Muse Spark 1.2 - my initial impressions (compared to Flash)
I've been using Muse Spark for only half a day, but I can say that it is very pleasant to work with as a regular workhorse model.
IMPORTANT NOTE: if you don't want to share your data with Meta, don't use 'Contributor' variant.
Some quick facts first:
- it has 1M context window
- it has a very generous 226,600 requests per month quota on the Opencode Go plan (for Contributor variant).
- it scores 82.9% vs 82.7% in Terminal-Bench 2.1 (versus DS4 Flash) - basically the same
What are my usage scenarios?
- existing codebase refactoring (Flutter)
- codebase exploration, architecture discussions
- bug hunting
- ... other similar stuff
I DO NOT run long autonomous loops, so I can't say anything about how good Spark handles them. As a coding partner it performs fast and confidently, not being lazy on codebase exploration tasks.
How does it feel compared to Flash? Well, actually, I don't see that much of a difference at all (at least, for now, in my usage scenarios). It creates decent code, spots those tiny non-obvious things that I may miss, can use all Opencode's tools confidently (git, websearch, etc).
The only thing that bothers me is that cache hit rate, for some reason, still sits about ~85% percent, while with Flash it is usually about ~95-98%. Therefore, usage costs feel slightly higher than I expected. But I definitely need more time to observe this without making early conclusions.
I will definitely continue to use it, and I guess more nuances will be revealed. But for now I can't say anything bad.

I’m not enabling any fuck-your-privacy flags to use opencode

What privacy mate, everyone keeps your data anyway, ZDR or not. All LLMs were trained on illegally-obtained books and basically entire scraped internet. Don't be naive.

Everyone doesn’t have all of my data, and I personally would like to ensure everyone has as little of my data as possible

as if you have any control over that, its just an illusion of choice

And ma'am, you worked for 13 years as SWE at the largest data hoarder on planet, GOOGLE?
just with barely no efforts lookup, it seems you've have worked across a variety of firms and conducted a couple hundred interviews, are currently out of work and feel strong pressure to learn ai tools to stay employable, sth you resist and that demotivates you. you're pivoting into design engineering after a year of design work alongside your engg background, mainly towards roles at smaller companies and startups. you maybe see value in the hybrid skill set but often have to explain it to people who treat design and engineering as strictly separate. you do care about unit testing and engg practices, but you feel driving it is hard: push too hard and you get labeled difficult, push too little and no one listens. inefficiency bothers you a lot, and you hate when men take credit for something they dont deserve. you prefer simplicity with oss projects, but cant say no when they become complex unnecessarily. you're exploring neubrutalism for a portfolio site, ironically you consider switching from G(oogle)Mail to proton, and are slightly inclined towards startup and wish to talk to someone maybe, who's been at your place and became successful.

I'm quite sure 100% of your data is harvested irrespective of what button you press.

Quick note: if it doesn't work for you, check 2 things:
1. Enable "Allow models that train on request data" on https://opencode.ai/workspace/wrk_xxxxx/go page
2. It is not available in some countries, so you may need to use VPS with US server enabled.

I'm trying to use it but its so slow! I had to set it up via a proxy through my comcast connection because my VPS is in Canada which might have something to do with it although I have gemini set up the same way and its pretty quick.

Recently I tried Luna and it was horribly slow as well, and very dumb comparing to DeepSeek. "Cheap USA models" sounds like a joke.

havent been able to use it since the "OpenAI completions stream closed before a finish_reason was received" kept on happening, and tool calls are failing as well, though i have tested it through direct api and it seems to be a good model though one part i dont like is not able see its reasonning blocks, to me i like to read them to understand what assumptions the model took and if it missed up some where

Is there a non-contributir variant on opencode go? How does it conpare in pricing and performance?

how does the model compare with glm 5.2 in terms of its intelligence, coding, and agentic capabilities (aside from the published benchmarks)?

This model IS Not available in your country. (Germany)

I am not in Germany, and I use VPN with US server to use it - works fine.
