I think they envision Pro plan as "just a taste of AI, enough to lure folks into the Ultra plan" but that won't work for me when Codex is half the price and DeepSeek 4 Flash is 1/10 of their price per task.
So I'll downgrade just enough to keep my Google Drive space. And use DeepSeek 4 as workhorse plus Codex or Copilot for advanced stuff.

It adds a button to VSCode to open a tab with opencode loaded. It's a bit better than just opening the CLI because it has some vscode integration.
With their $10/mo opencode go plan: https://opencode.ai/go
For my use it's about endless use of DS4 Flash on high setting. I find high better than max because it's less chatty.
The best thing is the speed. So many tokens per second.

I haven't tested openrouter but I expect it to be slightly less cheap because it charges per token and opencode Go plan is a $10/mo fixed price model. Economies of scale leads me to think that for heavy use, openrouter will be more costly since opencode Go can subside heavy users like me with money from light users (just like gyms do with people that pay but barely use it).
With that said, I find vscode native copilot chat more pleasant to use, but also more laggy for large sessions.
opencode configuration is less polished and you'll have to grok around for some things. For example opencode CTRL+p conflicts with VSCode CTRL+p. I changed opencode to use Ctrl+L instead.
