AI SaaS faces hidden costs from multi-turn context bloat

By PulseAugur Editorial · [1 sources] ·

AI SaaS providers often underestimate the true cost of multi-turn conversations, leading to margin bleed. The issue stems from LLMs being stateless, requiring the retransmission of entire conversation histories with each new turn, exponentially increasing token usage. For instance, a 20-turn session can consume hundreds of thousands of input tokens, far exceeding the cost of a single API call. To combat this, developers can implement engineering fixes such as optimizing prompt caching by structuring requests deterministically and employing a tiered routing system that directs simpler tasks to cheaper models while reserving premium models for complex reasoning.
