Context Rot: How increasing input tokens impacts LLM performance
Submission URL | 222 points | by kellyhongsn | 50 comments
In an eye-opening report by Chroma, researchers dive deep into the performance intricacies of state-of-the-art Large Language Models (LLMs) when processing extended input lengths. While it's largely assumed that these sophisticated models—like GPT-4.1 and Claude 4—operate consistently across varying context sizes, this study challenges that notion, unraveling the phenomenon of "context rot." As input tokens climb into the millions, model efficacy becomes increasingly erratic, with performance degradation often manifesting in surprising, non-linear ways even on simple tasks.
The study scrutinizes 18 LLMs and crafts nuanced benchmarks that extend beyond traditional tests like the Needle in a Haystack (NIAH). While NIAH primarily gauges straightforward lexical retrieval, the researchers explore complex scenarios requiring semantic understanding and adaptability. Tasks included a transformed version of NIAH with semantic mismatches, varied haystack content, and even conversational question-answer pairs via LongMemEval. Despite their simplicity, these setups consistently expose the non-uniform performance of LLMs with long input lengths.
Crucially, the research underscores that real-world applications, which often involve intricate reasoning and information processing, likely exacerbate these challenges. As models and their context windows swell, there's an urgent need for benchmarks that truly reflect the multifaceted demands of actual use cases. Chroma's findings also highlight task-specific failure patterns, suggesting that unresolved complexities at various sub-tasks might underlie broader performance issues.
For those fascinated by these insights and eager to tackle retrieval challenges in AI applications, Chroma's door is open—they're hiring! In the meantime, their full technical report offers a treasure trove of data and a comprehensive codebase for replicating these critical experiments.
Summary of Discussion:
The discussion revolves around challenges and real-world experiences with large language models (LLMs) handling extensive context windows, particularly related to "context rot" (performance degradation with longer inputs). Key themes include:
-
Model-Specific Issues:
- Users report erratic behavior in models like Gemini Pro and Claude (e.g., Code Opus/Sonnet) when managing long contexts. For instance, summarization or retrieval tasks worsen as context grows, even with relevant data provided.
- Cursor (an AI coding tool) and Gemini 25 Flash face similar issues, with outputs degrading over prolonged sessions.
-
Workarounds & Strategies:
- Compaction/Summarization: Some use summaries or "intelligent compaction" to reduce context length while retaining key information, though this risks data loss.
- RAG (Retrieval-Augmented Generation): Debated as a partial solution for retrieving relevant snippets, but not a cure-all. Critics argue it adds complexity and doesn’t fully replace the need for large contexts.
- Context Management: Users manually clear context, use checkpoints, or partition sessions to reset models. Tools like NotebookLM and Appmaps are cited for chunking/summarizing documents.
-
Technical Limits:
- Attention Mechanisms: Discussion highlights inherent bottlenecks in transformer models (e.g., low-rank attention heads) that struggle to track long sequences, leading to inaccuracies.
- In-Context Learning: Studies show performance can improve with more examples in context, but this competes with the "needle-in-a-haystack" problem of finding relevant data in vast inputs.
-
Real-World Impacts:
- Coding Sessions: Developers note LLMs falter even at 20K tokens, struggling with multi-file projects. Local LLMs are proposed to track context, but tools often lack this feature.
- Creative Writing: One user describes Gemini 25 Flash losing coherence in novel-writing tasks beyond 50K-100K tokens, forcing manual intervention.
-
Broader Implications:
- Benchmark Gaps: Traditional benchmarks (e.g., NIAH) fail to capture real-world complexity. Users advocate for tests mirroring tasks like semantic reasoning or conversational QA.
- Model Behavior: Debate persists on whether longer contexts inherently hurt performance, with some studies suggesting trade-offs based on task design.
Key Takeaway: Context management remains a critical, unsolved challenge. While strategies like RAG and summarization help, no approach fully mitigates context rot. Performance hinges on task complexity, model architecture, and user ingenuity in engineering prompts/workflows.

AI slows down open source developers. Peter Naur can teach us why
Submission URL | 351 points | by jwhiles | 207 comments
In a surprising twist, a recent study by Metr has revealed that AI tools may be hindering the productivity of experienced open source developers, rather than helping them. While these developers anticipated that AI would expedite their work by 24%, the study found it actually took them 19% longer to complete tasks using AI. Despite the slowdown, many still believed that AI had sped them up, demonstrating a fascinating gap between perception and reality.
The study focuses on experienced open source developers who have deep familiarity with their codebases. The results can't be generalized across all developers, particularly those working on less familiar or more modular corporate projects. In those environments, where understanding the entire system may not be as crucial, AI tools might indeed offer more tangible benefits.
The broader discussion falls back to a theory proposed by Peter Naur in his paper "Programming as Theory Building." Naur suggests that programming is fundamentally about forming a mental model of the system. Developers with a well-established understanding of their code may find that AI disrupts this mental alignment, as AI lacks access to the intricate insights these developers hold in their minds. The process of translating complex, nuanced knowledge to AI is cumbersome and often leads to misunderstandings, much like trying to transfer complicated instructions to another person without shared context.
This suggests AI tools might be better suited to developers who don't fully grasp the systems they are working on, or whose environments prioritize fast changes over deep understanding. In such settings, AI could indeed prove advantageous by assisting developers in quickly making satisfactory modifications. Thus, while the study highlights certain limitations of AI tools among seasoned open-source veterans, it also underscores their potential strengths in other contexts, leaving much room for ongoing exploration and application in diverse coding scenarios.
The Hacker News discussion around the study reveals several key themes and debates:
-
Methodology Concerns: Users questioned how the study measured productivity, with some skeptical that a 19% slowdown applies to long-term workflows vs. isolated tasks. Analogies were drawn to flawed real-world experiments (e.g., correlating coffee with work efficiency), highlighting challenges in isolating AI’s impact.
-
Mental Models vs. AI: Many agreed with Peter Naur’s theory that AI disrupts the deep, implicit understanding experienced developers have of their codebases. Commenters likened it to "theory building," where reliance on AI fragments nuanced mental models critical for cohesive system design.
-
Context Dependency: Some argued AI’s value depends on context. For developers in corporate or modular environments (vs. deeply familiar open-source codebases), AI might boost productivity by streamlining quick fixes without requiring full system mastery.
-
Perception vs. Reality: Users compared the disconnect between perceived and actual productivity to navigation apps like Waze (feeling faster vs. being efficient). This mirrors the study’s finding that developers felt more productive with AI despite slower results, sparking discussions about psychological incentives in tools.
-
AI-Generated Code Quality: Concerns arose about AI-generated code’s readability and maintainability. Some noted parallels to Joel Spolsky’s “obsession with code rewrites”—prioritizing short-term speed over long-term clarity—and emphasized the importance of rigorous testing to compensate.
-
Balancing Speed and Depth: Comments reflected tension between rapid iteration (“fast food programming”) and deliberate craftsmanship. Supporters of slower, theory-driven work (à la Knuth) argued AI risks prioritizing superficial speed over deeper system understanding.
Ultimately, the discussion framed AI tools as a double-edged sword: beneficial for commoditized tasks or less critical systems but potentially detrimental when applied to complex, deeply understood projects where developer intuition and coherence matter most.
HoloMem's drop-in holographic tape drive for LTO tape libraries
Submission URL | 20 points | by rbanffy | 4 comments
Today on Hacker News, a fascinating innovation in data storage has emerged from UK startup HoloMem, which is poised to revolutionize LTO tape libraries with a new holographic storage technology. HoloMem is leveraging multi-layer holographic storage that boasts an impressive 50+ year lifespan, and its best feature—it can be seamlessly integrated into existing LTO systems without requiring any software changes.
What sets HoloMem apart from previous attempts at holographic storage is its use of affordable, off-the-shelf components, such as a $5 laser diode, and widely produced polymer sheets. This approach sidesteps the expensive, cutting-edge tech usually involved, making their solution both robust and cost-effective.
Unlike competitors like Cerabyte and Microsoft's Project Silica, which use glass slabs, HoloMem's technology utilizes a tape ribbon that can be read optically. This means existing LTO tape library systems can be effortlessly upgraded to handle higher capacity and lower cost storage, transforming them into hybrid systems that blend traditional LTO tapes with state-of-the-art Holodrive technology.
HoloMem's ribbon is composed of a light-sensitive polymer that encodes data as micro-holographic structures called voxels, which are fixed and immutable. In a testament to its ingenuity, the company is able to store up to 200TB of data on a 100-meter tape, despite its compact size compared to the traditional kilometer-long LTO-10 tapes.
The brainchild of Charlie Gale, a former Dyson engineer with a knack for innovation, this technology traces its roots back to Gale's work on hologram security stickers that could display different images from various viewing angles. His experience with these intricate hologram layers fueled the development of HoloMem, which relies on laser-sensitive polymers that undergo structural changes when exposed to light.
HoloMem's polymer technology is not only advanced but also economically viable, as it uses materials like those found in automotive head-up displays, available at minimal cost. The team has already pushed the boundaries of volumetric density, contemplating how many layers of data they can theoretically and practically achieve.
In short, HoloMem is not just a step forward in data storage technology—it’s a quantum leap poised to metamorphose the landscape of archival storage solutions, marrying capacity, longevity, and sustainability in a neat, affordable package. This remarkable breakthrough is certainly one to watch as it potentially sets new benchmarks in the field.
Summary of Discussion:
The discussion centers around frustrations with the high costs and practicality of LTO tape storage systems, particularly for hobbyists. Users note that LTO tapes and libraries are expensive, with drives costing thousands of dollars and tapes requiring specialized hardware. While LTO offers advantages like durability and sequential storage, the upfront investment and complexity make it inaccessible for casual use.
Alternative solutions are debated, such as using regular hard drives or USB-connected storage. One user suggests linking multiple USB drives via hubs as a cheaper, scalable option, though others express skepticism about bandwidth limitations (USB3 bandwidth caps) and organizational challenges (managing dozens of drives). There's a shared sentiment that hobbyists prioritize cost-effective, simpler setups—like external hard drives or cloud storage—over enterprise-grade solutions like LTO tape libraries.
Key themes include cost barriers of LTO, practicality for non-professionals, and debates around USB-based alternatives versus traditional storage methods.

Daily Digest: AI in Filmmaking Discussions on Hacker News
Projects and Achievements:
- Users highlight AI-generated short films, such as Joanna Stern's project (Wall Street Journal), which utilized tools like Midjourney, Runway, and Sora for video generation. Results are praised for technical execution but noted to require larger budgets for polish.
- Examples like Whisk, FLOW Veo 3, and Dreamina showcase advancements in AI-generated video, lip-syncing, and music (via Suno AI).
Critiques and Limitations:
- Technical Flaws: Discussions point out "AI blemishes"—misspellings, inconsistency in physics, unnatural character motions, and limited narrative depth. One user notes errors like "POLICE" misspelled in a scene, undermining immersion.
- Creative Shortcomings: Plots and story details in AI films are criticized as weak (e.g., disjointed narratives, illogical jazz singer roles). Some compare outputs to "stylized stock footage" versus cohesive storytelling.
- Current Tech Limits: Video models struggle with long-form consistency, rendering beyond seconds, and maintaining object permanence. Tools like Sora remain experimental despite progress.
Debates on Impact:
- Human vs. AI Creativity: While AI tools democratize filmmaking (e.g., indie creators), users argue human directors (Nolan, Wes Anderson) need not fear replacement yet. AI is seen as a tool, not a replacement for nuanced storytelling.
- Training Data Challenges: Limited/variable-quality datasets and rendering constraints hinder models. Some speculate video models are "vastly undertrained" compared to text models like LLMs.
Optimism and Future Outlook:
- Potential: Users predict gradual mainstream adoption as AI improves. Techniques like iterative refinement and hybrid workflows (human + AI) may bridge gaps in consistency and creativity.
- Indie Advantages: Low-budget filmmakers could leverage AI for cost-effective prototyping or stylistic experimentation (e.g., retro black-and-white aesthetics).
Notable Quotes:
- "AI blmeshes [are] distracting—story execution matters more than flashy tech."
- "We’re nearing a point where AI tools let creators focus on artistry, not budget."
Conclusion: While AI filmmaking tools show promise, consensus leans toward viewing them as supplements rather than replacements. Technical flaws and narrative limitations persist, but optimism remains for future advancements reducing barriers for creators.
