Kimi K2.5: moonshot API pricing is $0.60 per million uncached input tokens and $3.00 per million output tokens

The OnAirToday AI Progress Tracker recorded a verified change to Moonshot's Kimi K2.5 (version kimi-k2.5): Moonshot API pricing is $0.60 per million uncached input tokens and $3.00 per million output tokens.

Kimi K2.5 is Moonshot AI’s open-weight multimodal model for reasoning, coding, visual understanding and tool-using agents. Its published evaluations show improved coding and agent performance over Kimi K2 Thinking, but do not establish reliable autonomous operation without oversight.

What changed in this review:

• Context length is expressed as the vendor-documented 256K tokens.
• Vendor-published SWE-bench Verified performance is 76.8%; Terminal-Bench 2.0 performance is 50.8%.
• Added published reasoning, mathematics, coding and Humanity's Last Exam results with evaluation variants identified.
• SimpleQA Verified and Arena ratings are omitted because their current published values are not established.
• Added a reported Kimi K3-assisted Redis exploit case, explicitly distinguished from Kimi K2.5.
• Capability score 54 → 70

Teams building on Kimi K2.5 should confirm limits, pricing and benchmark coverage against the vendor's own documentation before relying on these figures.
