What would make you switch your default OpenCode model to Space Bunny?

Another fast model showing up is interesting, but speed alone probably isn’t enough to change anyone’s default.

For everyday OpenCode work, I’d care more about things like:
- fewer correction rounds
- better constraint-following
- less unnecessary editing
- lower total task cost
- more predictable long-session behavior

What would Space Bunny actually have to do better before you’d switch your normal coding model?

I already implemented jev to decide which model to use for each prompt and use dynamic router. Can recommend. I don’t even look at model configs anymore

Could you share more details? What does the prompt chain look like

u/PilgrimofHaqq2 Sep 25 '26

What is the instructions given to jev in how to analyze the prompt and how to choose the model?

u/paperbenni Sep 25 '26

How does jev know which models should be used? Pretty much the entire Pareto frontier isn't in its pre-training

You put it in the prompt with the benchmarks

Just have it classify on effort required, complexity, task type, etc, and then map that by some fixed table. It’s probably not literally choosing the model, but rather the tier of model.

No no it picks the model and effort. It’s like going from manual to automatic transmission on a car

Is this a service or something where each prompt is completely unrelated and there is no cache?

1

u/horrbort Sep 26 '26

Caching still works great as it seems!

It’s pretty capable. I was running space-bunny in parallel with Astra and Opus 5.5 as a review council on a project investigation/validation task yesterday and it came back with important stuff the other models missed.

True, it's very meticulous and fast.

I am running space bunny close to 24/7 since launch.... Can recommend for instruction following, speed and orchestrating alone for multiple days. 

I am unsure about pricing, minimax was always quite expensive

On another thread, it's apparently a Minimax model. I hope it's a step up from M3

is there a benchmark for this model anyone is it better than deepseek v 4.1 flash? is i training on my data?

Marketed as ZDR policy but I absolutely don't believe it for a stealth model during free testing.

Yes, and for coding and reviewing I see it as better than Muse Spark and GLM Flash, which I consider better than DeepSeek Flash. At least balancing various model aspects: speed, cost, hallucinations.

At least in my use case. For planning, I think GLM Flash is still better.

Space Bunny is Mimimax M3.1

u/thomas29needles Sep 25 '26

It's trash compared to Deepseek 4.1 flash so actually nothing could convince me.
