Google's Gemini 4 series, including Argon and Carbon variants, anchors the lab's third-place position on arena.ai's Code Arena WebDev leaderboard through consistent scores in the 1670-1768 range on agentic front-end and full-stack tasks. Anthropic and OpenAI occupy the top two lab ranks with higher-scoring Claude Opus/Sonnet and GPT-6 models, leaving Google well ahead of the next cluster of labs such as Alibaba and Meta. Recent October updates, including OpenAI's GPT-6.1 Terra release and DeepSeek's open-model gains, have not displaced Google's standing as of late-month snapshots. Traders see limited room for change before the October 31 resolution, though a late surge from another lab's new model or a scoring shift on multi-step web workflows could still alter the final lab ranking.
