About TokenBurner
TokenBurner is a free, open resource for developers and engineering teams to calculate, compare, and optimize AI infrastructure costs.
We built TokenBurner because we were tired of getting surprised by LLM API bills. What started as an internal spreadsheet to track our own AI costs evolved into a comprehensive toolkit used by thousands of developers worldwide.
Our Mission
AI APIs are powerful, but pricing is complex. Between input/output tokens, batch discounts, prompt caching, and per-request fees, it's nearly impossible to estimate costs without a calculator.
Our mission is to give developers full transparency into AI costs so they can make informed decisions about model selection, architecture, and budget allocation.
What We Offer
LLM Cost Calculator
Calculate exact costs for GPT-5.2, Claude 4.5, Gemini 3.0, and 50+ other models. Input your token usage and see real-time pricing breakdowns.
Vector DB Pricing
Compare Pinecone, Weaviate, Qdrant, and other vector databases. Understand storage vs. operation costs before you deploy.
VRAM Calculator
Check if your GPU can run local LLMs. We calculate memory requirements for Llama, Mistral, and other open-source models.
Our Values
Accuracy First
We maintain up-to-date pricing data from official API documentation. Our calculations reflect real-world costs including batch discounts and prompt caching.
Developer-Focused
Every tool and article is written by developers, for developers. We skip the marketing fluff and focus on actionable insights.
Privacy by Design
All calculations run client-side in your browser. We never transmit or store your prompts, token counts, or any calculation inputs.
Who We Are
TokenBurner is created and maintained by independent developers with hands-on experience building AI-powered applications.
We've built RAG pipelines, fine-tuned models, optimized inference costs, and debugged unexpected API bills. Every tool and article on TokenBurner comes from real-world experience—not theoretical knowledge.
Our content is written by practitioners who actively work with LLMs, vector databases, and AI infrastructure. We update our pricing data regularly and verify it against official API documentation.
Data Accuracy & Methodology
Pricing Sources: All pricing data is sourced directly from official API documentation and pricing pages. We update our database regularly to reflect the latest changes.
Calculations: Our calculators use standard token counting methods and official pricing formulas. For complex scenarios (batch processing, prompt caching), we document our assumptions clearly.
Transparency: If we're unsure about a price or calculation method, we say so. We'd rather be honest about uncertainty than give you incorrect numbers.
Content Policy
Original Content: All articles, guides, and analyses on TokenBurner are original work. We don't scrape, copy, or auto-generate content.
Practical Focus: We prioritize actionable insights over theoretical discussions. Every article includes real numbers, code examples, or step-by-step guidance.
Regular Updates: AI pricing and best practices change rapidly. We review and update our content to ensure it remains accurate and relevant.
