There is no census of AI agents. What Microsoft (nearly 40 million agents registered in Agent 365), Salesforce, OpenAI, IDC and Gartner have actually published, what each figure counts, a reproducible count of the official MCP Registry (46,265 servers), and how to count the agents in your own company.
Why total AI inference demand keeps rising even as each token gets cheaper: more users, longer reasoning, agent loops and bigger prompts, with sources.
What published data says about the split between training and inference compute, why the answer differs by company, and why one clean percentage is rare.
What time to first token, inter-token latency and tokens per second mean, how they relate, and why two speed claims often cannot be compared.
