Replacing Muse Spark 1.3 in OpenCode's free stack with Space Bunny for long context
After Muse Spark 1.3 left OpenCode's free lineup, the author suggests GLM 5.3 Flash for planning, DeepSeek V4.1 Flash for coding, and Space Bunny (the anonymous M3.1 Flash) for 1M-context work where DeepSeek's 200K compacts too early.
Muse Spark 1.3 is gone from the free OpenCode lineup. here’s what i’d replace it with: 1. planning → GLM 5.3 Flash it’s slower, but i prefer it when the task is well-defined and i want a more structured plan first. 2. building → DeepSeek V4.1 Flash this is still my default for implementation. faster, more creative, and better suited for actually pushing code. 3. long-context work → Space Bunny the big advantage is the 1M context, especially when 200K on DeepSeek starts forcing compaction too early. 4. backup → MiMo 2.6 Flash i’d use it when DeepSeek gets too steer-heavy or starts producing weird implementation decisions. 5. best free combo → GLM plans, DeepSeek builds that’s the cleanest Muse replacement right now. Muse was really good. but the free stack is still very usable if you split the roles properly.
