Engineering Tools
Premium, interactive utilities designed to help engineers build, optimize, and scale production-grade AI systems.
Model Intelligence
Compare, rank, and evaluate frontier models.
Architecture & RAG
Design efficient retrieval and generation pipelines.
RAG Chunking Previewer
Visualize how your text is split and see how overlap affects context preservation. Perfect for tuning vector retrieval accuracy.
Local RAG Configurator
Generate optimized Docker and CLI deployment scripts for your specific hardware (Mac, Windows, or Linux).
Vector DB Decision Matrix
Compare Pinecone, Milvus, Qdrant, and more. Rank by latency, scalability, and cost for your RAG stack.
RAG Latency Budgeter
Break down your RAG pipeline latency. Analyze retrieval, reranking, and generation bottlenecks.
Economics & Hardware
Calculate costs, ROI, and hardware requirements for AI.
AI Token Cost Calculator
Compare the absolute latest frontier model pricing including GPT-5.5, Claude 4.7, and DeepSeek-V4. Supports multi-currency unit economics.
AI Hardware ROI Calculator
Calculate the break-even point of buying local GPUs vs. renting Cloud APIs based on your daily token volume.
AI VRAM Calculator
Calculate exactly how much VRAM is required to deploy or fine-tune models. Supports DeepSeek MLA and GQA topologies.
Prompts & Agents
Optimize prompts and build agentic workflows.
System Prompt Meta-Optimizer
Apply frontier engineering patterns like XML tagging and Chain of Thought to your raw prompts for better model adherence.
JSON Schema Tool Designer
Build perfect function-calling schemas for OpenAI and Anthropic agents with a visual editor.
AI Agent Workflow Designer
Architect multi-agent orchestration flows and export ready-to-use YAML/JSON configs for CrewAI or AutoGen.
Fine-Tuning Formatter
Convert raw chat logs into high-quality JSONL training datasets optimized for OpenAI and Anthropic.
Visualizers & Explorers
Deep dive into model architecture and tokens.
Transformer Explainer
Interactive walkthrough of embeddings, self-attention, transformer blocks, and output probabilities, presented inside the AI Mastery tools library with source credit.
Token Inflation Lab
Compare tokenizer efficiency across models. See why a "cheaper" model can be more expensive due to low token density.
Context Window Visualizer
Visualize token depth and performance zones. Find where models "lose the needle" in massive context windows.
