I'm working on a custom launcher for hooking up Claude Code with various providers (groups env variables in profiles) cause DeepSeek doesn't have vision and sometimes I need browser use with screenshots or Opus reasoning, for other tasks it's fine: https://ccode.kronis.dev/

  ccode --deepseek
(or whatever profiles are configured; tool is still in development, source available)

Also turns out that with a local proxy you can get Remote Control working and see the DeepSeek sessions in the desktop app, screenshots on the page. Other than that, I'm happy that it works pretty well and the discount is enough to make me consider going from Anthropic's Max subscription to Pro and using it only where DeepSeek is insufficient.

Overall though I'm not sure exactly how well Claude Code would stack up against OpenCode, since the latter overall feels a bit less hacky with 3rd party models and is even getting niche but nice features like a locally runnable web version: https://opencode.ai/docs/web/

I am curious - Is there a way to switch between models depending on the task? Because I believe Deepseek V4 is not multimodal and it will be good to switch back to Claude if vision or other capabilities are required.
reply
That's interesting. I thought Claude Code is not as good, therefore people want to use Claude model with other alternatives. This is the other way around.

Which begs the question, regardless of the model, which Claude Code alternative is better? (I keep saying "Claude Code alternative" because I don't know the term... LLM CLI?)

AFAIK the two most popular open source harnesses right now are OpenCode and Pi. They take a pretty different approach, OpenCode includes a lot of features while Pi is very minimal by design and focused on extensibility, to the point where many people are just asking Pi to write a plugin for itself whenever they want it to have a new feature. I personally like Pi's philosophy more and I think its developer justified the choices really well in his blog post:

The common term for a tool that wraps an LLM with a workflow is “harness”.

Surprised Anthropic hasn't done anything to restrict Claude Code from using other providers.
reply
The value of Claude Code the harness isn't that great. There's a lot of other good harnesses out there.
reply
What’s your favourite harness? Is there any benchmarks for harness like LLMs have for swe verified?
reply
I thought so, and then I tried Opencode and Codex and started to appreciate Claude Code a lot more. They've actually done great work the small details.
reply
Good or better? Curious which would be in either bucket.
reply
Probably a matter of taste. I prefer the harness I wrote, I don't want to go near Anthropic's bloated mess of a harness with a 10-meter pole.
reply
And it gets dragged down by Anthropic actively injecting unhelpful things into prompts without telling users about them (https://github.com/anthropics/claude-code/issues/58262).
reply
At this point in the AI wars, it is probably better to have more users of Claude code rather than restrict which LLMs it can connect to. Claude code is probably (currently at least) stickier than the LLM model itself. Getting people into the Claude code ecosystem is worth it.

Later, they can always lock it down more or add Claude LLM only features to it.
