How this price is scoped: USD is FX-derived from StreamLake's RMB list price (¥1 in / ¥0.2 cached / ¥4 out per 1M) at 6.7476 CNY/USD (2026-08-07); re-checked on FX drift, not a promo.
Price receipt
We read Kwaipilot's own pricing page on and found KAT-Coder-Air-V2.5 listed with a price on the same row — that read is where the number above comes from. The page prices it in CNY; the USD above is converted from that list at a dated FX rate — see the price note for the figures. We keep the page text we read; its content hash is 6bd7234dff.
Overview
Kwaipilot KAT-Coder-Air V2.5 — an agentic coding model from Kwaipilot, Kuaishou's coding-model team, sold first-party through StreamLake (Kuaishou's enterprise cloud) on its Wanqing (万擎) model platform, whose pricing table lists it in RMB (¥1 in / ¥0.2 cached / ¥4 out per 1M tokens, unit stated as 元/百万 tokens); the USD shown is converted from that RMB list at a dated exchange rate (6.7476 CNY/USD, 2026-08-07). StreamLake's standalone KAT-Coder product page, which scored it 42.4% on SWE-bench-Pro, was taken offline by the vendor on 2026-09-18 and now returns 404, so the Wanqing platform page is the surface this row cites. Context window 256,000 with 80,000 max output. The Apache-2.0 KAT-Coder-V2.5-Dev weights on HuggingFace are a separate research variant, not this hosted SKU. Release date is first public catalog availability (OpenRouter, 2026-07-10), not a first-party announcement.
