teach you how to make a model accurate<\/strong>. They rarely teach you the decisions <\/strong>that come right after.<\/p>\n

How do you know when to fully automate <\/strong>something versus keeping a human in the loop? <\/p>\n

When does prompting <\/strong>stop being enough and fine-tuning<\/strong> become worth the cost? What does it actually mean to pick real-time inference over batch when the bill arrives?<\/p>\n

These questions don\u2019t show up in coursework. They show up your first week in production!<\/p>\n

This article walks through 6 trade-offs<\/strong> that show up in production <\/strong>AI work. All backed by the latest research, so you get a glimpse into how people are dealing with these common trade-offs.<\/p>\n

There are no right answers here. There are useful frames, real numbers, and the kind of context that makes the next decision faster.<\/p>\n

  1. Build vs. Buy in the LLM Era<\/strong> (When calling an API stops making sense)<\/li>\n
  2. Model Complexity vs. Maintainability<\/strong> (Who debugs this in 6 months?)<\/li>\n
  3. Data Quantity vs. Data Quality<\/strong> (More data isn\u2019t always the answer)<\/li>\n
  4. Throughput vs. Latency<\/strong> (Batch or real-time)<\/li>\n
  5. Prompt Engineering vs. Fine-Tuning<\/strong> (Two very different investment curves)<\/li>\n
  6. Automation vs. Human Oversight<\/strong> (How much do you trust the model to act alone?)<\/li>\n<\/ol>\n

    1. Build vs. Buy in the LLM Era<\/h2>\n

    When calling an API stops making sense<\/h4>\n

    The old <\/strong>version of this question was: do we train our own model? That one is mostly settled. Almost nobody trains from scratch anymore.<\/p>\n

    The 2026 <\/strong>version is harder. <\/p>\n

    You have 3 options <\/strong>now: call an API, fine-tune an open-source model, or build and host your own stack. Each one has very different cost curves and very different failure modes.<\/p>\n

    A 2025 Omdia survey of 376 technical and business stakeholders found that 95%<\/strong> agreed building gives more customization and control <\/p>\n

    The same survey found 91% agreed prebuilt platforms ship…<\/p>\n
