Comparison
Nexum Router vs the opencode Go plan
opencode is a great CLI — and Nexum Router works inside it. This page compares the opencode Go subscription with Nexum Router as the model plan behind your opencode sessions.
Last updated: 2026-08-21
The short version
The opencode Go plan costs $10/month and enforces three concurrent usage caps: $12 of usage per 5 hours, $30 per week, and $60 per month. Nexum Router costs $5.50/week with no hourly, weekly, or monthly usage caps — and you can keep using the opencode CLI by pointing it at the router's OpenAI-compatible endpoint.
- Nexum Router: $5.50/week, no usage windows or dollar caps
- opencode Go: $10/month with $12/5h, $30/week, $60/month caps
- Both work inside the opencode CLI — the router is just the model plan
- Nexum includes Qwen 3.7 Max, Xiaomi Mimo 2.5, and Meta Muse Spark 1.2
Use Nexum Router inside opencode
Point opencode's OpenAI-compatible provider at
/router/v1 with your Nexum key and pick a model ID (qwen-3.7-max, xiaomi-mimo-2.5, meta-muse-spark-1.2, or meta-muse-spark-1.3). Setup takes about two minutes.- Same CLI, same workflow — different usage ceiling
- No fallback to weaker free models when a cap hits, because there is no cap
- Cancel anytime; billing is weekly
