New · Subagents
The best model is several models.
One workflow, multiple LLMs. Chain Cotera agents together and give each one its own model, tools, and scope. You get better accuracy and lower cost, without paying for a frontier model on every step.

One model for everything is almost never right.
Specialized models, specialized jobs
Claude for nuanced research. Gemini's NanoBanana for creative briefs. Haiku for quick classification. Pick the right tool per step.
No more context drift
Each agent only sees what it needs. Smaller context windows mean fewer wrong tool calls and fewer hallucinated steps.
Cost that actually scales
Two cheap models can outperform one frontier model — at a fraction of the price. Scale to millions of runs without the spend spiral.
Scoped tools, safer agents
Each subagent only has the tools it needs. A refund agent can't accidentally trigger a marketing send. Permission boundaries, by design.
The cost-accuracy chart that changes the math.
Cost per task
Accuracy
Mini with sub-agents matches GPT-5.5 accuracy — at 16× lower cost. Plain Mini gets you to $0.001 per task but drops to 88% accuracy. Adding sub-agents recovers the full 100% for the same $0.001 — versus $0.016 to get there with the frontier model.
