# Software-Level Inference Efficiency

Decoding and serving optimizations keep cutting the cost of running a given model without retraining it, steadily lowering the compute barrier to deploying frontier-class open-weight models and partly neutralizing hardware access limits.

## Recent evidence

- [confirms] Inference-cost pressure produces both a serving paper and a prompt-stripping trend (2026-07-03): A serving-side KV-cache compression paper plus a developer prompt-stripping trend both cut per-query cost without retraining the underlying model.
- [confirms] The cheapest capability gain now is spending fewer tokens (2026-07-03): KV-cache compression for reasoning models cuts serving memory without retraining, a software-level optimization lowering the cost of running a given model.
