Kimi突发K2.8：性能逼近K3，百万上下文全员开放

TL;DR - Moonshot AI launched Kimi K2.8 Preview across Kimi Code and Kimi Work, positioning it as a lower-cost model with performance reportedly near flagship K3. The release broadens access to 1M-token context and strengthens Kimi’s offering for routine coding and agent workflows, though no benchmark results were disclosed.

• K2.8 supports low/high/max reasoning-effort settings, plus image and video inputs.
• Coding and agent capabilities are described as improved over K2.7 Code, with better reasoning efficiency.
• All Kimi Code membership tiers, including free, receive the 1M-token context window; K3 requires higher paid tiers for equivalent context.
• Existing kimi-for-coding traffic is upgraded transparently to K2.8 Preview with the same model ID, while some non-thinking K3 requests are redirected to it.
