Manus Flex lets users connect their own API keys to the Manus workspace

Manus is launching Manus Flex, a module that lets users power Manus agents with their own API key from a supported inference provider. Model inference is billed directly by that provider, while other services used in Manus tasks still consume Manus credits. OpenRouter, Fireworks, and Modal are announced as initial inference partners for the Flex Inference Partner Program.
