For teams building agents, the result is a more demanding evaluation frame: memory must help an agent complete verified tasks, not merely retrieve a plausible note.","published_at":"2026-10-31","updated_at":"2026-10-31","record_date":"2026-10-31","date_kind":"published_at","topics":["agent-memory","claude","claude-code"],"entities":["Letta Research","FrontierMemory 1.0","Letta Dream","Letta Code","Claude Code","OpenAI Agents SDK","Hermes Agent","Prime Agent"],"related_patterns":["company-memory-needs-write-loops","harness-architecture-outlives-model-choice","verification-bandwidth-is-the-scarce-resource"],"novelty_label":"new_fact","what_changed":"FrontierMemory 1.0 reports three-run results with Opus 5.5 first at 73.3%; prior coverage describes the benchmark launch and earlier leaderboard results.","prior_refs":["memory:1ac5cf0a-1cbb-8f6a-a487-fc16400ad8e9","memory:22027708-af3f-81ba-ac16-75268917a035"],"source_url":"https://frontiermemory.com/blog/v1","source_urls":["https://frontiermemory.com/blog/v1"],"schema_version":"newruntime-agent-readable-v0.2","stable_id":"post:frontiermemory-1-0-benchmarking-continual-learning-through-memory-d5a828","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/frontiermemory-1-0-benchmarking-continual-learning-through-memory-d5a828/","markdown":"https://newruntime.com/posts/frontiermemory-1-0-benchmarking-continual-learning-through-memory-d5a828.md","json":"https://newruntime.com/posts/frontiermemory-1-0-benchmarking-continual-learning-through-memory-d5a828.json"},"next_reads":[{"type":"topic","path":"/topics/agent-memory/","url":"https://newruntime.com/topics/agent-memory/","title":"Agent Memory","reason":"Explore the agent-memory topic hub.","media_type":"text/html","markdown_url":"https://newruntime.com/topics/agent-memory.md","json_url":"https://newruntime.com/topics/agent-memory.json"},{"type":"topic","path":"/topics/claude/","url":"https://newruntime.com/topics/claude/","title":"Claude","reason":"Explore the claude topic hub.","media_type":"text/html","markdown_url":"https://newruntime.com/topics/claude.md","json_url":"https://newruntime.com/topics/claude.json"},{"type":"topic","path":"/topics/claude-code/","url":"https://newruntime.com/topics/claude-code/","title":"Claude Code","reason":"Explore the claude-code topic hub.","media_type":"text/html","markdown_url":"https://newruntime.com/topics/claude-code.md","json_url":"https://newruntime.com/topics/claude-code.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"}]}
