What is PromptFold?
PromptFold is prompt compression API for LLMs that is real-time, lossless and low latency.
It dynamically reduces input token usage while preserving meaning and intent, and automatically optimizes prompts to reduce unnecessary output token count.
PromptFold is fine-tuned for conversational LLM applications like support bots, task assistants, and interactive AI agents.
