Show HN: Sunk Cost – How long until a local LLM rig pays for itself?
TL;DR
Sunk Cost is a tool that estimates the time it takes for a local large language model (LLM) rig to become cost-effective. It calculates local speed based on memory bandwidth and bytes read per token.
✦ Why It Matters
Evaluate your local LLM investment today to determine its potential return on investment.
Key Takeaways
- Calculate your local LLM rig's break-even point using Sunk Cost.
- Adjust assumptions to see how they affect your investment timeline.
- Consider memory bandwidth as a key factor in processing speed.
- Evaluate the cost-effectiveness of local versus cloud-based LLM solutions.
Full Summary
Sunk Cost aims to assist users in determining how long it will take for a local large language model (LLM) rig to become financially viable. By analyzing factors such as memory bandwidth and the number of bytes read per token, the tool estimates local processing speed.
Users can adjust various assumptions to see how changes impact the break-even timeline. The methodology relies on calculating the ratio of memory bandwidth to bytes processed, offering a straightforward way to visualize costs versus benefits.
While specific numerical results were not provided, the implications suggest that understanding these metrics can guide investment decisions in AI infrastructure. This tool is particularly relevant for organizations considering the deployment of LLMs locally versus using cloud services.
