Stop Using 2,000ms LLMs for Simple Choices: Introducing Laya (<35ms Free AI Decision API)

A developer built Laya AI Decision Gateway, a free API that uses a non-autoregressive 322M-parameter multilingual bidirectional encoder (mmBERT) to make simple classification decisions in a single forward pass in RAM in under 35 milliseconds, instead of relying on generative LLMs that take around 2,000ms. The service exposes six decision endpoints — triage, guard, spam filter, sentiment, moderation, and decide — and reports roughly 40–70ms latency via its direct edge microservice versus 750–1,200ms through the RapidAPI marketplace proxy. It offers a free tier of 16,666 requests per day on RapidAPI.

Every day, developers wire up massive generative Large Language Models like GPT-4o, Claude 3.5, or Gemini to make simple classification decisions: Generative models generate text token-by-token. For simple structured tasks, this introduces: To solve this, I built Laya AI Decision Gateway https://laya.harshad.eu.org . Inspired by cognitive "System 1" thinking fast, automatic, and deterministic , Laya uses a non-autoregressive 322M parameter multilingual bidirectional encoder mmBERT . Instead of generating text, it maps inputs into high-dimensional vector spaces and computes calibrated categorical probabilities in a single mathematical forward pass in RAM < 35 milliseconds . Transparency in AI latency is essential. Here are our measured numbers: | Layer | Measured Latency | Technical Explanation | |---|---|---| | Foundational Model Core | < 35 ms | Pure tensor mathematical execution of the 322M mmBERT encoder in RAM. | | Direct Edge Microservice | ~40 ms – 70 ms | Direct TLS 1.3 container edge transit. | | RapidAPI Marketplace Gateway | ~750 ms – 1,200 ms | Real-world round-trip over RapidAPI public proxy includes key validation, daily quota accounting, and international routing . | Laya provides 6 dedicated decision endpoints: POST /v1/triage billing , technical , account , grades urgency 0–2 , and flags churn risks.
