/** * Removes <think> blocks from the response content. * The sonar-reasoning-pro model outputs reasoning tokens in <think> blocks * that should be filtered out before returning to the client. * * Intentional behavior: We remove everything from the first "<think>" to the * last "</think>", treating any nested or stray think tags as a single block. * For example, the input "A <think>1</think> B <think>2</think> C" becomes * "A C" (note that " B " is removed). This is by design: there should only be * one reasoning block, and any accidental inner think tags must not interfere * with the primary goal of stripping the reasoning block entirely. * * @param {string} input - The raw content from the API response * @returns {string} The content with <think> blocks removed */ export function stripThinkContent(input: string): string { const open = "<think>"; const close = "</think>"; const firstOpen = input.indexOf(open); if (firstOpen === -1) return input; const lastClose = input.lastIndexOf(close); if (lastClose === -1 || lastClose < firstOpen) return input; const end = lastClose + close.length; return input.slice(0, firstOpen) + input.slice(end); }
