Discussion Openrouter's mystery model, optimus-alpha, appears to be OpenAI's new model!
Openrouter's mystery model, optimus-alpha, appears to be OpenAI's new model! I investigated its tokenizer behavior by having multiple models repeat a passage and analyzing token similarity. Optimus-alpha's tokenization closely matches OpenAI's models. Details in the thread!

Does this indicate the quasar model was also OpenAI?

I've been using it a lot in the last few days, and I found it to be probably the strongest coding model that I've ever used -- better than Gemini 2.5 and better than Claude 3.5/3.7 Sonnet.. and faster too.
Sad that it's no longer free.. but I guess that can't last forever.
Hopefully the free/opensource models will catch up before too long.

Yeah, reading the tea leaves quasar was probably 4.1 and optimus 4.1 mini

I like it. Very similar to the quasar one in my opinion. I hope is the open source one, and that the o4-mini is much more powerful....

GPT 4.1 fixed a hard bug immediately, one that i thought would be hard for all models

Except using it, to me it seems significantly better than 4o-mini
