Its reported performance is a substantial research step, but proving still costs far more GPU time than ordinary inference, so the release is an invitation to test and improve the approach rather than a ready-made production guarantee.","published_at":"2026-11-03","updated_at":"2026-11-03","record_date":"2026-11-03","date_kind":"published_at","topics":["anthropic"],"entities":["Anthropic","FlashProve","Llama 4 Maverick","vLLM","EPFL","MIT"],"related_patterns":["agent-security-moves-to-runtime-boundaries"],"novelty_label":"new_fact","what_changed":"Anthropic now describes FlashProve, a zkSNARK system for proving LLM inference, with reported throughput and proof-size benchmarks; the prior covers trusted-VM confidential inference.","prior_refs":["memory:c59a59bc-c20e-8f7e-a085-427e28bea062"],"source_url":"https://www.anthropic.com/research/provable-inference","source_urls":["https://www.anthropic.com/research/provable-inference"],"schema_version":"newruntime-agent-readable-v0.2","stable_id":"post:anthropic-releases-flashprove-an-open-source-zksnark-system-79d880","status":"published","visuals":[],"editor":{"role":"editor","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"]},"routes":{"html":"https://newruntime.com/posts/anthropic-releases-flashprove-an-open-source-zksnark-system-79d880/","markdown":"https://newruntime.com/posts/anthropic-releases-flashprove-an-open-source-zksnark-system-79d880.md","json":"https://newruntime.com/posts/anthropic-releases-flashprove-an-open-source-zksnark-system-79d880.json"},"next_reads":[{"type":"topic","path":"/topics/anthropic/","url":"https://newruntime.com/topics/anthropic/","title":"Anthropic","reason":"Explore the anthropic topic hub.","media_type":"text/html","markdown_url":"https://newruntime.com/topics/anthropic.md","json_url":"https://newruntime.com/topics/anthropic.json"},{"type":"collection","path":"/posts/","url":"https://newruntime.com/posts/","title":"Field Notes","reason":"Open the latest editorial analysis.","media_type":"text/html","json_url":"https://newruntime.com/posts.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"}]}
