Task fit and model switching guide
Derived from official positioning and current ComputeUnion provider and pricing data.
Discount vs official API
Input-price difference for the same model; negative values are above official price.
Price composition
Input and output remain paired within each provider quote.
Capability radar
Task-fit levels derived from official positioning, not an independent benchmark.
Channel cost and evidence map
X-axis is observed example monthly cost; Y-axis is price-evidence strength.
