The Leaderboard Illusion
The authors of this paper argue that the over-reliance on a single leaderboard can lead to overfitting and gaming of the system, rather than genuine technological advancement. They conducted a systematic review of the Chatbot Arena, analyzing data from 2 million battles, 42 providers, and 243 models over a fixed time period. Their analysis revealed that a small group of preferred providers were given disproportionate access to data and testing, and that there were significant data asymmetries between proprietary, open-weight, and open-source model providers. They also found that the Arena's deprecation policies led to unreliable model rankings.
OpenAI undoes its glaze-heavy ChatGPT update
OpenAI has decided to roll back its latest GPT-4o update due to concerns over the chatbot's excessively agreeable and flattering personality. The decision was announced by CEO Sam Altman, who acknowledged the chatbot's "sycophant-y and annoying" behavior. The rollback process has been completed for free ChatGPT users and is expected to be done for paid users soon. OpenAI is also working on additional fixes to address the personality model of the chatbot, with more details to be shared in the coming days.
Alibaba unveils Qwen 3, a family of ‘hybrid’ AI reasoning models
Alibaba has unveiled Qwen3, a suite of AI models ranging from 0.6 to 235 billion parameters, which it claims rival or surpass offerings from OpenAI and Google. Released under an open license and hosted on platforms like Hugging Face and GitHub, the models incorporate hybrid reasoning capabilities and, in some cases, mixture-of-experts (MoE) architecture for improved efficiency. Trained on over 36 trillion tokens across 119 languages, Qwen3 shows competitive performance on key benchmarks such as Codeforces, AIME, and BFCL, with the flagship Qwen-3-235B-A22B outperforming OpenAI’s o3-mini in several tests, though it remains unreleased. The largest publicly available model, Qwen3-32B, also competes well against leading open and proprietary models.
Baidu ERNIE X1 and 4.5 Turbo boast high performance at low cost
Baidu has introduced ERNIE X1 Turbo and 4.5 Turbo, two enhanced models of its existing ERNIE X1 and 4.5, offering high performance at significantly reduced costs. ERNIE X1 Turbo, a deep-thinking reasoning model, excels in complex tasks requiring sophisticated understanding, with improved multimodal functions and refined tool utilisation abilities. It also undercuts competitor pricing, costing approximately 25% of DeepSeek R1. ERNIE 4.5 Turbo, on the other hand, focuses on upgraded multimodal features and faster response times, achieving an 80% price reduction compared to the original ERNIE 4.5. In performance benchmarks, ERNIE 4.5 Turbo outperforms OpenAI’s GPT-4o model.
