OpenAI publishes details about GPT-5.2-Codex and shows how the Codex series has made significant jumps in capability, especially in evaluations related to cybersecurity. What does that mean for you, your product, or your tech curiosity? Let's keep it simple and useful.
What OpenAI announced
The post explains that, when charting performance on a key cybersecurity evaluation, there were three clear jumps: with GPT-5-Codex, then with GPT-5.1-Codex-Max, and now with GPT-5.2-Codex. That suggests a sustained improvement trajectory in security-related capabilities.
OpenAI clarifies that, although GPT-5.2-Codex still doesn't reach what their own framework calls the High level in cyber-capability, they're preparing as if future models might. In practice that means more precautions and controls both in the model and in the product.
What practical changes does this bring?
First: more safeguards. OpenAI says they've added extra controls in the model and in the product; those details are in the . And what can you expect day to day? For example:
