Fable 5
4 storiesFable 5 is a model from Anthropic that is often used as a benchmark for frontier-model performance. Recent coverage cited a Mozilla report finding Moonshot AI's Kimi K3 scored three points behind Fable 5 on a composite index at about 30% of the cost, a paper showing five Qwen3.8-27B models matching Fable 5 on hard LiveCodeBench problems through ledger-based zero-shot self-orchestration, and a r/LocalLLaMA question about when a GGUF build of Fable 5 will arrive.

Using the GVS5H method, five Qwen3.8-27B models collaborated via a Memdoor multi-agent workflow, achieving a mean score of 9.8/10 over five passes on the first ten LiveCodeBench Hard problems, surpassing Fable 5's standalone 8.0.
A short r/LocalLLaMA post asks when a GGUF quantized build of Fable 5 will be available, offering no details or official news. It reflects local-inference users' anticipation of quantized releases.
A paper and code repository introduce ledger-based zero-shot self-orchestration, in which fresh instances of one model split problems and coordinate through a shared filesystem. On the 100 latest hard LiveCodeBench problems, gains reach 25.6 points on pinned backends; orchestrated Qwen3.8 Flash Next hits 93.0% pass@1 versus Fable 5's 90.4% at 9% of the cost, and local Qwen3.8-27B rises from 66.8% to 92.4%. The authors note some models show no gain or worse.
A Mozilla report finds that the performance gap between Chinese open-weight models and US frontier models has narrowed to roughly 4.4 months. It highlights Moonshot AI's Kimi K3 scoring three points behind Anthropic's Fable 5 on a composite index while costing about 30% as much, suggesting open models are preferable for most routine workloads.
That is everything
