Scaling multi-agent systems is the next big challenge, harness gains lift model capability
omarsar0 · x · 2026-09-30
AI researcher-communicator Elkhan Yusubov (omarsar0) argues that scaling multi-agent systems is now the big challenge, citing the /goal tool's scale-up: pushing the harness to do more has also pushed model capabilities on long-horizon tasks.
- Key observation: harness capability and model capability aren't independent — stronger harnesses lift long-horizon performance
- Framing: multi-agent scaling is the industry's next frontier problem
