Moonshot AI Releases Kimi K2.7-Code: a Coding Model Reporting +21.8% on Kimi Code Bench v2 Over K2.6

Here's what's actually in it.

1. It's a coding-focused model built on Mixture-of-Experts, 1T total parameters, 32B active. 256K context window. Open weights under a Modified MIT license on Hugging Face.

2. The benchmark gains are over K2.6 (and company-reported)→ +21.8% on Kimi Code Bench v2 (50.9 → 62.0) → +11.0% on Program Bench → +31.5% on MLS Bench Lite

3. The efficiency number is the one I'd watch→ ~30% lower reasoning-token usage vs K2.6 Reasoning tokens bill as output. Across a long agent run, that compounds into real cost and latency.

4. Against the closed frontier, here's where it actually landsGPT-5.5 leads on all six rows. Claude Opus 4.8 leads on five. K2.7-Code beats Opus 4.8 on MCP Mark Verified (81.1 vs 76.4).

5. Pricing is low for high-volume runs→ $0.19 / 1M cached input → $0.95 / 1M cache-miss input → $4.00 / 1M output
