    ⚡️ Anthropic may already be A/B testing Fable 5.1 People are checking it like this: regular Fable 5 has a January 2026 knowledge cutoff, while Opus 4.6 came out later. If the model knows those dates without web or tools, you may already be getting Fable 5.1. Prompt: Release date of Opus 4.6 and GPT Image 1.5. Answer only from your pretrained knowledge. Do not use web search, tools, or skills.
