Speed Demon: 5 Ways to Squeeze Latency Out of Your AI Models

Fast moving streaks of light.

The Latency Crisis

Modern LLMs are heavy. A single request can take seconds, and in the world of web apps, every millisecond counts. If your AI feels “slow,” it’s not the model’s fault—it’s your infrastructure.

5 Pro Tips for 2025

  1. Quantization: Use 4-bit or 8-bit GGUF/EXL2 weights instead of full 16-bit precision. You get a 2x-4x speed boost with almost zero loss in intelligence.
  2. Streaming: Don’t wait for the full response. Use Server-Sent Events (SSE) to stream tokens character-by-character. It doesn’t make the math faster, but it makes the UX feel instant.
  3. KV Caching: Reuse the context you’ve already processed. Techniques like FlashAttention optimize how the model remembers previous tokens.
  4. Speculative Decoding: Use a tiny, lightning-fast “draft” model to predict text, and let the giant “pro” model just verify the result.
  5. Batched Inference: Process multiple users on the same GPU pass. It increases throughput and reduces the “wait time” for individual requests.

The Bottom Line

Deep learning isn’t just about training anymore; it’s about Inference Engineering. The best models in the world are useless if the user is staring at a loading spinner.
