About

GPT-5.3-Codex is OpenAI’s most advanced agentic coding model, designed to handle complex professional work on a computer. It combines frontier-level coding performance with advanced reasoning and real-world task execution. The model is faster than previous Codex versions and can manage long-running tasks involving research, tools, and deployment. GPT-5.3-Codex supports real-time interaction, allowing users to steer progress without losing context. It excels at software engineering, web development, and terminal-based workflows. Beyond code generation, it assists with debugging, documentation, testing, and analysis. GPT-5.3-Codex acts as an interactive collaborator rather than a single-turn coding tool.

About

Grok Build 0.1 is a specialized AI coding model from xAI designed for agentic software engineering workflows and multi-step development tasks. The model is optimized to help coding agents perform actions such as planning, debugging, implementing changes, and iterating on code rather than simply generating one-time code responses. It supports both text and image inputs while producing text-based outputs, making it useful for analyzing code, screenshots, and technical documentation. Grok Build 0.1 includes support for tool use, structured outputs, function calling, and large-context reasoning capabilities. With a context window of up to 256,000 tokens, the model can process large codebases and complex projects within a single workflow. The platform is built for developers and engineering teams seeking faster and more capable AI-assisted software development.
