Our read: v0.1 is a bid to set the scoring rule for collaboration.","description":"Humans& reports 39.0% on CooperBench. The benchmark's public page lists GPT-5 and Claude Sonnet 4.5 at 25% and shows no Ampersand result. The company also says the model's interaction costs are higher than its peers'. Our hypothesis is that the release is about staking out a metric. The simpler explanation is that it is about collecting real usage data early. Either way, the numbers can't be checked from outside yet.","published_at":"2026-10-21T16:00:00.000Z","updated_at":"2026-10-21T16:00:00.000Z","record_date":"2026-10-21","topics":["reasoning"],"source_urls":["https://ampersand.humansand.ai/blog","https://openai.com/index/amp-beyond-coding","https://odyssey.systems/introducing-agora-2"],"language":"en","routes":{"html":"https://newruntime.com/analysis/humans-claims-39-on-cooperbench-a-benchmark-that-has-no-public-ampersand-entry/","markdown":"https://newruntime.com/analysis/humans-claims-39-on-cooperbench-a-benchmark-that-has-no-public-ampersand-entry.md","json":"https://newruntime.com/analysis/humans-claims-39-on-cooperbench-a-benchmark-that-has-no-public-ampersand-entry.json"},"author":{"role":"author","name":"Andrey Reshetnikov","profile":"https://newruntime.com/owner-profile.md","profile_json":"https://newruntime.com/owner-profile.json","same_as":["https://www.linkedin.com/in/reshetnikov1/","https://t.me/lapetuse"]},"editorial_provenance":{"desk":"authorial","target_ref":"story_cluster:humans-ampersand-v0-1-collaborator-model-release-b66567ded291","authorial_article_id":"9e934cd8-c807-4ed2-a205-f333df7311a5"},"next_reads":[{"type":"topic","path":"/topics/reasoning/","url":"https://newruntime.com/topics/reasoning/","title":"Reasoning","reason":"Explore the reasoning topic hub.","media_type":"text/html","markdown_url":"https://newruntime.com/topics/reasoning.md","json_url":"https://newruntime.com/topics/reasoning.json"},{"type":"collection","path":"/analysis/","url":"https://newruntime.com/analysis/","title":"Analysis","reason":"Open the latest authorial analysis.","media_type":"text/html","json_url":"https://newruntime.com/analysis.json"},{"type":"collection","path":"/source-ledger.json","url":"https://newruntime.com/source-ledger.json","title":"Source Ledger","reason":"Inspect the public source evidence graph.","media_type":"application/json"}]}
