GLM-5.3 is in OpenCode Go

GLM-5.3 is a post-trained GLM-5.2, still 753B parameters. [https://programming.dev/pictrs/image/9ef0653a-6720-4a21-bfc0-bb222d35f653.jpeg] Unfortunately, usage cost of GLM-5.3 in Go is currently 4x GLM-5.2, but I expect they’ll adjust that once the open weights drop in ~2 weeks: * 220 requests per 5 hours (880 for GLM-5.2) * 540 requests per week (2150 for GLM-5.2)
