Moonshot released the Kimi K3, a 2.8T-parameter MoE model with 104B active parameters/token, featuring innovations like Kimi Delta Attention (KDA), Gated MLA, and LatentMoE. The release includes infrastructure components such as MoonEP, FlashKDA, and AgentEnv, emphasizing system-level design. Despite open weights, running K3 requires significant hardware investment (minimum 8× MI355X GPUs, production at 64+ GPUs) with costs reaching six figures USD or tens of millions RMB. Hosted access is available via Perplexity, Baseten, and Together. Additionally, agent-based workflows are advancing with mobile orchestration, highlighted by ChatGPT Voice + Codex, Cursor's Start in India powered by Grok 4.5, and Perplexity's Personal Computer local agent with multi-model comparison via Model Council. "If you ever want to feel dumb just read the Kimi K3 technical report" captures community reaction to the dense technical details.
