Introduction to the Models

The current AI landscape is witnessing a shift toward models that not only process language but can also autonomously perform complex real-world tasks. Let’s introduce the three models in question:

DeepSeek-R1

DeepSeek-R1 is a high-performance Chinese AI model designed for advanced reasoning, coding, and STEM problem-solving. It leverages a unique Mixture of Experts architecture that consists of a massive 671 billion total parameters—of which only 37 billion are active per query. This design allows DeepSeek-R1 to deliver exceptionally precise and detailed responses, particularly for complex tasks. However, its strength comes at a cost: it requires high-end GPUs to run efficiently.

Gemma 3

Developed by Google, Gemma 3 is a lightweight, open-source, multimodal language model available in various sizes (1B, 4B, 12B, and 27B parameters). Despite its smaller parameter count, Gemma 3 is optimized for efficiency and is designed to run on a single GPU or TPU. It can process text, images, short videos, and even audio files, thanks to its multimodal capabilities. With an extended context window (up to 128K tokens), Gemma 3 strikes an impressive balance between performance and computational resource demands while seamlessly integrating into Google’s ecosystem. Gemma API is also becoming helpful for businesses to leverage the platform to enhance their business workflow.

Manus AI

Manus AI is an autonomous AI agent developed by the Chinese startup Monica and officially launched on March 6, 2025. Unlike the more traditional language models, Manus AI is built to work independently. It can take broad user instructions and transform them into fully executed workflows, handling tasks such as writing code, generating reports, planning trips, and even deploying web applications. Using a multi-agent system, Manus AI decomposes complex tasks into subtasks and assigns them to specialized agents that work collaboratively, thereby pushing the boundaries of what autonomous AI agents can do.

Performance Comparison

Task 1: Coding

In the coding test, each model was tasked with writing a Python program to create a physics-based animation of a ball bouncing inside a spinning pentagon.

Manus AI: Aimed to execute a full autonomous workflow, generating comprehensive code with deployment instructions. While its output included end-to-end guidance, early tests showed occasional glitches or delays.

Task 2: Logical Reasoning

The logical reasoning test involved solving a classic puzzle: “A solid, four-inch cube of wood is painted on all sides and then cut into one-inch cubes. How many small cubes will have three, two, one, or no painted sides?”

DeepSeek-R1: Delivered a detailed, step-by-step explanation that provided transparency in its reasoning process, though it took nearly twice as long as Gemma 3.

Gemma 3: Solved the puzzle in approximately 30 seconds, providing a concise and correct answer by integrating its thought process directly into the response.

Manus AI: Utilized its multi-agent system to break down the problem and deliver the correct answer. However, it occasionally encountered context issues with very straightforward tasks.

Task 3: STEM Problem-Solving

For the STEM challenge, the task was to calculate the orbital velocity and the period of revolution for a 500 kg satellite orbiting Earth at an altitude of 500 km.

DeepSeek-R1: Provided a meticulous explanation with proper SI units and detailed mathematical derivation, leading to highly accurate and reliable answers.

Gemma 3: Delivered a quick response with clear step-by-step breakdowns, though a minor miscalculation in the value of 2πr led to a small error in the orbital period.

Manus AI: Generated a comprehensive solution that included a detailed breakdown of both calculations. While occasionally experiencing delays or context overflow, its overall approach demonstrated its potential for handling multi-step STEM tasks autonomously.
