How I shrunk a Russian embedder to 24 million parameters — and almost ruined it with one digit

An engineer trained a lightweight Russian dense retriever, STRIZH, with 24.4M params and 4 layers, for local RAG on shared GPU. A single wrong number in tokenizer config (model_max_length=256) dropped Recall@10 from 0.589 to 0.448, nearly voiding the work. The model is meant for fast first-stage retrieval on AMD Strix Halo, competing with bge-m3 in co-residency scenarios.

Why Micro F1=0.94 May Hide a Useless Classifier: A Multi-Label Problem Breakdown

Using the example of AI moderation for Discord, the article shows that the aggregated micro F1 metric can mask failures on rare but critical classes. The author warns against blindly following the KISS principle in multi-label tasks and explains how class imbalance, loss function choice, and checkpoint selection metrics affect actual model quality.
