Meituan releases LongCat-2.5, a multimodal model with 1.6 trillion parameters for coding long-horizon agents

The LongCat team at Meituan introduced the LongCat-2.5 model on November 2nd. This model is a native multimodal system designed to perform long-horizon agent tasks. According to IT Home, the model has a total of 1.6 trillion parameters and activates about 48 billion of them when processing each token.

LongCat-2.5 is based on the previous LongCat-2.0 version and significantly improves two key aspects: native visual data understanding and agent coding capability. The official release followed a preliminary version, LongCat-2.5-Preview, which was available on the LongCat API platform since September 25th.

Improvements in Training and Task Handling

A large part of the training process focused on long-term tasks. Meituan reported adding more long-horizon trajectory data to long sequence training and utilizing large-scale long-horizon reinforcement learning to refine end-to-end engineering work. This includes developing within complex codebases and creating complete projects.

The team continues to expand data synthesis, build environments, and conduct mixed training across various agent mechanisms. Furthermore, they convert failure trajectories of real agents into reproducible and verifiable tasks for training, allowing them to continuously replenish the database in areas where the model shows weaknesses.

Visual Understanding and Infrastructure

In terms of image processing, LongCat-2.5 represents visual signals as multi-level discrete tokens. This allows the core of the model to process images and text in a unified tokenized format. Meituan asserts that combining this native vision with agent coding makes the model strong in visual coding, enabling it to handle creative design and 3D tasks.

The infrastructure supporting the model's release operates on domestic computing power. Meituan optimized long-context training and W4A4 inference, which uses 4-bit weights and 4-bit activations, on internal chips. Work on numerical consistency between training and inference, along with optimizing long-context deployment, ensures the efficient operation of large-scale long-horizon reinforcement learning.

Testing Results and Availability

According to the benchmark table presented by Meituan itself, LongCat-2.5 achieved a score of 88.4 on Terminal Bench v2.1, surpassing LongCat-2.0's 70.8, and 51.8 on AutomationBench compared to 15.8. The model also reached 91.9 on BrowseComp, 82.1 on PaperBench, 55.4 on 3DCodeBench, and 78.6 on Vision2Web. When compared to state-of-the-art models from other labs, LongCat-2.5 does not hold the top spot in all tests; for instance, it scores 25.5 on Program Bench versus 37 by the best competitor. It should be noted that these metrics have not yet undergone independent verification.

The LongCat changelog indicates that the model is compatible with Claude Code, Codex, Hermes, and other major frameworks, and the platform documentation contains guides for configuring tools such as OpenCode, Cline, Kilo Code, CodeBuddy, and WorkBuddy. LongCat-2.5 is available at longcat.chat and via the LongCat API, with Meituan announcing upcoming releases on GitHub and Hugging Face.

Dawa Technology's Scenes AI works with 34-billion parameter world models in real-time on a single RTX GPU

Dawa Technology, a company based in Chongqing that originated from the field of virtual film production, has introduced Scenes AI—a real-time world model. This system is capable of transforming video shot with a regular camera into an editable and persistent world.

The product received an excellence award at NVIDIA's intermediate startup event in Suzhou on October 15. Thirty members of NVIDIA Inception participated in this stage among more than 580 attendees.

Most video models focus on predicting the next frame. However, Scenes AI supports a continuous world state. Elements such as the scene, people, camera, lighting, objects, and physics are stored as separate variables that can be read and modified independently. When a change occurs, only the corresponding part of the state is updated, not the entire image redrawn.

In demonstrations, Dawa showed how a room transforms into a hand-drawn meadow while the chair, teddy bear, and wardrobe maintain their positions. Wall inscriptions remain in place, and people appear and disappear, while the weather changes from snow to rain.

The system includes a complex control layer and a lightweight generative layer. The control layer, built around the Latent Stage module, separates the scene, character, camera, lighting, costume, and props in latent space, applying physical constraints for solids, fabrics, liquids, and particles. The rendering layer, LiveStage, uses causal sparse diffusion to sample only the changing areas.

The model has a total of 34 billion parameters but activates about 4 billion per step, which is approximately 11.8 percent. Dawa claims this reduces GPU usage by 40–60 percent and accelerates inference three to five times compared to traditional video diffusion.

On a single consumer NVIDIA GeForce RTX card, the system achieves real-time output at 720p resolution and 25 frames per second. In continuous editing tests, the company reports a 98.2 percent success rate for target editing and a 93.3 percent preservation of human identity. The system utilizes CUDA, TensorRT, and NVENC and operates on local hardware without cloud computing.

Dawa states that its data was gathered from an 84,000 square meter studio space, over 300 real productions, and 180 TB of world state data. The company's Chief Product Officer, Li Zongxin, summarized the approach as follows: 'Video can end, but the world must keep running.' All presented performance metrics are data provided by the company itself.

DeepSeek and MiniMax Complete AI Export Registration and Begin International Licensing

Two prominent Chinese artificial intelligence model developers, DeepSeek and MiniMax, have successfully completed the registration process introduced as part of the proposed update to the country's export technology catalog. Both companies have continued their operations by releasing open-source models and initiating international licensing.

This information was revealed on the evening of October 22nd via the Yuyuan Tantian account belonging to the state broadcaster China Media Group. These developments occur against the backdrop of a project to revise the Catalog of Prohibited or Restricted Export Technologies, which the Ministry of Commerce and the Ministry of Science and Technology put out for public comment on October 16th.

The draft changes included 23 items related to AI, covering large models, AI agents, computing clusters, and information processing. The catalog itself has already drawn attention, and this new information confirms that two leading model developers have already applied this process in practice.

It is important to note that registration differs from obtaining a restrictive license, and this catalog is currently a consultative draft, not a final list. According to the Ministry of Commerce, technologies that have already become publicly available through open-source releases or academic publications are proposed to be excluded from export regulation.

Automatic licensing is provided for cases where Chinese companies build and operate overseas data centers, as well as for joint research utilizing foreign resources; the ministry describes this process as being close to export after an application is submitted.

The Ministry has also defined the boundaries of how models reach users abroad. Providing a restricted model via API calls, applications, or web interfaces, as well as in the form of SaaS products or light local deployment on a device, is not considered the export of large model technology. However, local deployment of a restricted model abroad falls under export control, although placement on the company's own overseas cloud infrastructure may utilize automatic licensing.

The Ministry emphasized that the vast majority of AI technologies will remain freely exportable.

The practical steps taken by the companies are giving concrete shape to the process. As reported by Huxiu, DeepSeek opened its framework for large-scale inference, DeepInfer, and the accompanying deepseek-recipe toolkit on October 20th. MiniMax, meanwhile, set up an official application pathway for foreign regions previously excluded from its model licenses, including the United States, the European Union, the United Kingdom, and South Korea.

Under this approach, model weights remain open, but organizations in these regions must undergo compliance checks and obtain a license before deploying the models locally. For developers, this means that open weights, open source code, and API access will likely remain as they are, while local deployment of the most sensitive technologies abroad will require an application procedure. The discussion period for the catalog draft is still ongoing, and the final scope of regulation may change before it comes into effect.

VAST releases open-source model EdenLive for rendering simple game frames into detailed video

VAST, a company specializing in generative AI in 3D and behind the Tripo platform, has made the EdenLive model publicly available. This model operates in real-time and is capable of taking simplified game frames or existing video, continuously re-rendering them into detailed images in a chosen style, which can range from photorealistic to anime.

The release includes 5B and 14B model weights, code for real-time inference, a technical report, and end-to-end usage demonstrations. It is important to note that EdenLive does not simulate the world on its own; instead, a higher-level program, such as a game engine or code written by a coding agent, is responsible for enforcing rules, tracking world state, and outputting a rough reference video.

After receiving this reference video, EdenLive performs the rendering, guided by the initial frame and a text prompt. VAST asserts that this separation allows game logic to remain explicit and testable, while concentrating the model's limited real-time capabilities solely on the visual appearance.

The approach was first presented in June as part of a larger world research effort known as Project Eden. According to VAST, the 5B model can operate at a frame rate above 24 frames per second at 720p resolution on a single Nvidia RTX 5090 GPU. The README file on GitHub specifies this figure as approximately 24.7 FPS at a resolution of 1280 by 704 pixels, utilizing acceleration from the LightX2V inference framework.

The technical report reports a rate of 29.8 FPS at the same resolution on a single H100, as well as 26.8 FPS at a resolution of 832 by 480 for the 14B model running on eight H100s. VAST states that the total latency from user input to the corresponding frame is in the hundreds of milliseconds, and the system can generate content continuously for several minutes.

Both models are based on the Wan2.2-TI2V-5B and Wan2.1-I2V-14B video models. The inference code and core diffusion, VAE, and decoder weights are distributed under the Apache 2.0 license, although not all components have this license. The visual encoder uses the DINOv3 license, and the image model used in the request-to-game workspace is under the Non-Commercial FLUX License, which restricts the use of this workspace to non-commercial purposes.

VAST also introduced Game Prototype Turbo—a skill that transforms a text prompt into a rough playable game, which EdenLive can then render. VAST demonstrations include a platformer where a character freezes lava to create waypoints, a two-player fighting game where health bars and round timers are tracked by a higher-level system, and video rendering that transforms a person filmed against a blue background into a cartoon character. Furthermore, the model demonstrates replacing human hands with robotic ones in first-person footage to create additional training data for embodied AI.

VAST notes that EdenLive is currently best suited for low-frequency interactions, such as scene inspection and box-pushing puzzles. Fast, intense gameplay, maintaining multi-character consistency, fine control over small objects, and visual stability during long sessions still require refinement.
