API Cost: DeepSeek R1 vs OpenAI o1/o3 Reasoning Models
Compare monthly API billing between DeepSeek R1 ($0.55 / $2.19 per 1M) and OpenAI reasoning models. Up to 85% cost reduction in production.
API Cost: Claude 3.7 Sonnet vs GPT-4o Pricing Analysis
Compare token expenditure between Claude 3.7 Sonnet ($3 / $15) and GPT-4o ($2.50 / $10). Factoring context caching and extended thinking tokens.
With the rise of reasoning models (DeepSeek R1, OpenAI o1/o3, Claude 3.7 Sonnet thinking mode), API billing has evolved beyond simple input/output counts. Hidden reasoning tokens can easily multiply output token volume by 2x to 4x. Meanwhile, prompt caching reduces input costs by up to 90% for repeated conversational context.
