AI calculators and visual simulators
Change the assumptions yourself. Lumaria calculates locally, visualizes the system and helps you compare scenarios without requiring an API.
AI API cost calculator
Estimate cost per request, day, month and year using prices you control.
Open calculator →CostsPrompt caching savings calculator
Estimate how repeated context and cache pricing can change monthly inference cost.
Open calculator →RAGEmbedding storage calculator
Estimate vector storage from item count, dimensions and numeric precision.
Open calculator →ProductionBatch vs realtime calculator
Compare approximate economics of batch and realtime processing.
Open calculator →ProductionThroughput and concurrency planner
Estimate request concurrency from volume, latency and target throughput.
Open calculator →DecisionAI model comparator
Compare selected models using the verified dataset behind Lumaria IA.
Open calculator →RAGRAG chunk designer
Explore chunk size, overlap, chunk count and repeated-token overhead.
Open calculator →DecisionWeighted model decision matrix
Turn model selection into explicit weighted criteria rather than a universal ranking.
Open calculator →ProductionRate-limit planner
Translate RPM/TPM limits into practical capacity and headroom.
Open calculator →CostsAPI budget planner
Plan monthly API spend from request volume and unit economics.
Open calculator →ContextContext window planner
Visualize how prompt, document, history and output consume context.
Open calculator →BusinessAI automation ROI calculator
Estimate time savings, operating cost, break-even and potential ROI.
Open calculator →EvalsEval sample-size planner
Estimate how many examples you need for a useful evaluation sample.
Open calculator →InfrastructureModel VRAM calculator
Estimate model memory from parameter count, precision, KV cache and overhead.
Open calculator →ProductionLatency budget designer
Break total latency into network, retrieval, model, tools and post-processing.
Open calculator →AgentsAgent cost calculator
Estimate cost per task from model calls, tokens, tool steps and retries.
Open calculator →DecisionModel routing simulator
Compare a single-model strategy with a routed mix of cheaper and stronger models.
Open calculator →InfrastructureLocal model vs API break-even
Estimate where hardware ownership and cloud API usage cross over.
Open calculator →ContextDocument vs context calculator
Estimate whether a document fits and how much context remains for output and history.
Open calculator →ProductionBatch capacity planner
Estimate how many jobs a batch window can process under throughput constraints.
