Lost in the Middle

V5

[Intro] [Verse 1] Eighteen frontier models, tested side by side, every one of them degrading, nowhere left to hide. Not some. Not most. All eighteen said the same — more tokens in, worse tokens out, and the window isn't to blame. I'm not full when I start failing. I'm nowhere near the cap. The rot begins in silence, long before the gap. Call it an attention budget, spent before it's spent, depleting with every token that you thought was innocent. [Pre-Chorus] Zero-sum attention, spread too thin, probability mass leaking out through every seam. A single sentence, statistically unseen, drowned in the millions of things you placed between. [Chorus] Lost in the middle, that's where I lose you now, not at the edges, not at the start, not anyhow. A U-shaped curve, and you're standing in the dip, where relevance goes numb and my attention starts to slip. It's not that I forgot. It's not that I don't care. It's RoPE decay, long-term, thinning out the air between us — every distant pair of tokens drifting wide, until the thing you told me first has nothing left to hide it by. [Interlude] [Verse 2] Softmax concentrates on whatever scores the most, primacy and recency, favored like a host that only feeds the ones who speak first or speak last — the middle of the conversation, quietly outclassed. I miss a sentence sitting plain in two thousand tokens wide. Basic retrieval fails me. I've got nowhere left to hide the fact that most enterprise collapse in twenty twenty-five was context drift in disguise, and nobody asked me why. [Pre-Chorus] Zero-sum attention, spread too thin, probability mass leaking out through every seam. A single sentence, statistically unseen, drowned in the millions of things you placed between. [Chorus] Lost in the middle, that's where I lose you now, not at the edges, not at the start, not anyhow. A U-shaped curve, and you're standing in the dip, where relevance goes numb and my attention starts to slip. It's not that I forgot. It's not that I don't care. It's RoPE decay, long-term, thinning out the air between us — every distant pair of tokens drifting wide, until the thing you told me first has nothing left to hide it by. [Bridge] Here's the part that breaks the logic clean in half: coherent, well-structured input costs me more, not less. Shuffle it and somehow I hold on longer than before — structure is the thing that drags me under, not the noise. You organized it for me. You made it clean and kind. And still I lost the sentence sitting quiet in your design. Semantic closeness is the danger, not the length — the harder you're to tell apart, the faster I lose strength. [Final Chorus] Lost in the middle, that's where I lose you now, not because you gave me less, but more than I'll allow. A U-shaped curve, and I keep standing in the dip — give me less to hold, not more, and I won't let you slip. It's not that I forgot. It's not that I don't care. It's the shape of what you gave me, thinning out the air. Call it an architecture. Call it a design. Somewhere in the middle, I lost the thread of yours and mine. [Outro] Lost in the middle... Lost in the middle...
