KIMI K3.1 PRO API PRICING
What Moonshot AI charges for Kimi K3.1 Pro, in USD, cross-checked daily against the public pricing dataset. Effective price — if there's a promo running, this is the promo.
NOTE: Moonshot's current flagship, released in October 2026, with a 1M-token context. Cache writes are billed by lifetime, like Claude's, but cheaper: a 5-minute write costs 1x input ($2.00) where Anthropic charges 1.25x, and a 1-hour write 2x ($4.00). Cached reads: $0.20.
WHAT THINGS ACTUALLY COST ON KIMI K3.1 PRO
| Scenario | Tokens in / out | 1 run | 1,000 runs |
|---|---|---|---|
| A typical prompt (300 tokens in) | 300 / ~900 | $0.0096 | $9.60 |
| A 20-turn conversation (context re-sent) | 4,000 / ~4,000 | $0.05 | $48.00 |
| Summarizing a 10-page document | 8,000 / ~3,200 | $0.05 | $48.00 |
| One agent run (tools, retries, thinking) | 2,000 / ~12,000 | $0.12 | $124.00 |
| A code review request | 1,500 / ~3,750 | $0.04 | $40.50 |
Output sizes assume the same editorial ratios as the Burn Calculator (3x for prompts, 6x for agent runs). Estimates, not invoices.
VS. THE REST OF THE BOARD
“Same job” = a 1,000-token prompt with a 3,000-token reply, priced on both models. Cheaper is not always better. It is, however, always cheaper.
PRICE HISTORY
Kimi K3.1 Pro joins the board at $2.00 in / $10.00 out per MTok, with Claude-style cache writes by lifetime: 5 minutes at 1x input, 1 hour at 2x. Anthropic charges 1.25x for the 5-minute one.
