OpenAI Unveils GPT-5.2-Codex: Next-Level Coding Power!
OpenAI announced GPT-5.2-Codex, an agentic coding model optimized from GPT-5.2 for complex, long-horizon software engineering tasks and improved agentic performance in terminal and Windows environments. The model delivers context compaction, better tool calling and factuality, enhanced vision for interpreting screenshots and diagrams, and stronger cybersecurity capabilities compared with prior Codex releases. OpenAI is rolling out GPT-5.2-Codex today to paid ChatGPT users on Codex surfaces, plans API access in the coming weeks, and will run an invite-only trusted-access pilot for vetted defensive security professionals and organizations. The company highlights a recent real-world example in which a Privy security engineer used GPT-5.1-Codex-Max to help discover and responsibly disclose React vulnerabilities (including CVE-2025-55182), and emphasizes added safeguards and tighter access controls to mitigate dual-use risks as capabilities advance.
A major platform (OpenAI) released an advanced coding model with materially stronger cybersecurity capabilities and a staged deployment plan; this affects developer productivity, vulnerability research, and dual-use risk management across the industry.

OpenAI Launches GPT-5.5 and Codex Superapp
OpenAI released GPT‑5.5, the successor to GPT‑5.4, positioning the model as an agentic AI designed to work autonomously across multi-step tasks with a focus on software development and scientific collaboration. OpenAI says GPT‑5.5 can plan, use tools, navigate user interfaces, switch between tools, and verify its work; nearly 200 early‑access partners provided feedback. The model is available in ChatGPT and Codex across paid tiers (Plus, Pro, Business, Enterprise; Codex: Edu and Go) with API access coming soon. OpenAI published benchmark results showing lead performance in several tests (e.g., Terminal‑Bench 2.0: 82.7%), while some comparisons exclude competitors and independent evaluations are still pending. GPT‑5.5 is reported to be more expensive than GPT‑5.4 but more token‑efficient; OpenAI says it will ship the model with stricter safety controls. The article notes limited transparency in cross‑vendor benchmarking and highlights product variant GPT‑5.5 Pro for higher‑accuracy tasks.
