Glean CEO on model routing: frontier model costs and open-weight popularity push enterprises toward automatic model selection

Frontier Model Cost and Open-Weights Popularity is Driving Demand for Model Routing

Glean CEO Arvind Jain says model routing is gaining enterprise traction mostly because of cost. Per-token pricing for Opus or the latest GPT models is 2-4x higher than previous generations, and users run longer tasks on them, pushing per-user spend up 10-20x year-over-year. Glean's automatic mode picks a model per task—or skips an LLM entirely. Engineering lead Tony Gentilcore claims Glean averages $0.45 per task vs. $1.84 for Claude Code, a 4x gap. Glean hit $300M ARR, tripling in 15 months. The post does not detail Waldo's routing mechanics.

Why it matters: Glean's CEO shares first-party cost data (10-20x annual per-user spend increase) with concrete routing mechanics — H and K are solid. But it's a product-focused interview, not an industry report, so R is weak. Lands at the featured threshold of 72.
