The next day Cline made the contributor model selectable. Docker browser sign-in is a documented non-interactive gap with an official API-key path; claimed 2.7x token savings from ported Muse instructions were not verified from a Cline-owned primary page.","published_at":"2026-11-08T00:00:00.000Z","updated_at":"2026-11-08T00:00:00.000Z","record_date":"2026-11-08","topics":["cli","tools","agents","research"],"source_urls":["https://research.meta.ai/blog/introducing-muse-code-and-muse-spark-1-2","https://research.meta.ai/static/muse-spark-1-2-methodology","https://artificialanalysis.ai/articles/muse-spark-1-2","https://dev.meta.ai/models/muse-spark-1-2","https://github.com/cline/cline/releases/tag/v4.1.6","https://github.com/cline/cline/releases/tag/cli-v3.0.51","https://github.com/cline/cline/releases/tag/sdk/sdk/v0.0.71","https://simonwillison.net/2026/Aug/5/muse-code-and-muse-spark-12/","https://dev.meta.ai/docs/muse-code/auth","https://dev.meta.ai/docs/muse-code","https://dev.meta.ai/docs/muse-code/extending","https://github.com/shelajev/muse-code-sbx-kit","https://github.com/meta-models/muse-code-sdk/issues/38"],"language":"en","routes":{"html":"https://newruntime.com/analysis/research-muse-spark-1-2-was-co-trained-with-muse-code-cline-shipped-the-model-not-a/","markdown":"https://newruntime.com/analysis/research-muse-spark-1-2-was-co-trained-with-muse-code-cline-shipped-the-model-not-a.md","json":"https://newruntime.com/analysis/research-muse-spark-1-2-was-co-trained-with-muse-code-cline-shipped-the-model-not-a.json"},"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"]},"editorial_provenance":{"desk":"authorial","target_ref":"deep_research:5dfbe0f1-358c-4bde-a3d8-f584571bc785","authorial_article_id":"5dfbe0f1-358c-4bde-a3d8-f584571bc785"},"next_reads":[{"type":"topic","path":"/topics/tools/","url":"https://newruntime.com/topics/tools/","title":"Tools","reason":"Explore the tools topic hub.","media_type":"text/html","markdown_url":"https://newruntime.com/topics/tools.md","json_url":"https://newruntime.com/topics/tools.json"},{"type":"topic","path":"/topics/agents/","url":"https://newruntime.com/topics/agents/","title":"Agents","reason":"Explore the agents topic hub.","media_type":"text/html","markdown_url":"https://newruntime.com/topics/agents.md","json_url":"https://newruntime.com/topics/agents.json"},{"type":"collection","path":"/analysis/","url":"https://newruntime.com/analysis/","title":"Analysis","reason":"Open the latest authorial analysis.","media_type":"text/html","json_url":"https://newruntime.com/analysis.json"},{"type":"collection","path":"/sources/","url":"https://newruntime.com/sources/","title":"Sources","reason":"See the original sources this archive cites.","media_type":"text/html"}]}
