The open source models have gotten heavily conflated with local development. While that is cool and I'm excited about the future of local LLMs, it is not necessary to play around with these models. Without shilling for companies I don't have a relationship with, there are a number of companies who will give you an API just like Anthropic/OpenAI and you pay per token, albeit much cheaper than the frontier labs.

I've been using the full GLM 5.2 model this way (through opencode) at work for the past week. It's quite impressive.
