SenseNova‑MARS is a brand‑new open‑source vision‑language model (VLM) that lets developers build AI agents that can see, think, and act. Released by SenseTime on January 30 2026, the model comes in two sizes—8 B and 32 B parameters—and is built on a hybrid transformer‑Mamba architecture that keeps memory usage low while still delivering strong reasoning. In this article we’ll break down what SenseNova‑MARS is, how it works, why it matters, and how you can start using it today.
What is SenseNova‑MARS?
A vision‑language model is a type of AI that can understand both images and text. Think of it as a brain that can read a picture and then answer questions about it or write a caption. SenseNova‑MARS takes this a step further by adding agentic capabilities: the model can plan actions, enforce policies, and even trigger external events like sending an email or updating a database—provided the user gives it permission.
The “agentic” part means the model can reason about what to do next, rather than just produce a response. This is a big deal because most VLMs today are just “chatty” models that answer questions. SenseNova‑MARS can be the core of a fully autonomous system that interacts with the world.
Hybrid Transformer‑Mamba Architecture
SenseNova‑MARS uses a hybrid architecture that blends the classic transformer with a newer Mamba block. The transformer handles long‑range dependencies in text, while the Mamba block processes visual features more efficiently. This combination gives the model:
- Low memory footprint – the 8 B version fits on a single GPU with 24 GB of VRAM.
- Fast inference – the Mamba block reduces the number of operations needed for image processing.
- Scalable reasoning – the 32 B version can handle more complex tasks without a huge jump in latency.
Because the model compresses long context into parameters instead of storing tokens, it keeps latency constant even when the input is very long. That makes it ideal for applications that need to process large documents or long video frames.
Key Features of SenseNova‑MARS
| Feature | What It Means |
|---|---|
| Agentic Reasoning | The model can decide what action to take next, such as calling an API or updating a database. |
| Policy Enforcement | Built‑in policy checks let you restrict what the agent can do, preventing accidental data leaks. |
| Multimodal Input | Accepts text, images, and even short video clips in a single prompt. |
| Open‑Source | Anyone can download the weights, fine‑tune the model, or contribute to the codebase. |
| Cross‑Platform | Works on Linux, Windows, and macOS, and can be integrated with popular frameworks like PyTorch and TensorFlow. |
These features make SenseNova‑MARS a powerful tool for building AI agents that need to interact with the real world.
Use Cases
1. Enterprise Automation
Companies can use SenseNova‑MARS to build agents that read invoices, extract key data, and automatically update accounting systems. Because the model can enforce policies, you can set rules that prevent it from sending sensitive data outside the company network.
2. Research and Education
Researchers can fine‑tune SenseNova‑MARS on domain‑specific datasets, such as medical imaging or satellite photos, to create specialized agents that help with diagnostics or environmental monitoring.
3. Creative Content Generation
Content creators can feed the model a photo and ask it to write a story or generate a script. The agentic nature lets it suggest next scenes or even schedule publishing times.
4. Security and Compliance
Security teams can deploy SenseNova‑MARS to scan documents for policy violations. The model can flag images that contain restricted content and automatically trigger alerts.
How SenseNova‑MARS Compares to Other VLMs
| Model | Size | Architecture | Open‑Source | Agentic |
|---|---|---|---|---|
| SenseNova‑MARS | 8 B / 32 B | Transformer‑Mamba | Yes | Yes |
| Qwen3‑Max‑Thinking | 70 B | Transformer | No | No |
| DeepSeek MODEL1 | 7 B | Memory‑Efficient Transformer | Yes | No |
| Falcon‑H1R 7B | 7 B | Hybrid Transformer‑Mamba | Yes | No |
SenseNova‑MARS stands out because it is both open‑source and agentic. While Qwen3‑Max‑Thinking is powerful, it is not open‑source and lacks built‑in policy controls. DeepSeek and Falcon provide efficient architectures but are not designed for autonomous action.
Security and Policy Controls
SenseNova‑MARS is built with security in mind. The model can be wrapped in a policy engine that checks every action before it is executed. This is similar to the Virtue AI AgentSuite, which offers a multi‑layer security platform for enterprise AI agents. By combining SenseNova‑MARS with a policy layer, you can:
- Prevent unauthorized API calls – the agent can only call APIs that you whitelist.
- Log every action – keep a record of what the agent did for audit purposes.
- Enforce data residency – ensure that data never leaves a specified geographic region.
These controls make SenseNova‑MARS suitable for regulated industries like finance and healthcare.
Getting Started with SenseNova‑MARS
-
Download the Model
Visit the official GitHub repository and clone the repo. The weights are available under an Apache‑2.0 license. -
Set Up Your Environment
Install PyTorch 2.0 or TensorFlow 2.12, depending on your preference. The repo includes a Dockerfile for quick setup. -
Fine‑Tune on Your Data
Use the provided scripts to fine‑tune the 8 B or 32 B model on your own dataset. The training code supports distributed training across multiple GPUs. -
Wrap with a Policy Engine
Integrate the model with a policy engine like Virtue AI AgentSuite or build your own. The policy engine sits between the model and the external world. -
Deploy
Deploy the agent as a microservice behind an API gateway. You can also embed it in a desktop app or a mobile app using ONNX or TensorRT.

Future Outlook
The release of SenseNova‑MARS opens up many possibilities:
- Cross‑Modal Reasoning – combining text, image, and audio in a single agent.
- Long‑Term Memory – giving agents the ability to remember past interactions over weeks or months.
- Federated Learning – training the model on data that never leaves the user’s device.
SenseTime is already working on a 64 B version that will push the limits of reasoning further. Meanwhile, the open‑source community is experimenting with new training objectives and policy frameworks.
Conclusion
SenseNova‑MARS is a milestone in the world of AI. It brings together a powerful hybrid architecture, agentic reasoning, and open‑source accessibility. Whether you’re building an enterprise automation tool, a research prototype, or a creative assistant, SenseNova‑MARS gives you the flexibility to create agents that can see, think, and act responsibly.
