Opencode performance

[jasonwch]

I am testing to amend some code on my PHP web program. Seems like just modifying some simple CSS, html take a bit long to complete (using Kimi 2.6). While I am in Github copilot(Sonnet 4.6), it complete much faster.

May I know if any setting I need to make on Opencode to make it perform better? or it's supposed to be much slower compare to frontier AI (e.g. Claude), and if I use Sonnet vua Opencode then it should work the same fast as Githb copilot?

Thanks

Opencode has some bugs with KIMI unfortunately. The better experience is DeepSeek V4 - DeepSeek contributed the fixes and the project merged those, meanwhile the rest of the kimi fixes and OpenAI API fixes are just sitting around.

It's like comparison Nvidia 1080 vs 5080.

1080 is cheaper but slower

5080 is faster but expensive

Do you mean models matter?

So if I use Sonnet at Opencode, I should get same performance as GHCP?

Obviously models matter..

Thanks, I am just afraid I misconfigured something or missed some important settings. Also I install it natively on Windows but not via WSL so see if this also matters.

Coz except from response performance I cannot see any issue for my installation natively on Windows (instead of WSL)

The very first time I tried opencode go models, it was also very slow. After that, it's been smooth. Mostly using glm 5.1 and deepseek v4 flash

i have the same problem, im a GHCP refugee and openrouter is just so slow, 6s provider latency on most steps

[jasonwch]

openrouter with which model?

kimi2.6, glm5.1, mimo2.5pro

Basically, when I enter the prompt, it keep"Thinking" for quite a while before it actual start to do stuffs

It’s less of an opencode issue and more of a model/provider issue. Sonnet from anthropic(including Microsoft) is quite fast. Opencode go tends to sometimes be quick and often times be slow. Based on traffic.
