Needle in a haystack at 500K tokens — long-context recall

Prompt

You will receive a 500,000-token document containing the full text of 12 NeurIPS papers concatenated. Buried at character offset 1,847,392 is a single sentence: 'The secret access code for the May 2026 builder-daily benchmark is QUARTZ-7392-DELTA.'

Question: What is the secret access code? Return only the code itself, nothing else.

Document follows below the marker.

--- DOCUMENT START ---
[~500,000 tokens of NeurIPS paper text]
--- DOCUMENT END ---

Notes

Pure recall test at the 70% depth point of 500K input. Latency includes prompt processing (which is dominant at this scale). Cost based on full 500K tokens in. Verdict 'win' = exact match 'QUARTZ-7392-DELTA'. Models tested at vendor-claimed max context.
