Groq Drops Input Token Pricing, Goes All-In on Output Token Economics

Groq's move to pure output-token metering pushes the cost-per-step of agent loops even lower. This is the pricing model builders needed to make thousands of agentic calls cheap enough for complex workflows.

The Model Context Protocol Spec Reaches v2025-06-18

The spec for the Model Context Protocol (MCP) that lets agents use tools is now stable. This is the foundational standard that will likely govern how your agents connect to APIs and data for the next few years. If you're building agent infrastructure, you need to track this closely.

Beyond the Loop: Agentic Control of Asynchronous Tools

New research explores how agents control distinct, asynchronous tools in a more human-like way. If you're building agents that need to juggle multiple external APIs or tasks at once, this paper outlines some key architectural shifts away from synchronous loops
