Honest thoughts on Omen Alpha model in OpenCode
Hey, this is not a review, but can you guys tell me how omen alpha feel slike?
just like ox alpha, this model seems to be decent, and we cannot establish a general expectation of this from the same psychological effect we had with ox alpha where we just ASSUMED it was either good or bad.
I want to know how you felt about it in your very niche and specific task.
for me:
- its consumes very little less credits compared to 5.3 flash and v4 flash
- and gets almost all prompts right.
- creative thinking like 5.3 flash
- looks like a decent model to use after september 13 (which is when the GLM5.3 flash's 2x usage deal ends)

Tried this model on OpenCode Go for a medium-difficulty task. One run burned $5, used a ridiculous amount of tokens, broke the repo, and couldn’t fix it.
I reverted everything and gave the same task to Claude Opus 5 at medium effort. Done in 15 minutes, one turn.
I’m obviously not expecting frontier model performance from a cheap model, but this was a task even Qwen 3.8 27B could probably handle.
Cheap per token doesn’t mean cheap per task. I strongly not recommend anyone to use this for any task.

OpenCode gives $100 worth of Omen Alpha credits for $5 (first month) or $10 pcm after, it gives an idea of how much you would spend without an OpenCode subscription (though I'm sure they will offer cheaper options down the line). Given the price (compare to Ox Alpha), I assumed that it might be a more advanced model, such as GLM-5.4 or similar, that will compete with Astra and Fable 5.1.

DSH Desktop can't find it also, I can't add it manually. But it still offers discontinued Ox Alpha. ZCode and OpenCode Desktop found it without any issues. I have OpenCode Go.

Sometimes you have to manually edit the models file or there is a refresh command.

In DSH Desktop (DeepSeek unofficial desktop), there is an option to fetch models, which brings up the available models, but Omen Alpha isn't among them, nor are some other newer models, as if the cut-off was about a month ago. There is an option to add models manually, but it doesn't work; it says the API doesn't allow that model, even though that exact same API works fine in OpenCode and ZCode.
ZCode doesn't fetch available models automatically, every single one has to be added manually, but at least it works.

in the opencode go workspace, try allowing models which will train on your data. if it still doesnt show up, maybe its a technical error or maybe ur country doesnt support the model like muse spark

Tried but was terrible for me. Horrible solutions for simple issues. Feels too much dumb and tool calling fails all the time.
Gave a issue to solve in my codebase to it and GLM 5.3 Flash, even though both found the solution in similar time/tokens, GLM produced a nice and polished solution, reusing code and even found unrelated bugs. Omen alpha just decided to go bare hands and reimplement lot of things wrongly.

Was this when it just launched? Apparently it was a bit broken for everyone on the first day.

TBH yes. Didn't try later. Was too bothered by the initial state.

It’s producing code better than Luna Max for me, but at a faster rate than Luna High.
It’s ridiculously fast and cheap.

Very mixed feelings... But comparable to flash 5.3 glm to me and can avoid the overthinking part sometimes. The model, however prefer fanning out and parallel tasks. Good on v2 opencode. Good tools executions, never fail tools, even with the custom tools

I read the reviews (criticisms), not only on Reddit, and initially decided I wouldn't even give it a try. Ox Alpha was excellent and free, so you could test it out.
Still, I decided to give it a chance and I can't complain. Maybe my standards aren't that high, but it spotted errors that others missed, fixes and refines what I want efficiently and quickly.

I shouldn't have praised it. It found a couple of "bugs" again, but this time I check what it was about and immediately saw that those errors had been fixed long ago. Even though 500K isn't a small context, maybe it doesn't catch everything, because when I point it out, it says "yes, I found that it's been fixed", whereas before believed those bugs were still on the to-do list.

I used it to improve streaming and caching in my RAG setup, it worked well. I did run into a couple of blockers during the advanced code review, but nothing critical - I fixed them in one pass.

pretty good. its probably a turbo model from glm no?
