-Intent Detection and Prompt Matching:

+Intent Matching
+^^^^^^^^^^^^^^^
 
-Arch uses fast Natural Language Inference (NLI) and embedding approaches to first detect the intent of each
-incoming prompt. This intent detection phase analyzes the prompt's content and matches it against predefined
-prompt targets, ensuring that each prompt is forwarded to the most appropriate endpoint. Arch’s intent
-detection framework considers both the name and description of each prompt target, and uses a composite matching
-score between an NLI and cosine similarity to enchance accuracy in forwarding decisions.

 Prompting LLMs
 --------------
-Arch is a single piece of software that is designed to manage both ingress and egress prompt traffic, drawing its
-distributed proxy nature from the robust `Envoy <https://envoyproxy.io>`_. This makes it extremely efficient and capable
-of handling upstream connections to LLMs. If your application is originating code to an API-based LLM, simply use
-the OpenAI client and configure it with Arch. By sending traffic through Arch, you can propagate traces, manage and monitor
-traffic, apply rate limits, and utilize a large set of traffic management capabilities in a centralized way.

 .. Attention::
    When you start Arch, it automatically creates a listener port for egress calls to upstream LLMs. This is based on the
    ``llm_providers`` configuration section in the ``arch_config.yml`` file. Arch binds itself to a local address such as
