How much does DeepSeek V4 Flash cost?
DeepSeek V4 Flash starts at $0.23 per 1M input tokens through the API Stock API. You pay per use from a single prepaid balance — there is no subscription — and the final price scales with parameters such as resolution or duration.

What happens if a DeepSeek V4 Flash request fails?
API Stock automatically retries the request on a reserve provider. If every provider fails, the charge is refunded to your balance.
