“Open models can do 90% of agentic work at a twentieth of the cost of a frontier LLM: Gartner”

Key points

• Gartner says open-weight models handle 90% of routine agentic steps for a quarter of the price.
• Analysts expect open-weight models to run hundreds of routine steps per frontier-needed step.
• Cost comparison: open models cost a quarter of the cheapest closed model at same score.
• Frontier models may still be needed for research, effectively serving as capital expense.
• By 2030, Gartner predicts 90% of enterprise agentic steps will run on open-weight models.
