Why current LLM costs are not sustainable
AI has a cost problem. The solution that will emerge will be simpler than we expect.
A lot of companies are getting bitten by high AI costs. Uber burned through the entire yearβs AI budget in just 4 months and Microsoft, Salesforce and Github are taking steps to reduce AI spend by employees.
On the other hand, AI is making many programming tasks very easy and also keeps helping in other domains like data interpretation, making beautiful slides and designing apps and websites. Currently, big AI labs have what we call frontier models and those models perform exceptionally well for a wide variety of tasks. Frontier AI labs are doing research and hosting both on their own and hence, the costs of those models are the highest. GPT 5.5, for example, costs $5 per million input tokens and $30 per million output tokens. This is currently the costliest model available as per OpenRouter . To give an example, just doing Typescript type fixes with this model across 50 files cost me $54 this afternoon.
Model performance plateau, Open weight model releases, Chip and model improvements, Zero switching costs and local models are the reasons the AI labs might not be able to sustain the high price that they are asking right now.
We are seeing improvements with each model release these days but itβs clear that the improvements are getting smaller and smaller. Unless a completely new breakthrough is invented, current learning and inference capabilities can only scale so much. There is a problem of training data as well. Most AI labs have likely ingested everything available in digital and print media for the model training. Improving the training dataset is going to prove very difficult.
This means the continuing trend of hikes in model price due to better performance is not going to be easy. We saw evidence of it where Claude Opus 4.8 costs the same as Claude Opus 4.7. Once models stop improving big time and the training data and methods are similar, the model prices will likely drop due to competition.
