LLM & AI API Cost Calculator Hub
Compare 40+ large language models across 9 providers. Calculate API costs, estimate token usage, plan RAG architecture, explore capabilities, and find the best AI model for your use case — with live multi-currency pricing in USD, INR, EUR, GBP, JPY and more.
Calculators & Tools
Every tool reads from a single centralized data source, so updating one JSON file refreshes all pricing, comparisons, and calculators across the hub.
AI API Cost Calculator
Estimate costs for prompts, completions, images, audio, embeddings and RAG pipelines using realistic workloads.
LLM Token Calculator
Estimate token counts for text and code, compare token-to-cost across models, and optimize prompt length.
AI Model Comparison
Compare up to 5 models side-by-side with sticky columns, radar charts, benchmark overlays and CSV/PDF export.
AI Cost & Architecture Planner
Answer questions about requests, tokens, concurrency, RAG and budget to get a recommended architecture with cost and latency.
AI Capability Explorer
Interactive visualization of coding, reasoning, vision, audio, multilingual, tool calling, structured output and context length.
AI Model Decision Wizard
A guided flow that recommends models with explanations and trade-offs based on your use case, budget and constraints.
AI Use Case Hub
Coding, writing, research, customer support, legal, finance, healthcare, marketing, education, analytics, image generation and more.
AI Prompt Library

Why a Centralized LLM Catalog?
Model names and prices change every few weeks. Instead of hardcoding pricing into each page, this hub uses a single JSON data source (data/ai/llm-catalog.json) that every calculator, comparison table, and recommendation engine reads from. Update one file and the entire site refreshes.
What's Inside the Catalog
- Providers: OpenAI, Anthropic, Google, DeepSeek, Mistral, Meta, Qwen, Cohere, xAI
- Models: 40+ chat, reasoning, embedding, audio, and image generation models
- Pricing: Input, output, cache read, cache write, batch, tiered, per-image, per-second, per-character
- Capabilities: Vision, reasoning, tool calling, parallel tools, structured output, streaming, prompt caching, web search, audio I/O, PDF input, multilingual
- Benchmarks: MMLU, HumanEval, GPQA, MATH, MBPP
- Metadata: Release date, status (current/legacy), context window, max output, feature flags
- Use cases: 13 evergreen intent categories mapped to recommended models
- Changelog: Versioned history of pricing and capability changes
SEO-First Architecture
This hub follows a pillar → provider → model → calculator → comparison → guide → FAQ → glossary → changelog structure. Each page targets one primary keyword with no cannibalization. Evergreen intent pages (like "AI API Cost Calculator" and "LLM Token Calculator") form the core, while individual model pages act as supporting content fed from the centralized data source.

Frequently Asked Questions
How accurate is the LLM pricing on this site?
Pricing is sourced from public provider documentation and LiteLLM's community-maintained reference file. We store canonical prices in USD and convert dynamically. Always verify current pricing on the provider's official pricing page before production use, because prices change frequently.
Which currencies are supported?
USD, INR, EUR, GBP, JPY, AUD, CAD, SGD and AED. Select your currency from the toolbar and every price on every page updates instantly. Exchange rates are conservative static estimates — for billing, your provider charges in USD.
How often is the catalog updated?
The catalog is versioned with a changelog. When a provider changes pricing or releases a new model, we update the single JSON file and every page reflects the change. The "last updated" timestamp is shown in the toolbar.
Can I use these calculators for production budgeting?
Yes — the calculators use real formulas (tokens × per-token price) with options for batch API discounts, prompt caching, and reasoning tokens. For high-volume production, add a 10-20% buffer for token estimation variance and cache-miss scenarios.
What is the difference between the Cost Calculator and the Architecture Planner?
The Cost Calculator estimates the cost of a specific workload on a specific model. The Architecture Planner takes your business requirements (requests, concurrency, RAG, budget, latency) and recommends a provider architecture with estimated monthly cost, latency, and trade-offs.
Do you store my inputs?
No. All calculations run entirely in your browser. Currency preference and theme are stored in localStorage. No data is sent to any server.
