How many tokens is that?

Rough heuristic: ~1 token per CJK character, or 4 other characters per token. Use the provider’s tokenizer for exact counts.

Cost vs. performance: the frontier

Cost–performance frontier

Models on the frontier have no alternative with a lower cost and an equal or better score.Adjust your usage to see how the trade-offs change.

DeepSeek V4 Flash Preview$5.04 / month · Score 36.3

On the current frontier. Evaluate it with your actual tasks.

Per million tokens: Input $0.14 · Cache $0.0028 · Output $0.28

Task scores are comparative indices, not accuracy or success rates. The cost axis is logarithmic. Only models with complete pricing are compared.

How is the bill calculated?

Monthly cost = [input tokens × (cache miss rate × input price + cache hit rate × cache price) + output tokens × output price] × daily requests × days ÷ 1,000,000.

Text token costs only. Include billed reasoning tokens in output usage. Excludes tools, search, images, audio, cache writes, tax, subscriptions, tiered prices and batch discounts. Missing prices are never treated as zero. Annual figures multiply the same monthly usage by 12.
