Fine-tuning 70B parameter models used to require a $200k cluster and 3 weeks of trial and error. With 4x NVIDIA A100 80GB GPUs, LoRA, and the right pipeline, you can get a production-ready CodeLlama 70B variant tuned on your proprietary codebase in under 48 hours for less than $1,200 in cloud spend. This tutorial walks through every line of code, every config tweak, and every benchmark we used to ship a code completion model that outperforms the base CodeLlama 70B by 22% on internal Python tasks. 📡 Hacker News Top Stories Right Now LLMs consistently pick resumes they generate over ones by humans or other models (263 points) Meta's Pyrefly sabotages competing Python extensions without telling you (27 points) Barman – Backup and Recovery Manager for PostgreSQL (72 points) How fast is a macOS VM, and how small could it be?
