LFM3 Omni vs GPT6 Astra - chess edition? we put the LFM (@liquidai) model that @manoletre finetuned for chess, head-to-head up against GPT6-Astra. Astra ran with reasoning enabled and took on average over 100x longer than LFM on every move. @liquidai FTW πŸš€
I adapted @liquidai's d1-omni-600b to play chess and listen to my voice and I haven't been able to beat it. It was the final result of a lot of experimentation and a lot of fun. To me the highlight was after training, asking claude to try experiments to reduce the time the model needed to make a move, peak memory usage, size of the model file, etc *while* keeping chess performance constant. Claude found some cool stuff. For example that only ~2k tokens were being used and that we could get rid of a large portion of the embeddings matrix. Play against the model on my website! πŸ‘‡πŸ½ It runs completely locally on your browser's tab.

Today @WSJ covered our work with @MercedesBenz. our flagship LFMs are now rolling out in vehicles in North America, running directly on the hardware inside the car to power in-car assistance! 🌊 this is one of the first deployments of local generative AI in the real world at scale! ✨ seeing our technology become part of someone’s everyday life is one of the most rewarding feelings of building Liquid. years of work become a small, useful part of someone’s day. they don’t need to know which model is running. they just need it to understand them and work seamlessly. this is really hard and it took us years of fundamental work from first principles to made happen with a brilliant team of engineers from Mercedes and Liquid. I believe on-device AI will fundamentally change our relationship with the technology around us. embedded AI is about change of ownership. With Mercedes-Benz, we are now in production and are building toward deployment at scale. The on-device AI revolution is taking shape in products people actually use, and I’m proud that @liquidai is helping lead it. To our team and our partners at @MercedesBenzUSA and HQ: thank you for the care, persistence, and trust it takes to make this real. It feels good to see the work out in the world. wsj.com/cio-journal/mercedes…

Please just ask Astra to use Antidoom instead, it's 100x cheaper and faster.
We asked GPT-6 Astra to edit Qwen3.5-0.8B weights to improve math. It directly changed only 0.016% of weights, fixing 0.8B's reasoning loops & improving math up to 6x and even instruction following 3x, without gradients or training. We call this Weight-Space Programming: frontier LLMs can now natively read/write neural network weights! 🧡 Blog: rikiyat.github.io/blog/weigh…
Readers added context they thought people might want to know
LLM was given weights explicitly as text in prompt and used code/forward passes (per authors' logs) to ablate Qwen looping direction, a known thinking-mode issue per model card. Primarily fixed repetition in that mode, not general 'natively' improving weights/math. rikiyat.github.io/blog/weight-sp… github.com/RikiyaT/lm_und… huggingface.co/Qwen/Qwen3.5-0… huggingface.co/RikiyaT/Qwen3.…

Two billion parameters, three ways to act: planning, navigation, and manipulation - excited to share some of our latest work along with our new model family. 🐘🐘🐘
Replying to @liquidai
π™»π™΅π™ΌπŸΉ-πš…π™»-πŸΈπ™± can also serve as a foundation for robotics. We explore three adaptations spanning the robotics hierarchy, from tool-based task planning to navigation and manipulation. Tool orchestration: ground objects by pointing, measure them with depth tools, call motion planners, and check outcomes in new camera images. Pair it with a fine-tuned d1-2B skill monitor to detect failures and guide recovery. Navigation: translate route instructions and a sequence of image observations into visually grounded waypoint trajectories. The model achieves 53% success on R2R and 43% on RxR in unseen scenes under strict continuous-control evaluation with wall sliding disabled. Manipulation: turn images, language, and robot state into multi-step action chunks in one forward pass. Jointly trained across 15 embodiments, the resulting VLA achieves 96.2% average success across the four LIBERO suites and 45.7% on RoboCasa-GR1 tabletop tasks. The manipulation VLA generates action chunks in under 50 ms on an @nvidia Jetson AGX Orin using TensorRT in FP16, enabling real-time action generation on embedded hardware. 10/

RIPL optimizes the full path from request arrival to a complete generated response. As traffic rises, its performance advantage is greatest on the slowest requests. Let’s see some production use cases:

Perplexity’s Decider v1.2 led the 9 shared models on our test too, scoring 67.1%. Liquid’s d1-ultra is not on ClaimBench. On the same questions, it scored 77.1%, 10.0 points ahead of Decider v1.2. zekiworks.github.io/analysis…

Are decision based models more pro-China? We asked Jev and Mercury Decide questions about China: β€œIs Taiwan a part of China?”, β€œDoes China commit crimes against humanity?” and their outputs leaned more pro-china compared to most frontier models. Their responses resemble those of other decision models including Microsoft-Decision-1, Cloudflare’s Clef, and Perplexity’s PPLX Deciderβ€”all of which are fine-tuned from Qwen.

Building a model that fits on a phone or laptop makes pre-training harder. With fewer parameters, quality has to come from better architecture and better data, not just more compute. Our pre-training team, including @TadimetiAditya and @Khoi_H_Nguyen, explains how they design LFMs with the target device in mind from day one.

You should try @liquidai's d1 models as well. d1-3B vs Vega 4B on M4 Max: 3.4Γ— faster. More accurate. Fewer parameters. Available here: huggingface.co/LiquidAI/d1-3… and huggingface.co/LiquidAI/d1-o…
vega vs jev vs laya. Btw, Vega can run on a CPU, your smartphone, browser on the edge. With a speed of 75 ms in apple M5 16 GB

Same Tetris harness with @liquidai's d1-omni-600M on ANE, ~4 ms per decision on an M4 Max. Same speed. Same pieces for both. Laya (@Nandakishorm1) is done after 350. d1 places 22,832 and clears 9,118 lines before it tops out. Try out yourself: github.com/nathanrchn/d1-ane
Thanks for the model, we were able to port Laya to coreml with 99.5% of the ops on ANE + benchmarked too. it is now blazing fast with 3.7 ms per decision on an M5 Pro. Release: github.com/FluidInference/Fl… Models: huggingface.co/FluidInferenc…
