Natural Language Processing is Artificial Intelligence that enables computers to analyze and understand human language. Pryon’s AI is trained to perform read, organize and search in ways that previously required humans. This powerful capability is used in every interaction, both to understand a request and to retrieve the accurate response. The success of any NLP project is directly correlated to the sophistication of the underlying natural language technologies used. To make your content ready for use in chatbots, search, automations, etc. – it must be broken into specific pieces so a user can get the exact answer, result or snippet needed. This can be done manually as when a specialist breaks information into intents and entities. Pryon creates a dynamic model of your content for automatically identifying and attaching rich metadata to each piece of information. When you need to add, change or remove content this model is regenerated with a click.

Entry Point AI is the modern AI optimization platform for proprietary and open source language models. Manage prompts, fine-tunes, and evals all in one place. When you reach the limits of prompt engineering, it’s time to fine-tune a model, and we make it easy. Fine-tuning is showing a model how to behave, not telling. It works together with prompt engineering and retrieval-augmented generation (RAG) to leverage the full potential of AI models. Fine-tuning can help you to get better quality from your prompts. Think of it like an upgrade to few-shot learning that bakes the examples into the model itself. For simpler tasks, you can train a lighter model to perform at or above the level of a higher-quality model, greatly reducing latency and cost. Train your model not to respond in certain ways to users, for safety, to protect your brand, and to get the formatting right. Cover edge cases and steer model behavior by adding examples to your dataset.

LMCache

LMCache is an open source Knowledge Delivery Network (KDN) designed as a caching layer for large language model serving that accelerates inference by reusing KV (key-value) caches across repeated or overlapping computations. It enables fast prompt caching, allowing LLMs to “prefill” recurring text only once and then reuse those stored KV caches, even in non-prefix positions, across multiple serving instances. This approach reduces time to first token, saves GPU cycles, and increases throughput in scenarios such as multi-round question answering or retrieval augmented generation. LMCache supports KV cache offloading (moving cache from GPU to CPU or disk), cache sharing across instances, and disaggregated prefill, which separates the prefill and decoding phases for resource efficiency. It is compatible with inference engines like vLLM and TGI and supports compressed storage, blending techniques to merge caches, and multiple backend storage options.
