Compare inference costs across GPT-5, Claude 4.5, Gemini 3, and more.
Now with agentic loops, caching, and reasoning tokens
In 2026, most AI applications use multi-step "agentic loops" rather than single prompts. Calculate costs for workflows like: "5 research steps + 1 summary step = 6 total steps."
Modern APIs (Anthropic, Gemini, OpenAI) offer context caching that reduces input costs by up to 90% for repeated data. Set your cache hit rate to see potential savings.
Reasoning models (like OpenAI's o-series) "think" before responding. These "thinking tokens" cost extra money and are often missed by older calculators. Enable reasoning to see the true cost.

Copy-paste code to integrate GPT-5 into your application
import openai
client = openai.OpenAI(api_key="your-api-key")
response = client.chat.completions.create(
model="gpt-5",
messages=[
{"role": "user", "content": "Your prompt here"}
],
max_tokens=2000
)
print(response.choices[0].message.content)💡 Replace "your-api-key" with your actual API key. Adjust tokens and parameters as needed.
Compare pricing, features, and total cost of ownership between GPT-5 (OpenAI) and Claude 4 Opus (Anthropic). Find out which AI model offers the best value for your use case.
GPT-5 is more affordable

GPT-5 offers lower input pricing at $1.75 per 1M tokens compared to $15.00 for Claude 4 Opus. However, total costs depend on your usage patterns, output requirements, and whether you can leverage context caching. Use the calculator above to estimate costs for your specific use case.
GPT-5 supports up to 256,000 tokens, while Claude 4 Opussupports 200,000 tokens. GPT-5can handle longer documents and conversations without truncation, which is important for applications requiring extensive context.
Yes, many developers use multiple AI models for different tasks. You might use GPT-5for high-volume, cost-sensitive operations and Claude 4 Opus for tasks requiring specific capabilities. The calculator above helps you compare costs across both models.
Both models support context caching, which can significantly reduce costs for repeated inputs. GPT-5 offers cached input at $0.44 per 1M tokens. Claude 4 Opus offers cached input at $1.50 per 1M tokens.Additionally, optimize your prompts, use streaming for faster responses, and consider agentic workflows to minimize token usage.
