Trade-offs
Qwen2.5 7B Instruct
The default starting point for local work on 8–12 GB cards. Strong instruction following and reliable tool-call formatting for its size.
Strengths
- Excellent quality-per-GB
- Reliable structured output
- Very well supported by local runtimes
Limitations
- Shorter context than the Llama 3.x line
- Reasoning drops off on multi-step problems
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
