What a week at @NVIDIAGTC. New partnerships with @Teradyneinc, @Universal_Robot, @nebiusai, @nvidia, @cevalogistics, and @Zalando. Cortex live on the floor handling shoebox returns, and a spot in @JensenHuang’s keynote. All while shipping more robots than ever. #GTCBerlin

Excited to collaborate with Sereact and Otto Group to tackle the complexities of logistics. 🦾
The first 10 Sereact dual-arm robots will be deployed at @OttoGroup_Com's logistics center in Poland to grasp, identify, assess and sort returns, including items they’ve never seen before. 15 more are planned in phase two, bringing the program to 25. This is what the future of physical AI looks like. Full announcement in the comments.

Online shopping returns are one of the hardest warehouse tasks to automate. Here is why. 👟 Sereact’s AI-powered dual-arm robots can handle returned shoes, clothing and mixed items, even when packaging is messy or products arrive in unfamiliar conditions. Powered by Cortex, the system combines visual understanding with robotic manipulation to identify, grasp and sort items without requiring individual training for every product. The technology is already operating at Zalando returns facilities in Germany and Poland, with CEVA Logistics. 🏢 Companies: @SereactAI , @Zalando & @cevalogistics 🤖 Robot hardware: @Universal_Robot 🎥 Media: Raphael Levy — demo at @NVIDIAGTC Berlin 2026 ⚠️ This content is shared for informational purposes only.

Cortex is built on @NVIDIA’s physical AI stack. Sereact uses NVIDIA Isaac Sim and NVIDIA Isaac Lab to turn real picks from the returns line into thousands of simulated variants, and NVIDIA Cosmos world foundation models to re-render them across garment states, packaging, materials and lighting.

New policies are post-trained on @nvidia Blackwell GPUs and tested against held-out cases before they reach the robots. When a robot struggles with an item, the fix can come back as a tested update within days instead of weeks.

Incredible evening at the Zürich Robotics Roundtable. Thanks to Yves and @oier_mees for joining me on stage, and to @edozurich, Gianmaria and Roboto AI for hosting. Packed room, great crowd, lively conversations. The moment for physical AI is here. Let’s go! 🦾

That’s what happens when you play with our robots. Team. So proud!

Shared from GTC with the @creandum team what’s new at @SereactAI but it deserves more eyeballs. Company had 2 phenomenal quarters back to back and now fully upgraded from VLAM to world action models. Khiem is a legend. Went from intern to AI research lead and serves @TuscherMarc & the gang for +4 years. Only worry: my sleep over office mattress setup after the board meeting this week got a little too fancy over the years…

Two days at Nebius House in Berlin! 😮‍💨 In one room we had @TuscherMarc from Sereact with the one and only @evanhelda. Jacek Golebiowski from distil labs on open models and post-training. Zeev Farbman from LTX on going from video models to physical AI, and many more awesome folks! I also got to feature in a short segment on the Nebius Live broadcast. Thanks for having me, that was genuinely fun. Also, great hosting by @dee_bosa! Look at that mix. Video generation people, post-training people and robotics people, all turning up under the same label. Two years ago those were three different conferences. That convergence is the thing I keep writing about, and it was just sitting there in the running order. Mostly though, the people. So many good founders building in robotics right now, and the best conversations happened between the sessions rather than in them. More from Berlin soon! :) 🇩🇪 @NVIDIAGTC / @nebiusai Also great to run into some friends @MarkieshaTweets, @demian_ai 🦾 ~~  ♻️ Join the weekly robotics newsletter, and never miss any news → ziegler.substack.com

Automating fashion returns is complex because every return arrives in a different condition. We have teamed up with @nebiusai, @nvidia, @SereactAI and @Zalando to deploy a closed training loop that solves this in live logistics operations. ➡️brnw.ch/21x6B0p

This is Cortex handling @Zalando returns at a @cevalogistics fulfillment center in Germany. It’s live and in production, every shift.

When we started @SereactAI , people told us returns were impossible to automate. This is Cortex handling @Zalando returns at a @cevalogistics fulfillment center. It’s live and in production, every shift. Proud of the team that made this real.

Physical AI was centre stage at @JensenHuang 's #GTCBerlin keynote today. Proud to see Sereact among the model builders on @nvidia Isaac.

Real customers. Live orders. Production at scale. We’re teaming up with @Teradyneinc and @Universal_Robot to run Cortex on UR cobots. Hundreds of robots shipped across Europe, and now heading to North America. See it live at the @nvidia booth, Hall 3. #GTCBerlin

The innovation extends across Europe’s robotics ecosystem. 🤖 @ABBRobotics, @FlexionAI, @HexagonAB, @TheHumanoidAI, KUKA, @NEURARobotics, @SereactAI, and @Universal_Robot are among the partners building on NVIDIA’s open robotics platform to advance autonomous robotic systems.

The robot messed up the fold. Then folded it correctly. No one taught it that. Check out the new research from Sereact.
Robots that learn by copying people hit a ceiling. Cortex 2.6 now learns from practice: after 50 attempts per task, its success on three returns-handling tasks rose from 60–70% to 85–100%.
