Output tokens cost $3.94 per million on GLM 5.2 and $30.00 per million on GPT Image 2. Input tokens cost $1.13 per million on GLM 5.2 and $5.00 per million on GPT Image 2. Cached input tokens are billed at $0.28 per million on GLM 5.2 and $5.00 per million on GPT Image 2.
GLM 5.2
GPT Image 2GLM-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-image-2 is OpenAI's latest cutting-edge image generation model. Key value adds include better performance, quality, editing controls, and face preservation. (Currently the model's image generation time may be >5 minutes; it is recommended to set the client timeout to ≥10 minutes.) The model supports high input_fidelity and adding/removing one aspect of the image while retaining others. This model includes improvements in aspect ratio, resolution, and editing capabilities.
