5 Essential AI Architectures Every Engineer Should Be Familiar With

Understanding the AI Ecosystem

If you’re diving into artificial intelligence, there’s so much more to it than just Large Language Models (LLMs). In fact, the AI market is filled with various specialized architectures that enhance how machines perceive, plan, and execute. Here, we’ll discuss five key AI architectures: LLMs, Vision-Language Models (VLMs), Mixture of Experts (MoE), Large Action Models (LAMs), and Small Language Models (SLMs).

1. Large Language Models (LLMs)

LLMs have gained immense popularity for good reason. They process text in a systematic way: breaking it down into tokens, converting those tokens into embeddings, passing them through transformer layers, and generating text as output. Models such as ChatGPT, Claude, and Gemini are prime examples of this architecture.

At their core, LLMs are deep learning models trained on vast amounts of textual data, enabling them to understand language and perform numerous tasks—ranging from summarization to coding. These models take advantage of the transformer architecture, which excels in handling extensive sequences and identifying complex language patterns.

You can easily access these models through a variety of consumer tools, such as OpenAI’s ChatGPT, Anthropic’s Claude, and Google’s Gemini. Their capability and user-friendly nature make them foundational elements of modern AI applications.

2. Vision-Language Models (VLMs)

VLMs are where two domains collide: visual and textual processing. These models feature a vision encoder for images or videos and a text encoder for language, all converging in a multimodal processor to produce outputs.

For instance, models like GPT-4V and LLaVA exemplify this architecture. VLMs expand the capabilities of traditional computer vision models, which typically handle single tasks, such as identifying objects. Unlike their one-dimensional counterparts, VLMs can understand and interpret a wide array of visual tasks using natural language instructions.

This flexibility allows VLMs to perform a multitude of tasks—image captioning, optical character recognition (OCR), and visual reasoning—without the necessity for task-specific retraining. This makes them a potent addition to the AI toolkit. You might also enjoy our guide on Wall Street Strategist Exits Bitcoin: A Deep Dive.

3. Mixture of Experts (MoE)

MoE models enhance the standard transformer framework by introducing multiple smaller networks instead of relying on a single feed-forward network for every layer. This intelligent design allows the model to activate only a subset of its expert networks for each token, significantly enhancing efficiency while maintaining high capacity. (CoinDesk)

The typical transformer architecture requires that all tokens go through the same feed-forward network, which uses all parameters for every token. MoE models flip this paradigm, selecting only the necessary experts for processing, thus optimizing performance without compromising on capacity.

For instance, the Mixtral 8×7B features over 46 billion parameters but only uses around 13 billion for each token. This setup allows for reduced inference costs, making MoE models an efficient choice as they scale by adding more expert networks rather than making the model deeper.

4. Large Action Models (LAMs)

Going beyond simple text generation, LAMs are designed to turn a user’s intent into actionable steps. They don’t just answer questions; they understand what the user aims to achieve and can plan and execute tasks accordingly.

A LAM typically includes several steps:

• Perception: Grasping the user’s input.
• Intent Recognition: Identifying the user’s objectives.
• Task Decomposition: Breaking the goal into manageable steps.
• Action Planning & Memory: Determining the sequence of actions based on context.
• Execution: Carrying out tasks autonomously.

Examples of LAMs include Rabbit R1 and Microsoft’s UFO framework, which can execute applications, navigate interfaces, or complete various tasks for users. This transformative capability elevates AI from being a passive assistant to an active collaborator.

5. Small Language Models (SLMs)

Designed for efficiency, SLMs are lightweight language models that operate within resource-constrained environments like mobile devices or IoT systems. They take advantage of optimized tokenization and transformer layers to ensure smooth on-device deployment.

While traditional LLMs can have billions of parameters, SLMs typically range from a few million to a few billion. Despite their smaller size, they’re still capable of understanding and generating natural language. This makes them perfect for various tasks like chat, summarization, and translation without relying on cloud computing.

Due to their low memory and processing requirements, SLMs shine in: (Bitcoin.org)

• Mobile applications
• IoT devices
• Privacy-sensitive scenarios
• Applications requiring low latency

With the rise of SLMs, there’s a noticeable shift towards AI that prioritizes speed, privacy, and efficiency, bringing advanced language capabilities closer to users.

Conclusion

Understanding these five AI architectures can help engineers and developers navigate the complex world of artificial intelligence. Each of these models plays a unique role in shaping the future of AI, offering specialized solutions for various applications.
