The Joint Large Model based on LLM (Large Language Model), SLM (Small Language Model), and TinyML (Tiny Machine Learning) is essentially a comprehensive model architecture that intelligently selects the appropriate model for inference and computation according to task requirements and device resources. Such a large model aims to optimize resource usage, improve processing efficiency, and handle tasks of varying complexity.

1. Multi-level, Distributed Inference

One of the design principles of the Joint Large Model is multi-level and distributed inference. Different models execute on different devices and computational resources:

LLM: Runs on cloud or high-performance servers for tasks requiring substantial computational resources, such as complex text generation, long-form question-answering systems, etc.

SLM: Runs on mobile or edge devices, suitable for real-time tasks with relatively low computational demands, such as simple question-answering, sentiment analysis, keyword extraction, etc.

TinyML: Runs on extremely low-power devices (like sensors, microcontrollers, etc.), handling simple, application-specific machine learning tasks such as voice recognition, action recognition, environmental monitoring, etc.

Joint Architecture Example:

When a device detects the need for complex semantic processing (e.g., generating long articles or deep dialogues), the model can forward the request to the cloud-based LLM.

For everyday simple queries and inferences, SLM can execute directly on the phone or local device, reducing latency and saving bandwidth.

In the most resource-constrained situations (like microcontrollers or sensors), TinyML can handle specific tasks, such as classifying sensor data or behavior recognition.

2. Intelligent Selection and Task Allocation

The Joint Large Model needs to possess the capability for intelligent task scheduling and selection, dynamically selecting the appropriate model based on device resources, task requirements, and network conditions:

Task evaluation and allocation: The model automatically determines whether to invoke LLM, SLM, or TinyML based on the complexity and requirements of the input task. For example, a simple text classification task can be accomplished by SLM on the phone, while a more complex multi-turn dialogue would require LLM to be executed in the cloud.

Resource optimization: If the network connection is unstable, the system can automatically offload more computational tasks to edge devices (SLM or TinyML), minimizing reliance on cloud processing. Conversely, when network conditions are good, heavier computational tasks may be assigned to LLM.

3. Leveraging the Strengths of Different Models

The Joint Model can also achieve more efficient inference by merging the strengths of LLM, SLM, and TinyML.

LLM provides powerful language understanding and generation capabilities, especially suitable for complex natural language processing tasks, such as generative dialogue, content creation, long-form translation, etc.

SLM offers quick response and lower latency processing capabilities, suitable for executing lighter tasks on mobile or edge devices, capable of handling simple inference tasks such as sentiment analysis, brief dialogues, text summarization, etc.

TinyML enables low-power, real-time edge inference, ideal for real-time applications and low-power devices, such as environmental monitoring, health monitoring, action recognition, etc.

By combining these models, the Joint Model can provide more comprehensive and efficient processing capabilities while ensuring that different tasks run efficiently on suitable hardware.

4. Cross-platform and Cross-device Collaboration

The Joint Large Model architecture emphasizes cross-platform collaboration, meaning it can seamlessly operate across different hardware platforms and computing environments.

Cloud (LLM): Handles tasks requiring high computational power and large-scale data.

Edge devices (SLM): Handle tasks suitable for local fast inference and collaborate with the cloud under certain conditions.

Micro devices (TinyML): Handle low-power, efficient real-time tasks, suitable for large-scale distributed applications, such as IoT devices.

This collaborative model allows each model to leverage its strengths, avoiding overly complex models running on resource-constrained devices, thus ensuring the efficiency and responsiveness of the entire system.

5. Application Scenarios for Joint Large Models

Joint Large Models have immense potential across various application scenarios, especially in contexts requiring the handling of tasks with varying complexities.

Smart homes and the Internet of Things (IoT): In smart home systems, TinyML can process basic sensor data and action recognition, while complex voice assistant functions (like long text generation, deep dialogues) can be handled by cloud-based LLM.

Health monitoring: In smart health devices, TinyML can be used for real-time monitoring of heart rates, steps, and other physiological data, while SLM and LLM can collaborate as needed for more complex diagnostic tasks, providing deeper analysis.

Smart vehicle systems: In-car devices can use TinyML to monitor the driver’s physiological state and driving behavior in real time, SLM for processing voice commands, and LLM for complex interactions and navigation requests between the vehicle and driver.

6. Challenges and Future Development

While Joint Large Models have many advantages, they also face challenges, particularly in areas like model coordination, computational resource allocation, real-time performance, and cross-platform compatibility.

More efficient task scheduling algorithms: Can more intelligently select suitable models based on resources and task requirements.

Model compression and optimization: Through techniques like pruning and quantization to make LLM, SLM, and TinyML models more efficient and adaptable to various hardware platforms.
