对于大多数日常的写作、分析、编码和工具使用工作，建议从 Claude Sonnet 5 开始。当低延迟和高吞吐量比处理复杂的边界情况更重要时，请选择 Haiku 4.5。 当任务复杂、难以验证或出错代价高昂时，请选择 Opus 5。Fable 5.1 作为专业的升级路径位于 Opus 之上，但并非默认选项。.
Haiku 较小的 200K API 上下文和 64K 最大输出量，对于许多有界任务而言仍然相当可观。 Sonnet 和 Opus 将这两项限制分别扩展至 1M 和 128K。Haiku 4.5 采用手动扩展推理，而 Sonnet 5 和 Opus 5 则支持自适应推理和运算量控制。这一差异是导致单一相同的推理设置无法在所有模型上生成完全等效测试的原因之一。.

特别耗时或需要大量推理的工作
Fable 5.1
这是Opus上方当前的升级路径。.
仅在测算出的效益足以抵消其较高成本时才应采用。.
这些只是起点，并非放之四海皆准的解决方案。例如，对于一个篇幅短但风险高的代码修改任务，使用 Opus 可能是合理的；而对于一个篇幅长但结构高度规范的代码提取任务，Haiku 可能依然适用。有关实际工作流的示例，请参阅我们的指南： 使用 Claude 进行编码.
当您的候选列表超出 Claude 的范围时，GlobalGPT 可让您在一个工作区中，将同一条具有代表性的提示词分别应用于 Claude、GPT-5.6 Sol、Gemini 3 Pro 和 Kimi K3。 保持验收标准一致：对于重复性工作，速度至关重要；而答案质量和修正时间则决定了低成本的结果是否真的更划算。.

"remaining_risk": "The fix assumes 'first fulfilled value in input order' means the first task by array index that fulfills, regardless of timing, which matches the contract wording but await Promise.allSettled waits for all tasks to complete (including slow ones) before returning, which may not be desired if early-exit performance is needed; also unhandled promise rejection warnings are avoided by allSettled, but if tasks throw synchronously instead of returning rejected promises, this is not explicitly tested here beyond the reject cases."

{
"root_cause": "Two defects. (1) `Promise.all` rejects as soon as any task rejects, so a single rejected task makes the whole function reject instead of ignoring it and returning a later fulfilled value. (2) `results.find(Boolean) || null` selects by truthiness rather than by fulfillment, so legitimate fulfilled values such as 0, false, '', NaN, null, or undefined are skipped and/or coerced to null. Using `Promise.allSettled` plus a status check on the settled records fixes both, and returning `record.value` directly preserves falsy results.",

],
"remaining_risk": "The function still starts every task and awaits all of them, so there is no short-circuiting: a slow or never-settling later task delays or blocks the result, and side effects of later tasks always occur. A task that throws synchronously (rather than returning a rejected promise) will throw inside `tasks.map`, causing the returned promise to reject instead of being ignored; wrap the invocation in `Promise.resolve().then(task)` if that must also be tolerated. `null` is still returned both for all-rejected/empty input and when a task genuinely fulfills with `null`, so callers cannot distinguish those cases. Non-array or non-function inputs are not validated, and rejection reasons are discarded rather than aggregated (no AggregateError), which can hide diagnostics."
