What is Grok 4.5 API proxy?
An API gateway sits between your code and the model vendors: you send OpenAI-format requests, and it handles routing, protocol translation, and metering.
Teams calling the grok-4.5 API directly tend to hit the same three walls: one SDK per vendor, one invoice per vendor, and rate limits that differ everywhere.
OpenLux runs this layer as a hosted service: OpenLux official site 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?
- Grok 4.5 is available：The list of models available for sale from the pricing API includes grok-4.5, which is marked as a text model.
- Benchmark pricing can be verified：The benchmark prices for grok-4.5 input, output, and cache hits can all be verified through the panel pricing API, in USD per 1 million tokens.
- Group multipliers affect billing：The actual price is not a fixed benchmark price; it is the benchmark price multiplied by the multiplier for the user's group. Confirm the group associated with the current account before making calls.
- Multiple models are available on the same panel：The platform lists a total of 452 models for sale. The provided list includes only the 150 models with the highest call volumes; the 302 models not listed should not be considered unsupported.
