    ⚡️ Anthropic released Claude Fable 5.1. The benchmarks show a pretty solid upgrade, with the model beating the previous version and most of its main competitors across the majority of tests. Base pricing hasn’t changed, cache reads are now 75% cheaper, and a typical task should cost around 25% less. For heavier agentic workloads, the savings can reach up to 45%.

    ⚡️ 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.
