korean mid-sentence, and context compaction that quietly degraded accuracy in long conversations.

LARGE LANGUAGE MODELS GET ALL THE HYPE, BUT SMALL MODELS DO THE REAL WORK

Small language models are helping companies get real work done and reduce headcount. They are more affordable than large language models and, in some cases, better suited to the tasks at hand. The impact that AI is having on corporate productivity gains is the result of human engineers getting better at stitching together smaller, simpler AIs. Many companies have built internal knowledge factories that daisy chain together small AIs.
