From Python3.8 to Python3.10: Our Journey Through a Memory Leak

Image generated with ChatGPT (OpenAI), 2025. Intro When working with Python, memory management often feels like a solved problem. The garbage collector quietly does its job, and unlike C or C++, we rarely think about malloc or free. This doesn’t mean that there are no memory leaks in Python. Reference cycles, unreleased resources like connection pooling, global caches, etc can slowly inflate your process’s memory footprint. You might not notice it at first, until your worker starts OOM-ing, latency creeps up, or container restarts become mysteriously frequent. In this post, we’ll share the story of a real-world memory leak we encountered during a Python upgrade — how we discovered it, the tools and techniques we used to investigate, and the lessons we learned. What happened after upgrading to Python 3.10? Back in the summer of 2024, we had an initiative at Lyft to upgrade all of our Python services from v3.8 to 3.10 as v3.8 was scheduled to be EoL by the end of 2024. You can find more details on how our awesome Backend Foundations team at Lyft does Python upgrade across hundreds of repos at scale here . The upgrade involved two phases: the first phase was to upgrade all the dependencies to be Python 3.10 compatible, and the second phase was to upgrade the services to Python 3.10. The dependency upgrades went smoothly for all services and then the phase to upgrade all services to Python 3.10 rolled out. While all services were running Python 3.10 smoothly, there was one servi…

Titans: Learning to Memorize at Test Time (Paper Analysis)

Paper: https://arxiv.org/abs/2501.00663 Abstract: Over more than a decade there has been an extensive research effort on how to effectively utilize recurrent models and attention. While recurrent models aim to compress the data into a fixed-size memory (called hidden state), attention allows attending to the entire context window, capturing the direct dependencies of all tokens. This more accurate modeling of dependencies, however, comes with a quadratic cost, limiting the model to a fixed-length context. We present a new neural long-term memory module that learns to memorize historical context and helps attention to attend to the current context while utilizing long past information. We show that this neural memory has the advantage of fast parallelizable training while maintaining a fast inference. From a memory perspective, we argue that attention due to its limited context but accurate dependency modeling performs as a short-term memory, while neural memory due to its ability to memorize the data, acts as a long-term, more persistent, memory. Based on these two modules, we introduce a new family of architectures, called Titans, and present three variants to address how one can effectively incorporate memory into this architecture. Our experimental results on language modeling, common-sense reasoning, genomics, and time series tasks show that Titans are more effective than Transformers and recent modern linear recurrent models. They further can effectively scale to larger…

Why Vision Language Models Ignore What They See with Munawar Hayat - #758

In this episode, we’re joined by Munawar Hayat, researcher at Qualcomm AI Research, to discuss a series of papers presented at NeurIPS 2025 focusing on multimodal and generative AI. We dive into the persistent challenge of object hallucination in Vision-Language Models (VLMs), why models often discard visual information in favor of pre-trained language priors, and how his team used attention-guided alignment to enforce better visual grounding. We also explore a novel approach to generalized contrastive learning designed to solve complex, composed retrieval tasks—such as searching via combined text and image queries—without increasing inference costs. Finally, we cover the difficulties generative models face when rendering multiple human subjects, and the new "MultiHuman Testbench" his team created to measure and mitigate issues like identity leakage and attribute blending. Throughout the discussion, we examine how these innovations align with the need for efficient, on-device AI deployment.

The complete guide to Node.js frameworks

Node.js is one of the most popular server-side platforms, especially for web applications. It gives you non-blocking JavaScript without a browser, plus an enormous ecosystem. That ecosystem is one of Node’s chief strengths, making it a go-to option for server development. This article is a quick tour of the most popular web frameworks for server development on Node.js . We’ll look at minimalist tools like Express.js, batteries-included frameworks like Nest.js, and full-stack frameworks like Next.js. You’ll get an overview of the frameworks and a taste of what it’s like to write a simple server application in each one. Minimalist web frameworks When it comes to Node web frameworks, minimalist doesn’t mean limited. Instead, these frameworks provide the essential features required to do the job for which they are intended. The frameworks in this list also tend to be highly extensible, so you can customize them as needed. With minimalist frameworks, pluggable extensibility is the name of the game. Express.js At over 47 million weekly downloads on npm, Express is one of the most-installed software packages of all time—and for good reason. Express gives you basic web endpoint routing and request-and-response handling inside an extensible framework that is easy to understand. Most other frameworks in this category have adopted the basic style of describing a route from Express. This framework is the obvious choice when you simply need to create some routes for HTTP, and you don’t m…

In this episode, Zain Asgar, co-founder and CEO of Gimlet Labs, joins us to discuss the heterogeneous AI inference across diverse hardware. Zain argues that the current industry standard of running all AI workloads on high-end GPUs is unsustainable for agents, which consume significantly more tokens than traditional LLM applications. We explore Gimlet’s approach to heterogeneous inference, which involves disaggregating workloads across a mix of hardware—from H100s to older GPUs and CPUs—to optimize unit economics without sacrificing performance. We dive into their "three-layer cake" architecture: workload disaggregation, a compilation layer that maps models to specific hardware targets, and a novel system that uses LLMs to autonomously rewrite and optimize compute kernels. Finally, we discuss the complexities of networking in heterogeneous environments, the trade-offs between numerical precision and application accuracy, and the future of hardware-aware scheduling.

How do you identify and reduce artifacts in Neural Vocoders?

I’m evaluating a few neural vocoders (HiFi-GAN, Vocos, etc.) and I’m seeing the same type of artifact across all of them. I’m not sure exactly what it is, and I’m looking for help identifying it and figuring out how to reduce or remove it. Overall, the models can generate very good audio. In some cases the output is almost indistinguishable from the ground truth. But in other cases, there’s a consistent artifact that’s clearly audible. I’m not an audio expert, so I tried to inspect the signals visually. I plotted both the ground truth (GT) and the predicted audio (PRED) as: waveform (time domain) spectrogram (frequency domain) For the GT audio https://drive.google.com/file/d/1u_p9j29khFrnuqVoHxt8dQ9RgTcjyhpc/view?usp=sharing : The waveform looks “healthy” or “full”. The spectrogram also looks clean and well-structured, and the audio sounds perfect. For the PRED audio https://drive.google.com/file/d/14dsXOZR7JmOwnmNG3kFh6p5Cr7nagrBP/view?usp=sharing : The waveform looks much “thinner” than the GT, like it’s missing energy or detail. In the spectrogram, there are visible “smudges” or “stains” that line up with the artifacts I’m hearing. My intuition is that I might need a better loss function that explicitly penalizes these types of artifacts so the generator learns to avoid them. In the model used to generate the PRED audio, I already implemented a Multi-Resolution STFT loss, which helped to some extent, but the artifacts are still present. This seems to happen with multiple…

What is devops? Bringing dev and ops together to build better software

A portmanteau of “development” and “operations,” devops emerged as a way of bringing together two previously separate groups responsible for the building and deploying of software. In the old world, developers (devs) typically wrote code before throwing it over to the system administrators (operations, or ops) to deploy and integrate that code. But as the industry shifted towards agile development and cloud-native computing , many organizations reoriented around modern, cloud-native practices in the pursuit of faster, better releases. This required a new way to perform these key functions in a more streamlined, efficient, and cohesive way, one where the old frustrations of disconnected dev and ops functions would be eliminated. With two groups working together, developers can rapidly roll out small code enhancements via continuous integration and delivery rather than spending years on “big bang” product releases. Devops was born at cloud-native companies like Facebook, Netflix, Spotify, and Amazon; but it’s become one of the defining technology industry trends of the past decade, primarily because it bridges so many of the changes that have shaped modern software development. As agile development and cloud-native computing have become ubiquitous, devops has enabled the entire industry to speed up its software development cycles. Thus, devops has now thoroughly infiltrated the enterprise, especially in organizations that rely on software to run their business, such as banks,…

Where did it all go wrong? A hierarchical look into multi-agent error attribution

Error attribution in Large Language Model (LLM) multi-agent systems presents a significant challenge in debugging and improving collaborative AI systems. Current approaches to pinpointing agent and step level failures in multi-agent interaction traces—whether using all-at-once evaluation, step-by-step analysis, or binary search—fall short when analyzing complex patterns, struggling with both accuracy and consistency. We present ECHO (Error attribution through Contextual Hierarchy and Objective consensus analysis), a novel algorithm that combines hierarchical context representation, objective analysis-based evaluation, and consensus voting to improve error attribution accuracy. Our approach leverages a positional-based leveling of contextual understanding while maintaining objective evaluation criteria, ultimately reaching conclusions through a consensus mechanism. Experimental results demonstrate that ECHO outperforms existing methods across various multi-agent interaction scenarios, showing particular strength in cases involving subtle reasoning errors and complex interdependencies. Our findings suggest that leveraging these concepts of structured, hierarchical context representation combined with consensus-based objective decision-making, provides a more robust framework for error attribution in multi-agent systems.

Is the strong duality of the hard-margin SVM really trivially satisfied all the time?

It is widely known that if you were to calculate the maximizer of the dual SVM program (denote as $\alpha^*$ ), then the primal minimizer of the hard-margin SVM program, \begin{aligned}&{\underset {{w} ,\;b }{\operatorname {minimize} }}&&\|{w} \|_{2}^{2}\\&{\text{s.t.}}&&y_{i}({w} ^{\top }{x} _{i}-b)\geq 1\quad \forall i\in \{1,\dots ,N\}\end{aligned} can be found through the KKT conditions, in which case, $$w^*= \sum_{i = 1}^N \alpha^*_i y_i x_i$$ In particular, those $x_i$ corresponding to non-zero $\alpha^*_i$ are the famous support vectors. However, a technical detail that people seem to ignore is that this only holds if strong duality also holds. I struggled with verifying strong duality, so I searched widely online. Essentially, online reference argue that Slater's condition guarantees strong duality always hold for hard-margin SVM. Slater condition in this case can be written as either: There exists a pair $(w,b)$ that satisfies $y_{i}({w} ^{\top }{x} _{i}-b)> 1$ for all $i = 1, \ldots, N$ , or There exists a pair $(w,b)$ that satisfies $y_{i}({w} ^{\top }{x} _{i}-b)\geq 1$ , for all $i = 1, \ldots, N$ The latter is because the constraint functions are affine. If Slater holds, then strong duality holds and we can make the claim $$w^*= \sum_{i = 1}^N \alpha^* y_i x_i.$$ If it doesn't, then this relationship does not hold. I do not think Slater always holds despite many answers in the contrary online (virtually all of them). I suspect they are making a mistake. I think…

Mixed Methods Scenario Development for Human-Vehicle Interaction Research: A Case Study on Winter Driving

Mixed Methods Scenario Development for Human-Vehicle Interaction Research: A Case Study on Winter Driving robyn.cherinka… Wed, 11/12/2025 - 14:59 Scenarios provide a fundamental link between driving simulators and real-world conditions, shaping the extent to which the findings of a user study can be applied to public roads. However, compared to other aspects of study design, scenario development in human–vehicle interaction research tends to receive less deliberate attention. To encourage more methodical scenario generation, this work introduces a mixed methods approach for extracting representative scenarios from an integration of three real-world data sources: aggregated crash statistics, interviews with experienced drivers, and naturalistic driving data. Through a case study on winter driving, we outline the derivation of a nighttime, two-lane road scenario from these data sources and conduct an initial driving simulator pilot study to assess its realism. We hope that this demonstration of scenario generation from quantitative and qualitative data inspires researchers to consider more rigorous methods for scenario design in future work.

Yet many drivers rely on video and telemetry data to review their performance without guidance. We explore how conversational AI can support post-drive reflection by integrating LLM-generated coaching into an interactive review interface. In an exploratory within-subjects simulator study (n=16), participants completed laps under two conditions: one with video and data visualizations alone, and another with the same tools augmented with a conversational interface that provided verbal feedback after each lap. Conversational feedback supported short-term improvements in lap time, average speed, and steering control, and was rated as more useful and satisfying—though it also elicited slightly higher nervousness. These results suggest that conversational AI can make post-drive feedback more interpretable and actionable, particularly for drivers reviewing performance data in high-skill contexts like performance driving.

SAFE: Multitask Failure Detection for Vision-Language-Action Models robyn.cherinka… Wed, 11/12/2025 - 14:45 While vision-language-action models (VLAs) have shown promising robotic behaviors across a diverse set of manipulation tasks, they achieve limited success rates when deployed on novel tasks out of the box. To allow these policies to safely interact with their environments, we need a failure detector that gives a timely alert such that the robot can stop, backtrack, or ask for help. However, existing failure detectors are trained and tested only on one or a few specific tasks, while generalist VLAs require the detector to generalize and detect failures also in unseen tasks and novel environments. In this paper, we introduce the multitask failure detection problem and propose SAFE, a failure detector for generalist robot policies such as VLAs. We analyze the VLA feature space and find that VLAs have sufficient highlevel knowledge about task success and failure, which is generic across different tasks. Based on this insight, we design SAFE to learn from VLA internal features and predict a single scalar indicating the likelihood of task failure. SAFE is trained on both successful and failed rollouts, and is evaluated on unseen tasks. SAFE is compatible with different policy architectures. We test it on OpenVLA, π0, and π0-FAST in both simulated and real-world environments extensively. We compare SAFE with diverse baselines and show that SAFE achieves state-of-the-art failu…

STITCH-OPE: Trajectory Stitching with Guided Diffusion for Off-Policy Evaluation

STITCH-OPE: Trajectory Stitching with Guided Diffusion for Off-Policy Evaluation robyn.cherinka… Wed, 11/12/2025 - 14:40 Off-policy evaluation (OPE) estimates the performance of a target policy using offline data collected from a behavior policy, and is crucial in domains such as robotics or healthcare where direct interaction with the environment is costly or unsafe. Existing OPE methods are ineffective for high-dimensional, long-horizon problems, due to exponential blow-ups in variance from importance weighting or compounding errors from learned dynamics models. To address these challenges, we propose STITCH-OPE, a model-based generative framework that leverages denoising diffusion for long-horizon OPE in high-dimensional state and action spaces. Starting with a diffusion model pre-trained on the behavior data, STITCH-OPE generates synthetic trajectories from the target policy by guiding the denoising process using the score function of the target policy. STITCH-OPE proposes two technical innovations that make it advantageous for OPE: (1) prevents over-regularization by subtracting the score of the behavior policy during guidance, and (2) generates long-horizon trajectories by stitching partial trajectories together end-to-end. We provide a theoretical guarantee that under mild assumptions, these modifications result in an exponential reduction in variance versus long-horizon trajectory diffusion.

Building more accountable multi-modal LLMs through spatially-informed visual reasoning

Recent research has demonstrated that debate mechanisms among Large Language Models (LLMs) show remarkable potential for enhancing reasoning capabilities and promoting responsible text generation. However, it remains an open question whether debate strategies can effectively generalize to Multi-Modal Large Language Models (MLLMs). In this paper, we address this challenge by proposing a location-aware debate framework specifically designed for MLLMs to mitigate hallucination without requiring additional external knowledge. Our approach introduces an asymmetric debate structure across both textual and visual modalities. For textual processing, one MLLM instance generates a comprehensive image description while identifying object locations, while a second instance "zooms in" on specific regions of interest to evaluate and refine the initial descriptions. For visual processing, we introduce a novel hybrid attention module that fuses visual self-attention with cross-modal attention between textual and visual information, effectively highlighting critical content regions. The framework incorporates a judge component that evaluates the complete debate process and selects the most reliable output between the two debating instances. Our experimental results demonstrate that this approach substantially reduces hallucination across diverse MLLMs and evaluation metrics. Moreover, the framework serves as a readily integrable complement to existing hallucination mitigation methods. By emp…

Automated composition of agents: A knapsack approach for agentic component selection

Designing effective agentic systems requires the seamless composition and integration of agents, tools, and models within dynamic and uncertain environments. Most existing methods rely on static, semantic retrieval approaches for tool or agent discovery. However, effective reuse and composition of existing components remain challenging due to incomplete capability descriptions and the limitations of retrieval methods. Component selection suffers because the decisions are not based on capability, cost, and real-time utility. To address these challenges, we introduce a structured, automated framework for agentic system composition that is inspired by the knapsack problem. Our framework enables a composer agent to systematically identify, select, and assemble an optimal set of agentic components by jointly considering performance, budget constraints, and compatibility. By dynamically testing candidate components and modeling their utility in real-time, our approach streamlines the assembly of agentic systems and facilitates scalable reuse of resources. Empirical evaluation with Claude 3.5 Sonnet across five benchmarking datasets shows that our online-knapsack-based composer consistently lies on the Pareto frontier, achieving higher success rates at significantly lower component costs compared to our baselines. In the single-agent setup, the online knapsack composer shows a success rate improvement of up to 31.6% in comparison to the retrieval baselines. In multi-agent systems,…

What is generative AI? How artificial intelligence creates content

Generative AI is a kind of artificial intelligence that creates new content, including text, images, audio, and video, based on patterns it has learned from existing data. Today’s generative models are typically built on foundation-model architectures such as large-language models (LLMs) and multimodal systems, enabling them to carry on conversations, answer questions, write stories, generate code, and produce images or videos from brief prompts. Generative AI is different from discriminative AI , which draws distinctions between different kinds of input. Where discriminative AI answers questions like “Is this image of a rabbit or a lion?”, generative AI instead responds to prompts such as “Describe to me how a rabbit and lion look different from one another” or “Draw me a picture of a lion and a rabbit sitting next to each other” — and in both cases produces text or imagery that, while grounded in the AI’s training data, isn’t just a copy of something that already existed. [ Read next: Large language models: The foundations of generative AI ] Just a few years ago, generative AI was once a novelty focused on chatbots and artistic image generation. Today, it has become a core enterprise technology, and powers everything from content creation and software development to customer support and analytics workflows. But with that power comes a new set of challenges — from model alignment and hallucination to governance and data-integration hurdles. In this article, we’ll look at ho…

Building an AI Mathematician with Carina Hong - #754

In this episode, Carina Hong, founder and CEO of Axiom, joins us to discuss her work building an "AI Mathematician." Carina explains why this is a pivotal moment for AI in mathematics, citing a convergence of three key areas: the advanced reasoning capabilities of modern LLMs, the rise of formal proof languages like Lean, and breakthroughs in code generation. We explore the core technical challenges, including the massive data gap between general-purpose code and formal math code, and the difficult problem of "autoformalization," or translating natural language proofs into a machine-verifiable format. Carina also shares Axiom's vision for a self-improving system that uses a self-play loop of conjecturing and proving to discover new mathematical knowledge. Finally, we discuss the broader applications of this technology in areas like formal verification for high-stakes software and hardware.
