Frequently Asked
Is the cheapest model always the right choice?
Only if it meets your accuracy bar for the specific task — test cheaper options against your actual use case before committing, rather than choosing purely on price.
Are open-weight models cheaper than closed models?
Often yes for API-style usage, particularly at high volume, though you should also factor in any infrastructure cost if you're self-hosting rather than using a managed API.
How do I estimate my actual monthly cost?
See our Token Calculator and Calculators page for tools to estimate cost based on your expected usage.
Where can I find a free option entirely?
See our Free LLM API roundup for options with a genuinely free tier or fully free access.
