Its model card reports parity with the base model on BenchLocal while using fewer tokens, and offers routes to run it locally; those are useful claims for builders to test, not independent proof of a general capability gain.","published_at":"2026-11-08","updated_at":"2026-11-08","record_date":"2026-11-08","date_kind":"published_at","topics":["coding-agents","open-models","models"],"entities":["Continuity Research","Tess-4.5-27B","Qwen3.8-27B","Hugging Face","BenchLocal"],"related_patterns":[],"novelty_label":"new_fact","what_changed":"Continuity Research released a separate 27B Apache-2.0 fine-tune of Qwen3.8-27B specifically for agentic coding.","prior_refs":["https://newruntime.com/posts/nous-research-released-arete-27b-a-qwen3-8-a169fd/"],"source_url":"https://huggingface.co/migtissera/Tess-4.5-27B","source_urls":["https://huggingface.co/migtissera/Tess-4.5-27B"],"schema_version":"newruntime-agent-readable-v0.2","stable_id":"post:continuity-research-released-tess-4-5-27b-a-1c8d16","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/continuity-research-released-tess-4-5-27b-a-1c8d16/","markdown":"https://newruntime.com/posts/continuity-research-released-tess-4-5-27b-a-1c8d16.md","json":"https://newruntime.com/posts/continuity-research-released-tess-4-5-27b-a-1c8d16.json"},"markdown_url":"https://newruntime.com/posts/continuity-research-released-tess-4-5-27b-a-1c8d16.md","next_reads":[{"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":"topic","path":"/topics/open-models/","url":"https://newruntime.com/topics/open-models/","title":"Open Models","reason":"Explore the open-models topic hub.","media_type":"text/html","markdown_url":"https://newruntime.com/topics/open-models.md","json_url":"https://newruntime.com/topics/open-models.json"},{"type":"topic","path":"/topics/models/","url":"https://newruntime.com/topics/models/","title":"Models","reason":"Explore the models topic hub.","media_type":"text/html","markdown_url":"https://newruntime.com/topics/models.md","json_url":"https://newruntime.com/topics/models.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"}]}
