Qwen 4.1 32B-A3B (32B, Apache 2.0) is the best all-round pick at 10 tok/s on the M3. If you want maximum speed, Phi-4 Mini hits 95 tok/s; for maximum capability, Qwen 4 still fits in 24 GB.
About 43 of the 79 models in the LLMCheck leaderboard fit in 24 GB of unified memory, from compact models up to Mistral Medium 4 (41B).
Not comfortably. A 70B model in Q4 needs ~40–44 GB; with 24 GB you should stick to models up to ~18 GB, such as Qwen 4.1 32B-A3B. For 70B, look at a 48 GB+ Mac.
24 GB is great for small-to-mid models (up to ~14B comfortably); for 30B+ you'll want 32 GB or more. Because Apple Silicon uses unified memory, that figure is both your system RAM and your VRAM.
