Inference speed hits billion tokens per minute on single GPU

Modal released Quail, an inference engine that processes over one billion tokens per minute on a single H100 GPU—over 10 times faster than vLLM on identical hardware. The system combines a query planner with a specialized inference layer to optimize token throughput. At $0.06 per billion tokens on Modal's platform, this represents a significant cost reduction for high-volume inference workloads and opens new possibilities for real-time applications.

Why it matters

💻 Developer · Token throughput is now the metric that matters. If you're deploying inference at scale, Quail-class speeds change your architecture fundamentally. You can now serve latency-tolerant workloads (batch processing, async agents) at costs that make economic sense for margin-constrained businesses.

📦 Product · Cost per inference just dropped by an order of magnitude for batch workloads. Features that were too expensive to run on every user input (reasoning, chain-of-thought, multi-step planning) are now viable. Rethink what you can afford to do with AI.

🎨 Design · Faster inference means richer interactions. But speed alone doesn't fix UX. Use the margin to add explanations, reasoning transparency, or multi-turn context without worrying about cost explosion.

📈 Business · Margin expansion on inference-heavy products. If you're already profitable on LLM workloads, this is a straight profitability increase. If you're unprofitable because inference costs are too high, this changes the equation. Revisit your pricing and feature set.

🤔 Just Curious · This is engineering excellence in motion. Query planning + inference optimization is not a fundamental breakthrough, but the execution is. It shows that inference economics are not yet mature—there's still 10x on the table for teams willing to optimize the full stack.
