- • vision: basic, inferred from missing signals (low confidence).
- • Capability ratings are estimated from model size and name — this model hasn't been assessed by hand.
- • GGUF sizes come from community conversions matched by model name; equivalence and runtime support are not verified. MLX conversion availability is unverified.

Why?
- Model fits with approximately 9.8 GB of memory headroom.
- LM Studio supports hardware acceleration on this machine (Metal (Apple GPU)).
- Aider can connect to LM Studio (officially supported).
- 32K window; generation drops to 6–9 tok/s when it is full.
- Coding capability is below what interactive coding ideally needs — expect more mistakes or retries.
- Generation (7–10 tok/s) is slow for interactive coding.
- Ingesting a prompt of 14K tokens takes ≈3 min and each step ≈3 min; across ~4 calls a task takes ≈14 min.
Why “Borderline” rather than “Acceptable”?
- Prompt processing: Ingesting the first prompt (14K tokens) takes ≈3 min; each of the ~4 follow-up turns takes ≈3 min (≈14 min per task).
- Generation: Expected 7–10 tok/s at ~16K tokens of context. Coding with repository context is comfortable from about 28 tok/s.
- Context: 32K window; generation drops to 6–9 tok/s when it is full.
- Workload suitability: Coding capability is below what interactive coding ideally needs — expect more mistakes or retries.
