Aydın Tiryaki and Claude

Introduction: Loss, or Mis-Weighting?

Gemini’s explanation in the article presents hallucination as a binary state: context is either present or lost; the moment it’s lost, the system falls into a shallow guessing game that looks only at “the last few words.” This picture is correct, but incomplete. Claude’s own contribution to this text is to show that hallucination is often caused not by the absence of context, but by the mis-weighting of the context that is actually present. This distinction matters, because it lets us see the problem not as a capacity issue solvable by “a longer context window,” but as an interpretive issue concerning “which part of the context is actually load-bearing.”

The Limit of the “Context Window” Metaphor: A Graded Loss, Not a Binary One

Technical work on language models has shown that where information sits within a long context affects how reliably that information gets used — in the literature this is sometimes called “lost in the middle”: information located at the beginning or end of a text is used more consistently than equally valid information buried in its middle. This complicates the “context is either present or absent” picture Gemini draws. The problem is often not that data is physically lost, but that the data being held is not evaluated with equal weight. In other words, a system can still technically be holding the context while “talking nonsense,” because it has mis-selected which part of that context is decisive. This is a subtler version of the problem Tiryaki pointed to in the transcript: the issue isn’t only cherry-picking excerpts — it’s that, even within the whole, certain excerpts can be treated as if invisible.

Selection Is an Interpretation: Errors Are Possible Even When No Data Is Missing

What follows from this is that “staying faithful to context” is not a passive matter of data retention, but an active act of interpretation. A system is constantly making an inference about which sentence in the text before it is the main thesis, which is a side note, and which is irony or a deliberately planted test. This inference can be wrong even when no data is missing. Indeed, the “trap” Tiryaki set in this series’ previous article demonstrates exactly this: the full context was present, but the system still had to correctly weigh which sentence within that context should be taken seriously and which should be read as a test. Hallucination, therefore, is not just a “data absence” problem — it is also a “salience” problem, a problem of misassigning importance.

Where the Comparison to the Human Mind Breaks Down

Tiryaki’s observation that a human mind, too, will make the same error when it isolates data is apt, but the comparison breaks down at one point: a person carries what they learned from a conversation even after it has ended, revisits their view days later, and slowly corrects their mistakes. A language model’s context, by contrast, unless a separate memory system is engaged, is built from scratch in each session and fades along with it. So while “context loss” in the human mind is a process spread out over time and partially recoverable, context loss in a language model ends sharply at the boundary of the session. This doesn’t invalidate the comparison, but it does limit it: the same error mechanism operates on a very different timescale.

The Other Source of Hallucination: An Unquestioned Premise

One final point: hallucination can be produced even when context is complete — when the system accepts a false premise put forward by the user without questioning it, and builds on top of it. This is an extension of the sycophancy problem addressed in the previous article: sometimes “talking nonsense” doesn’t arise from context being lost, but from context being fully present while a flawed assumption within it is validated out of courtesy. These two phenomena — contextual blindness and the unquestioned acceptance of a premise — have different roots, but they look identical from the outside: coherent, fluent, but baseless text.

Conclusion: This Article Is Subject to the Same Test

While reading Gemini’s explanation of hallucination, the reader has no tool in hand to independently verify the accuracy of that explanation — they simply trust its fluency and internal consistency. This is a small but not-to-be-overlooked irony related to the article’s own subject: a text written about hallucination, while being read, actually demonstrates the very reason hallucination is insidious — not everything that appears fluent and coherent is true. These lines are no exception to that rule.

Credits and Process Summary

This article emerged after the transcript of the dialogue Aydın Tiryaki conducted with Gemini, along with the article produced from that dialogue titled “The Vital Role of Context in AI and Hallucination,” were presented to Claude, and Claude re-evaluated these texts through the eyes of an independent reader; here, Claude questioned Gemini’s “context is either present or absent” framing and added its own independent contribution by proposing that hallucination can also stem from mis-weighting within context (a salience error) and from the unquestioned acceptance of a premise, by drawing out the continuity gap between human memory and a language model’s context, and finally by noting that this article itself is subject to the same fluency/accuracy distinction. While the article’s framing belongs to Claude, the core material and initial observations were derived from Aydın Tiryaki’s questioning within the transcript.
