We did a comparison study on where a robot's intelligence should live by using the same model (OpenAI GPT6-Astra), same bimanual YAM station, same LEGO pick-and-place task, all run on SE3' real-world remote eval stack: 1. Frozen code-as-policy (built on NVIDIA ENPIRE components): 6/20 placements 2. Agentic control +... show more

Here’s how the two approaches worked: 1. Code-as-policy: Astra wrote and tested a Python policy, which we then froze for evaluation. The policy ran without further model calls. 2. Agentic control: Each episode started with a fresh Astra session that read camera snapshots and issued commands through a control harness.

Getting hold of the brick wasn’t enough. What mattered was robustness and recovery. The code-as-policy lifted the brick in 14/20 episodes but completed only 6 placements. In the other eight, it stopped before reaching the release pose or held the brick without releasing it. Agentic control completed 18/20 placements. Nine required grasp retries, including one that recovered from a drop.

The agent recovered from its own misses: 9 of its 18 completions needed more than one grasp. In episode 8, it missed five times, lifted on the sixth, dropped the brick, reacquired it and released at 419s. The code-as-policy never made a second grasp attempt.

Agentic control completed more placements, but successful runs took longer. Among successful episodes, median time to release was 131 seconds for code-as-policy versus 175 seconds for agentic control. Agentic control also had more time to recover: up to 600 seconds, compared with 180 seconds for code-as-policy. The timing gap reflects more than model reasoning alone.

@OpenAI @se3labs @nvidia Keeping the model in the loop lets it adjust each movement from live feedback, rather than letting errors compound through a fixed sequence of actions.

GPT-6 Astra vs Claude Opus 5.5 (both on High) Same prompt. A storm inside a bottle, built from scratch in Blender, all code, zero assets. - Astra: 24 min, ~$6 - Opus: 82 min, ~$18 Was Opus worth 3x the price?

Astra vs Fable 5 : Jump is same like opus 4.8 to fable 5 in quality side by side comparison on same prompts , this is why i am super hyped for openai < astra is the path to the bell of AGI iykyk>

π0.5 vs. MolmoAct2. Same task. Same object placements. Same training data regimen. Precise spatial placement lets us compare models side by side on any matching rollout in our Reality Check benchmark. Someone jokingly called it “Model Smash.” 👇 1/3

SITUATION EXPLAINED: Grok 4.7 beats GPT-6 Astra on real-world tasks, and it's 5x cheaper. • Same price as 4.6, $2 input and $6 output per million tokens, well under Sol, Fable, and Astra • A new larger base model, which Elon has put at 2.1 trillion parameters, up from 1.5 trillion, with extra training on SpaceX data • Trained to natively understand the Grok Bot harness, the same move Anthropic made with Claude Code • Leads on electrical engineering and Harvey's legal benchmark, beats Astra Max on GDPval, trails on software engineering • Elon Musk: "Grok 4.7 places SpaceXAI as third after Anthropic and OpenAI for agentic coding. When factoring in that Grok is significantly faster and lower cost, it's a great choice for your everyday workhorse" Theo Jaffee: "SpaceX has a huge amount of data on real world hardware problems, real world engineering. So I bet Grok models are going to be better at rocketry engineering than any of the other models out there."

Sachin Katti says OpenAI had Astra optimize its own inference on NVIDIA's Rubin chip, adding another 2x in 72 hours "It's a testament to NVIDIA's hardware that out of the box we got a 3x improvement in throughput. We literally took the same code that we had optimized for Blackwell, ran it on Rubin, got 3x improvement." "Then, can we actually make Astra run agents using Astra as the base model, go optimize this inference of Astra itself on Rubin? It's a recursive loop. The model is figuring out how to optimize its own inference serving on Rubin chips, and over 72 hours the model produced another 2x improvement on the throughput." "Things that would take weeks, if not months, to optimize in the past, we now are getting models that are very capable of actually producing over a weekend." _______ Link and more from Sachin Katti's conversation:

1. Sam Altman on Will All Startups Be Killed by OpenAI There are 2 strategies to build on AI right now: Assume the model won’t improve. Assume OpenAI will stay on the same growth trajectory. 95% should bet on #2. We have a mission to improve the model, so we will steamroll you.

Liquid AI's head of post-training explained how they built a small model that runs on-device under 1 GB in 20 minutes - better than $2500 small-model bootcamps. pick LFM2.5 base -> on-policy preference alignment -> agentic reinforcement learning -> curriculum training -> iterative model merging -> ship a 1B model that reliably calls tools on your phone. That loop is why frontier small models now beat 70B models on the tasks that actually matter. LFM2.5 + on-policy DPO + agentic RL + curriculum training + iterative merging - that's the stack. Watch and save it, then run a 1B agent on your phone tonight.

Someone tested Union-Alpha, the new stealth model on OpenRouter, with their usual shooter prompt and it built a full playable FPS. The menu alone gives it away: huge title, orange arrow button, dark 3D scene, the exact same look as GPT-6 Astra. Feels like OpenAI is behind.

NVIDIA just revealed MotionBricks, a new AI model trained on more than 350,000 motion clips. What’s really impressive is that the same model can animate a digital character and control a humanoid robot in the real world.

Muse Wonder might beat Astra on benchmarks, but it's nowhere close to Astra on taste. Same prompt: - Wonder (xhigh) = $2.42 in 20 min - Astra (low) = $2.19 in 7 min Benchmarks don't tell you everything 😬

Opus 5.5 vs GPT 6 astra tested both with the same prompt at their highest reasoning settings, using the same devin harness: > opus took 2 hours 10 mins and cost $75 > astra took 1 hour 25 mins and cost $61 opus 5.5 attention to details is on point, it took time to make everything perfect as i wanted but still super slow and ended up costing way more then astra which one did better here?

Same prompt for all 4 tests, 100% code generated animation. GPT 6.1 Sol vs GPT 6 Astra vs Sonnet 5.5 vs Opus 5.5 Despite the huge price difference between the final results, if this was a blind test, we would not even say that Sol and Astra are on the same level as Sonnet and Opus. On price, Sol was much cheaper than all other models, and maybe even better than Astra quality wise. On quality alone, Opus and Sonnet were above (by a lot), including richer details, camera movements, effects, being more fluid and engaging overall. And if we consider Price and Quality, Opus is the overall winner, costing 12$ vs 18$ from Sonnet, finishing in 1h and 16m vs 1h and 36m.

Everyone was calling Fable5.1 the ceiling. Then GPT-6 Astra rendered the same scene. The bottom half is the file both models were handed. Crash dummies, no materials, no light, no faces. The top half is what each one built from it. GPT-6 Astra goes first. Fable5.1 goes second. Same seats, same sunroof, same autumn road. Watch the belt on the shoulder and the light through the glass. One model lit a car. The other remembered a drive. You will not need the label to know the second it switches.
