Bonsai 27B (27B, Apache 2.0) is the best all-round pick at 5 tok/s on the M1. If you want maximum speed, SmolLM3 3B hits 65 tok/s; for maximum capability, Maple Preview 20B-A1B still fits in 8 GB.
About 18 of the 80 models in the LLMCheck leaderboard fit in 8 GB of unified memory, from compact models up to Bonsai 27B (27B).
Not comfortably. A 70B model in Q4 needs ~40–44 GB; with 8 GB you should stick to models up to ~4 GB, such as Bonsai 27B. For 70B, look at a 48 GB+ Mac.
8 GB is enough for compact models like Gemma and Phi Mini, but tight for anything above ~8B. Because Apple Silicon uses unified memory, that figure is both your system RAM and your VRAM.
