Benchmark rows are figures the model's authors published, not ModelLM measurements, and the two models may not have been evaluated under identical conditions.
Trade-offs
Llama 3.2 1B Instruct
A genuinely tiny model for classification, routing and extraction rather than open-ended chat.
Strengths
- Runs on a phone or Raspberry Pi
- Fine-tunes in minutes
- Excellent for narrow tasks
Limitations
- Not usable as a general assistant
- Needs fine-tuning to be useful
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
