The useful lesson for AI builders is that cache-read pricing can dominate the actual cost of an agent loop, making headline input and output rates an incomplete procurement metric.","published_at":"2026-10-27","updated_at":"2026-10-27","record_date":"2026-10-27","date_kind":"published_at","topics":["anthropic","claude","coding-agents"],"entities":["OpenAI","Anthropic","GPT-5.6 Luna","GPT-6.1 Sol","Claude Opus 5.5","DeepSeek Flash V4.1","OpenRouter","Max Woolf"],"related_patterns":["agent-economics-moves-to-completed-work"],"novelty_label":"new_angle","what_changed":"Explains the broader wave of OpenAI and Anthropic price cuts through a timeline and the outsized role of cache-read costs in agentic coding.","prior_refs":["memory:a6ffc9e0-8b45-8319-ab42-deb8ca342e1f","memory:80025f1d-9247-89a9-a966-e87ca7d6ace9"],"source_url":"https://minimaxir.com/2026/10/cheap-llms","source_urls":["https://minimaxir.com/2026/10/cheap-llms"],"schema_version":"newruntime-agent-readable-v0.2","stable_id":"post:a-dive-into-why-openai-anthropic-cut-llm-8966c7","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/a-dive-into-why-openai-anthropic-cut-llm-8966c7/","markdown":"https://newruntime.com/posts/a-dive-into-why-openai-anthropic-cut-llm-8966c7.md","json":"https://newruntime.com/posts/a-dive-into-why-openai-anthropic-cut-llm-8966c7.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":"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/coding-agents/","url":"https://newruntime.com/topics/coding-agents/","title":"Coding Agents","reason":"Explore the coding-agents topic hub.","media_type":"text/html","markdown_url":"https://newruntime.com/topics/coding-agents.md","json_url":"https://newruntime.com/topics/coding-agents.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"}]}
