Hi Joseph and Arzam,

Thanks for the invitation! Caipora would be glad to take part in MCEC Season 3.

A static Linux aarch64 (musl) build of Caipora 3.8 is attached to the release: https://github.com/ComputecOrg/caipora/ ... s/tag/v3.8 (caipora-3.8-linux-aarch64-musl). It is a single binary with the network embedded, and it reproduces the same bench signature as the x86-64 build (5263766), so it plays the same search. UCI options: Hash, Threads, Move Overhead, Ponder.

Caipora is an original Rust NNUE engine from Brazil; the code is written by Claude Code (AI) under my direction, as declared in AI_USAGE.md in the repository.

If anything misbehaves on a device, just let me know and I'll fix it quickly. Good luck with the new season!

Hi Joseph and Arzam,

Hi Zigoto,

Thank you for accepting our invitation and for joining the tournament. We are grateful for that and we are excited to see how Caipora will perform as its the same as Coda which is the code is written by Claude under human direction.

For Caipora originality, I look first on Caipora repository and read its originality before I tell arzam to finally invite Caipora. Caipora is same as Coda (if you aware of this engine), also Triumviratus and ZigQueen whom use AI Assistant.

Arzam runs the tournament and I am the who maintain this thread and for looking for new participants, I just found Caipora 3.8 here in talkchess. I made a judgement for its originality if its clean/not a derivates, I found it as it's a original engine

We preserve Caipora for the incoming Season 4 new comer as season 3 is ending and its nearly in its final stage. You will finally see Caipora playing exactly at the very very beginning of Season 4 againts the fellow new comer engines.

Once again, Thank you for joining.

Stay tune.
Joseph.
