I tried Muse Spark 1.3 for a while because it's so cheap, but it's definitely in a lower league than Astra, Opus 5.5 and Argon. Still produces slop if you try and vibe code with it, whereas the more capable models write good code.

But does it play doom? /s

PS: I might need to do a doom benchmark, that’d be fun https://playground.jeffyclassify.com/#doom

Tech people really are drug addicts. Rant about Zuck and Meta for 364 days a year and then jump over each other to be first in line the moment he shows something shiny.

great, I've been reading series of papers related to open source/open weight LLM Backdoors.

It's 100% possible, curious when will be the first incident.

Having something built by entity with HQ in the wester world is always a bit safer. That could be mistral, but they decided to be a consultancy company, not an ai lab.

As an aside I really wish people would stop naming their new software projects “Spark” given how many things already use that name.
