OpenCode launched a couple of months ago so that makes sense that it's worse. It's much better than Claude Code now. Somehow for the same model, opencode completes the same work faster than claude code and the ux is much better.
Here adoption is a combination on the tool and the model.
If people can’t pay the model to use the tool, they might not use the tool even if it’s better.
That’s what anthropic is doing.
It might be faster, but it’s more expensive.
The only way remains to try and lock consumers into your ecosystem.
