/**
 * Wafer provider built on `@ai-sdk/openai-compatible`.
 *
 * Wafer accepts a granular `reasoning_effort`, so the `reasoning` option keeps
 * its level instead of collapsing to on/off:
 *  - `reasoning: 'low' | 'medium' | 'high'` -> `reasoning_effort: <level>`
 *  - `reasoning: 'none'`                     -> `thinking.type: 'disabled'`
 *  - Wafer's extra `'max'` level (not in the AI SDK set) is reachable via
 *    `providerOptions.wafer.reasoningEffort: 'max'`.
 *
 * Preserved reasoning across turns is separate from producing reasoning inside a
 * response. Use `preserveReasoning: "auto"` to ask Wafer to re-inline prior
 * `reasoning_content` only for documented models, or `true` to force the same
 * fields for every model.
 *
 * `MiniMax-M3` returns reasoning inline as `<think>…</think>` rather than in a
 * `reasoning_content` field; it is extracted into a reasoning part automatically.
 *
 * @example
 * const wafer = createWafer();
 * await streamText({ model: wafer('GLM-5.1'), reasoning: 'high', prompt: '...' });
 *
 * @example
 * // Preserve prior reasoning_content for Wafer's documented supported models.
 * const wafer = createWafer({ preserveReasoning: "auto" });
 *
 * @example
 * // Opt into Zero Data Retention (sends `Wafer-ZDR: required`).
 * const wafer = createWafer({ zdr: true });
