Addendum to GPT-5 system card: GPT-5-Codex Addendum op GPT-5-systeemkaart: GPT-5-Codex
This addendum to the GPT-5 system card shares a new model: GPT-5-Codex, a version of GPT-5 further optimized for agentic coding in Codex. GPT-5-Codex adjusts its thinking effort more dynamically based on task complexity, responding quickly to simple conversational queries or small tasks, while independently working for longer on more complex tasks. Dit addendum op de GPT-5-systeemkaart deelt een nieuw model: GPT-5-Codex, een versie van GPT-5 die verder is geoptimaliseerd voor agentic coding in Codex. GPT-5-Codex past zijn denkvermogen dynamischer aan op basis van de complexiteit van de taak: het reageert snel op eenvoudige conversatievragen of kleine taken, terwijl het zelfstandig langer doorwerkt aan complexere taken.

- Track this as a OpenAI update, not just a standalone headline. Bekijk dit als OpenAI-update, niet alleen als losse headline.
- Useful for builders who need to understand API, coding, or workflow changes. Nuttig voor bouwers die API-, code- of workflowwijzigingen willen begrijpen.
- Likely worth revisiting after people have used the release in practice. Waarschijnlijk de moeite waard om opnieuw te bekijken zodra mensen het in praktijk gebruiken.
