The other thing I have matured over the year is not to be that dad that’s too extra on a youth sport game. Being the coach requires me to be more even keel, cuz being the coach I realize I don’t want to be THAT GUY.

@enosarris.bsky.social Would you start Trey Yesavage tomorrow? (Will need to drop Zach Neto to make room; has Caleb Durbin/Chase Meidroth as contingency for short)

@enosarris.bsky.social with Mets losing streak, is this a good time to acquire Edwin Diaz, especially I can keep him next year? My replacement level is Bryan Baker type RP. This is points league that save is more valuable than hold, but hold still score half of points.

With this particular point league scoring, auction calculator using OOPSY projection spit out Butler as #60 batter with 644 PA; Gil would be Jax would be #35 RP & Sanchez would be #120 with 574 PA

@enosarris.bsky.social how good is Lawrence Butler? Good enough to trade away Luis Gil, Griffin Jax, plus a part time bat like Jesus Sanchez? *20 team keeper league that I can reasonably keep all of these players in the next 2-3 years

8/ 🔑 Key takeaway: FlashAttention isn’t about flashy new architectures. It’s about clever engineering that rethinks basic operations for massive efficiency gains. This could shape the future of large language models. Who’s excited for longer-context AI? 🙋‍♂️

7/ Think of it like upgrading from a chaotic workspace to a hyper-efficient system: No more constant shuffling. Everything fits where it needs to. You work faster, smarter, and better. FlashAttention is that upgrade—just for AI.

6/ Why does this matter? Attention is one of the biggest bottlenecks in transformer models like GPT. FlashAttention eliminates this bottleneck, enabling: ✅ Faster training ✅ Longer context understanding ✅ More efficient AI models

4/ Enter FlashAttention. It rethinks this whole process with a simple yet brilliant idea: Process attention in smaller chunks that fit within the GPU's fast memory. 🧩 It’s like solving your puzzle section by section on the small table, no running needed!

3/ AI models face the same problem when handling attention—a mechanism that helps them understand relationships in text. The traditional approach runs back and forth between fast GPU memory (SRAM) and slow memory (DRAM) to compute attention.

2/ Imagine working on a huge puzzle, but your table is too small to lay out all the pieces. You keep running back and forth between the table (fast workspace) and the floor (slow storage) to find the right pieces. 🏃‍♂️ Inefficient, right?

1/ Let’s talk about FlashAttention, a game-changing innovation in AI that’s transforming how models like GPT process information. If you’ve ever struggled with a big jigsaw puzzle on a tiny table, you’ll get it. 🧵👇

I wonder if this was the source of inspiration of @perplexityai.bsky.social name.
Perplexity
Perplexity is a measure often used alongside cross entropy loss to evaluate the performance of models in tasks like language modeling. It can provide a more interpretable way to understand the uncertainty of a model in predicting the next token in a sequence.
Perplexity measures how well the probability distribution predicted by the model matches the actual distribution of the words in the dataset. Similar to the loss, a lower perplexity indicates that the model predictions are closer to the actual distribution.
