The "Thinking" Tier: OpenAI Releases GPT-5.2 Family

OpenAI has quietly rolled out the GPT-5.2 model family, introducing a tiered system: Instant, Thinking, and Pro. The "Thinking" tier is making waves for its ability to match human experts on roughly 71% of complex reasoning tasks. Unlike previous models, GPT-5.2 utilizes advanced self-verification loops, allowing it to "check its own work" and reduce hallucinations in critical professional workflows like legal analysis and software engineering.
