OpenAI - 发布GPT-5.2

OpenAI发布了更强大的模型系列 GPT-5.2 (Thinking/Pro)，旨在提升专业知识型工作和复杂多步骤任务的端到端执行能力。该模型在知识型工作任务（如GDPval）和软件工程（如SWE-Bench Pro/Verified）等多个基准测试中超越了行业水平。

OpenAI announced ChatGPT Go (global rollout) as a $8/month low-cost tier with “10× more messages,” file uploads, image creation, more memory, longer context, and “unlimited use of GPT-5.2 instant” (OpenAI). In parallel, OpenAI said it will start testing ads in Free + Go tiers, with principles: answers not influenced by ads, ads clearly labeled, and “conversations private from advertisers”
