GLM 5.2
GPT 5.6 Sol ProGLM-5.2 is Z.ai’s flagship model for the era of long-horizon tasks. With a truly usable 1M-token context window, it can handle project-level engineering context, execute long-running tasks more reliably, follow engineering standards more consistently, and complete the full development workflow from requirements to multi-platform deployment in a single task.
gpt-5.6-sol-pro is OpenAI's multimodal model, designed for complex reasoning and generation tasks. It supports text and image inputs alongside an extensive 1,050,000-token context window. Compared with GPT-5.6 Sol, it is served with reasoning.mode set to pro for higher-quality responses on complex tasks.
