Pokee-Isaac 28B Report - MRCR v2 8-needle 1M: leaderboard
OpenAI MRCR v2 multi-round coreference, 8-needle split: eight near-identical requests and their responses are hidden in a long synthetic conversation in the 1M-token bin, and the model must reproduce the response to the specified instance; 30 paired samples, official random-prefix filter and SequenceMatcher score on a 0-1 scale. Models with no usable output at this length are left out. From Pokee AI's Pokee-Isaac 28B technical report (September 10, 2026 revision): Pokee ran every listed model itself through hosted APIs under one harness, with each peer's default temperature (unless a benchmark section fixes one) and a high thinking level where available; exhausted retries, context overflows and verifier failures count as zero. Higher is better.
Metric: Score (0-1). Source: pokee.ai. Saturation forecast: Around 2029. 4 models tracked.
