Could open source models be the key to affordable and efficient news recommendations? @helloheld's article explores that while LLMs have strong predictive power, they come with high costs and slow speeds. #LLM towardsdatascience.com/making-news-re…

Optimizing recommendation engines is no easy feat. With costs high and response times slow, LLMs face scalability challenges in news platforms. However, refining prompts and using additional user data could unlock significant improvements. Read @helloheld's latest article now. #LLM towardsdatascience.com/making-news-re…

@h_i_g_s_c_h Embeddings come from OpenAI. Dimensionality reduction and clustering done internally by Nomic.

@helloheld What kind of embedding is it? UMAP or tSNE?

Concrete will stand the test of time, hopefully

It's been a while since I've tested Midjourney. The outputs these days are pretty impressive. abstract—
