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.
Publisher-reported pricing notes
- Canonical prices are standard rates; a temporary 50% discount lasts through October 22, 2026 UTC.
Official release and model references
These references document the model and its release; not every reference is a pricing table. Confirm the applicable endpoint and billing tier with your inference provider before purchase.

Effective Cost
In AI IQ's scoring, Solar Mini 4's list price is adjusted by a token-usage multiplier of 2.146 (measured from real benchmark runs), giving an effective cost of $1.07 per 1M input + output tokens. That places it #39 of 156 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.
