Build an answer corpus that preserves source-question provenance and blocks duplicate evidence across retrieval splits.

Frozen benchmark over nine yearly FAR revisions: dateless RAG answers from the wrong year 80% of the time; year-pinning fixes it but breaks change questions.

Build a Shorts retrieval corpus that separates channel biographies, preserves source links, and checks creator leakage.

A char-level transformer trained from scratch on an $8 ESP32-S3. Not inference: the chip runs the full training loop, with backprop written by hand in C. - Carloscodix/qapla

How LLM-authored templates and deterministic generators replace runtime guesswork in complicated...

Noah Lee had an outstanding weekend in Texas. From Corpus Christi to East Texas, he performed well in the bull riding.

Modern retrieval systems, whether lexical or semantic, expose a corpus through a fixed similarity interface that compresses access into a single top-k retrieval step before reasoning.…

Blockify claims 40x corpus reduction and 2.3x relevance gain over naive RAG. Open-source on GitHub, but lacks benchmark details.

Your corpus shifted, your fine-tune landed, recall dropped. Here is the 50-line per-class drift monitor that catches it before users do.

Oil exports are booming from the U.S. Gulf Coast thanks to the Middle East supply disruption caused by the Iran war.

Researchers say works may have been incorrectly inscribed in 1700s, leading to centuries-long misunderstanding

How does a language model learn it's name? Why does Claude turn poetic when you ask about...

Cross-encoder rerankers don't always help. Four cases where two-stage retrieval drops recall@5 below the bi-encoder, with code and a decision rule.

BEIR still shows BM25 holding its own on exact-match domains. Here is the decision rule, the Postgres setup, and when hybrid actually pays.

From Reddit - r/environment: Corpus Christi is on track to be the first American city to completely run out of water, as its reservoirs near empty following a five-year drought.

The five RAG failures that survive your eval suite and break in production. Each one with a small mitigation snippet you can paste in today.
