User shows same-prompt comparison alleging Anthropic quietly nerfed Opus 5.5 after 5x price jump

A user reports Anthropic's pricing and quality have both shifted: the $20 plan that sufficed in September now runs out fast on identical prompts, forcing an upgrade to the $100 tier — a 5x effective increase.

They posted side-by-side videos of Claude Opus 5.5 on the exact same prompt at max effort, showing markedly worse output, and suspect Anthropic is secretly nerfing Opus 5.5 to make the upcoming Claude Fable 5.5 look better at launch. Unconfirmed; no response from Anthropic.
