This Week in the Arena: Four releases reshaped the Pareto frontier across Text, Code, and Agent Arena.
- After OpenAI’s DevDay, GPT-6.1 Sol (Max) entered Code Arena: WebDev at #3 and joined the Pareto frontier at $8/MToken.
- However, once Sonnet 5.5 entered the leaderboard later that day, Sol moved to #4 and fell off the Pareto frontier. Today, Sonnet is 2 points behind #2 GPT-6 Astra (Max) at 80% lower cost.
- Excitingly, Gemini 4 Argon (High) landed at #1 in Text Arena, #8 in Code Arena: WebDev (1679 pts), and #8 in Agent Arena (+7.92% net improvement).
- Finally, MiMo-V2.6-Pro and Flash entered Agent Arena at #5 and #9 among open-source models, respectively.
Agent scores for GPT-6.1 Sol and Sonnet 5.5 are coming soon. Stay tuned!
