MiniMax has opened its Sora rival, H3, to home GPUs, but with one significant catch. The move allows individual users to run the AI model on their own hardware, expanding access beyond cloud-based platforms. However, the specific limitation or restriction that constitutes the "big catch" is not detailed in the provided text. The article body instead focuses on a separate topic: negotiating fractional executive contracts. It advises treating a first draft as a starting point, not an offer, and highlights common issues such as vague scopes, undefined hours, and retainers without minimum terms. The text notes that a Series A company might not need a full-time CFO at $250,000 plus equity, and mentions platforms like Paro, Chief, and Toptal. It recommends writing a specific scope with deliverables, putting a number of hours in writing, and asking for a minimum engagement of three months, with six being better for CFO-level work.
