"descriptionEn": "Independent 2026-10-26 retest. Requested and returned model: LongCat-2.5-Preview; this does not establish release or checkpoint equivalence of the brief’s LongCat-2.5 name. Both groups explicitly request thinking enabled/disabled. temperature=0 is sent, but the vendor documents overriding it to 1.0 on / 0.7 off, so this is not a deterministic temperature-zero comparison. The Chat Completion documentation does not list named effort levels. A separate Responses API documents low and other levels, without a max name; those protocols are not mixed here. First attempts use 12,288 output tokens and a 600-second deadline. Up to two independent request queues overlap; local client latency is recorded without a speed ranking. All first attempts/failures are retained. Private reasoning content is omitted. Poster thinking-on attempt 2 encountered local ENOSPC while saving its result. Its dispatched slot remains interrupted; response, final usage, upstream outcome and measured duration are unknown. This is not a provider/model answer failure. Attempt 3 is independent. Token totals are lower bounds from reported usage; full consumption and cost are unknown. This section shows the first successful static/animated render in each mode, retaining failed first attempts and independent retries. The separate static archive does not add duplicate requests.",

Attempt 1 truncated; attempt 2 lost its result to local ENOSPC, so its quality and usage remain unknown. All six exact strings appear once.

Pale-green decoration, border and button shadow are polished, though the button sits close to the bottom border. October 24 is the fixed test date.",
