OpenCode free stack: Space Bunny (M3.1 Flash) covers 1M long context
A user describes their OpenCode setup after replacing Muse Spark 1.3: GLM 5.3 Flash for planning, DeepSeek V4.1 Flash for building (~8 hours of free quota), Space Bunny's 1M window when context runs out, and MiMo 2.6 Flash as backup.
a few more things i’ve learned replacing Muse Spark 1.3 in OpenCode: 1. DeepSeek V4.1 Flash can last me ~8 hours of work before i hit the daily free limit, as long as i’m not constantly spawning subagents. 2. the 200K context cap is manageable, but i usually hit compaction several times during a long session. for bigger repos, that matters. 3. when context starts becoming the bottleneck, i switch to Space Bunny for the 1M window instead of forcing DeepSeek through repeated compactions. 4. for planning, i still prefer GLM 5.3 Flash, but i don’t use it for everything. on simple build tasks, it can take 2–3x more turns than DeepSeek. 5. if DeepSeek starts making weird implementation choices, MiMo 2.6 Flash is my fallback before i jump to a paid frontier model. right now my free stack is basically: GLM → plan DeepSeek → build Space Bunny → long context MiMo → backup
