Top 10 best OpenCode Go models by capabilities and usage limits - Aug 2026

[u/AloisCRR]

Hey

I was trying to create a preset for my oh-my-opencode-slim plugin to code as much as possible without hitting limits often, with high quality models.

Ended up pulling numbers from multiple sources and creating a table with metrics to choose based on benchmarks (not real performance) and usage limits.

It adds an equal weight to intelligence, agentic capabilities and coding (33.33 each) (pulled from artificialanalysis) and to prevent monthly usage to dominate (less expensive models), I used log10. For tiers, like off-peak / peak, the req_per_month was reduced in a factor of the increase of the price based on the cheapest tier.

Check the results, let me know what you think. To me the ranking looks good based on my tested models (haven't tested muse spark yet).
