Open‑Weight LLMs Trail Closed Models by Just 4‑6 Months on Public Benchmarks
A new analysis of 17 benchmarks (9 public, 8 private) finds open‑weight models are only 4–6 months behind the leading closed‑weight models on public tests, versus an 8–10‑month lag on private ones. The gap narrowed to its minimum around DeepSeek R1’s launch in Jan 2025, then has slowly widened.
