Deep Dive: Teaching Arcee Trinity Mini to Read Medical Research with RLVR and GRPO

Bojan Jakimovski, an ML engineer, took Arcee AI's open-source Trinity Mini model and turned it into a biomedical specialist — extracting drug-protein relationships from scientific papers. No massive team. No million-dollar budget. Just open weights, a clever training technique called RLVR, and a weekend of GPU time. ⭐️⭐️⭐️ More content on Substack at https://www.airealist.ai ⭐️⭐️⭐️ In this video, I break down exactly how it works: the Mixture of Experts architecture behind Trinity Mini, why Reinforcement Learning with Verifiable Rewards (RLVR) beats traditional fine-tuning for domain special…
