Adding Up to Nothing: Coarse Reasoning and the Vanishing St. Petersburg Paradox

The St. Petersburg paradox has long been a thorn in the side of rational decision theory. Offering an infinite expected payout but consistently eliciting modest real-world bids, the game exposes a rift between mathematical expectation and human judgment. Most solutions dodge this by modifying utility functions, imposing discounting, or resorting to exotic number systems. But what if we change the addition itself? ...

Learning to Struggle: Teaching LLMs to Code Like Real Students

What makes code feel like it was written by a student? Not just errors, but how they evolve. Not just style, but how it diverges from the polished norms. This week’s standout paper, ParaStudent, tackles a refreshingly underexplored challenge: teaching LLMs to generate code that learns like a student — messy, iterative, full of hiccups and growth. Instead of building yet another high-performing code assistant, the authors fine-tune LLMs to mimic real students in an introductory CS class at UC Berkeley. They call their framework ParaStudent. The goal: replace idealized solutions with something plausibly human — an LLM that stumbles, recovers, and grows in fidelity to how novices actually write code. ...

The Debugger Awakens: Why Kodezi Chronos Leaves GPT-4 in the Dust

When it comes to software development, coding is optional — debugging is inevitable. And yet, most AI code tools today act like overconfident interns: quick to suggest, but clueless when the system breaks. Kodezi Chronos flips that script. Instead of trying to stretch token windows to a million and hoping for the best, Chronos builds an entirely new foundation for debugging: persistent memory, adaptive retrieval, and autonomous iteration. Beyond Token Stuffing: Why Context Windows Miss the Point Large Language Models like GPT-4 and Claude 3 boast massive context windows — 128K, 200K, even a million tokens. But real-world debugging rarely needs to read the whole repository at once. It needs to find the right needle in a messy, multi-decade haystack, then trace its thread through historical commits, CI logs, and edge-case test failures. ...

When to Speak, When to Stay Qubit: How Sporadic Updates Tame Quantum Noise

If quantum computing is the future, then quantum federated learning (QFL) is its decentralized heartbeat — promising data privacy, distributed intelligence, and unparalleled computing power. But like a high-performance car with faulty brakes, QFL’s potential is hindered by one chronic issue: quantum noise. A new paper introduces a deceptively simple yet powerful idea to address it — sporadic learning. In doing so, it doesn’t just offer a technical tweak — it reframes how we think about contribution and silence in distributed AI. ...

Fine-Tuning Isn’t Just Supervised: Why SFT Is Really RL in Disguise

In the arms race to align large language models (LLMs), supervised fine-tuning (SFT) and reinforcement learning (RL) are often painted as competing paradigms. SFT is praised for its stability and simplicity; RL is heralded for its theoretical soundness and alignment fidelity. But what if this dichotomy is an illusion? A recent preprint from Chongli Qin and Jost Tobias Springenberg makes a bold and elegant claim: SFT on curated data is not merely supervised learning—it is actually optimizing a lower bound on the RL objective. ...

Red Flag on the Track: Why LLMs Still Struggle with Real Algorithmic Reasoning

In the world of AI benchmarks, most roads lead to flashy competitions: solving coding puzzles, climbing Codeforces ratings, or passing Olympiad-level problems. But a new benchmark — FormulaOne — changes the race. It doesn’t ask, “Can you win a medal?” It asks, “Can you think like a researcher?” And the answer from today’s frontier LLMs? A resounding no. From Codeforces Champs to Research Rookies The authors of FormulaOne strip away the glitz of competitive programming and delve into something far more consequential: research-grade algorithmic problems grounded in Monadic Second-Order (MSO) logic over graphs. These aren’t out-of-distribution visual puzzles like ARC. They’re in-distribution, theoretically tractable problems designed with precision to demand multi-step symbolic reasoning, mathematical insight, and clean implementation. ...

Sketching a Thought: How Mental Imagery Could Unlock Autonomous Machine Reasoning

From Reaction to Reflection Modern AI models, especially language models, are stunningly capable at answering our queries. But what happens when there is no query? Can an AI reason about the world not just in reaction to prompts, but proactively — triggered by internal goals, simulated futures, and visual imagination? That’s the central question Slimane Larabi explores in his latest paper: “Can Mental Imagery Improve the Thinking Capabilities of AI Systems?” ...

Train of Thought: How Long-Haul RL Unlocks LLM Reasoning Diversity

In the race to make Large Language Models (LLMs) reason like humans—or better—most researchers obsess over one thing: prompting. Chain-of-thoughts, few-shot demos, scratchpads, tools. But a new study from NVIDIA suggests something even more fundamental: it’s not just how you prompt them—it’s how long you train them. Their paper, Scaling Up RL: Unlocking Diverse Reasoning in LLMs via Prolonged Training, explores how stretching reinforcement learning (RL) over time unlocks broader, more stable, and more versatile reasoning in LLMs. This isn’t just about incremental gains—it’s about escaping reasoning ruts. ...

Beyond Search: RAG’s Awakening to Enterprise Spreadsheets

Retrieval-Augmented Generation (RAG) systems are fast becoming the connective tissue between Large Language Models (LLMs) and real-world business data. But while RAG systems excel at fetching relevant passages from documents, they often stumble when the data isn’t narrative but numerical. In enterprise environments, where structured formats like HR tables, policy records, or financial reports dominate, this mismatch has become a bottleneck. The paper “Advancing Retrieval-Augmented Generation for Structured Enterprise and Internal Data” by Chandana Cheerla proposes a much-needed upgrade: a RAG system that treats structured and tabular data as first-class citizens. It doesn’t just flatten tables into linear strings or hope LLMs can reason through semi-garbled inputs. It restructures the entire RAG pipeline to respect and preserve the meaning of tables, rows, and metadata. ...

Pricing Plans, Meet Prompt Engineering: LLMs and the Future of SaaS Monetization

It’s no secret that SaaS pricing pages are often a tangled mess of human-made tables, unclear add-ons, and marketing jargon masquerading as feature distinctions. What was once a differentiator—flexible, modular pricing—is now a liability for scale. In this increasingly complex landscape, a new concept is emerging: intelligent pricing (or iPricing), where SaaS pricing becomes a machine-readable, dynamically evolving artifact. The paper “From Static to Intelligent: Evolving SaaS Pricing with LLMs” by Cavero et al. proposes a concrete path toward this transformation. At its core is AI4Pricing2Yaml, an LLM-driven pipeline that scrapes, parses, and restructures SaaS pricing pages into a standardized YAML format. This isn’t just about scraping HTML; it’s about turning pricing into a software component—one that can be audited, version-controlled, and analyzed like any other part of the stack. ...
