AI API Pricing Comparison (August 2026): Latest Models Side by Side
Updated August 17 API prices for GPT-5.6, Gemini 3.7 Flash, Grok 4.6, DeepSeek V4 peak/off-peak billing, GLM-5.3 status, Kimi K3, Claude, Mistral, and MiniMax.
The August 17 refresh adds Gemini 3.7 Flash and Grok 4.6, applies Googleâs current 2026 introductory Flash price, and replaces DeepSeekâs old flat price with the peak/off-peak schedule that took effect today. GLM-5.3 is also documented, but its pay-as-you-go API and token price are still coming soon, so GLM-5.2 remains the priced Z.AI row.
All USD rows below use standard synchronous rates for cache-miss input and output. Cached-input prices are shown separately. Long-context, Batch, Flex, Fast, regional, and tool charges can change the final bill.
