Zhipu: glm-5.2:free
GLM-5.2 is the flagship model for the era of long tasks. It supports truly usable 1M context and has been tested to be capable of handling project-level engineering contexts. Long-term tasks are executed more stably and engineering standards are followed more reliably, resulting in a further increase in the success rate of development scenarios. A single task can complete the entire development chain from requirements to multi-platform deployable products.
