@chichengcc @ArpitKalla ...and this is just one of many, many more challenges deploying robots in the real world! Reliability is a full-stack problem

We just hit a weird milestone: our model became more reliable than your average home WiFi. Just like everybody else, we thought cloud inference was the obvious choice. Yet 2 days into the ACT-2 eval, our mind completely changed. If our hero @ArpitKalla didn’t cook, this video wouldn’t exist 🧵

Thanks to @perryzjia and team at @sundayrobotics we can go from a hypothesis to collecting data, train a policy and then evaluate on diverse scenarios all in an hour. This tight loop is all there is. This is the scaling hypothesis for robotics imo
Perry Jia@perryzjia

1/N Two years ago, we recruited our first Memory Developer off Craigslist and onboarded them in a public library. Today, more than 1,000 Memory Developers have helped us build the data engine behind ACT-2. Here's how we got from that library to here 🧵

My favorite shot: 5x5 grid of Memos, all folding at once, all finishing. Hardware reliability work is invisible precisely when it succeeds - that shot exists because we ground through every single failure mode. A fleet where every robot works isn't luck. It's engineering 🦾
Tony Zhao@tonyzzhao

This property allows us to hill-climb performance in our office, and trust those gains to hold in unseen homes Our fleet of Memos runs in parallel to rapidly advance reliability, quality, and speed. Left: fleet-scale improvement in-house Right: Memo working across unseen homes

@tonyzzhao we forgot to connect Memo to the wifi! Oh wait we don’t need it. We moved our robot policy to run completely on-device. Why? Because “works great until the WiFi hiccups” is not an acceptable failure mode for a robot operating in your home. Local inference: predictable latency, no surprises.

@henryzhongsc @tianyi___zhang closely related, but not the same. DFloat11 uses variable length Huffman coding and reconstructs BF16 before matmul. this codec uses fixed width sign and exponent codes with sparse escapes that matmul reads directly.

I removed 423 GB from GLM‑5.2 without changing the model. 1,403 GB → 980 GB. 753B weights. Bit for bit exact. No quantization or retraining. The weights remain compressed in VRAM instead of rebuilding the full model first. Full writeup and repo in the next post.

1/ releasing muse image today — the first image generation model from MSL. it's agentic: pairs with muse spark to reason through your prompt, search the web, and plan before it generates. people get what they meant on the first try. live now in the Meta AI app.

@JitendraMalikCV what do you think about the need of representative benchmarks as well? given there is such a wide variation of hw/tasks/long tail of errors in eval, in addition to the eval maxxing?

SAM 3.1 is a drop-in upgrade to SAM 3 that 2x's video processing speed (16→32 FPS on a single H100) with no loss in accuracy. Previously SAM 3 tracked every object in video with a SAM 2-style masklet, so inference cost scales linearly with the number of objects. To support 30fps inference in practical applications we had to parallelize across multiple GPUs: up to 10 objects on 2 H200s, up to 28 objects on 4 H200s, and up to 64 objects on 8 H200s. There was also no shared object-level context, making it harder to resolve ambiguities in crowded multi-object scenes. SAM 3.1 addresses both these issues through object multiplexing. 16 objects are processed in a single forward pass on one H100 GPU. Shared global context across objects also gives a slight accuracy boost on crowded multi-object tracking scenarios. 👇Try it out and let us know what you use it for!

We’re releasing SAM 3.1: a drop-in update to SAM 3 that introduces object multiplexing to significantly improve video processing efficiency without sacrificing accuracy. We’re sharing this update with the community to help make high-performance applications feasible on smaller, more accessible hardware. 🔗 Model Checkpoint: go.meta.me/8dd321 🔗 Codebase: go.meta.me/b0a9fb

I just implemented inference for Qwen3.5 0.8B based on github.com/maderix/ANE, and successfully ran it on an M1 Pro.

BOOM! Apple’s Neural Engine Was Just Cracked Open, The Future of AI Training Just Change And Zero-Human Company Is Already Testing It! In a jaw-dropping open-source breakthrough, a lone developer has done what Apple said was impossible: full neural network training– including backpropagation – directly on the Apple Neural Engine (ANE). No CoreML, no Metal, no GPU. Pure, blazing ANE silicon. The project (github.com/maderix/ANE) delivers a single transformer layer (dim=768, seq=512) in just 9.3 ms per step at 1.78 TFLOPS sustained with only 11.2% ANE utilization on an M4 chip. That’s the same idle chip sitting in millions of Mac minis, MacBooks, and iMacs right now. Translation? Your desktop just became a hyper-efficient AI supercomputer. The numbers are insane: M4 ANE hits roughly 6.6 TFLOPS per watt – 80 times more efficient than an NVIDIA A100. Real-world throughput crushes Apple’s own “38 TOPS” marketing claims. And because it sips power like a phone, you can train 24/7 without melting your electricity bill or the planet. At The Zero-Human Company, we’re not waiting. We are testing this right now on real ZHC workloads. This is the missing piece we’ve been chasing for our Zero Human Company vision: reviving archived data into fully autonomous AI systems with zero human overhead. This is world-changing. For the first time, anyone with a Mac can fine-tune, train, or iterate massive models locally, privately, and at a fraction of the cost of cloud GPUs. No more renting $40,000 A100 clusters. No more waiting in queues. No more massive carbon footprints. Training costs that used to run into the tens or hundreds of thousands of dollars? Plummeting toward pennies on the dollar – mostly just the electricity your Mac was already using while it sat idle. The AI revolution just moved from billion-dollar data centers to your desk. WE WILL HAVE A NEW ZERO-HUMAN COMPANY @ HOME wage for equipped Macs that will be up to 100x more income for the owner! We’re only at the beginning (single-layer today, full models tomorrow), but the door is wide open. Ultra-cheap, on-device training is here. The future isn’t coming. It’s already running on your Mac. Welcome to the Zero-Human Company era.

🥳 Super excited to share SAM 3 and SAM 3D! SAM 3 introduces two of our most highly requested features for SAM -- open vocabulary text and exemplar prompts! And with SAM 3D you can now go from single image + object masks to 3D textured shapes and scene layout!
AI at Meta@AIatMeta

Today we’re excited to unveil a new generation of Segment Anything Models: 1️⃣ SAM 3 enables detecting, segmenting and tracking of objects across images and videos, now with short text phrases and exemplar prompts. 🔗 Learn more about SAM 3: go.meta.me/591040 2️⃣ SAM 3D brings the model collection into the 3rd dimension to enable precise reconstruction of 3D objects and people from a single 2D image. 🔗 Learn more about SAM 3D: go.meta.me/305985 These models offer innovative capabilities and unique tools for developers and researchers to create, experiment and uplevel media workflows.

@mvpatel2000 Anything to do with image size being 128x128 or higher after around 80k iteration due to the Progresize Resizer. And using resent 50 which half’s the image width and height 4 timesm due to stride 2, 128 is the factor of 32 above 100 (the starting width height), so don’t lose info

Wanted to release Composer v0.14.0 last night, but my CI/CD cluster got airstriked. I'll give a little prize if anyone can correctly identify what causes this curve. Hint: It's an intentional artifact of a training algorithm

The success of ChatGPT shows the power of Reinforcement Learning from Human Feedback. In this paradigm, models are aligned to values using a "reward model" trained on human preferences. I argue that it is imperative these reward models be open source: lesswrong.com/posts/nTy48zvB… 1/

After 3yrs of locomotion research, we report a major update in our #CoRL2022 (Oral) paper: vision-based locomotion. Our small, safe, low-cost robot can walk almost any terrain: high stairs, stepping stones, gaps, rocks. Stair for this robot is like climbing walls for humans.
