They should be concerned with open weight models that don’t run on consumer hardware. The larger models from Qwen (Qwen Max) and ZLM (GLM and GLM air) perform not too far from Claude Sonnet 4 and GPT-5. ZLM offers a $3 plan that is decently generous. I can pretty much replace it over Sonnet 4 in Claude Code (I swear, Anthropic has been nerfing Sonnet 4 for people on the Pro plan).
You can run Qwen3-coder for free upto 1000 requests a day. Admittedly not state of the art but works as good of 5o-mini
I believe regular people will not change from chatGPT if it has some ads. I know people who use "alternative" wrappers that have ads because they aren't tech savvy, and I agree with the OP that this could be a significant amount of money We aren't 700 million people that use it.
