Arena API Bridge 3.3.0

LMArena Script version 3.3.0 with updated backend

Full release due to multiple changes needed to make the script work again, since it'll no longer work correctly with older or different backend scripts. At least it's all translated now for all you retards who couldn't read and follow step-by-step instructions due to chink speak ;-)

Legacy version 3.2.7

Full LMArenaBridge zip package with Arena 3.2.7 Script

Arena API Bridge Tampermonkey Script

No pass for both since this src is scuffed AF and somehow has outlived numerous proxies and scripts (lol looks like it's run of luck ias finally coming to an end), so I no longer care about gatekeeping this shitty script. Expect more updates assuming LMArena doesn't completely cuck their site behind a login wall. Arena just removed Opus and GPT 5.4 access for both Direct and Side-By-Side chats. While they intend to "being these models back in a wat that's more sustainable when possible", it isn't looking good, and while I can still send messages through the script, I'm not sure how much longer that'll last. I'm not declaring the script dead just yet, but if it turns out to be permanent, i'm ending development of the script.
