How Much Are You Spending on AI Tools Each Month?

Many AI tool users find their monthly expenses creeping beyond expectations without realizing it. Common spending categories include:

AI Subscriptions: ChatGPT Plus ($20/month), Claude Pro ($20/month), Gemini Advanced, etc.
API Call Fees: OpenAI API, Anthropic API, etc. pay-as-you-go
Proxy Service Fees: Top-ups or monthly fees for API access via proxies
VPN / Connectivity Tool Fees: Connection costs for cross-border AI service access
Automation Tool Fees: n8n Cloud, Make, and similar automation platform subscriptions

It’s not uncommon for these to add up to tens or even over a hundred dollars per month.

Five Cost-Saving Strategies

Strategy 1: Pay-as-You-Go API vs. Monthly Subscription

If you primarily use APIs rather than chat interfaces, pay-as-you-go is typically cheaper than a monthly subscription.

ChatGPT Plus ($20/month) suits daily chat interface users
If you’re mainly developing and calling models via API, pay-as-you-go can be cheaper if usage is low
You can mix both: light API usage, using the web interface when needed

Note: Specific pricing is subject to official announcements; API pricing varies by model.

Strategy 2: Consider an API Proxy

If your API usage is consistent, a proxy’s top-up plans may be more economical than the official API. But note:

Risk Note: Proxies carry stability, privacy, and service continuity risks. Do not send sensitive data through proxies, and do not rely on them for production environments.

Strategy 3: Leverage Free Tiers & Credits

Many AI services offer free tiers or trial credits:

ChatGPT Free: Basic features available, suitable for light use
Claude Free: Daily usage limits, but sufficient for everyday tasks
Google AI Studio: Free Gemini API testing credits
Various proxies often offer new user bonuses (check specifics yourself)

Strategy 4: Avoid Duplicate Subscriptions

Are you subscribing to multiple overlapping AI services? For example:

ChatGPT Plus + Claude Pro + Gemini Advanced: Core functionality overlaps significantly
We recommend keeping the 1-2 you use most and switching others to pay-as-you-go or free tiers

Strategy 5: Use Open-Source or Self-Hosted Options

For advanced users:

If you have local hardware, consider open-source models (Llama, Qwen, etc.)
Self-hosting eliminates API fees, but requires hardware investment and maintenance time
Suitable for scenarios with high privacy requirements and technical capability

Practical Saving Combinations

Light Users (Monthly Budget Under ¥100)

Use ChatGPT / Claude free tiers
Official API pay-as-you-go for low API needs
No VPN needed

Moderate Users (Monthly Budget ¥100-300)

Keep 1 monthly subscription (your most-used service)
Use a proxy top-up plan for API needs
Pick an affordable VPN if cross-border access is needed

Use the Cost Calculator to model different combinations’ monthly spending.

Heavy Users (Monthly Budget ¥300+)

Evaluate whether you truly need multiple subscriptions
Consider whether a larger proxy top-up plan is more economical
Verify that your VPN/connectivity plan is the best value
Check that automation tool plans match your usage
