New model additions

Qwen3 Next

The Qwen3-Next series represents the Qwen team's next-generation foundation models, optimized for extreme context length and large-scale parameter efficiency. The series introduces a suite of architectural innovations designed to maximize performance while minimizing computational cost:

• Hybrid Attention: Replaces standard attention with the combination of Gated DeltaNet and Gated Attention, enabling efficient context modeling.
• High-Sparsity MoE: Achieves an extreme low activation ratio as 1:50 in MoE layers — drastically reducing FLOPs per token while preserving model capacity.
• Multi-Token Prediction(MTP): Boosts pretraining model performance, and accelerates inference.
• Other Optimizations: Includes techniques such as zero-centered and weight-decayed layernorm, Gated Attention, and other stabilizing enhancements for robust training.

Built on this architecture, they trained and open-sourced Qwen3-Next-80B-A3B — 80B total parameters, only 3B active — achieving extreme sparsity and efficiency.

Despite its ultra-efficiency, it outperforms Qwen3-32B on downstream tasks — while requiring less than 1/10 of the training cost. Moreover, it delivers over 10x higher inference throughput than Qwen3-32B when handling contexts longer than 32K tokens.

Vault Gemma

VaultGemma is a text-only decoder model derived from Gemma 2, notably it drops the norms after the Attention and MLP blocks, and uses full attention for all layers instead of alternating between full attention and local sliding attention. VaultGemma is available as a pretrained model with 1B parameters that uses a 1024 token sequence length.

VaultGemma was trained from scratch with sequence-level differential privacy (DP). Its training data includes the same mixture as the Gemma 2 models, consisting of a number of documents of varying lengths. Additionally, it is trained using DP stochastic gradient descent (DP-SGD) and provides a (ε ≤ 2.0, δ ≤ 1.1e-10)-sequence-level DP guarantee, where a sequence consists of 1024 consecutive tokens extracted from heterogeneous data sources. Specifically, the privacy unit of the guarantee is for the sequences after sampling and packing of the mixture.

Qwen3 VL

Qwen3-VL is a multimodal vision-language model series, encompassing both dense and MoE variants, as well as Instruct and Thinking versions.

Building upon its predecessors, Qwen3-VL delivers significant improvements in visual understanding while maintaining strong pure text capabilities. Key architectural advancements include: enhanced MRope with interleaved layout for better spatial-temporal modeling, DeepStack integration to effectively leverage multi-level features from the Vision Transformer (ViT), and improved video understanding through text-based time alignment—evolving from T-RoPE to text timestamp alignment for more precise temporal grounding.

These innovations collectively enable Qwen3-VL to achieve superior performance in complex multimodal tasks.

Longcat Flash

The LongCatFlash model was proposed in LongCat-Flash Technical Report by the Meituan LongCat Team. LongCat-Flash is a 560B parameter Mixture-of-Experts (MoE) model that activates 18.6B-31.3B parameters dynamically (average ~27B). The model features a shortcut-connected architecture enabling high inference speed (>100 tokens/second) and advanced reasoning capabilities.
