GPT-5.6 Terra has been the primary Coder in my software factory for weeks, I've been using GPT-5.6 Sol as the planner and Terra for everything else. It works extremely well on very complex code.
GLM-5.3-Flash, released today, is an open-weight model with the same level of intelligence as GPT-5.6 Terra but 6x cheaper.
Its also become viable and practical to own this level of intelligence.
GLM-5.3-Flash will become available from serverless model vendors that host the model here in the states and offer true zero data retention. Or you can run it on GPUs you control.
GLM-5.3-Flash can also likely run on pro-sumer machines like the new 512GB unified memory Mac studio that was announced by Apple yesterday.
