Explore free AI tools from Crazyrouter to compare AI API pricing, estimate token costs, evaluate GPT vs Claude vs Gemini vs DeepSeek, and choose the right model for production. Built for developers who want faster decisions, lower costs, and one API across 627+ models.
Use these tools to compare AI API costs, estimate token-based pricing, evaluate popular models, and choose the best API setup for your product. Start with pricing today, then move into deeper model comparison, ranking research, and release intelligence.
Most AI API websites give you docs and price tables. We want to give you decision-making tools — the kind that help you compare models, estimate cost, and understand tradeoffs before you commit engineering time.
These pages are built to match real queries developers search for: AI API pricing calculator, GPT vs Claude comparison, token cost estimator, and model selection guides.
Each tool page is meant to do double duty: rank for useful keywords and convert serious developers into product users through a clean, product-led experience.
Useful tools build trust first. Then the natural next step is using Crazyrouter itself: one API key, 627+ models, lower pricing, and less vendor lock-in.
These are the kinds of questions developers usually have before choosing an AI API provider, a model stack, or a cost optimization strategy.
If you are already looking for an AI API pricing calculator, there is a good chance you are also comparing API gateways. Crazyrouter is built for the same core need — one key, many models — but pushes further on pricing, modality coverage, and production flexibility.
The tools help you evaluate. The product helps you ship. Once you know the models and price range you want, plugging Crazyrouter into your app is straightforward.
from openai import OpenAI
client = OpenAI(
api_key="YOUR_CRAZYROUTER_KEY",
base_url="https://crazyrouter.com/v1"
)
resp = client.chat.completions.create(
model="gpt-5-mini",
messages=[
{"role": "user", "content": "Hello from Crazyrouter"}
]
)
print(resp.choices[0].message.content)
Use these pages to research AI model pricing, compare GPT vs Claude vs Gemini vs DeepSeek, and estimate production costs before you write code. When you are ready to ship, Crazyrouter gives you one OpenAI-compatible API for 627+ models across text, image, video, audio, and more.
