AIFast Link: pay-as-you-go funding and monthly plans
Choose between usage-based funding and a 30-day GPT or Claude API plan. Compare the payment currency, daily allowance, eligible group and actual task costs before buying.
AIFast Credit is a platform usage unit, not cash. Check the payment amount and credited balance at checkout. Current prices and supported methods appear on the console and checkout page.
GPT and Claude monthly plans: daily limits and billing
Gemini models use a separate group in the current Link catalog. Do not assume a GPT or Claude plan covers Gemini; confirm eligible groups and billing preferences before purchase.
Choose a billing option in three steps
- Check the model ID, endpoint and API Key group in the model selection guide. A model listed in the catalog is not necessarily included in your plan.
- Enter your actual usage days, daily peaks and wallet overages in the monthly-plan cost comparison. Compare the same completed work: a monthly plan is not necessarily cheaper.
- Before paying, confirm the current order price, eligible groups, reset time, wallet fallback and cancellation terms. Start with pay-as-you-go when usage is uncertain; do not treat unused daily allowance as a refundable balance.
Checked on 2026-11-04 against the AIFast Link subscription page. These are dated plan listings, not permanent price offers. Plans last 30 days and reset their allowance daily. Weekly figures are daily allowance × 7, not a separate weekly pool.

* The dollar sign above follows the console’s usage-allowance display. It represents API usage allowance, not cash or a fixed token count. Refund eligibility is a separate policy to confirm before buying. Request costs depend on the selected model and group. Group names identify the plan scope; check the live model list for access to a specific model ID.
When does a monthly plan make sense?
Compare the cost of completing your own tasks across the days you actually use the service. A 30-day plan with a daily limit is not a balance you can spend all at once. For irregular workloads, estimate pay-as-you-go costs first. A Link monthly plan is an API usage plan, not a ChatGPT or Claude consumer-app subscription.
Worked example: 5, 20 or 30 active days
Illustrative inputs only, not a Link offer: a CNY 200 plan, 20 Credit per day, and tasks consuming 10 Credit per active day in the eligible plan group. Assume the same tasks cost CNY 12 per day on pay-as-you-go. There are no overages in this example.
| Active days | Pay-as-you-go (CNY) | Plan (CNY) |
|---|---|---|
| 5 | 60 | 200 |
| 20 | 240 | 200 |
| 30 | 360 | 200 |
The plan is not automatically cheaper: unused days still count toward its validity period. Compare the same completed work and include any wallet overages. This example excludes refunds and assumes no carryover of daily allowances.
Read the result: 17 active days is this example’s break-even point
At 5 days, pay-as-you-go costs CNY 60 versus CNY 200 for the plan. At 20 days the totals are CNY 240 and CNY 200; at 30 days they are CNY 360 and CNY 200. The break-even calculation is 200 ÷ 12 ≈ 16.7 active days. This is specific to the inputs above, not a recommendation that every plan is cheaper after 17 days.
Same monthly usage, different daily peaks
Keep the illustrative CNY 200 plan and 20 Credit daily allowance. Spread 200 Credit across 20 days at 10 Credit per day: the plan covers it for CNY 200 versus CNY 240 on pay-as-you-go. Concentrate the same 200 Credit into two days at 100 Credit per day: 80 Credit per day exceeds the daily allowance. Assuming wallet fallback is enabled and the effective overage price is CNY 1.20 per Credit, the plan-plus-wallet total is:
200 + 2 × (100 − 20) × 1.20 = ¥392 · Pay-as-you-go for the same work: ¥240
Without wallet fallback, this concentrated workload is not covered by the plan: do not describe it as a CNY 200 solution. For uneven workloads, calculate the excess for each active day and add it; unused allowance from another day cannot cover a peak. The CNY 1.20 conversion is a hypothetical input, not a Link exchange rate or a current offer.
Method updated on 11 October 2026. These examples use the same calculation function as the cost tool; the plan listing above was checked separately on 2026-11-04.
Compare your own usage days and daily overages
Before buying: overages, expiry and cancellation
Reaching the daily allowance does not always stop requests. On 8 October 2026, the Claude Advanced plan allowed wallet fallback after its allowance was exhausted; whether a request uses wallet funds also depends on your billing preference. Confirm both the plan setting and your preference before use. This check does not establish the setting for every plan, and no exhaustion or debit test was performed.
The inspected plan cards do not specify automatic renewal, unused-allowance rollover, refunds or cancellation terms. Confirm these with support before payment. Daily limits cannot be spent as a single monthly balance.
GPT-6.1 Sol: a dated, like-for-like price example
Checked on 8 November 2026. Link model plaza: gpt-6.1-sol, Codex discount group (x0.7), recharge-converted view. The displayed input and output rates already include the group multiplier; do not multiply by 0.7 again.
| Price basis | Input | Output |
|---|---|---|
| OpenAI published USD rate | $2.00 | $10.00 |
| OpenAI converted at an illustrative USD 1 = CNY 7 | CNY 14.00 | CNY 70.00 |
| Link recharge-converted display, specified group | CNY 1.05 | CNY 5.25 |
Under these assumptions, the displayed price difference is 1 − 1.05 / 14 = 92.5% for input and 1 − 5.25 / 70 = 92.5% for output. The exchange rate is an illustration, not a live quote. Link usage allowance is not USD cash.
This is a comparison of published prices, not a paid-call receipt or proof of model identity, equivalent quality or availability. It is not a site-wide discount. Cache, long context, priority modes, tools, taxes, retries and other groups can change the total. Monthly plans are separate; GPT/Claude plans do not include the separate Gemini group.
Verify the sources: OpenAI model pricing · Link live model plaza
On Link, search for gpt-6.1-sol, select the Codex discount group with multiplier x0.7, then Recharge conversion and /1M. Check the current group and final bill before buying.
What does a complete task cost at these rates?
Illustration: 100,000 uncached input tokens and 20,000 billed output tokens give 100,000 / 1,000,000 × 1.05 + 20,000 / 1,000,000 × 5.25 = CNY 0.21. These are assumed token counts, not a measured workload. Count all billed output, not only the visible answer, and add any cache writes, long-context surcharges, priority tiers, tool fees or retries separately.
Estimate a complete task with your own prices and token counts
Match the plan to the client before paying
A billing plan and an API protocol are separate choices. Confirm the client endpoint and your key's group before using a cost estimate to choose a plan.
- Claude Code: Anthropic base URL and authentication. Check Messages support and the plan's Claude group.
- Codex: custom provider and Responses API. A successful Chat Completions request does not establish Responses support.
- Gemini: model IDs and protocol selection. Calculate the separate Gemini group independently of GPT or Claude plans.
Compare actual usage days and daily overages, then verify the current plan terms at checkout. The calculator uses your inputs; it does not quote live account prices.
Pay as you go: separate payment from API usage
On 8 October 2026, the wallet displayed a ¥7.50 payment for $10 in site usage allowance, with WeChat Pay available. This is a dated display example, not a USD exchange rate or a fixed token price. Discounts and payment options can change; check the final order before paying.
Monthly plan cards displayed Alipay / WeChat Pay. This check did not establish card, USDC or USDT support, so this guide does not advertise those methods.
Billing questions
Which groups do AIFast Link GPT monthly plans cover?
The subscription page checked on 2026-11-04 lists GPT Starter: Codex special-price group; GPT Basic: Codex dedicated group; GPT Plus: Codex dedicated group; GPT Advanced: Codex stable group. A plan covers its specified group, not every GPT model or all groups. Confirm the current order and your API Key group before paying.
Does a GPT or Claude monthly plan include Gemini API usage?
Do not assume it does. AIFast Link lists Gemini in a separate group, while GPT and Claude plans specify Codex or Claude groups. Check Gemini access and billing separately; a model catalog listing is not a plan entitlement.
What is an AIFast Credit?
A platform usage unit for API allowance, not cash or legal tender. The console may use a dollar sign to display it; the amount charged by the payment provider is a separate value.
Is a monthly plan unlimited?
No. Current GPT and Claude plans last 30 days, reset daily and apply to their specified group. Weekly figures are daily allowance multiplied by seven, not an additional allowance.
Are these ChatGPT or Claude memberships?
No. These are AIFast Link API usage plans. They do not include a subscription to the model vendors’ consumer apps.
Can I cancel or obtain a refund?
The inspected plan cards do not state renewal, cancellation or refund terms. Confirm these with support before payment; do not assume automatic renewal or refunds.
