How to choose between gpt-5 and llama-3.3-70b-versatile
- Quality first. Cost only matters if both models clear your quality bar. Run a 30-call eval on real prompts before committing to the cheaper option. If quality is unequal, the price difference is a distraction.
- Match price to call shape. gpt-5 costs
$5.00 in / $20.00 out. llama-3.3-70b-versatile costs $0.59 in / $0.79 out. Workloads that are completion-heavy weigh output prices more.
- Caching changes the math. gpt-5 cache-read is $0.50 (10× off input). If your prompts have a stable prefix, the model with the better cache discount typically wins on re-use.
- Latency may matter more than dollars. Some providers are 5-10× faster at the same price tier. If you're below a few thousand calls/day, latency UX usually beats price.
