English performance doesn't necessarily translate to other languages. Multiple languages can be toggled to rank models on multilingual performance. Seed TTS Eval only has movie box audio for English and Chinese, so the other languages are simply the score on CV3 Eval (zero shot). Note that Chinese, Japanese, and Korean are character-based languages and so character error rate (CER) is reported, and the “Average WER” across languages is a macro-average across languages.
Open TTS Leaderboard is an open evaluation platform designed to make multilingual text-to-speech and voice-cloning models easier to compare at scale. Traditional TTS arenas usually let users listen to outputs from two models and choose the one they prefer. Those votes can then be used to calculate an Elo-style score, often through approaches such as the Bradley–Terry model, giving users a simple way to understand how different systems perform based on human preference.
Human feedback remains an important part of evaluating speech quality, but relying only on arena-style voting can be difficult as new TTS models are released at a rapid pace. Open-source models can also face practical barriers because they generally need to be hosted and served by the evaluation platform, while API-based commercial models can be added more easily. This can result in open-weight systems being less visible on public leaderboards. Another challenge is consistency: people's preferences and listening criteria can change over time, meaning that votes collected months apart may not always represent exactly the same standards.
Open TTS Leaderboard aims to address these challenges by providing a scalable and transparent space for evaluating multilingual TTS and voice-cloning systems. The goal is to make comparisons easier to reproduce, expand coverage of open models, and provide useful evaluation signals alongside human preference. By bringing together scalable testing and community feedback, the project can help researchers, developers, and users better understand how speech models perform across different languages, voices, and use cases.
The vision drafter uses the same architecture as our text LFM2.5-DSpark drafters: it captures the target model's hidden states at a fixed set of tapped layers and conditions on them to moviesda draft a block of k candidate tokens. Image patches and text tokens are projected into a shared representation before those layers, so the drafter operates on hidden-state vectors of identical dimensionality regardless of input modality. The inference algorithm is therefore unchanged from the text models.
This is a really interesting step toward making vision-language models faster and more practical in real-world applications. The reported speedups of up to 3.13x on-device and 2.66x on an H100 are especially notable because the approach aims to improve inference speed without changing the output quality, while keeping the additional memory requirement relatively small.
I also like how the DSpark approach carries the same core idea from text models into the vision-language setting. Having the image patches and text tokens projected into a shared representation means the drafter can work with the same hidden-state dimensions across both modalities, which makes the speculative decoding process much more straightforward and reusable.
The day-one support for llama.cpp, MLX-VLM, and SGLang also makes this especially interesting for developers experimenting with local and accelerated VLM inference. It will be worth watching how these gains translate across different hardware and workloads as the experimental model develops.
LoRA training is particularly suited for RL, as shown in Thinking Machines's blog LoRA Without Regret. They show that LoRA can match full fine-tuning for policy-gradient RL, even with sportzfy rank 1. This stems from the fact that the advantage function only gives ~O(1) bits of information per episode, so there is not that much to learn from each step, from a total-bits-of-information point of view. A rank-1 adapter has enough capacity to absorb it.
Really interesting take on how LoRA changes the systems side of RL training, not just the training itself. The idea of separating training and inference across different machines while only moving a small adapter instead of the full model makes a lot of practical sense, especially when working with HF Jobs. The “bucket, proxy, and no NCCL” approach feels like a good example of simplifying distributed infrastructure by moving the communication boundary to something much smaller and easier to manage.
I also like the connection to the LoRA Without Regret work, particularly the point that policy-gradient updates may not require huge adapter capacity to capture the useful signal. Sending only a few MB instead of several GB after updates can make a massive difference in both bandwidth and iteration speed. Would be really interested to see more details on how the bucket/proxy setup behaves at scale and whether there are any noticeable trade-offs once the number of inference workers or concurrent rollouts increases.
Making a large language model smaller almost always comes with a cost. The now-standard recipe for efficient deployment is to compress the architecture first, cutting the parameter count by removing layers, heads, or neurons, and then quantize the remaining weights down to 4 bits to shrink memory and compute further. Both steps save a lot, but together they systematically degrade the capabilities people actually care about: reasoning, mathematical problem-solving, and code generation. Because of this, serious deployment pipelines add a recovery step, usually called healing, before the model goes into production. Recent open-weight releases such as rbtv77 gpt-oss, NVIDIA's Nemotron family, and our own Hypernova 60B all rely on some version of this compress-then-heal approach.
This is a really fascinating take on model compression 🤯🔥. The idea that a 4-bit model can actually outperform the full-precision version turns the usual assumption about quantization completely upside down.... Instead of simply accepting the accuracy loss that comes with compression, QAH seems to show how targeted recovery can bring back—and even improve—important capabilities like reasoning, math, and coding. 🧠⚡
What really caught my attention is the result with the compressed GPT-OSS 120B → 60B model.... Getting a smaller MXFP4 model to beat its own bfloat16 checkpoint on 7 of 9 benchmarks is pretty impressive. 📊🚀 It makes the whole compress-then-heal pipeline feel much more practical for real-world deployment, especially when memory usage and inference costs matter.
I also like the broader implication here.... Quantization doesn't necessarily have to mean sacrificing model quality if the recovery process is designed with the quantized model in mind. 💡🔧 A smaller model that costs less to operate while still delivering stronger benchmark performance could be a huge advantage for teams trying to deploy capable LLMs efficiently.
Definitely an interesting direction for efficient AI deployment.... Turning a heavily compressed 4-bit model into something that can outperform its larger full-precision counterpart is the kind of result that makes you rethink what "compression" actually means. 👏🔥 Really curious to see how far Quantization-Aware Healing can go across other architectures and workloads.... 🚀🧠
Assessing more than just visual quality is the immediate next step. A practical surgical simulator must enable findings that translate to the real robot, maintain instrument and scene organization during extended rollouts, and react appropriately to actions. Tool-tip reach and pose accuracy, gripper-cycle fidelity, idle stability, counterfactual action variety, long-horizon drift, and agreement between simulated and actual policy outcomes are some of the new closed-loop benchmarks that are motivated by this.
The progress in surgical robotics is genuinely exciting! 🏥🤖 Being able to train and test advanced vision-language-action systems in realistic simulations without risking expensive equipment or delicate procedures could make development much faster and safer. The level of detail needed for tissues, instruments, smoke, and lighting really shows how challenging this field is. 👏
It’s impressive to see technology moving beyond simple teleoperation and towards smarter, more capable robotic assistance. 🚀 Better simulation environments can help researchers refine these systems before they ever reach an operating room, which is a win for both surgeons and patients. 😊📱
Looking forward to seeing how projects like NVIDIA Cosmos-H-Dreams shape the future of healthcare. 🌍💙 If these simulations continue becoming more realistic, they could play a huge role in improving surgical training, reducing costs, and ultimately delivering better patient outcomes. Amazing work and an exciting glimpse into what's ahead! 🙌✨
