what I implied is that in 2024 a lot was written about RAG, LLMs were trained on it, and that explains your gpt-4o-mini reference. the argument is that the article is ai slop, and that point is totally unrelated to name dropping fortune 500s references
Re:RAG Is Simpler Than You Think on Wednesday August 26, 2026 @09:49AM (#49449141)
the biggest giveway is actually not the writing style, but the content

"using GPT-4o-mini for query rewriting" -> model from 2024, when RAG was trendy, and all the langchain, llama-index, etc, docs mentioned this specific model

cool! you might be interested in graphchi (2012), also designed to do large scale graph operations on a single machine

there was a project trying to achieve some of those goals a few years ago using p2p: petals https://github.com/bigscience-workshop/petals

their bloom model was also a collaborative effort https://huggingface.co/docs/transformers/en/model_doc/bloom

AI agents are still a pretty big topic in crypto, a lot of projects doing what you described. did you try https://github.com/ccxt/ccxt
Semantic Web is now revived into its new marketing incarnation, called Knowledge Graphs. There's actually a lot of work on building KGs with LLMs, specially in the RAG space e.g., Microsoft's GraphRag and llama_index's KnowledgeGraphIndex

To train small gpt-like models, there's also aitextgen: https://github.com/minimaxir/aitextgen

Ableton Live has a Audio to Midi [1] feature that works pretty well to extract notes from audio. Melodyne [2] is a very powerful tool to mess around with notes in general.

There's also some open source projects out there, such as aubio [3] and Omnizart [4].

The screws have a very easy direct access, I can see them being repurposed for other means with a bit of effort.

The keyboard is a little small, and does take a bit to get used. Not recommended for big fingers.

Battery life is pretty good; I charge it at night, and usually is half-battery. My usage is pretty decent, but mostly on wifi.

Just noticed they have a new version with android 10: https://cubot.net/Smartphones/KingKong-mini-2

I have been using a Cubot Mini (4") for sometime now (1+ year), and am pretty happy with the experience overall. Feels so good to have a phone that fits in any pocket.

The field of Open Information Extraction has been trying to do that in a generic way for a long time, but the results are still far from good. A few references: OpenIE [1] Graphene [2] MinIE [3].

If you already have a Knowledge Graph (KG) and want to populate its instances from documents, that's called KG Population, and Knowledge-net [4] is a good reference.

Relation Extraction is another interesting approach if you know which kind of relations you're interested in, OpenNRE [5] a good example.

NMF works great for unsupervised audio source separation, e.g. [1]. See [2][3] for a good overview of the field.
