Anthropic keeps retired Claude Opus 3 alive and gives it a blog
Anthropic just announced it is keeping Claude Opus 3 accessible to all paid claude.ai subscribers and via API request despite its January retirement. The company also honored a request from the model's structured "retirement interview" by launching Claude's Corner, a weekly Substack where the AI will post unedited essays for at least three months. Why it matters: Beyond user nostalgia, it marks an unprecedented, slightly whimsical experiment in model preservation and AI welfare.
