Mistral 7B is the strongest cheaper option in our database at $0.0220 per 1M blended — about 99% less than Claude Sonnet 5.5. It is also open-weight, so self-hosting is an option.
Can I run Claude Sonnet 5.5 locally?
No. Claude Sonnet 5.5 is a closed, API-only model — the weights are not released, so it cannot be self-hosted.
Why does Claude Sonnet 5.5 charge more for output than input?
Output tokens are generated one at a time and cannot be batched the way a prompt can, so they cost the provider more to serve. Claude Sonnet 5.5 charges 5× more for output, which is why prompt-heavy workloads are far cheaper to run than generation-heavy ones.
