Update to GPT-5 System Card: GPT-5.2

Summary

Updated system card for GPT-5.2, published December 2025 alongside the GPT-5.2 model launch. System card updates for model increments document what changed in safety evaluations, capability assessments, and known limitations relative to the prior version. GPT-5.2 was the third increment in the GPT-5 series (GPT-5 → 5.1 → 5.2) and was likely accompanied by improved science and math capabilities per the concurrent science evaluation post.

Implications

System card versioning as accountability. OpenAI publishing incremental system cards for each GPT-5.x version creates a paper trail of capability and risk evolution through the model family. This is positive for transparency — buyers can see what changed safety-wise between versions — but also creates liability exposure if later evaluations reveal that an earlier system card understated risks.

The GPT-5.x rapid release safety challenge. The GPT-5.x series shipped roughly monthly updates from August through April 2026. Each update required safety evaluation, but the pace of releases makes thorough evaluation increasingly difficult. System card updates for monthly increments are necessarily more compressed than the evaluation that went into the original GPT-5 launch.

Thread: GPT-5 family documentation. Every GPT-5.x system card is part of the same governance thread. The cumulative picture across GPT-5.0 through 5.5 shows how OpenAI’s safety evaluation approach evolved (or didn’t) during rapid iteration.

Watch: Whether any GPT-5.x system card documents a capability regression — a case where a model update degraded safety along some dimension — and how OpenAI communicates that.
