SpaceXAI 发布 Grok 4.5，在 Artificial Analysis 的 real‑world agentic 知识工作基准 GDPval‑AA v2 上获 Elo 1543，排名第 4，仅次于 Anthropic 最新 Claude 模型。每个 GDPval 任务成本仅 $0.49，低于 GLM‑5.2 和 Kimi K2.6，比排行榜前列模型便宜近 90%，处于性能‑成本帕累托前沿。完整评估结果即将公布。
SpaceXAI just released Grok 4.5, and it ranks #4 on GDPval-AA v2 with an Elo of 1543 - behind only the latest Claude releases from Anthropic on real-world agentic knowledge work tasks
Grok 4.5 achieved this score at a cost of $0.49 per GDPval task to sit clearly on the Pareto frontier for performance versus cost. This cost is lower than GLM-5.2 and Kimi K2.6, and nearly 90% cheaper than the models ahead of it on our leaderboard.
We’re finalizing the remaining Artificial Analysis Intelligence Index evaluations and will share final results soon.
Thanks to @SpaceXAI and @elonmusk for their collaboration testing this model ahead of release, and congratulations on the launch!
