These thoughts after working on suspenseful story generation (pre o1) arxiv.org/abs/2402.17119. GPT can be beat at suspense generation. Interestingly GPT can be improved by guiding it with the theory of-mind part of story b planning. ~3 pages is the longest form we’ve tried.

Creating Suspenseful Stories: Iterative Planning with Large Language Models
Automated story generation has been one of the long-standing challenges in NLP. Among all dimensions of stories, suspense is very common in human-written stories but relatively under-explored in AI-ge...

Something I don't understand is: why can't LLMs write novel-length fiction yet? They've got the context length for it. And new models seem capable of the multi-hop reasoning required for plot. So why hasn't anyone demoed a model that can write long interesting stories? I do have a theory ... +

Great blog post (by a 15-author team!) on their release of ModernBERT, the continuing relevance of encoder-only models, and how they relate to, say, GPT-4/llama. Accessible enough that I might use this as an undergrad reading.

With students writing my theory exam today, I figured it's a good time to share a link to my open textbook with all you current (and future!) theoreticians. This term was the first time I used it in class, and students loved it. Big plans for future editions, so stay tuned! taylorjsmith.xyz/tocopen/

A timely paper exploring ways academics can pretrain larger models than they think, e.g. by trading time against GPU count. Since the title is misleading, let me also say: US academics do not need $100k for this. They used 2,000 GPU hours in this paper; NSF will give you that. #MLSky

$100K or 100 Days: Trade-offs when Pre-Training with Academic Resources
Pre-training is notoriously compute-intensive and academic researchers are notoriously under-resourced. It is, therefore, commonly assumed that academics can't pre-train models. In this paper, we seek...
