Llama 3.2 3B Instruct
Lightweight 3B for edge and laptop deployment. Runs comfortably on 8GB VRAM at 30+ tok/s on Apple Silicon.
Positioning
The conversational small model. Llama 3.2 3B sounds more natural than every other model at this size, which makes it the right pick for chat-shaped applications running on 4–6 GB GPUs, low-end laptops, or as a fallback model in agent stacks.
Strengths
- 2 GB at Q4_K_M — runs on integrated GPUs and 4 GB cards with full context.
- Conversational tone is materially better than Phi-3.5 Mini at similar size.
- Same Llama license as the 8B and 70B — clean commercial path.
Limitations
- Weak on math and structured output — for those, Phi-3.5 Mini is the better edge model.
- Knowledge breadth is narrow — handles common-knowledge questions but fails on long-tail facts.
- No vision — for that pick the 11B Vision variant instead.
Real-world performance on RTX 4090
- Q4_K_M (2.0 GB): 145–170 tok/s decode, TTFT under 40 ms
- Q5_K_M (2.4 GB): 130–155 tok/s
- Q8_0 (3.4 GB): 110–135 tok/s
Should you run this locally?
Yes, for edge devices, chat assistants on integrated graphics, agent-loop fallback models, or any rig where 4 GB is the VRAM ceiling. No, for code, math, or any task where structured output matters — pick Phi-3.5 Mini.
How it compares
- vs Phi-3.5 Mini (3.8B) → Llama 3.2 3B wins on chat naturalness; Phi wins on math and structured output. Pick by job.
- vs Llama 3.2 1B → 3B is materially smarter; 1B exists for genuinely tight footprints (under 2 GB).
- vs Gemma 3 4B → close; Gemma 3 4B is slightly more capable on multilingual + general chat. Both excellent.
- vs Qwen 2.5 3B → Llama 3.2 3B has the more permissive license; capability is roughly even.

›Why this rating
7.4/10 — Meta's edge-friendly 3B is the best general 3B model available, and the right pick when you need conversational naturalness in low VRAM. Loses points on math/structured tasks where Phi-3.5 Mini is stronger at similar size.
Overview
