# Antonio V. Franco Antonio V. Franco is an AI engineer and independent researcher. This blog publishes first-hand technical work on LLMs, SLMs, open-source models, fine-tuning, distillation, agentic AI, pricing/cost analysis, and practical model stack decisions. Articles are written from real testing and real workloads, not from press releases. Canonical: https://antoniovfranco.com/ ## Scope - Agentic AI and Small Language Models (SLMs) - Open-source vs. closed model evaluation - Model pricing and cost-per-token analysis - LLM fine-tuning and distillation tooling - Practical AI stacks for independent researchers and startups ## Articles - Title: Quantizing an LLM Isn’t Enough: How to Prove That a 4-bit Model Still Deserves to Go Into Production URL: https://antoniovfranco.com/posts/2026/quantizing-an-llm-isnt-enough-how-to-prove-that-a-4-bit-model-still-deserves-to-go-into/ Date: 2026-08-29 Description: When I started designing how quantization should work in Huyawo, the first question was the most obvious one: how much could I reduce the size of a model wi.
