The rapid proliferation of AI chatbots has made it difficult to know which models are actually improving and which are falling behind. Traditional academic benchmarks only tell you so much, which has led many to lean on vibes-based analysis from LM Arena. However, a new study claims this popular AI ranking platform is rife with unfair practices, favoring large companies that just so happen to rank near the top of the index. The site's operators, however, say the study draws the wrong conclusions

A new paper from AI lab Cohere, Stanford, MIT, and Ai2 accuses LM Arena, the organization behind the popular crowdsourced AI benchmark Chatbot Arena, of helping a select group of AI companies achieve better leaderboard scores at the expense of rivals. According to the authors, LM Arena allowed some industry-leading AI companies like Meta, OpenAI, Google, and Amazon to privately test several variants of AI models, then not publish the scores of the lowest performers. This made it easier for thes

Separating AI reality from hyped-up fiction isn’t always easy. That’s why we’ve created the AI Hype Index—a simple, at-a-glance summary of everything you need to know about the state of the industry. AI agents are the AI industry’s hypiest new product—intelligent assistants capable of completing tasks without human supervision. But while they can be theoretically useful—Simular AI’s S2 agent, for example, intelligently switches between models depending on what it’s been told to do—they could al

April 19, 2025 nullprogram.com/blog/2025/04/19/ An early, small hurdle diving into WebAssembly was allocating my allocator. On a server or desktop with virtual memory, the allocator asks the operating system to map fresh pages into its address space (sbrk, anonymous mmap, VirtualAlloc), which it then dynamically allocates to different purposes. In an embedded context, dynamic allocation memory is typically a fixed, static region chosen at link time. The WASM execution environment more resemble

AI labs are increasingly relying on crowdsourced benchmarking platforms such as Chatbot Arena to probe the strengths and weaknesses of their latest models. But some experts say that there are serious problems with this approach from an ethical and academic perspective. Over the past few years, labs including OpenAI, Google, and Meta have turned to platforms that recruit users to help evaluate upcoming models’ capabilities. When a model scores favorably, the lab behind it will often tout that sc

Even though I am a C++ programmer at heart, Go fascinates me for none of the reasons you think. Go has made several interesting design decisions: It has virtually no Undefined Behavior. It has very simple GC semantics that they’re mostly stuck with due to design decisions in the surface language. These things mean that despite Go having a GC, it’s possible to do manual memory management in pure Go and in cooperation with the GC (although without any help from the runtime package). To demonstra

When programming in Odin you can use arena allocators. If you use an arena allocator combined with a dynamic array, then there are a couple of pitfalls that may not be apparent at first. Let’s look at what arenas are, how you can run into trouble when naively using them with dynamic arrays and what you can do instead. What’s an arena? How does it work?# Arenas and arena allocators are useful for grouping allocations that have the same lifetime. Here lifetime means allocations that are fine to

Earlier this week, Meta landed in hot water for using an experimental, unreleased version of its Llama 4 Maverick model to achieve a high score on a crowdsourced benchmark, LM Arena. The incident prompted the maintainers of LM Arena to apologize, change their policies, and score the unmodified, vanilla Maverick. Turns out, it’s not very competitive. The unmodified Maverick, “Llama-4-Maverick-17B-128E-Instruct,” was ranked below models including OpenAI’s GPT-4o, Anthropic’s Claude 3.5 Sonnet, a

Meta cheated on an AI benchmark, and that is hilarious. According to Kylie Robison at The Verge the suspicions started percolating after Meta released two new AI models based on its Llama 4 large language model over the weekend. The new models are Scout, a smaller model intended for quick queries, and Maverick, which is meant to be a super efficient rival to more well-known models like OpenAi’s GPT-4o (the harbinger of our Miyazaki apocalypse). In the blog post announcing them, Meta did what ev

One of the new flagship AI models Meta released on Saturday, Maverick, ranks second on LM Arena, a test that has human raters compare the outputs of models and choose which they prefer. But it seems the version of Maverick that Meta deployed to LM Arena differs from the version that’s widely available to developers. As several AI researchers pointed out on X, Meta noted in its announcement that the Maverick on LM Arena is an “experimental chat version.” A chart on the official Llama website, me
