xAI launched Grok 4.1, achieving a #1 rank on the LM Arena Text Leaderboard with an Elo score of 1483, showing improvements in creative writing and anti-hallucination. OpenAI's GPT-5.1 "Thinking" demonstrates efficiency gains with ~60% less "thinking" on easy queries and strong ARC-AGI performance. Google DeepMind released WeatherNext 2, an ensemble generative model that is 8× faster and more accurate for global weather forecasts, integrated into multiple Google products. Sakana AI raised ¥20B ($135M) in Series B funding at a $2.63B valuation to focus on efficient AI for resource-constrained enterprise applications in Japan. New evaluations highlight tradeoffs between hallucination and knowledge accuracy across models including Claude 4.1 Opus and Anthropic models.
$100k to predict LMSYS human preferences in a Kaggle contest

Llama 3 models are making breakthroughs with Groq's 70B model achieving record low costs per million tokens. A new Kaggle competition offers a $100,000 prize to develop models predicting human preferences from a dataset of over 55,000 user-LLM conversations. Open source evaluator LLMs like Prometheus 2 outperform proprietary models such as GPT-4 and Claude 3 Opus in judgment tasks. New datasets like WildChat1M provide over 1 million ChatGPT interaction logs with diverse and toxic examples. Techniques like LoRA fine-tuning show significant performance gains, and NVIDIA's NeMo-Aligner toolkit enables scalable LLM alignment across hundreds of GPUs. Factuality-aware alignment methods are proposed to reduce hallucinations in LLM outputs.
