Qwen2.5-VL-32B: Reinforcement-Learning-Optimized Vision-Language Model Released
Alibaba's Qwen team has released Qwen2.5-VL-32B-Instruct, a 32-billion-parameter vision-language model built on the Qwen2.5-VL series and further optimized with reinforcement learning. The model is open-sourced under the Apache 2.0 license and available on Hugging Face and ModelScope. It follows the January 2025 launch of the broader Qwen2.5-VL series, positioning the 32B scale as a balance between capability and deployment practicality.
Qwen2.5-VL: Alibaba's New Flagship Vision-Language Model Released in 3B/7B/72B Sizes
Alibaba's Qwen team has released Qwen2.5-VL, their new flagship vision-language model, representing a significant upgrade over Qwen2-VL. The release includes both base and instruct variants in three sizes (3B, 7B, 72B), all open-weighted and available on Hugging Face and ModelScope. The 72B instruct model is also accessible via Qwen Chat. Key capabilities highlighted include enhanced visual understanding, with the model positioned as a major step forward in multimodal performance.
Qwen2.5-Coder Series Open-Sourced: 32B Model Claims SOTA, Matches GPT-4o on Coding
Alibaba's Qwen team has open-sourced the Qwen2.5-Coder family of code-specialized language models, with the flagship 32B-Instruct variant claiming state-of-the-art performance among open-source code models and parity with GPT-4o on coding benchmarks. The release spans multiple model sizes, expanding on previously released smaller variants. The models are described as combining strong coding ability with general reasoning and mathematical skills.
Qwen2.5-Coder Released: Next-Generation Open-Source Coding Model
Alibaba's Qwen team has released Qwen2.5-Coder, the next generation of their open-source coding-specialized language model, succeeding CodeQwen1.5 which launched in April 2024. The release also marks a rebranding from CodeQwen to Qwen-Coder. The model is available on GitHub, Hugging Face, and ModelScope.
Qwen2.5-Math: Open-Source Mathematical LLM Series Released
Alibaba's Qwen team has released Qwen2.5-Math, an upgraded series of open-source mathematical LLMs including base and instruction-tuned models at 1.5B, 7B, and 72B parameter scales, plus a mathematical reward model. The models support Chain-of-Thought (CoT) and Tool-Integrated Reasoning (TIR) for English and Chinese math problem solving. This follows the Qwen2-Math release approximately one month prior and is claimed to be the leading open-source mathematical LLM series.
Qwen2 Model Family Released: Five Sizes, 128K Context, Multilingual
Alibaba's Qwen team has released Qwen2, an evolution from Qwen1.5, comprising five pretrained and instruction-tuned models ranging from 0.5B to 72B parameters, including a 57B mixture-of-experts variant (57B-A14B). The release highlights training on 27 additional languages beyond English and Chinese, significantly improved coding and mathematics performance, and extended context support up to 128K tokens for the 7B and 72B instruct variants. Benchmark results are claimed to be state-of-the-art across a large number of evaluations.
Qwen1.5-MoE: Matching 7B Model Performance with 1/3 Activated Parameters
Alibaba's Qwen team releases Qwen1.5-MoE-A2.7B, a mixture-of-experts model with only 2.7 billion activated parameters that claims performance parity with 7B dense models such as Mistral 7B and Qwen1.5-7B. The model activates roughly one-third of its total parameters during inference, offering significant compute efficiency gains. This release follows growing industry interest in MoE architectures sparked by Mixtral, and the model is available on GitHub, HuggingFace, and ModelScope.
Introducing Qwen1.5: Open-Source Models Across Eight Sizes Including MoE
Alibaba's Qwen team released Qwen1.5, open-sourcing both base and chat models in eight sizes ranging from 0.5B to 110B parameters, plus a Mixture-of-Experts (MoE) variant. The release emphasizes developer experience improvements alongside model quality. Models are available on GitHub, Hugging Face, and ModelScope.
Qwen-VLA: Unified Vision-Language-Action Model Across Robot Tasks, Environments, and Embodiments
Alibaba's Qwen team presents Qwen-VLA, a unified embodied foundation model that extends the Qwen vision-language stack to continuous action and trajectory generation via a DiT-based action decoder. The model is jointly pretrained on diverse data spanning manipulation trajectories, egocentric demonstrations, synthetic simulation, and navigation data, with embodiment-aware prompt conditioning to support multiple robot platforms. A unified action-and-trajectory prediction framework covers manipulation, navigation, and trajectory prediction tasks. Benchmarks show strong results: 97.9% on LIBERO, 73.7% on Simpler-WidowX, 69.0% OSR on R2R navigation, and 76.9% average OOD success in real-world ALOHA experiments.
Qwen-Image-Edit: Image Editing Model with Text Rendering and Dual Visual Control
Alibaba's Qwen team has released Qwen-Image-Edit, a 20B-parameter image editing model built on the Qwen-Image foundation. The model extends Qwen-Image's text rendering capabilities to editing tasks, enabling precise in-image text modification. It uses a dual-path architecture that simultaneously feeds input images into Qwen2.5-VL for semantic control and a VAE Encoder for appearance control, enabling both semantic and appearance-level edits.
QwQ-Max-Preview Released by Qwen Team
Alibaba's Qwen team has released QwQ-Max-Preview, a preview version of their reasoning-focused model built on top of Qwen2.5-Max. The post is itself generated by the model, serving as a demonstration of its capabilities. As a preview release, it signals an upcoming full model launch in the Qwen series.
Chinese CLIP: Contrastive Vision-Language Pretraining in Chinese
Alibaba's Qwen team released Chinese CLIP, a language-specific vision-language contrastive pretraining model targeting Chinese multimodal representation learning. The project addresses a gap in open-source Chinese CLIP models, particularly for cross-modal retrieval tasks. It follows the CLIP framework but is adapted for Chinese language and cultural context.
RELEX: Extrapolating LLM RLVR Training via Rank-1 Parameter Trajectories
This paper demonstrates that RLVR weight update trajectories are extremely low-rank and near-linearly predictable, with a rank-1 approximation capturing most downstream performance gains. The authors propose RELEX, a compute-efficient method that observes a short training window, estimates the rank-1 subspace, and extrapolates future checkpoints via linear regression—requiring no additional training. Evaluated on Qwen2.5-Math-1.5B, Qwen3-4B-Base, and Qwen3-8B-Base, RELEX matches or exceeds full RLVR performance using as few as 15% of training steps, and can extrapolate up to 10–20× beyond the observed prefix. The authors attribute the method's effectiveness to a denoising effect from rank-1 projection that discards stochastic optimization noise.
