Flux vs OpenRouter
OpenRouter puts hundreds of models on one key, with search, page reading, images and speech built in, and an Auto Router that can choose the model for you. Flux does the core job with a smaller, vetted set of models, picks one for each job, and bills one flat rate per lane.
Where OpenRouter wins: A far bigger catalogue: hundreds of models from many providers.

Going direct means an account with each AI lab, and another for each tool your agent uses. You get each lab's full feature set at its own price, with nobody in the middle. Flux puts every model on one key and one bill, and picks a model for each job.
Where going direct wins: One provider and one contract.
