Frontier coding capability has plateaued since Opus 4.8 as OSS models close in at 10-50x lower cost

AI researcher Yuchen Jin identifies two trends shaping the coding-model landscape:
- Frontier LLM coding capability has plateaued — no major jump since Opus 4.8.
- Open-source models keep closing the gap with closed frontier models while costing 10x-50x less.
He argues this explains the massive enterprise shift from closed to open-source models.
