OpenCode Go is an optional provider for OpenCode and similar coding-agent clients, with Go priced at $10 per month and Go Plus at $40 per month.
For Kimi K3.1 Pro, the listed token prices are $2 per million input tokens, $10 per million output tokens, $0.20 per million cached-read tokens, and $2 per million cached-write tokens. The monthly usage allowance for that model is listed as $15 on Go and $60 on Go Plus. The documentation says five-hour and weekly allowances are 20% and 50% of the respective monthly limit.
Subscribers obtain an API key, connect the provider, and select a model. Go subscriptions are limited to single-member workspaces; those workspaces cannot invite members. OpenCode lists Claude Code, Codex, Hermes, Pi, and Raycast among validated clients.
The page says the model list may change. It does not establish when Kimi K3.1 Pro was added, its performance relative to other Kimi models, or whether availability is identical across all regions and clients.
