Side A is a well-targeted improvement to pair selection heuristics—adding smarter bridge prioritization, rank-based refinement ordering, and corresponding tests—but its impact is confined to one algorithm, whereas Side B establishes a broader, lasting platform redesign.\"}","refusal":null,"reasoning":null,"reasoning_details":[{"type":"reasoning.encrypted","data":"gAAAAABqXSXcijvRT6A7TAl2EiZ4juwF-iqG7iaKLEgyj7CZll7ibTbkOI5b4QznqM7YezuYaeXwUryu4WX_Jd4EOPKDlZ3IWDiInFnc1-0nWG8aBfbv3F2E-DMXzsda0q6q2yDhAabzo7Q7ahkoDvrF77ATHTZ8jUQHXnaiAhxv_fJS8oM_7sITOvpDyV1Svg82KP1B4yfmLf86TAX471W8xWiT-qMeyQGAsedAgMFkXpnVY0dv-xmkg_0svCDtouHph6UA5Z9CHYW6wl75J6lBSmWVYGkwTDY1j8IjApTUaHj0me3elVv90fECJLIdOwcvLmpD0P4rsmlIRcnvjyaoHPDKTAskvpzzdSilyuqOxqKJD5gqx0iB1NBi0B7yFu_0rnNul-R74-WDfdnSGyqfSHkwaotwIQyIhMulv5fRBOlmMPun-PlDCR8SEaN9ohR7HnDlaB_d1TyxOO1B4XQgY17HDD22sRP_gcDbu0v_f40dHPiV65qjQn5EnmCdSMMrNnJ4SxwrvjgHXcOd_7h93l6vLrTN4rwQT0RBskF2uZ9nMq1sgf96BoYntoFi8TjpbCuzmCeUBh-8YMx96wyg0Ih1P-UzWbwkMUUAY7RE7UmVx8z-iS9TEfV5LyOuW-_q6OQZG_9zwCvN9ti3S_XDoS3bEdSnLRfyhMSRpDZt1Z3BXiCjHEh5BPy9unXBGcp-wShHwU13s4G2nB1TMG1Wl2bgM9E-I9jGcgakABBe67EtUCPH6lCfzxrXtUiv_UGDdIibxszxh-xLfy_cQnbwGg_IHtQyLwPqiOSiNjVPjiFLSpPTWiJlTlaf7d-E2GAOPwx1qLrHWoJdIXvalnOg7_E-2Lt-9kOQs8at-TG2i4V1fd246CDEtzfaGcx-t6ETAQCSvZRfJe-2d4mtullxenL82iECIfEoQoYdkFB6WFLiuwIKobQ=","format":"openai-responses-v1","id":"rs_0f5167bb837b89be016a5d25dbe91c8196ba802e3cc01377d8","index":0}]}}],"usage":{"prompt_tokens":64911,"completion_tokens":130,"total_tokens":65041,"cost":0.328455,"is_byok":false,"prompt_tokens_details":{"cached_tokens":0,"cache_write_tokens":0,"audio_tokens":0,"video_tokens":0},"cost_details":{"upstream_inference_cost":0.328455,"upstream_inference_prompt_cost":0.324555,"upstream_inference_completions_cost":0.0039},"completion_tokens_details":{"reasoning_tokens":0,"image_tokens":0,"audio_tokens":0}}}
