Tokens too cheap to meter
summary
The cost of machine learning intelligence is plummeting due to simultaneous improvements in hardware efficiency, model architectures, and inference software. This rapid decline suggests that AI will soon transition from a standalone product to a ubiquitous infrastructure layer integrated into all computing. Consequently, the primary constraints on AI adoption will shift from the cost of tokens to the quality and accessibility of the models.
key points
- Hardware and software efficiencies are compounding, with GPU power efficiency doubling every two years and inference engines like vLLM providing significant year-over-year gains. This reduces the overall energy and monetary cost per task.
- Architectural shifts, such as Mixture-of-Experts and Mamba hybrids, are drastically lowering memory requirements and compute needs for the same level of intelligence. This enables high-quality models to run on commodity local hardware rather than relying solely on expensive hosted services.
- As intelligence becomes 'too cheap to meter,' it will be integrated directly into basic computing tools, such as build schedulers or shell commands. This will trigger a Jevons Paradox where increased efficiency leads to massive growth in total AI usage and a shift in software value from algorithms to operations and security.

discussion positive
consensus
Commenters generally agree that while LLM inference costs will continue to drop significantly, they are unlikely to become cheaper than highly optimized, deterministic tools like grep. The prevailing view is that software efficiency has physical and logical lower bounds, such as I/O bottlenecks, which apply to both LLMs and traditional utilities. Most believe that LLMs will asymptotically approach these costs rather than surpassing them through perpetual exponential progress.
top insight
The discussion suggests that the future of LLM cost reduction lies in 'ASIC-burning' stable core logic—the 80-90% of parameters representing universal knowledge—while maintaining dynamic layers for tuning. This hybrid approach would allow for massive price drops by freezing the most computationally expensive, unchanging parts of a model into hardware, creating a value proposition based on the stability of knowledge rather than just raw architectural efficiency.
