Researchers have unveiled SUmmarization augmented Policy Optimization (SUPO), a novel RL framework that empowers large language models to handle complex, long-horizon tasks by using LLM-generated summaries for effective context management. https://arxiv.org/abs/2510.06727

The same logic applies to fashion: instead of buying expensive clothes to look better, invest that time and money into getting fit, you’ll look better than anything designer labels can offer.

Here I am. Once again. I'm out of archaeologists.

We matched 576 groups w/archaeologists, leaving 13 groups unmatched. This brings me pain! We've never run out of scientists like this before. 598 requests for one category is A LOT. But still.

Archaeologists 🥺

I’m someone who thinks AI is a powerful art tool for humans, but the trump admin has been shoveling out lazy, low quality AI generations, which tarnishes the whole field

Matt Novak @paleofuture.bsky.social · 10h

Trump launched the TrumpRX website today.

It has a photo of Trump and an AI-generated family with too many fingers and mangled toes.

TrumpRx Is a Narcissistic, AI-Generated Nightmare

AI art really has become the aesthetic of grifters and fascists.

GAGA-1 just dropped: an AI “actor” that fuses voice, lipsync, and performance.

It’s not fully free—there’s roughly 60 seconds of free generation per month; the API is currently unavailable. It’s built for dialogue-driven scene prototyping.

On one hand: don't anthropomorphize AI. On the other: LLMs exhibit signs of gambling addiction.

The more autonomy they were given, the more risks the LLMs took. They exhibit gambler's fallacy, loss-chasing, illusion of control...

A cautionary note for using LLMs for investing without guardrails.

someone got 473 tok/sec(!!) on a macbook M3 Ultra for Qwen3-30b-a3b

and that’s a decent model..

Three line charts showing performance metrics for Qwen3-30B-A3B-4bit running on an M3 Ultra (512 GB RAM) across varying batch sizes.

⸻

Top Chart: Prompt Tokens per Second
• Y-axis: Prompt TPS (tokens per second), X-axis: Batch Size.
• Values rise slightly overall:
• 0: 2876 5: 2868 10: 2880 15: 2885 25: 2893 30: 2891
• Peak performance: 2893 TPS at batch 25, showing stable prompt throughput across batch sizes.

⸻

Middle Chart: Generation Tokens per Second
• Y-axis: Generation TPS, X-axis: Batch Size.
• Throughput improves steadily with larger batches:
• 0: 108 5: 249 10: 336 15: 425 25: 453 30: 473
• Performance scales efficiently, plateauing near 473 TPS.

⸻

Bottom Chart: Peak Memory Usage
• Y-axis: Peak Memory (GB), X-axis: Batch Size.
• Memory grows roughly linearly with batch size:
• 0: 18.28 GB 5: 19.46 GB 10: 21.66 GB 15: 23.28 GB 25: 24.89 GB 30: 26.50 GB
• Peak usage: 26.5 GB at batch 30.

⸻

Overall: Prompt throughput remains flat, generation throughput scales well, and memory usage rises linearly with batch size.

UserLM-8B: an LLM that mimics a person

Microsoft fine tuned an LLM to respond as the user instead of as an assistant

This is useful anytime you need mock user input. like maybe for testing agents, or training models

I would like to share some work we've been doing at cascadetech.ai: Predicted Outputs in vLLM. If you aren't familiar with PO, it allows you to dramatically speed up generation when you know something about the contents of the output (think: code modification).

This is a shrewd email from the guild. They’re asking what prompts they are using for ai review

I’ve long advocated that the best ai regulation is to know what the system and task prompts are, and training data metadata

New: The WGAE, which represents some parts of CBS News including its social team, sent a note to members today advising its members not to respond to Weiss’ request for an email by next week. The union also said it asked CBS for more information about Weiss’ request.
