Kimi K3.1 Pro pricing notes
Not included in any plan: every request bills from credits.
Context caching is automatic: cache hits bill at $0.20 per 1M input tokens, a tenth of the input rate.
Thinking is always on, at max effort by default, and reasoning tokens bill at the output rate.
GPT-6.1 Sol pricing notes
Requests over 272K input tokens bill the entire request at 2x the input and cache rates and 1.5x the output rate; the listed price is the short-context rate.
Cache hits bill at $0.10 per 1M tokens, half GPT-6 Sol's $0.20; cache writes cost $2.50 (30-minute) or $5.00 (12-hour).
The first model of Moonshot AI's K3.1 series and its most capable Kimi to date: a 3T-class reasoning model with native vision and a 1M-token context. It costs a third less per token than Kimi K3; Moonshot says full weights ship by November 4, 2026.
Pick it if
you want Moonshot's current flagship at a lower rate than Kimi K3
your prompts outgrow the 256K context of Kimi 2.6 and 2.7 Code
you resend long prompts, so cache hits bill at a tenth of input
Skip it if
you need temperature or top_p control: they are fixed
Kimi 2.6 or 2.7 Code covers your workload at a lower rate
OpenAI's GPT-6.1 Sol, for complex coding and professional work, replaced GPT-6 Sol at the same $2 / $10 rate with half Sol's cache-hit price. It sits below GPT-6 Astra and above GPT-6 Luna in price.
Pick it if
you want complex coding work at one-fifth of GPT-6 Astra's token price
you resend long prompts; cache hits bill at 5% of input
your prompts mix text and images
Skip it if
GPT-6 Luna at $0.10 / $0.50 covers your workload
your prompts often pass 272K input tokens; the whole request then bills higher
FAQ
Which is cheaper, Kimi K3.1 Pro or GPT-6.1 Sol?
Kimi K3.1 Pro and GPT-6.1 Sol list the same input and output prices. On a coding-agent session (2M tokens in, 60,000 out) Kimi K3.1 Pro costs $4.60 and GPT-6.1 Sol $4.60.
Can I switch between Kimi K3.1 Pro and GPT-6.1 Sol mid-task?
Yes. In an Octomind session, /model octohub:kimi-k3.1-pro and /model octohub:gpt-6.1-sol switch models without losing the conversation, so you can draft on one and review on the other.
