Anthropic was founded by a group of 7 former OpenAI employees who left over differences in opinions about AI Safety. I do not see any public documentation that the specific difference in opinion was that that group thought that OpenAI was too focused on scaling and that there needed to be a purely safety-focused org that still scaled, though that is my impression based on conversations I've had.

But regardless anthropic reasoning was extremely in the intellectual water supply of the Anthropic founders, and they explicitly were not aiming at producing a human-like model.

They tried to fire Sam Altman and left to form their own company when that didn't work. https://simonwillison.net/2023/Nov/22/before-altmans-ouster-...
