Output tokens can have the biggest impact on your bill because a model’s answer is usually longer than its prompt. When you compare pricing, it’s worth checking the output rate first rather than focusing only on input costs.
For comparison, the lowest-priced models I currently track are Qwen 3.7 Flash at $0.13 per million output tokens and DeepSeek V4 Flash at $0.64.
I update the full pricing comparison for tracked models daily in the AI cost calculator, with rates applied to real-world tasks. Prices come from OpenRouter’s public API and may differ from promotions offered directly by providers.
