What Hacker News says
4 sourcesWell it's cool that they released a paper, but at this point it's been 11 months and you can't download a Titans-architecture model code or weights anywhere. That would put a lot of companies up ahead of them (Meta's Llama, Qwen, DeepSeek).
Closest you can get is an unofficial implementation of the paper https://github.com/lucidrains/titans-pytorch
In Google Titans architecture, helping AI have long-term memoryFWIW, Phil Wang (lucidrains) has been working on Titans reimplementation since roughly the day the paper was released. It looks to me from the repository that some of the paper's claims have not been reproduced yet, and reading between the lines, it might be Wang considers the paper to not be that groundbreaking after all -- hard to say definitively but the commit speed has definitely slowed down, and the last comments involve failing to replicate some of the key claims.
Unfortunately. The paper looks really good, and I'd like for it to be true.
