General intelligence is not a task-specific quality guarantee. Test shortlisted models on your own examples. Source reviewed — exact offer checked on its provider page. Needs review — missing, stale or conflicting evidence; excluded from default recommendations. Estimates cover input/cache-read/output tokens only. Cache writes, storage, tools, search fees, taxes and unconfigured billing conditions are additional. Include billed reasoning tokens in your output estimate.

Model Cost Comparison · Built by Lazige · Methodology
How we calculate cost
Monthly estimate = (input tokens × input $/MTok) + (cached tokens × cached $/MTok when published) + (output tokens × output $/MTok), scaled to your message volume. See the methodology for validation sources and update cadence.

“Start with a preset that matches product shape, then adjust volume after a week of real traffic.”
“Compare supported cache scenarios for RAG and agents, then validate the assumptions against actual usage.”
“Use the ranked list to shortlist two to three models, then validate quality on your eval set.”
“Re-run when traffic grows or vendors publish new tiers; check the dataset validation date and official rates.”
