The developer of Mnemara, a tool designed to manage context windows for LLMs, found it was ineffective for cloud-based models like Claude. Mnemara's strategy of aggressively curating context to fit smaller windows works well for local models where context size is a hard limit. However, for cloud models with large context windows and prompt caching, Mnemara's eviction techniques actually increase costs by invalidating the cache, leading to more expensive API calls. AI
