Prices are not ranked on this page. For a job, use the sourced quote (separate input and output rows, Depot Pick unchanged): llm-tracing, evals, cost-monitoring, experiment-tracking.
Alternatives are other catalog providers that share a JTBD as pick or runner-up. If fewer than three exist, same-category active providers fill the list and are labeled same_category. Overall deltas are catalog scores. kind=curated_estimate is not a lab measurement. Pricing rows are sourced or explicitly null. Do not parse pricingNotes. A single normalized USD figure is set only for a provider with exactly one token row.
