Kimi K3 实现接近前沿的智能体性能,计划开源权重
月之暗面(Moonshot AI)的 Kimi K3 在 Artificial Analysis 智能指数上获得 57 分,与 Claude Opus 4.8 和 GPT-5.5 等顶级闭源模型相当。该模型在 GDPval v2 上取得 1668 的 Elo 评分,在 AutomationBench-AA 上获得 53% 的成绩并排名第一。月之暗面计划开源其 2.8 万亿参数权重,这将使其成为领先的开源权重模型。 Kimi K3 的表现证明开源权重模型在复杂智能体任务上可以与闭源系统竞争,有望加速开源 AI 的采用。计划中的权重开源将使前沿 AI 能力民主化,让研究人员和开发者能够基于接近最前沿的模型进行构建。它在真实工作流基准测试中的强劲表现,预示着其对企业自动化的实际价值。 Kimi K3 拥有 2.8 万亿参数、1M 上下文窗口,并支持原生多模态输入(文本和图像)。其 API 定价为每百万输入/输出 tokens 3/15 美元,缓存输入可享受 90% 折扣。该模型比前代 K2.6 少用了 21% 的输出 tokens,同时取得了更高分数,且每次任务成本(0.94 美元)与 GPT-5.6 Sol(1.04 美元)相当。权重尚未发布,但已计划开源。
@ArtificialAnlys@Kimi_Moonshot 转推1 张图片Kimi K3 scores 57 on the Artificial Analysis Intelligence Index. Its intelligence is comparable to Opus 4.8 and GPT-5.5 but remains behind Fable 5 and GPT-5.6 Sol. Moonshot AI has expressed plans to release the 2.8T parameter model's weights, which would make it the leading open weights model
Key results:
➤ Strong agentic task performance: @Kimi_Moonshot's Kimi K3 reaches an Elo rating of 1668 on GDPval v2. This is a marked improvement over K2.6’s 1190, surpassing GLM-5.2 (1514), GPT-5.5 (1494), and Claude Opus 4.8 (1600). However, it still lags behind Claude Fable 5 (1760). Kimi K3 also scores an impressive 53% and takes the #1 position on AutomationBench-AA, our implementation of Zapier’s Agentic SaaS workflow evaluation.
➤ Second-highest performance on AA-Briefcase (agentic knowledge work): On our private long-horizon knowledge work evaluation, Kimi K3 reaches an overall Elo of 1547, +732 points from Kimi K2.6 and behind only Claude Fable 5. It is well-rounded: its rubric scoring and analytical quality almost reach Claude Fable 5’s scores, while GPT-5.6 Sol continues to outperform other leading models on presentation quality.
➤ Set to lead open weights models once weights are released: Moonshot AI has not yet released the weights but expressed plans to do so. Once available, Kimi K3 would clearly lead other open weights models including GLM-5.2 (51) and DeepSeek v4 Pro (44). However, at 2.8T parameters, it is significantly larger than its open weights peers (eg. GLM-5.2 at 753B params and DeepSeek V4 Pro at 1.6T), as well as the Kimi K2 to K2.6 models (1T params).
➤ Cost per task ($0.94) is similar to GPT-5.6 Sol ($1.04), ~1/2 the price of Opus 4.8 ($1.80) and higher than open weights peers: Moonshot AI’s pricing for K3 is significantly higher than their K2 pricing (K3’s output token price is $15/1M tokens while K2.6 was $4). This positions the model as cheaper on a cost per task basis than Opus 4.8, similar to GPT-5.6 Sol ($1.04) and more expensive than open weights peers, GLM-5.2 ($0.32) and DeepSeek V4 Pro ($0.04)
➤ Improved token efficiency alongside higher intelligence: Kimi K3’s token usage on the Artificial Analysis Intelligence Index decreased significantly, using 21% fewer output tokens than K2.6. The new model used approximately 132M output tokens to complete all nine evaluations, compared to approximately 166M for K2.6, while achieving higher scores.
➤ Native multimodal capabilities: Kimi K3, like K2.6, is released with native image and text multimodal input. If weights are released, this will position Kimi K3 as one of the leading open weights models with multimodal input capabilities
Other model details:
Context window: 1M
Size: 2.8T total parameters
Pricing: The first-party API is priced at $3.00/$15.00 per 1M input/output tokens, with cached input discounted 90% to $0.30 per 1M tokens.
Modality: Native multimodal input supports text and images, and the model remains text-only for output.
Accessibility: Accessible at launch through Moonshot’s first party API. Model weights are not yet released but Moonshot AI has expressed plans to do so.
