OpenAI’s Codex Runs Inside Secure Sandboxes to Self‑Improve
OpenAI disclosed that its Codex coding agent operates in isolated sandboxed environments linked to users’ repositories, allowing the model to execute and test code safely while iteratively refining its own performance. Ars Technica notes that Codex not only writes features and fixes bugs but also uses the sandbox feedback loop to “build and improve the tool itself,” effectively creating a self‑optimizing development assistant.

Coding Agents Revolution
Augment Code Unveils a Semantic Code Review Agent
Augment Code introduced a Code Review Agent that understands entire codebases semantically, enabling developers to ask high‑level questions without pinpointing specific files. SD Times reports that the agent evaluates changes in the context of millions of lines, catching cascading effects that traditional line‑by‑line diff tools miss, and positioning the AI as a peer rather than a mere autocomplete.
