Compare sparse MoE activation routing vs. full dense computation across frontier models.
The Six-Layer Harness
Modern agentic harnesses (Claude Code, Codex, Cursor, Devin, Goose) wrap the model with six functional layers around a continuous gather → act → verify loop. The model reasons; the harness mediates every action.
Open Inter-op Protocols
Two protocols moved from vendor experiments to Linux Foundation standards between 2024 and 2025, defining the tool↔model and agent↔agent integration layers.
Memory Architectures
Memory is now a first-class primitive. Three vendors ship three distinct default architectures (filesystem, identity-database, vector-store); three frameworks compete on the LongMemEval benchmark; Anthropic's "Dreaming" introduces async hippocampal consolidation between sessions.
| Memory System | Type | License | Score | Highlight |
|---|
Multi-Agent Orchestration Frameworks
Four frameworks dominate enterprise multi-agent deployments. The market is shifting from framework-locked solutions to protocol-first designs (Paperclip ACP, A2A) — driven by enterprise demand for portability across vendors.

Agentic Coding: The Killer App
The agentic-coding category posted the highest valuations and ARR growth rates in private AI in early 2026. Computer-use agents — closed and open — crossed the 72.4% human OSWorld baseline.

How the Giants Are Repositioning
Each major software platform is taking a distinct stance on the agent transition — from infrastructure orchestration (AWS) to vertical integration (Microsoft) to consumption-priced agent platforms (Salesforce) to model-vendor compute lock-in (Anthropic + OpenAI).
The Pullback Signals
Not every story is up-and-to-the-right. Three signals show where agent autonomy is hitting cost, reliability, or ROI ceilings — and where humans are coming back into the loop.

Enterprise Architecture Guidelines
Securing operations requires hybrid architectures: centralized APIs for complex deliberation tasks, open-weight systems locally for proprietary workflows. Zero-Trust networks must enforce out-of-band verification (OOBV) on all wire transfers and critical database mutations.
