About ChatGPT
ChatGPT remains the world's most widely used AI assistant, now powered by GPT-5.3-Codex (released February 5, 2026). This groundbreaking model is 25% faster than GPT-5.2 while using fewer tokens. GPT-5.3-Codex is the first OpenAI model to be "instrumental in creating itself"—early versions helped engineers debug its own training, manage deployments, and analyze test results.
The model is classified as "High capability" for cybersecurity under OpenAI's Preparedness Framework, trained specifically to identify software vulnerabilities. GPT-5 operates as a system of adaptive models (Instant, Thinking, Pro), automatically selecting the optimal variant for each task.
Context windows range from 8K tokens (Free) to 256K tokens (Pro/Enterprise). The integrated Codex agent provides end-to-end autonomous coding across the software development lifecycle. ChatGPT Pro ($200/mo) includes unlimited GPT-5.3 access, Sora 2 video generation, and priority compute. Note: GPT-4o is being retired on February 13, 2026, with users migrated to GPT-5.2+.

Editor's Review
Editor's Review (February 2026)
GPT-5.3-Codex represents a genuine leap forward. The self-improvement angle isn't just marketing—early versions of the model actually helped OpenAI engineers debug its own training pipeline. That's unprecedented.
What We Love:
• 25% faster than GPT-5.2 with fewer tokens (real cost savings)
• Cybersecurity capabilities are legitimately impressive—it's trained to find vulnerabilities
• The agentic coding works across entire projects, not just snippets
What Could Be Better:
• Pro tier at $200/mo is steep for individuals
• GPT-4o retirement (Feb 13) may disrupt some workflows
Who Should Use It:
Security researchers and enterprise developers will see the most value. For casual users, the Go tier at $8/mo is a great entry point.
