After a year of development, I released X-AnyLabeling 3.0 – a multimodal annotation platform built around modern CV workflows

"Hi everyone, I’ve been working in computer vision for several years, and over the past year I built X-AnyLabeling. At first glance it looks like a labeling tool, but in practice it has evolved into something closer to a multimodal annotation ecosystem that connects labeling, AI inference, and ..."

Identity collapse in LLMs is an architectural problem, not a scaling one

"I’ve been working with multiple LLMs in long, sustained interactions, hundreds of turns, frequent domain switching (math, philosophy, casual context), and even switching base models mid-stream. A consistent failure mode shows up regardless of model size or training quality: identity and coherence ..."

🎯 LLM Criticism β€’ Cognitive Ontology β€’ Symbiotic Coupling
πŸ’¬ "Companies can't offer coherent models that don't fall behind or become unrealistic." β€’ "Coherence is not decreed by a central module, but emerges from the regulated interaction of all Custodians under the reference of the final value (V_f)."

I was terrified to let Llama 3 query my DB, so I built a WASM-powered "Airgap" Middleware. Here's the code.

"I wanted to let Llama 3 answer questions from my real Postgres DB. I couldn’t bring myself to give it a direct connection. Even read-only felt unsafe with PII and margins in the schema. Most β€œAI SQL guardrails” rely on regex or JS SQL parsers. That felt flimsy β€” especially with n..."

Replace, Don't Expand: Mitigating Context Dilution in Multi-Hop RAG via Fixed-Budget Evidence Assembly

"Retrieval-Augmented Generation (RAG) systems often fail on multi-hop queries when the initial retrieval misses a bridge fact. Prior corrective approaches, such as Self-RAG, CRAG, and Adaptive-$k$, typically address this by \textit{adding} more context or pruning existing lists. However, simply expan..."
