AI App Cost Savings Video Series

What it does

Watch a practical developer-focused video series on reducing LLM costs in production AI apps without making products slower or weaker. The first batch covers six cost leaks: wrong model choice, duplicate calls, oversized context, broken prompt caching, unnecessary reasoning, and real-time calls that could be batched. Treat AI cost control as engineering, not a billing surprise.

Watch a practical developer-focused video series on reducing LLM costs in production AI applications without making products slower or weaker.

Practical engineering patterns for reducing LLM costs in production apps. AI features are getting easier to build, but harder to operate profitably. Once you move beyond a prototype, every model choice, repeated request, oversized context window, retry, tool definition, test run, reasoning setting, and real-time call can quietly turn into margin leakage. Most AI cost problems are not just model pricing problems. They come from engineering choices that compound as usage grows. Watch the first batch of videos and start applying practical cost controls to prompts, model routing, duplicate request handling, context management, caching strategy, reasoning settings, and batch workflows.

  Argmin AIJul 2026 · argminai.com · ▲32

  Hey, HN community! We've built Argmin AI after shipping LLM features where the demo worked, then the bill and latency got unpredictable in production. Prompts expanded, context grew, retrieval got noisy, retries appeared, and agent workflows added loops. Argmin AI optimizes LLM-related expenses as a system: 1. prompt and context efficiency 2. model selection and routing 3. RAG inefficiencies and caching opportunities 4. agent workflows (tool calls, retries, loop control) Changes are validated with evals and guardrails (tests, gates, judges), tailored to your quality definition and goals.…

  I built a frontpage for personal blogs▲783

  With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
