DeepSeek open-sourced its Agent execution framework 'DeepSeek Harness,' confirming the shift from model-centric AI competition to system-level competition focused on robust engineering layers. This open-source microkernel framework aims to become a public infrastructure standard for AI agents, enabling modular, deterministic execution of actions beyond models.
This Wire brief sits within Fusion42's coverage of AI Agents and AI Infrastructure.
◆ ◆ The Wire takeaway
You face a new public standard forming beneath AI models that shifts value from model design to execution engineering. Build or integrate with open modular agent frameworks now to avoid becoming a support layer rather than a market leader.
