What is Claude Fable 5 API relay?

OpenLux runs this layer as a hosted service: https://api.openlux.ai aggregates 452 models available for sale major models behind one OpenAI-compatible endpoint, with a single API key and a single invoice.

Why route through a gateway?
- Verifiable model identifier：claude-fable-5 is listed in the panel's pricing data and can be used as a reference when verifying the request model name and billing.
- Baseline price and multiplier calculated separately：The cost of claude-fable-5 is determined jointly by the baseline unit price and the group multiplier. Confirm the group associated with the current account before integration, then estimate the cost using the formula.
- Cache hits priced separately：The baseline price for cache hits for this model is $1 / 100 ten-thousand tokens. It is listed separately from the baseline input and output prices, making it suitable for separate cost tracking.
- Can be rechecked through the pricing API：The pricing data comes from the panel's own pricing API rather than a manual compilation. You can use the API response to recheck model entries and the current configuration.
- Multiple models available in the same panel：The panel lists a total of 452 models for sale. This article focuses on Claude Fable 5, so the models listed on the page should not be interpreted as a complete model catalog.
