MasterAI Now is an interactive academy that teaches how machine learning and large language models (LLMs) work, step by step. Its 11 hands-on stages walk through linear regression, backpropagation, BPE tokenization, self-attention, LoRA fine-tuning, RLHF and DPO alignment, and inference with KV-cache. Each stage explains the idea first, then lets you experiment with a simulation.
Developers also get practical tools: an AI token counter, an LLM API cost calculator, and a cheapest LLM API finder to compare provider pricing. In-depth guides cover real decisions such as estimating tokens before an API call, budgeting TPM and RPM rate limits, and forecasting monthly LLM costs.
