Codex Service Pricing

All prices are in USD.

🔥 Top up and receive 200% bonus credit

Buy USD $10 or more (supports $10, $20, $30, up to $100) and receive 200% extra bonus credit (for example, top up $20 and receive $60 balance; top up $100 and receive $300).

All prepaid balance is valid for 30 days. If you top up again before expiry, unused old balance is merged with the new balance and the validity extends for 30 days from the new top-up date. Users can also choose a USD $5 trial payment; $5 payments do not receive the 200% bonus.


🎁 Extra free VPN service: users with a single top-up of $20 or more receive one free month of PhotonMark VPN (Individual plan) Personal plan service. You can use the same username and password as this site to log in to the VPN site. After login, you can claim a 1-hour free trial directly; contact us to redeem the 1-month free period.

✨ Fast, stable, high-quality service

Unlike low-price, low-quality, frequently interrupted relay competitors, our pricing reflects high service quality, very stable proxy egress, and fast millisecond-level response.

We connect to the official Codex path, do not silently downgrade or replace models, and do not use slow, fragile reverse-engineered channels, giving long-context and high-frequency work a stable path.

Model Token Pricing

The following are standard billing rates used for balance deduction.🎁 Top-up bonus effect: a single top-up or prepaid purchase of USD $10 or more receives 200% extra bonus credit (for example, top up $20 and receive $60 balance), so for these users the effective cost is about one-third of the standard balance-deduction price.

Models Input (standard) Input (effective) Cached input (standard) Cached input (effective) Output (standard) Output (effective)
gpt-5.3-codex-spark USD $0.175 / 1M USD $0.0583 / 1M USD $0.0175 / 1M USD $0.0058 / 1M USD $1.4 / 1M USD $0.4667 / 1M

Default Billing For Unlisted Models

If the Codex client or OpenAI upstream returns a model not listed in this table, the system keeps the original model name for audit and charges it at the same rate as gpt-5.5-pro until we add that model to the public billing table based on official OpenAI prices and multipliers. This avoids undercharging new or unknown models.

Fast Mode Billing

Fast mode does not multiply upstream token usage and does not change the real input, cached input, or output token counts shown in the dashboard. It only means the request uses a faster service tier and is billed with a higher credit multiplier. Currently gpt-5.5 Fast is calculated at 2.5x the standard cost, and gpt-5.4 Fast is calculated at 2x the standard cost. Other models use standard cost when no official Fast multiplier is available. After OpenAI releases a new Codex model, we verify official prices and multipliers before adding it to the public billing table.

Web Search Billing

If a request uses the OpenAI web search tool, web search calls are billed in addition to model input, cached input, and output tokens. The current rate is 10% of OpenAI's current web search price, USD $0.0010 per web search call, deducted from Pay / Boost balance. Tokens from search results are still billed as input tokens for the selected model.

Image Generation Billing

If a request uses the OpenAI image generation tool, image calls are billed in addition to the main model input, cached input, and output tokens. The current rate is 10% of official OpenAI image generation prices; if the image model, quality, or size cannot be identified, the default estimate uses gpt-image-2, Medium, 1024x1024, which is USD $0.0053 per image.

Real Billing Example

If using gpt-5.4-mini, the price is input USD $0.075 / 1M, cached input USD $0.0075 / 1M, output USD $0.45 / 1M. If a response has input 20,000, cached input 10,000, and output 500, normal input is 10,000; the cost is USD $0.00075 + USD $0.000075 + USD $0.000225 = USD $0.00105, rounded up to USD $0.0011 at 4 decimal places.

If the same usage comes from gpt-5.5 Fast request, first calculate standard cost using gpt-5.5 input, cached input, and output rates, then multiply by the 2.5x Fast multiplier. Token counts still show real usage and are not changed to 2.5x because of Fast.

Note: dashboard balance deduction uses the standard prices on this page. After top-ups of $10 or more receive triple credited balance, the user's effective cash cost is about one-third of the standard deduction.
