Small utilities next to the main calculator. Each one answers a single job. Start here for RAG cost, embedding cost, GPU vs API, context fit, tokenizer comparison, cache savings, or batch pricing, then return to the main token and cost engine.
All tools
- GPU / LLM cost calculatorCompare catalog API spend to cloud GPU rental or purchase amortization. Break-even volume and capacity check.
- Embedding cost calculatorEstimate corpus indexing and query embedding spend. Compare reference embed models and optional batch discounts.
- RAG cost calculatorEstimate corpus embedding, per-query retrieval pack, and generation cost. See which line dominates monthly spend.
- Context window calculatorBudget system, history, RAG, and reserved output against a model window. See fit, headroom, and other models that hold the same total.
- Tokenizer comparisonPaste once and compare Exact OpenAI encodings vs Approx Claude, Gemini, and host tokenizers. See deltas and example cost.
- Token visualizerSee Exact OpenAI token pieces as colored chips with token IDs. Switch o200k and cl100k encodings.
- Tokens ↔ wordsRough Approx converter between words, characters, and tokens for English budgeting.
- Cache savingsEstimate how much prompt caching saves at your hit rate and monthly volume.
- Batch pricingCompare standard vs Batch API cost for the same token profile and job count.
- Cheapest LLM APIRank every catalog model by input rate and an example request of 1000 input tokens and 500 output tokens.
- Cheapest frontier modelsGPT-5, Claude, Gemini Pro, and Grok class rows ranked by published input rate.
- Cheapest models for long repliesRank by output rate plus an example with 2000 output tokens for chat and writing.
- Cheapest long context modelsModels with 128K or larger windows, ranked by input rate, with published tier notes.
- Price one prompt across all modelsPaste a prompt once and see token count plus API cost for every model in the catalog.
- Same model, cheapest hostCompare Groq, Together, Fireworks, and first-party rates when the same model is listed more than once.
