Trade-offs
Llama 3.2 3B Instruct
Small enough for a laptop CPU or a 6 GB card, and still coherent. A sensible target for edge deployment.
Strengths
- Runs almost anywhere
- Very fast
- Cheap to fine-tune
Limitations
- Limited reasoning depth
- Hallucinates more than 7B+ models
Llama 3.1 8B Instruct
The most widely supported open model there is. If a tool, adapter or tutorial exists, it was written for this one first.
Strengths
- Unmatched ecosystem support
- 128k context
- Very stable fine-tuning behaviour
Limitations
- Benchmarks now behind newer 7–9B models
- Community licence with an acceptable-use policy
