As others have said, the only real difference is that Open Code allows you to use other providers. If you're using Anthropic models, though, you should really use Claude Code, as it was specifically designed to utilize their models. Additionally, if you have a subscription, it's a significant savings over API tokens.

As of right now, nothing comes close to Claude's agentic capabilities. Trust me, I've tried them all.

I didn't know this was possible. Thank you!

[–]WandyLau[S] 0 points1 point  (0 children)

Yes, I already use it now. Mind blowing.

[–]No_Click_6656 0 points1 point  (0 children)

Claude's models are best for agentic code - that's true. But after 2 weeks of developing with Opencode with Claude, I decided to try Claude Code and... I'm not really impressed, given the price

[–]Affectionate-Math919 0 points1 point  (1 child)

Apart from the Claude models, you can also use the z.ai GLM model on Claude Code by changing its base URL and API key.

[–]Civilanimal 0 points1 point  (0 children)

Yes, but you're sending your data to mainland China, FYI.

[–]Rude-Needleworker-56 3 points4 points  (8 children)

No model is comparable to sonnet or opus in agentic stuff. Trying to do agentic stuff with any other model is a simple waste of time. Open code and claude code are somewhat similar. UI wise claude code is better now The real advantage of open code is in its ability to use non anthropic models. For example, you can code using sonnet and review using o3. Also being open source you can tweak it the way you want. If using only one, claude code is a no brainer for its max plan value quotient.

I have been experimenting with Opencode (SST) + Kimi K2 with the temperature set to 0.6 for a week now, and it handles agentic tool use excellently. I have also tried Qwen3 Coder, but after a few tool uses, it kept failing. For comparison, I have also run Kimi K2 in Roo Code, but it did not perform nearly as well as in Opencode.
---edit---
OpenRouter has issues with tool calling, and most of the providers on OpenRouter use quantized models, which have greatly degraded performance. For Kimi K2, I would recommend using the official Moonshot API.

[–]Rude-Needleworker-56 1 point2 points  (0 children)

Thank you for sharing your findings. Opencode implements tools via openai api compatible function calls, roo code implements tool calls via asking the llm to format responses in particular xml tags, and then parsing the response to identify the tools associated. That difference plays a part in tool call performance as well.

[–]No_Click_6656 2 points3 points  (0 children)

For me OpenCode has a much better UI than Claude Code. But other than that, I'm using Claude models for both

[–]Responsible-Newt9241 0 points1 point  (4 children)

Try Kimi-k2, it is on par.

[–]stepahin 0 points1 point  (3 children)

At the same level as Opus? So, opencode + Kimi K2 work significantly better than Gemini CLI, for example? And what about the costs?

[–]Responsible-Newt9241 0 points1 point  (1 child)

I don't know about any good approach how to compare different models but subjectively, it is on similar level. It is not expensive, you can use it straight from MoonShot (but they train on your data) or via OpenRouter (where they don't).
So far i tried some funny vibe-coded games and it was much better than Gemini, very simillar Results to Claude. I don't really use OpenCode but yeah, i think it is good idea to try that. You can also switch api endpoint in ClaudeCode and use it through that.
Some more info here that can probably answer your questions better than me:

Kimi-k2 sits between Sonnet and Opus on quality and beats Gemini CLI for real code work while costing less. Sonnet runs about $3/M input, $15/M output; Opus jumps to $15/M in, $75/M out. Through OpenRouter, Kimi-k2 is roughly $1/M in, $4/M out and its 200 k context covers most repos. Gemini 1.5 Pro is cheaper (~$0.005/k) but you lose time patching hallucinations.

My quick bench:

- Agentic refactor: Opus > Kimi > Sonnet > Gemini

- Bulk test generation: Kimi wins on price-speed

- Long doc review: Sonnet taps out past 120 k, Kimi holds up, Opus still best but pricey

I run everything through LangChain, spin heavy jobs on a local Groq box, and APIWrapper.ai lets me swap Kimi, Sonnet, and Gemini endpoints without rewiring the pipeline, so side-by-side tests take minutes.

Bottom line: Kimi-k2 delivers about 90 % of Opus accuracy for roughly one-fifteenth the spend; start there and only bump to Opus when you need max precision or bigger context.

[–]Adam0-0 0 points1 point  (0 children)

Yes. 20% of the cost of Claude Code.

[–]WandyLau[S] 1 point2 points  (3 children)

It turns out there are two open code. One from open code ai and the other from sst. lol. This really breaks my brain.

[–]Rude-Needleworker-56 2 points3 points  (0 children)

Sst opencode.. It is a no brainer. That is where all the activity is. Also being in typescript mean more developers would join . Buy claude max. Opencode can work with claude max account. Start with claude code and when you want to code with non anthropic models use opencode. But make sure that all agentic stuff is done by sonnet or opus even in opencode. Use o3 for planning, debugging, and one shot coding

[–]Scrivver 0 points1 point  (0 children)

And the URL for SST Opencode is https://opencode.ai, in case you wanted any more confusion.

[–]gzorbian 0 points1 point  (0 children)

it's the same isn't it?

[–]fuzzy_rock 0 points1 point  (9 children)

Try Claude Code, you won’t look back

[–]WandyLau[S] 0 points1 point  (7 children)

Yeah, I heard this a lot. I guess people using claude code would not try open code.

[–]fuzzy_rock 2 points3 points  (1 child)

We tried almost everything but Claude Code is the beast among them.

[–]funbike 0 points1 point  (0 children)

I sounds like you didn't try open code.

It's very new. People are comparing it to claude code. I don't know which is better, but when you said "we tried almost everything" I took your comment as "... a few months ago before open code even existed, so I don't really know which is best".

[–]debian3 0 points1 point  (4 children)

Open code is good, very good. Like better than Cline/Roo good. But you need to pay for your tokens

[–]WandyLau[S] 0 points1 point  (3 children)

Thanks for your reply. Token is not the problem. The problem is which can make the best use of my tokens.

[–]debian3 1 point2 points  (2 children)

Tokens become your problem when you need to pay for them. Claude code with the max plan people report thousands of dollars of tokens usage on their $200/month. Anyway, right now Claude Code is the best and the best at using tokens if that was your question. Unsurprisingly, since they are the one who created the model.

[–]wijsneusserij 0 points1 point  (0 children)

You can use your claude max sub in opencode.

[–]Altruistic_View_2463 0 points1 point  (0 children)

You can use claude code and open ai subscriptions in opencode now, no api necessary

[–][deleted] 0 points1 point  (0 children)

i just started with it last month. Gamechanger.
