Every tier slot in the planner where this model is a top or alternate pick. Pulled live from planner.js — when the planner refreshes, this table stays current.
The call
Phone-class multimodal model built on the same Qwen 3.5 foundation as the medium tier. Non-thinking by default. Runs anywhere, including CPU-only setups.
When not to use: Anything requiring multi-step reasoning or code beyond snippets — at 2B it hallucinates structure on anything non-trivial. Utility model, not a thinker.
Runner notes
Ollama tag `qwen3.5:2b` (Q4_K_M default). Runs on phones, Raspberry Pi 5, and anything else with 4 GB+ RAM.
