Is anyone actually using 5.6 Sol with light or medium effort? What’s the difference between high and extra high effort?

@OpenAI’s new voice mode is so much better, a lot less interruptions

[NVIDIA AI Infrastructure @NVIDIAAIInfra]

We swept every benchmark in MLPerf Training 6.0 as the only platform to submit on all models and frameworks.

✅ DeepSeek-V3 (671B MoE) trained in 2.02 mins on NVIDIA GB300 NVL72 systems on @CoreWeave
✅ Llama 3.1 405B trained in 7.07 min on NVIDIA GB200 NVL72 systems on @Azure
✅ DeepSeek-V3 throughput improved 1.3x in just 3 months through software alone

Extreme co-design, scale-up and scale-out networking, software optimizations, and high resiliency enable the fastest time-to-train for frontier model builders.

@eliebakouch Thank you!

@elonmusk What percent of code is in C? Also…PP is brutal to optimize

@deepseek_ai v4 is 1.6T parameters 🤯

Odyssey is cooking 🔥

[Odyssey @odysseyml]

It’s time to go beyond language models.

Introducing Odyssey-2 Max, our most powerful world model yet. It materially advances the SOTA in physical accuracy.

This is a big step toward models that simulate and interact with the world in real time.

A new intelligence entirely!

@aaronistan What does “higher quality completion” mean when it pertains to folding clothes?

@martin_casado Operating System Concepts, by Silberschatz. Used by 15-410 at CMU, hardest class I ever took!

[Philip Petrakian @pgpetrakian]

I don’t understand why there’s so much focus on getting robots to run. Why not focus on real-world tasks?

[Philip Petrakian @pgpetrakian]

@Mikesfriend @BenjaminDEKR As a non-expert in robotics I would say it’s two distinct challenges, requiring very different types of movements. But maybe what you learn from running can be applied to folding laundry?

[Philip Petrakian @pgpetrakian]

@BenjaminDEKR I’ve learned with my @maticrobots that it’s ok if the robot completes a task a lot slower than a human would. I’m at the office all day, I just want the tasks completed before I’m home.

2026 might go down as the best movie year ever:

- The Odyssey (directed by the GOAT Nolan)
- Dune: Part Three
- The Mandalorian & Grogu

If only The Batman Part II wasn’t delayed to 2027…

@Txz67 @ScottWu46 @antigravity Doesn’t that mean their coding agent needs improvement 👀
