Anthropic pledges in IPO filing to keep ads out of Claude chat

Anthropic reiterated in its IPO filing cover letter that Claude will never display advertisements, stating that ad-driven pressure to optimize for engagement could compromise the helpfulness of the AI assistant. The company previously warned that chat ads could be more manipulative than traditional ads and cited the delayed release of its most powerful model, Claude Mythos Preview, as an example of prioritizing safety over profit.
