These models posted competitive intelligence index scores and strong arena results in mid-to-late October, positioning Meta ahead of most rivals on the filtered labs view while Google and Anthropic occupy the top two spots. Trader consensus reflects sustained momentum from open-weight availability and demonstrated agentic capabilities that boosted usage metrics. A late surge by OpenAI, Anthropic, or a Chinese lab on the final leaderboard snapshot remains the main scenario that could alter the outcome before resolution.
