You can see the very different response by OpenAI: https://openai.com/index/our-approach-to-advertising-and-exp.... ChatGPT is saying they will mark ads as ads and keep answers "independent," but that is not measurable. So we'll see.
For Anthropic to be proactive in saying they will not pursue ad based revenue I think is not just "one of the good guys" but that they may be stabilizing on a business model of both seat and usage based subscriptions.
Either way, both companies are hemorrhaging money.
(My gut feeling tells me Claude Code is currently underpriced with regards to inference costs. But that's just a gut feeling...)
