We built a latency profiler for AI workflows. Most slowness comes from orchestration and retrieval, not model inference. Here's how to find and fix it.

Quick overview: which tool does what?
The bottleneck in your AI workflow probably isn't the language model—it's everything around it. When you measure where time actually goes in an AI system (waiting for API responses, shuffling data between tools, retrying failed requests), you typically find that **orchestration and data retrieval cost more time than model inference**. Here's how to find and fix it.
Picture this: you've built an AI workflow that works. You feed it a document, it extracts information, summarizes it, routes it somewhere. Technically correct. But the user waits 8 seconds for a result that *should* take 2.
You assume you need a faster model. So you switch from GPT-4 to GPT-4 Mini, or you pay more for priority access. Nothing changes. The real culprit was usually something else—a retrieval step that runs serially when it could run in parallel, a request that retries three times instead of once, or data being fetched and reformatted four different ways before it reaches the model. These invisible losses add up fast.
Most solopreneurs tune the wrong lever. They obsess over model choice because that's the visible, marketable part of an AI stack. But batching requests, caching responses, running steps in parallel, and reducing API calls—these architectural decisions usually move the needle much more than swapping to a "faster" model.
A smaller model with better orchestration beats a huge model run inefficiently. The math is simple: if your workflow makes 15 API calls where it needs 5, no model is fast enough. Start there.
You need visibility into each step. Real latency profilers break down time by component: model inference, data retrieval, API overhead, retries, serialization. Without this breakdown, you're guessing.
For early-stage workflows, you don't need a sophisticated observability platform. Logging request timestamps and durations at each step—and actually reviewing that log—often surfaces the biggest time sinks immediately. The goal is to stop chasing the wrong problem.
Model choice does move the needle—but only after you've eliminated the obvious architectural waste. If your workflow is already batching efficiently and caching where it makes sense, then comparing inference time between Claude 3.5 Sonnet and GPT-4o becomes worthwhile.
For solopreneurs, this usually means starting with a capable mid-tier model (like GPT-4 Mini or Claude Haiku), measuring latency carefully, and only upgrading the model itself if profiling shows you're actually bottlenecked on inference time, not orchestration.
