Builders should focus on execution‑path engineering first, treating tool‑call topology as a core performance budget.","published_at":"2026-09-25T08:00:00.000Z","updated_at":"2026-09-25T08:00:00.000Z","record_date":"2026-09-25","topics":["orchestration"],"source_urls":["https://www.cerebras.ai/blog/the-rise-of-slow-personal-assistants","https://z.ai/blog/glm-built-its-inference-infrastructure","https://arxiv.org/pdf/2406.11695"],"language":"en","routes":{"html":"https://newruntime.com/analysis/why-tool-call-reduction-not-bigger-models-will-be-the-decisive-lever-for-fast/","markdown":"https://newruntime.com/analysis/why-tool-call-reduction-not-bigger-models-will-be-the-decisive-lever-for-fast.md","json":"https://newruntime.com/analysis/why-tool-call-reduction-not-bigger-models-will-be-the-decisive-lever-for-fast.json"},"editorial_provenance":{"desk":"authorial","target_ref":"story_cluster:cerebras-benchmarks-and-optimization-methods-for-faster-ai-personal-assistants-fe9973bbe0d8","authorial_article_id":"abc275ca-067a-4e5b-bc00-d6b73358c0e0"},"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"]}}
