You can reduce token costs by applying semantic caching and tiered prompt compression to large-context prompts. This approach reuses previous results and minimizes token usage in long-running LLM sessions while preserving answer quality.

Semantic caching for LLM prompts persists embeddings and prompt fragments to reuse previous results. By storing this data, the system avoids recomputing identical or highly similar queries, which lowers token usage and latency in repeated workflows.

You need prompt compression when handling large-context prompts over 50K tokens or repeated queries with similar prompts. It applies tiered compression strategies to minimize tokens while maintaining controllable accuracy across long-running sessions.

Yes, you can manage memory placement strategies for long-running LLM conversations by using memory tiering. This approach balances latency and relevance by organizing data across working, FIFO, and archival memory tiers.

Yes, prompt caching works effectively with repeated queries and similar prompts. It uses pre-prompt compression and post-response caching integration points to streamline workflows, making it ideal for large-context code assistants or interview scenarios.

The main limitation of prompt compression for high-context conversations is the trade-off between minimizing tokens and maintaining accuracy. While compression tiers are controllable, aggressive reduction may impact the relevance of essential information.
