Its reported results suggest that specialized post-training can make a very small model useful for bounded local-assistant tasks, but the announcement’s benchmarks are not independent evidence of production reliability.","published_at":"2026-11-11","updated_at":"2026-11-11","record_date":"2026-11-11","date_kind":"published_at","topics":["tool-use","agent-workflows"],"entities":["Tether AI Research","BotPsy","Qwen3.5-0.8B","Qwen3.5-2B-Think","QVAC SDK","llama.cpp"],"related_patterns":["agent-economics-moves-to-completed-work"],"novelty_label":"new_fact","what_changed":"Tether AI Research introduced BotPsy, a 0.8B-parameter model for on-device function calling and agentic workflows, built on Qwen3.5-0.8B.","prior_refs":["https://newruntime.com/posts/meta-released-muse-glimmer-30b-an-open-weight-aa31c3/"],"source_url":"https://huggingface.co/blog/qvac/botpsy","source_urls":["https://huggingface.co/blog/qvac/botpsy"],"schema_version":"newruntime-agent-readable-v0.2","stable_id":"post:botpsy-on-device-personal-assistant-with-a-sub-92ce02","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/botpsy-on-device-personal-assistant-with-a-sub-92ce02/","markdown":"https://newruntime.com/posts/botpsy-on-device-personal-assistant-with-a-sub-92ce02.md","json":"https://newruntime.com/posts/botpsy-on-device-personal-assistant-with-a-sub-92ce02.json"},"markdown_url":"https://newruntime.com/posts/botpsy-on-device-personal-assistant-with-a-sub-92ce02.md","next_reads":[{"type":"topic","path":"/topics/tool-use/","url":"https://newruntime.com/topics/tool-use/","title":"Tool Use","reason":"Explore the tool-use topic hub.","media_type":"text/html","markdown_url":"https://newruntime.com/topics/tool-use.md","json_url":"https://newruntime.com/topics/tool-use.json"},{"type":"topic","path":"/topics/agent-workflows/","url":"https://newruntime.com/topics/agent-workflows/","title":"Agent Workflows","reason":"Explore the agent-workflows topic hub.","media_type":"text/html","markdown_url":"https://newruntime.com/topics/agent-workflows.md","json_url":"https://newruntime.com/topics/agent-workflows.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":"/sources/","url":"https://newruntime.com/sources/","title":"Sources","reason":"See the original sources this archive cites.","media_type":"text/html"}]}
