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
MiMo Code is a terminal-native AI coding assistant designed to live inside the developer’s computer, understand the project more deeply over time, and improve as it works. It can read and write code, run commands, manage Git, and keep a persistent project context across sessions through a built-in memory system. Instead of relying on the model to remember on its own, MiMo Code uses project memory, conversation checkpoints, scratch notes, task progress, and SQLite FTS5 full-text search to preserve rules, architecture decisions, session state, and ongoing work. When context nears the limit, it reconstructs the working state from the latest checkpoint, memory, task progress, and recent messages so the agent can continue rather than start from scratch. Multiple agents support different workflows, build for full-permission development, plan for read-only analysis, and compose for specs-driven development.
