Interpretation, not reported fact. Each point follows from a source listed below — follow the links and judge for yourself.

Enterprise security policies will mandate strict proxy gateways for agentic communications like MCP. (Basis: Cloudflare Gateway introduced dedicated MCP inspection tools to block unapproved model context connections.)
LLM API platforms will face margin compression as low-cost 30B-tier models gain widespread local adoption. (Basis: Meta released Muse Glimmer for consumer hardware, and DeepSeek/Qwen report millions of derivative open-weight deployments.)
RAG architecture best practices will shift toward aggressive pre-LLM query and document filtering. (Basis: VentureBeat reported 6x inference cost reductions by filtering context before it reaches the main model prompt.)
