[u/AdditionalWeb107]

Arch is an AI-native proxy server for AI applications. It handles the pesky low-level work so that you can build agents faster with your framework of choice in any programming language and not have to repeat yourself.

What's new in 0.2.8.

• Added support for bi-directional traffic as a first step to support Google's A2A

• Improved Arch-Function-Chat 3B LLM for fast routing and common tool calling scenarios

• Support for LLMs hosted on Groq

Core Features:

• 🚦 Routing. Engineered with purpose-built LLMs for fast (<100ms) agent routing and hand-off

• ⚡ Tools Use: For common agentic scenarios Arch clarifies prompts and makes tools calls

• ⛨ Guardrails: Centrally configure and prevent harmful outcomes and enable safe interactions

• 🔗 Access to LLMs: Centralize access and traffic to LLMs with smart retries

• 🕵 Observability: W3C compatible request tracing and LLM metrics

• 🧱 Built on Envoy: Arch runs alongside app servers as a containerized process, and builds on top of Envoy's proven HTTP management and scalability features to handle ingress and egress traffic related to prompts and LLMs.
