Pricing References and Billing Caveats

These are the tracked rates, not a live quote. Hosted-provider choice, region, long-context tiers, caching, batch discounts, and temporary promotions can change the actual bill. Open-weight availability does not mean hosted inference is free. Workload examples assume the listed standard input and output rates, with no cache hits or discounts.

No model-specific official reference is recorded for this entry. Confirm the current rates directly with your inference provider.

Effective Cost

In AI IQ's scoring, Step 3.7 Flash's list price is adjusted by a token-usage multiplier of 0.989, giving an effective cost of $1.33 per 1M input + output tokens. That places it #45 of 153 models on the effective-cost ranking (lower is cheaper). Some models spend far more tokens than others on the same task, so effective cost compares what a unit of work really costs. Method details are on the methodology page; see all models on the cost charts and the falling cost of intelligence over time.
