Coding access now splits into two mainstream routes: subscription plans that trade a monthly fee for quota — Moonshot AI's Kimi Code is the representative — and metered APIs where you pay per token, DeepSeek being the classic example. Both routes changed this October: Kimi K3.1 Pro shipped, and DeepSeek's peak/off-peak pricing plus caching matured. Time to redo the math. This extends our model selection by scenario series.
Kimi Code: What the Subscription Buys
Kimi Code currently offers six model IDs: k3.1-pro and k3.1-pro-highspeed (3T-class, 1M-token context, thinking-only), k3 and k3-256k (the 2.8T previous flagship), kimi-for-coding (K2.8 Preview, officially positioned as near-K3 with more efficient thinking, aimed at completion and routine development) and its Highspeed sibling (K2.7 Code Highspeed, roughly 5-6x output speed at about 3x quota). Tiers: the K3.1 Pro series requires Plus and above, with 1M context reserved for the Pro tier; the Highspeed variant runs 2-3x faster at about 2x quota — effectively trading quota for wait time. Usage constraints are covered in our K3.1 Pro hands-on: thinking-only, new sessions recommended, native APIs for third-party tools.
The DeepSeek API: Doing the Metered Math
Metered pricing shines when load swings: deepseek-flash costs $0.15/$0.30 per million input tokens (off-peak/peak) on cache miss, $0.60/$1.20 for output, with cache hits from $0.003. Peak hours are only UTC 01:00-04:00 and 06:00-10:00 Monday to Friday; weekends are entirely half-price. A 2,500-request concurrency cap comfortably pipelines automation. The integration surface is wide too: beyond the OpenAI-compatible endpoint there's an Anthropic-compatible one, and we counted nine coding agents already working with the DeepSeek API (Harness, Claude Code, Codex and more) — parameters in our quick reference.
Match the Route to the Workload
For fixed monthly budgets, heavy conversational coding, and individuals or small teams who want a 3T-class flagship with 1M context, Kimi Code's subscription is the lower-friction choice, and Highspeed eases the wait on a thinking-only model — at the cost of quota accounting, since Highspeed and long contexts both burn quota at multiples, and heavy months require watching usage. For CI pipelines, batch code review and overnight jobs, a metered API with off-peak scheduling stays controllable: you pay only for actual usage as load swings, and cache hits push multi-round input costs toward zero. For coding tasks that need image input — screenshot-to-UI, design-to-code — deepseek-flash currently supports vision while K3.1 Pro does not. The routes aren't exclusive: subscription for daily interaction plus metered for automation is already a common hybrid.
