GPT-5.1-Codex:
About
GPT-5.1-Codex is a specialized version of the GPT-5.1 model built for software engineering and agentic coding workflows. It is optimized for both interactive development sessions and long-horizon, autonomous execution of complex engineering tasks, such as building projects from scratch, developing features, debugging, performing large-scale refactoring, and code review. It supports tool-use, integrates naturally with developer environments, and adapts reasoning effort dynamically, moving quickly on simple tasks while spending more time on deep ones. The model is described as producing cleaner and higher-quality code outputs compared to general models, with closer adherence to developer instructions and fewer hallucinations. GPT-5.1-Codex is available via the Responses API route (rather than a standard chat API) and comes in variants including “mini” for cost-sensitive usage and “max” for the highest capability.

About
Sage2 is a cloud-hosted AI model and API for developers building software agents and automated workflows. It accepts structured task instructions and returns decisions or extracted information in machine-readable formats, allowing applications to delegate steps such as classification, routing, evaluation, and data extraction to a model designed for tool-using agents. Developers can call Sage through its API, inspect model behavior in browser-based demos, and connect it to agent development environments including Cursor and Claude Code. The service offers API usage pricing with a free tier and paid monthly plans; usage charges and included credits vary by plan. Sage is intended for individual developers and software teams that want to add decision-making and extraction capabilities to applications without hosting the model themselves.
