Coding harnesses make a big difference, and OpenCode is notably less effective than Claude Code (1) in my experience, (2) with the models I've tried it on. (I've not yet tried it with DSv4.)

If using something open source, I'd say Forge Code has better results than Open Code, at least according to Terminal Bench.

As someone who does use other models with CC, I am curious about opencode, what extra features does it have that you find essential?

I like being able to add a wide array of models, define perms for agents and subagents, turn MCPs on and off at will, and be able to fix bugs I find in it.

fair enough...any drawbacks that you've found?

Its UI isn't as slick, and it has bugs, but so does CC and you can submit a PR to have them fixed in OC.

More features than CC ?

Also opencode tracks you by default. Its not safe. Every first prompt you send is routed through their servers, logged and they can use your data however they want

I could not find any evidence of prompt logging. The code is open; can you point me to it?

When you send your first message and opencode generates a title automatically, it uses the free opencode/gpt-5-nano model from the OpenCode Zen provider at https://opencode.ai/zen/v1

Ask AI to look at the code for you

We don't have any proof they're not logging everything, by default we should assume they are

I did read the code. OpenCode uses your global `small_model` (https://github.com/anomalyco/opencode/blob/dev/packages/open...) or title agent (https://github.com/anomalyco/opencode/blob/51e310c9/packages...)

OpenCode Zen is their own service provider; they see your prompt the same way OpenAI and Anthropic do. Somebody has to see your code, unless you host your models yourself.

So, by default, they read our prompts. What else is hiding ?

I thought this was debunked awhile ago. ?
