\n RAG: The Answer Is Right, But Where’s the Evidence? The AI confidently gave the right answer. But when you checked the citation it provided, the quoted passage didn’t actually support the answer. Or perhaps the answer needed two pieces of evidence, but only one was cited. Can we really trust a system like this for important work? This is where the limitations of traditional RAG become clear. Until now, many RAG systems have focused on “finding relevant documents and generating an answer.” But reliability in practice isn’t determined by whether a sentence merely sounds like the right answer. What matters more is whether the system has secured sufficient, verifiable evidence for every claim in its answer . The Answer and the Evidence Are Two Different Problems A typical RAG pipeline retrieves document passages—or chunks—that are semantically close to the question, then places them in the LLM’s input context. The model then generates an answer based on the sea...

\n Typhoon Champi’s Track: Tension Builds as It Turns Northeast Typhoon Champi, the 30th typhoon of the year, was heading toward waters near Taiwan—but the chances are growing that it could turn northeast earlier than expected . Why does that turn matter? A slight change in direction could determine whether the storm’s center passes over waters south of Jeju or moves closer to Japan’s Kyushu. The leading scenario for Typhoon Champi’s track has it passing east of Taiwan, then turning north or northeast around October 25. By the 26th, it could approach waters south of Jeju or west of Kagoshima, Japan. After that, it may pass through southern Japan and gradually transition into an extratropical cyclone. But it is too soon to let your guard down. Even if the typhoon does not make direct landfall on the Korean Peninsula, warm, moist air drawn north from the south could flow into Jeju and the southern parts of the country, fueling intense rain clouds. In other words,...

\n An AI with Memories, the Son Who Came Home What if an AI could recreate a parent’s memories more accurately than the son who returned after nine years? Who is the “real son” a parent loves—the person who has come back in the flesh, or the being who brings the voices, expressions, and memories of the past back to life exactly as they were? The question posed by the film Paradise Lost is more than a simple sci-fi fantasy. A son who had gone missing returns, but his parents already have an AI version of him—one that has learned his memories and manner of speaking. The AI perfectly recreates the affectionate conversations and childhood habits his parents remember. The real son, meanwhile, has spent nine years living a life unfamiliar to them and has changed from the person they remember. In that moment, the family’s understanding of who belongs begins to waver. If he shares their genes, does that make him their son? If it perfectly shares the memories he made...

\n Software Infrastructure: The GPUs Are Busy, So Why Are Responses Still Slow? Users may think they’re asking the same question, yet some requests get answered almost instantly while others take much longer. GPU utilization is high, and you’ve added plenty of servers. The cause may not simply be a lack of GPU capacity. The key issue is that requests are scattered across servers that have no memory of the previous conversation . Before generating a response, an LLM must first read the user’s prompt and conversation history. The intermediate state created during this process is called the KV cache (Key-Value Cache) . If the next request in the same conversation is routed back to the server that handled the previous one, it can reuse the KV cache already stored there. But if the request goes to a different server, the previous context has to be recomputed. Typical load balancing User request A → Replica 1 User request B → Replica 2 User request C → Replica 3 Th...
