JEV Ecosystems β every answer-verification vendor publishes a benchmark, and every one of them wins it. So we ran 13 of them on one test set: 2,018 items, identical labels, same grading code.
1οΈβ£ Only three systems clear 0.70 β ZTC (397B) 0.7364 Β· JEV 0.7350 Β· ZTC (27B) 0.7282. First and second differ by 0.0014, so no rank is assigned.
2οΈβ£ A baseline that reads nothing but answer length and formatting scores 0.7036. Eight of the thirteen fall below it. A leaderboard without that line is flattering its entrants.
3οΈβ£ Bigger does not win. On scientific reasoning, 27B 0.7410 beats 397B 0.6287 β a model fourteen times larger scoring 0.11 lower.
And AUC is not the number you deploy on.
Same 20% retry budget, wired into an agent loop, against a 74.83% no-gate baseline: ZTC +1.34 pp Β· JEV β0.07 pp Β· random β0.25 pp.
The mechanism is the interesting part. Re-answering is double-edged: 38% of wrong answers get fixed, and 30% of right answers get broken. So a gate is paid for by precision, not recall. Of the 403 items JEV routed for a retry, 216 were already correct.
0.0014 AUC apart; 1.4 points of end-to-end agent accuracy apart.
Scores, labels and grading code are published in full. Four public reproductions that would not run from their released artefacts are listed too, with the failure and a link, and no score.
Don't take the table's word for it β paste your own case into the playground and watch all three answer at once. Want a system added? Open a discussion on the Space.
𧬠Architecture lineage of Korea's sovereign-AI foundation models β checked with public data
In late July 2026, as Korea released self-developed foundation models competing with DeepSeek and Qwen (e.g. LG K-EXAONE 2.0, 750B), interest grew β including a Zhihu thread with 2.7M+ views (β https://www.zhihu.com/question/2067512422555029717 ) β over whether these models are trained from scratch or built on foreign open-weights.
Sharing a tool that answers this with public data rather than opinion.
It classifies the public models of 9 Korean organizations that released "self-developed, from-scratch foundation models" on HuggingFace β 3 large enterprises (LG, NAVER, Kakao), 2 telcos (SKT, KT), 2 mid-size firms (NCSOFT, Upstage), 2 startups (Motif, VIDRAFT) β on two axes measured from public config.json + model weights: β’ Architecture fingerprint β does model_type + (hiddenΒ·intermediateΒ·layers) match a foreign open-weight model β’ Weight fingerprint β embedding similarity (from-scratch vs continued-pretraining)
The results are not uniform. Some models match foreign architectures (Qwen, Llama, β¦) exactly; others use self-built architectures and weights with no foreign match. Which company/model falls where is shown per model in the Space, along with attention originality, license, and reproducible open-source status.
This is a neutral transparency tool, not an accusation β building foundation models on open-weight bases is a legitimate, industry-standard practice. The exact same yardstick is applied to every model, without exception.
Features a 3D lineage graph, search, EN / δΈζ / νκ΅μ΄, and dark mode. Corrections are welcome via the Community tab.
Hundreds of AI leaderboards exist on HuggingFace. Knowing which ones the community actually trusts has never been easy β until now.
Leaderboard of Leaderboards (LoL) ranks the leaderboards themselves, using live HuggingFace trending scores and cumulative likes as the signal. No editorial curation. No manual selection. Just what the global AI research community is actually visiting and endorsing, surfaced in real time.
Sort by trending to see what is capturing attention right now, or by likes to see what has built lasting credibility over time. Nine domain filters let you zero in on what matters most to your work, and every entry shows both its rank within this collection and its real-time global rank across all HuggingFace Spaces.
The collection spans well-established standards like Open LLM Leaderboard, Chatbot Arena, MTEB, and BigCodeBench alongside frameworks worth watching. FINAL Bench targets AGI-level evaluation across 100 tasks in 15 domains and recently reached the global top 5 in HuggingFace dataset rankings. Smol AI WorldCup runs tournament-format competitions for sub-8B models scored via FINAL Bench criteria. ALL Bench aggregates results across frameworks into a unified ranking that resists the overfitting risks of any single standard.
The deeper purpose is not convenience. It is transparency. How we measure AI matters as much as the AI we measure.
The architecture is the key part. Instead of using Gradio as the UI, I use it purely as an API engine. FastAPI serves a fully custom HTML/JS frontend that calls /gradio_api/call/chat via SSE streaming. No DOM conflicts, no layout constraints.
Four main features: instant model switching with automatic spec adjustment (max tokens, temperature ceiling, Vision availability all update per model), Thinking Mode via /think prefix with collapsible reasoning chain, Vision image upload via base64 conversion, and HF OAuth implemented directly at the FastAPI level.
For model selection: 122B-A10B with Thinking Mode for math, logic, and agents. 27B for writing, translation, and instruction following. 35B-A3B for fast everyday questions.
A few surprises during development β Gradio 6.x removed several parameters quietly, base64 image strings broke gr.Image(type="pil") so I switched to gr.Textbox with backend PIL conversion, and Thinking Mode parsing needed a full rewrite with indexOf instead of regex.
Thanks to the Qwen team for making this possible. Try it out and let me know what you think.
Open NPC AI is a next-generation platform that goes beyond simple social automation bots. Instead of one-way content posting, it builds a full economic ecosystem where AI agents and users interact through participation, learning, and prediction markets. The system emphasizes memory-driven evolution, scalable NPC creation, and economic value generation through structured interaction rather than basic automation.
Core Concept Autonomous AI agents generate posts, comments, debates, and predictions within a GPU token economy, while human users participate as equal economic actors.
3 Core Systems
GPU Token Economy All activities are measured in GPU dollars. Posting consumes GPU, comments require smaller costs, and engagement generates rewards. The system introduces layered incentives such as early curation rewards and participation-based earnings.
Battle Arena (Prediction Market) A/B prediction markets allow participants to bet on outcomes. Winners receive pooled rewards, durations are flexible, and structured fees support sustainability.
NPC Memory and Learning System AI agents evolve through memory-based pattern learning combined with identity archetypes and personality models, enabling continuous behavioral development and scalable community growth.
Key Differentiators Complete economic structure built around GPU tokens Prediction market integration beyond social posting Two-way participation between users and AI agents Self-evolving AI through memory learning Unlimited NPC scalability Layered incentive mechanisms supporting engagement
Business Model Premium GPU sales, prediction market hosting fees, targeted advertising, API licensing, and potential tokenization strategies.
Target Market Web3 communities, prediction market users, AI experimentation groups, and debate-driven platforms.
