The Gap Between Open and Closed AI Models Might Be Shrinking. Here’s Why That Matters

AI model capabilities are advancing rapidly, with open models about a year behind top closed models. Meta's Llama 3.1 405B took 16 months to match GPT-4's initial capabilities. The gap may shrink if Meta releases Llama 4 openly. The open vs. closed model distinction is complex, with debates on definitions and governance. Open models offer benefits like access and transparency, but risk misuse. Policymakers are struggling to regulate powerful AI systems that could reshape information environments and potentially cause harm.
