When it comes to choosing an AI model for your projects, pricing often becomes the deciding factor. OpenAI and DeepSeek are two major players in the AI space, each offering different pricing structures that can significantly impact your budget. Let's dive into a detailed comparison to help you make an informed decision.

OpenAI Pricing Structure

OpenAI's GPT-4 has been the gold standard for large language models since its release. The company offers several pricing tiers, with GPT-4 Turbo being their most advanced and cost-effective option.

GPT-4 Turbo Pricing

• Input tokens: $0.01 per 1K tokens
• Output tokens: $0.03 per 1K tokens
• Context window: 128K tokens
• Knowledge cutoff: April 2023

GPT-4 Original Pricing

• Input tokens: $0.03 per 1K tokens
• Output tokens: $0.06 per 1K tokens
• Context window: 8K tokens

This represents a significant reduction from the original GPT-4 pricing, making GPT-4 Turbo much more accessible for developers.

DeepSeek Pricing Structure

DeepSeek has positioned itself as a more affordable alternative, particularly for coding tasks. Their pricing model is straightforward and transparent.

DeepSeek Coder Model

• Input tokens: $0.0014 per 1K tokens
• Output tokens: $0.0028 per 1K output tokens
• Context window: 128K tokens
• Specialization: Coding-focused

DeepSeek General Model

• Input tokens: $0.002 per 1K tokens
• Output tokens: $0.004 per 1K tokens
• Context window: 128K tokens

Direct Price Comparison

Real-World Cost Examples

Let's look at some practical examples to understand the cost difference:

Example 1: Code Review Session

• Input: 5,000 tokens (code + context)
• Output: 2,000 tokens (review comments)
• GPT-4 Turbo cost: $0.05 + $0.06 = $0.11
• DeepSeek Coder cost: $0.007 + $0.0056 = $0.0126
• Savings: 88% with DeepSeek

Example 2: Content Generation

• Input: 1,000 tokens (prompt)
• Output: 3,000 tokens (article)
• GPT-4 Turbo cost: $0.01 + $0.09 = $0.10
• DeepSeek General cost: $0.002 + $0.012 = $0.014
• Savings: 86% with DeepSeek
