At its core is the <strong>self-attention<\/strong> mechanism, which allows the model to dynamically assess the relationships between input tokens. But what does all of this actually mean when you open the IDE?  <\/p>\n\n<p>First of all, LLM APIs are inherently <em>stateless<\/em>. Each call must include the entire necessary context. This immediately runs into the <strong>Context Window<\/strong>: a hard limit on the number of tokens that can be processed. Managing this window requires architectural strategies like chunking and summarization to avoid skyrocketing costs (which are charged per input and output token) or running into annoying HTTP 429 Rate Limit errors.   <\/p>\n\n<p>Another critical hurdle is <strong>latency<\/strong>. Waiting 5\u201310 seconds for a standard HTTP response can ruin the user experience. The solution? Implement Server-Sent Events (SSE) on the backend to stream tokens to the frontend in real time.   <\/p>\n\n<p>When designing the infrastructure, there are two options:<\/p>\n\n<ul class=\"wp-block-list\">\n<li><strong>Cloud APIs (OpenAI, Anthropic, Google)<\/strong>: Immediate setup with no hardware to manage. However, this exposes you to vendor lock-in and unpredictable latency. The best practice here is to use gateways (like LiteLLM) to implement automatic fallback logic if a provider goes offline.  <\/li>\n\n\n\n<li><strong>Open Source Self-Hosted (Llama 3, Mistral, Qwen)<\/strong>: Provides predictable latency and complete privacy for company data. The challenge? You need hardware (GPUs like NVIDIA A100 or H100) and must manage advanced inference engines (like vLLM or TGI) to optimize VRAM usage and batch simultaneous requests.  <\/li>\n<\/ul>\n\n<p>Our architectural recommendation: <strong>always start with Cloud models<\/strong> to validate the use case and ROI. Consider migrating to a self-hosted cluster only when production volumes make API costs unsustainable or if compliance requires it from day one.<br \/> <br \/> <br \/> <\/p>\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" width=\"1024\" height=\"558\" src=\"https:\/\/www.azzurrodigitale.com\/wp-content\/uploads\/2026\/04\/fbd06006-af95-40e7-aeee-03274e626a16-1024x558.png\" alt=\"\" class=\"wp-image-35504\" srcset=\"https:\/\/www.azzurrodigitale.com\/wp-content\/uploads\/2026\/04\/fbd06006-af95-40e7-aeee-03274e626a16-1024x558.png 1024w, https:\/\/www.azzurrodigitale.com\/wp-content\/uploads\/2026\/04\/fbd06006-af95-40e7-aeee-03274e626a16-300x164.png 300w, https:\/\/www.azzurrodigitale.com\/wp-content\/uploads\/2026\/04\/fbd06006-af95-40e7-aeee-03274e626a16-768x419.png 768w, https:\/\/www.azzurrodigitale.com\/wp-content\/uploads\/2026\/04\/fbd06006-af95-40e7-aeee-03274e626a16.png 1280w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n<h2 class=\"wp-block-heading\" id=\"Conclusione-e-prossima-puntata\"><span class=\"ez-toc-section\" id=\"Conclusion_and_Next_Episode\"><\/span>Conclusion and Next Episode<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n<p>Today, you have a clear vision: what LLMs are, why it\u2019s worth investing in them now, and the real technical challenges of integrating them at an architectural level.<\/p>\n\n<p>But knowing the tool is just the first step. <strong>How do you use it to achieve reliable results?<\/strong><\/p>\n\n<p>Nella prossima puntata vi portiamo nel cuore della questione: &#8220;<strong>Prompt Engineering: l&#8217;arte di parlare con l&#8217;AI<\/strong>&#8220;.
