It's clearly AI.

I’m struggling to see the value here. At $50, this seems hard to justify given the availability of cheaper, well-supported options like MuziWorks Duo, Ebyte, and other newer LR1121/LR2021-based designs. Those chips offer both 2.4 GHz and sub-GHz support in a single modern package, often at roughly half the price, which makes the SX1281 feel fairly outdated.

Nvm, looks like AI scam.

Sounds like bs. Why would someone pay $50 for almost 10 years old hardware when there are plenty of well-supported and cheaper options like MuziWorks Duo / Ebyte / etc with newer LR1121 or LR2021 which combine both 2.4G and SubG bands in single and modern chip at 1/2 of the cost less? SX1281 and SX1281 are relics.

Is this whole post and github repo LLM-generated slop?

H3 is preferred for geo analytics because it produces a more uniform spatial index with low distortion and consistent distances between cells

Its primary use case was efficient spatial aggregation for applications like pricing, demand forecasting, positioning etc.

You may get way more accurate results from relatively small models as well as logits for each class if you ask one question per class instead.

Likely not, embeddings are very crude. Embeddings of a text is just an average of "meanings" of words.

As is embeddings lack a lot of tricks that made transformers so efficient.
