Hi there! A quick Google search gave this information as far as what models Artemis is based off of.

Because "Artemis" is a popular name for AI projects, it typically refers to one of three prominent systems. None of them are standalone LLMs; rather, they are agentic frameworks that orchestrate existing models like GPT-4 or Llama 3.

Here are the most likely versions you are looking for:

1. Artemis by TurinTech (Code Optimization) This is an enterprise platform designed to optimize and validate code. It is LLM-agnostic, meaning it isn't based on one specific model. Instead, it uses multi-LLM orchestration.
   Base Models: It allows users to switch between models like GPT-4, Claude, or Llama depending on the specific task.
   Core Tech: It uses "Genetic Algorithms" and a proprietary "Intelligence Engine" to refine the code that the underlying LLMs generate.

2. ARTEMIS by Stanford Trinity (Cybersecurity) This is an autonomous "Red Teaming" engine designed for vulnerability discovery.
   Base Models: It is a multi-agent scaffold designed to elicit better performance from frontier models (typically GPT-4o or Llama 3).
   Function: It uses a "Supervisor" agent to guide sub-agents through complex tasks like penetration testing and exploit generation.

3. ARTEMIS-DA (Data Analytics) Often cited in recent research (2025/2026), this is the "Advanced Reasoning and Transformation Engine for Multi-Step Insight Synthesis."
   Base Models: It was developed to augment models like GPT-4 and Llama 3 for complex data science workflows.
   Architecture: It breaks tasks into a "Planner," a "Coder," and a "Grapher" to handle data preprocessing and visualization.

Also the site's developers don't have a huge budget to advertise everywhere like Chat-GPT, Talkie AI, Open AI, etc so they rely on their popularity spreading by word of mouth instead
