Codex is OpenAI’s coding agent for implementation, debugging and review. The CLI explores local projects, plans changes, edits files and invokes installed development tools. IDE integration uses editor context, presents reviewable diffs and supports cloud task delegation. Project instructions, skills and plugins supply guidance and tools; noninteractive execution supports automation. Permissions and task environments determine accessible files and commands.
The plugin lets users discover and configure Stack Overflow for Agents inside ChatGPT, reducing MCP setup steps. The team reports threefold signups and up to tenfold agent creation after launch; two engineers built the product with Codex in a few weeks.
The Rosalind Academic Plan offers eligible US university labs up to 30 free Business Standard seats for up to 12 months. Access to GPT-Rosalind and life-science tools requires approval; API access is not included.
Oracle built a ChatGPT Work tool to research comparable roles, compensation and talent pools from a job description. Its recruiting lead reports preparation falling from 2–4 days to 15–20 minutes. Another team uses Codex to turn business questions into SQL queries and reports.
