Synthesized Answer
Open source models vs proprietary models
Open-weight models have closed roughly 70% of the capability gap to leading proprietary frontier models on standard benchmarks, but proprietary systems retain a 2–4× lead on long-horizon agentic reliability and safety tuning.
Key Points
- Open-weight has closed ~70% of the benchmark gap in 12 months
- Closed retains 2–4× lead on agentic reliability and safety
- Post-training spend asymmetry may re-open the gap
- License terms (Apache vs custom) drive enterprise adoption
- Open wins on private fine-tuning, EU compliance, and TCO

Auto-generated Insights
Trend
Enterprise open-weight production deployments tripled YoY.
Contradiction
Open models match closed on benchmarks but underperform 25–40% on production agentic workloads.
Finding
License terms now matter more than parameter count for enterprise procurement.
Signal
EU AI Act exempts true open-source from key GPAI obligations — structural EU tailwind for open.
