Why Choose Sora 2 API Proxy Service? Save 90% with Per-Request Billing vs Per-Second Billing

Core Insight: OpenAI Sora 2's official API uses per-second billing ($0.10-$0.50/sec), while API.yi and other proxy services use per-request billing ($0.15-$0.20/request). Cost comparison shows: in 99% of use cases, proxy services' per-request billing model saves users 85%-95% in costs, while providing more resolution and duration options without requiring invitation codes.

💰 Fundamental Differences Between Two Billing Models

OpenAI Official: The "Hidden Costs" of Per-Second Billing

Official Pricing Strategy:

OpenAI Sora 2 API uses per-video-duration (seconds) billing:

Resolution	Price/sec	10s Video Cost	15s Video Cost
720p	$0.10	$1.00	$1.50
1024p	$0.20	$2.00	$3.00
1792p Pro	$0.50	$5.00	$7.50

Problem Analysis:

❌ High Cumulative Cost: $1-$5 for just 10 seconds
❌ Hard to Budget: Difficult to precisely control video duration
❌ High Resolution Price Surge: 1792p is 5x the price of 720p
❌ Payment Barrier: Requires international credit card and USD account

Why So Cheap?

Proxy services purchase API quotas in bulk, getting wholesale prices
Per-request billing eliminates "per-second accumulation" hidden costs
Multi-user sharing of infrastructure costs

Advantage 2: Payment Convenience – Direct CNY Payment

Official API Payment Barriers:

❌ Requires international credit card (Visa/Mastercard)
❌ Requires USD account
❌ Potential exchange rate losses and fees
❌ Some regional bank cards may be rejected

Proxy Service Payment Advantages:

✅ Supports Alipay and WeChat Pay
✅ Direct CNY settlement
✅ No exchange rate risk
✅ Instant top-up and use, no waiting

Advantage 3: No Invitation Code – Register and Use

Official API Access Restrictions:

❌ Need to join waitlist for invitation code
❌ Wait time uncertain (may be weeks to months)
❌ New accounts Tier 1 limits strict (only 5 requests per minute)

Proxy Service Access Advantages:

✅ No invitation code needed, use upon registration
✅ Generate videos immediately, no waiting
✅ No Tier limits, new users can make high-frequency calls
✅ Free trial credits provided

Advantage 4: Flexible Resolution Options – Same Price Multiple Choices

Official API Resolution Pricing:

720p: $0.10/sec
1024p: $0.20/sec (2x more expensive)
1792p: $0.50/sec (5x more expensive)

Proxy Service Resolution Pricing:

704×1280 (Portrait Standard): $0.15/request
1024×1792 (Portrait HD): $0.15/request (same price!)
1280×704 (Landscape Standard): $0.15/request
1792×1024 (Landscape HD): $0.15/request (same price!)

Key Finding: Proxy service's HD version (1024p) and standard version (720p) are the same price, while official HD is 2x more expensive!

Advantage 5: Domestic Network Direct Connection – Faster Speed

Official API Network Issues:

⚠️ Servers overseas, domestic access may be slow
⚠️ May require special network environment
⚠️ Image uploads (image-to-video) may timeout

Proxy Service Network Advantages:

✅ Domestic server deployment, low latency
✅ No special network configuration needed
✅ Fast upload speed, high generation efficiency
✅ CDN acceleration for video downloads

🔍 Deep Analysis: Per-Request vs Per-Second Billing

Why Is Per-Request Billing More Suitable for Most Users?

1. Real-World Video Duration Scenarios

According to social media platform data:

TikTok: Average video duration 10-15 seconds
Xiaohongshu: Average video duration 8-12 seconds
YouTube Shorts: Average video duration 10-30 seconds
Instagram Reels: Average video duration 10-20 seconds

Conclusion: The vast majority of users generate 10-15 second standard short videos, per-request billing fully covers the need.

2. The "Flexibility Trap" of Per-Second Billing

Official claims "per-second billing is more flexible", but in reality:

❌ API cannot precisely control video duration (usually can only specify "approximate" duration)
❌ Generating 5-second videos doesn't get significant discount (still costs $0.50-$2.50)
❌ Users find it difficult to leverage the "per-second billing" advantage

3. Cost Predictability

Feature	Per-Request Billing	Per-Second Billing
Price Transparency	✅ Fixed price, clear at a glance	⚠️ Need to calculate duration×unit price
Budget Control	✅ Know exact cost upfront	⚠️ Hard to budget precisely
Unexpected Overspending Risk	✅ Zero risk	⚠️ Overspend if video duration exceeds expectations
Suitable for Enterprise Procurement	✅ Easy to set budgets	⚠️ Large cost fluctuations
