Kingy topic graph · Model economics and migrations
Price the workload. Plan the migration.
Use observed pricing evidence, workload-level comparisons and implementation guides to understand model cost—and move away from retiring APIs without treating a list price as the whole decision.
Evidence boundary: prices, availability and deprecation dates remain owned by their source records. This hub organizes Kingy coverage and does not copy mutable claims into a new truth store.
Start here
Anchor the decision in observed evidence
Begin with Kingy’s price-stability ledger, then inspect the collection method before using any historical observation in a purchasing or migration decision.
AI model list prices barely move
Explore the editorial price-stability ledger and its provider/model observations.
Open the price-stability ledgerHow the price record is built
Understand archived captures, bounded change windows and the evidence limits behind each record.

Separate a price observation from a workload decision
The ledger records visible pricing changes. It does not by itself measure output quality, latency, cache behavior or the number of attempts required to finish a job.
31,946 observations of model-price stability
Inspect the large-scale audit behind the stability finding and the limits of what those observations establish.

Model the workload, not the headline rate
Use bounded comparisons that make workload assumptions visible and keep provider coverage, discounts and operational limits in view.
OpenAI vs Anthropic API pricing
Compare representative workloads and the conditions that can reverse a simple token-price ranking.
Open the workload comparisonAI inference providers compared
Compare model coverage, pricing structure, speed, limits, privacy and availability across inference providers.
Open the provider comparisonRecalculate before buying
Vendor prices and discount rules can change. Treat each comparison as a decision framework, then verify the current primary pricing pages.
Migration guides
Move the contract, not only the model name
A safe migration preserves behavior, tests, permissions and rollback—not merely API compatibility.
Assistants to Responses and Conversations
Plan state, thread backfill, tool behavior and verification as the Assistants API retires.
Open the migration guideAgent Builder to a durable workflow
Choose between Agents SDK and workspace agents while keeping workflow artifacts portable.
Open the agent migration guideGPT Image 1 to GPT-Image-2
Re-baseline image behavior, parameters, policy and rollback instead of changing only the model ID.

Resolve stable identities before comparing mutable facts
These profiles provide canonical product identities. Their origin releases exist, but their public Product Facts endpoints are currently unavailable, so this projection makes no pricing or capability claim from them.

Discovery is not a current-price guarantee
Every destination retains its own date, source and testing limits. Verify current vendor terms before procurement or migration, and require workload-specific tests before changing production systems.
This editorial hub is a curated discovery layer. Each destination retains its own evidence, testing and disclosure boundary.
