GPT-5 Codex is the latest iteration of OpenAI's language model specialized in Code Generation, Gpt 4.1 offering enhanced reasoning, faster response times, and improved coding capabilities compared to GPT-4. O4 (OpenAI Omni Model), also known as GPT-4o, is a multimodal model that can process text, images, delivering real-time interaction with powerful intelligence and natural communication.

Developed by Anthropic, Claude 4 Sonnet is known for its deep contextual understanding, safety, and aligned responses. It’s great for tasks requiring critical thinking, document analysis, and conversation with a human-like tone.

Grok Fast Code is the code-generation model developed by xAI, Elon Musk's AI company. Integrated into X (formerly Twitter), it emphasizes real-time knowledge and reasoning with access to up-to-date information, making it ideal for dynamic, current-events-driven tasks.

Qwen 3 Coder is a large open‑source AI model from Alibaba Cloud, purpose‑built for programming tasks such as code generation, debugging, and multi‑step reasoning. It uses a Mixture of Experts (MoE) design with over 400 billion total parameters but activates only about 35 billion at a time, giving it the efficiency of a smaller model with the power of a much larger one.
