An angel investor is evaluating two new startup options related to Large Language Model (LLM) engines that have different capabilities and annual return trajectories. Option A (Engine A) can be trained using current state-of-the-art LLM models. It offers a decent return of $480,000 + CCC per year, which increases by 3% annually after the first year. Option B (Engine B) requires some initial learning from user interaction, resulting in annual returns staying low at $80,000 for the first 5 years.
