A 4B model beats Jev in hybrid agent setup that runs 13x faster at 56% cost
Sentdex · x · 2026-09-22
Sentdex shares experiments combining GLM 5.3 Flash with a small model in a hybrid agent setup on the Halite strategy game.
- Prior result: the hybrid (LLM handles strategic judgment, Jev handles ship-by-ship execution) ran 13x faster, cost 56% of pure LLM API spend, and slightly outperformed; GLM 5.3 Flash alone beats Jev alone 82% of the time.
- New test: swapping in OpenJev (4B) handily defeats Jev in this toy scenario, making him curious about Jev's actual model size.
- He frames this as early exploration of using small models to augment LLM agents, with more room to cut cost and boost performance.
