  "text": "Have open source models closed the gap with proprietary ones? We've tracked three years of Arena data across three arenas. The short answer: mostly yes.\n\nIn Text Arena, the proprietary winner had a +250 Arena lead. By early 2025, it had fallen to low double digits, and at its narrowest was almost closed entirely.\n\nToday, the proprietary lead is about +30 points. It separates #1 from roughly #18 on the current leaderboard.\n\n- Open source has quickly closed most of the gap\n- The biggest gains happened before 2025\n- The remaining gap is small in points, but still large in rank\n\nGet a deeper look into the race for Code Arena: Frontend and Expert prompts in the thread 🧵",
