GPT-5.2-Codex System Card Addendum — new capabilities
AI Impact Summary
An addendum to the GPT-5.2-Codex system card signals a capability update for the GPT-5.2-Codex code-generation model. With no description provided, engineering teams should consult the official addendum to learn about new features, supported languages, context limits, and any changes to prompts or API semantics. If new coding capabilities are introduced, expect changes to output quality and workflow patterns, requiring updates to prompts, templates, and monitoring; validate in staging before production.
