7 Ways Backend Engineers Are Mistakenly Treating Wasm-Based Agent Sandboxing as a Sufficient Per-Tenant Execution Isolation Primitive for Multi-Tenant Agentic Pipelines in 2026

WebAssembly has had an extraordinary run. What started as a browser performance trick has matured, through the Wasm 3.0 specification and the WASI Component Model, into a genuinely compelling server-side runtime primitive. It is fast, portable, and ships with a capability-based security model that looks, on paper, like exactly

7 Ways Backend Engineers Are Mistakenly Treating AutoGen 0.4's Actor-Based Agent Runtime as a Safe Per-Tenant Execution Sandbox

Microsoft's AutoGen 0.4 was a landmark architectural shift. It moved away from the conversation-centric model of earlier AutoGen versions and introduced a proper actor-based agent runtime, inspired by the actor model popularized by frameworks like Erlang and Akka. Agents became first-class, message-passing entities. The AgentRuntime became the

How the March 2026 Model Release Wave Broke Per-Tenant Model Selection Logic (and the Dynamic Capability Fingerprinting Architecture You Need to Survive the Next One)

In the span of roughly three weeks this past March 2026, the AI industry did something it had never quite managed before: it released more than a dozen significant large language models simultaneously. Not sequentially. Not in a polite, one-per-month cadence that backend teams could absorb. All at once, in
