A breakthrough way to estimate closed-source LLM parameter sizes — no access to model weights, just black-box API calls! 🕵️‍♂️ Insight from Zhihu Contributor 李博杰 @bojie_li 🔑Core Insight Closed labs hide model sizes, but they can’t hide what models know. Inference can be compressed, factual knowledge cannot — this is the key to estimating LLM scale. 📅3-Year Long Test My friends He Jiyan & Zheng Zihan asked top models the same question for 3 years: "Do you know USTC Hackergame?" (A classic CTF contest) • May 2024: GPT-4o made up fake problems • Feb 2025: Claude 3.7 Sonnet listed 19 real 2023 challenges • Apr 2026: Frontier models recall full problems across multiple years 🧪IKP: Incompressible Knowledge Probes After DeepSeek-V4 launch, my agent spent 4 days building IKP: • 1,400 questions 7 rarity levels • Tested on 188 models from 27 vendors 📊Finding 1: Factual Accuracy = LLM Scale Indicator Factual accuracy ↔ log(parameter size) (log-linear correlation) R² = 0.917 (89 open-source models: 135M ~ 1.6T params) Closed-source estimates (90% CI: 0.3–3x): • GPT-5.5 ≈ 9T | Claude Opus 4.7 ≈ 4T • GPT-5.4 ≈ 2.2T | Claude Sonnet 4.6 ≈ 1.7T • Gemini 2.5 Pro ≈ 1.2T 📚 Finding 2: Impact > Citation Count Citation count & h-index can’t predict if a model recognizes a researcher. Models remember people with impactful work, not those with massive incremental papers. 📈 Finding 3: Factual Capacity Doesn’t Compress Over Time Tested 96 open-source models across 3 years — IKP time coefficient = 0 (p < 10⁻¹⁵), rejecting Densing Law’s 0.0117/month prediction. 💡Benchmarks saturate, but factual knowledge grows with parameters. 🎯Key Takeaway Black-box LLM scale is no longer a secret — factual knowledge is the ultimate probe. 🔗Full article: zhihu.com/pin/20327696850123… #LLM #ModelScale #DeepSeek #GPT5 #AIResearch

A miniature landscape stretches out beneath her like a detailed model world as she moves through it effortlessly. 🌿👠 @IAMKELLYBROOK walks through the scene in a black bikini and heels, her presence turning rivers, roads, and hills into delicate, toy-like features beneath each step. Calm, poised, and impossibly scaled against the tiny environment around her. #giantess #aiart #aivideo #sizetwitter #kellybrook #giantwoman #megagiantess #miniatureworld #scale #highheels #stilettos #shoefetish #cinematicai #vfx #modelscale #fantasyart #towering #landscape #sizecontrast

Now that your setup is ready, it’s time to build. • Open your project folder in Cursor (or any editor). • Inside index.ts, you’ll see the entry point of your game. • Create an entity, think of it like a character, NPC, or object: Basically copy this “const spider = new Entity({ modelUri: 'models/npcs/spider.gltf', modelScale: 2.5,}); spider.spawn(world, { x: 0, y: 3, z: -15 });” • Save, refresh your HYTOPIA client, and you’ll see your spider come alive 🕷️. From here, you can start adding collisions, movement, and game logic, all through the HYTOPIA SDK.

Evolución del trabajo en Yamaha R1 #tamiya #yamaha #R1 #modelscale

He terminado la R1 "tandera" que he recuperado. Me ha costado encajar el carenado, ya que no lo pude desmontar por miedo a romperlo. El caso es que hay otra pieza restaurada y recuperada de la basura. #tamiya #yamaha #R1 #modelscale #modeler

Con la instalación de las horquillas delanteras, cuadro de relojes y el cableado, terminamos con el montaje de la parte mecánica. Siguiente paso, la carrocería. #tamiya #R1 #yamaha #modelscale #modeler

El siguiente paso era instalar los escapes y los radiadores, junto con la tubería. Es un kit que me está sorprendiendo porque todo encaja a la perfección. #tamiya #R1 #yamaha #modelscale #models

He recortado el silencioso de la R1 de circuito. Lo hice más corto, ya que el de la versión de calle es tocho y largo. Las calcas d fibra de la maqueta nueva me han dado el primer problemilla y es que se cuartean😖 #tamiya #R1 #yamaha #modelscale

Una vez anclado el motor al chasis, se monta el basculante trasero. Ha sido una operación sin complicaciones para mi sorpresa. En algunos modelos, suele ser complicado. #tamiya #yamaha #R1 #modelscale

Los discos se han perforado con una broca 0'7 A uno de los basculantes, se le ha forrado el guardapolvo con calca de fibra, para una versión R1 de circuito. Basculantes traseros acabados. #tamiya #yamaha #R1 #modelscale

He terminado la recuperación de la NR. La idea era mostrar la parte trasera de la moto más estilizada. Con un estilo "endurance" claro, homenajeando a las VFR-RC de Honda. Espero que os guste. #tamiya #NR #honda #modelscale

Growing up on an Ohio dairy farm, Mark Jones says he avoided milking cows whenever possible, always loved machinery, and especially enjoyed seeing scale model tractors at farm shows. #tractor #modelscale #Cockshutt #farmer farmshow.com/a_article.php?a…
