Curious why OpenCode instead of a more 'full-fat' version of Pi with the larger model?
I feel like the amount of context bloat that OpenCode puts these small models into the dumb zone too quickly. The system prompt alone is 9k tokens, and when you add your own setup it can easily creep up to 15k.
I disabled many built in skills and increased the context size. I also use little-coder that is based in pi.
