Example
To generate 10 sonnets (each ~100-140 tokens):
- Input Cost: $0.015 - $0.021 (1,000-1,400 tokens × $15/million tokens).
- Output Cost: $0.06 - $0.084 (1,000-1,400 tokens × $60/million tokens).
- Total Cost: $0.075 - $0.105.
Rate Limits
- Rate limits vary based on the API tier:
- Tier 3: 5,000 requests per minute.
- Tier 4: 10,000 requests per minute.

- Cost Breakdown:
- For a typical sonnet (approximately 14 lines, ~100-140 tokens), the cost is calculated as follows:
- Input Cost: $0.0003 - $0.00042 (100-140 tokens × $3/million tokens).
- Output Cost: $0.0015 - $0.0021 (100-140 tokens × $15/million tokens).
- Total Cost per Sonnet: $0.0018 - $0.00252.
- For a typical sonnet (approximately 14 lines, ~100-140 tokens), the cost is calculated as follows:
Subscription Plans
- Anthropic offers on-demand pricing with no long-term commitments.
- Discounts are available for provisioned throughput or bulk usage, though specific rates depend on the volume of tokens purchased.
- Claude Pro: $20/month with increased rate limits and beta features.
- Claude Team: $30/user/month for businesses with user management tools.
- Claude Enterprise: Custom pricing with a larger context window (500,000 tokens).
API Access
- Claude 3.5 Sonnet is accessible via multiple APIs, including:
- Anthropic API

Subscription Plans: While both offer pay-as-you-go, Claude 3.5 Sonnet also provides tiered subscription plans (Pro, Team, Enterprise) for users with higher usage needs, offering additional features and rate limits. GPT-4.5-turbo's access is tied to API usage tiers based on spending history.
Rate Limits: GPT-4.5-turbo's rate limits are tier-based, ranging from 5,000 to 10,000 requests per minute, while Claude 3.5 Sonnet has a fixed rate limit of 5 requests per minute and 20,000 tokens per minute. This difference may impact the speed and volume of content generation.
In conclusion, for generating sonnets, Claude 3.5 Sonnet is the more cost-effective and flexible choice, particularly for users who need to process large volumes of tokens, require a larger context window, or are seeking free-tier testing options. While GPT-4.5-turbo (O1 Preview) offers powerful capabilities, its higher cost and lack of a free tier make it less accessible for many use cases. The choice between the two models should be based on specific needs, budget, and the scale of content generation required.
