OpenAI banned a batch of accounts that used AI to generate articles, posts, and fake interactions to influence the 2024 presidential election in Ghana.
Mistral AI has released Mistral Small 3, a 24-billion-parameter large language model licensed under Apache 2.0, focusing on low latency and local deployment; it achieves 81% accuracy on MMLU.
PyTorch 2.6.0 has been officially released. Major updates include: torch.compile supports Python 3.13; a new torch.compiler.set_stance API dynamically controls compilation behavior.
Hugging Face has released Open-R1, a fully open-source reproduction of DeepSeek-R1.
DeepSeek has released a new model, DeepSeek-R1, which can be invoked by specifying model=deepseek-reasoner; official links for update notes and invocation guides are provided.
Text Generation Inference adds support for two inference backends: TRT-LLM and vLLM.
Mistral AI has released Codestral 25.01, which features a more efficient architecture and an improved tokenizer compared to Codestral-2405, achieving approximately 2x faster code generation and completion speeds.
The deepseek-chat model has been upgraded to DeepSeek-V3. Continue using model=deepseek-chat when making calls; the interface remains unchanged. For detailed updates, see the official DeepSeek-V3 release page.
OpenAI released the o1 model and introduced developer-focused tools including improvements to the Realtime API and a new fine-tuning method.
The deepseek-chat model has been upgraded to DeepSeek-V2.5-1210. Mathematical capabilities improved from 74.8% to 82.8% on the MATH-500 benchmark, and coding accuracy increased from 29.2% to 34.38% on LiveCodebench (08.01 - 12.01). Chinese writing and reasoning capabilities also showed improvements in internal test sets, along with optimizations to file upload and web page summarization features.
OpenAI's video generation model Sora is now live at sora.com, supporting videos up to 1080p resolution and 20 seconds in length, compatible with widescreen, vertical, and square aspect ratios; users can generate new content from text or import their own materials for extension, remixing, and blending.
Hugging Face and the cross-institutional project LLM-jp jointly released the Open Japanese LLM Leaderboard. It includes over 20 Japanese datasets covering 16 tasks (including NLI, machine translation, code generation, mathematical reasoning, multi-hop question answering, etc.), uses llm-jp-eval v1.14.1 for evaluation, and is backed by vLLM v0.6.3 and Japan's high-performance computing platform mdx. The leaderboard supports automatic model deployment and evaluation, with all datasets and tools being open source.
Hugging Face introduces the LayerSkip method in a blog post, proposing self-speculative decoding, which uses early layers of the same LLM to generate draft tokens and deeper layers for verification. This approach requires training with layer dropout and early exit loss.
Hugging Face announced the introduction of a new storage solution based on Content-Defined Chunking (CDC) for the Hugging Face Hub. By uploading and storing only modified byte chunks, it significantly improves storage efficiency and iteration speed.
Hugging Face, in collaboration with Atla, launched the Judge Arena platform, which supports user evaluation of 18 mainstream large language models (including GPT-4o, Claude 3.5 Sonnet.
Playwright v1.49.0 has been released, featuring the new expect(locator).toMatchAriaSnapshot() assertion for verifying page accessibility trees, with support for generation via Test Generator and updates using --update-snapshots; it introduces a new Chromium headless mode ('chromium' channel) that more closely mimics real browser behavior; the test runner adds tsconfig configuration, test.fail.only(), multiple globalSetup/Teardown functions, screenshot='on-first-failure', and other features; HTML reports include previous/next navigation buttons; traces support grouping; Docker images are upgraded to Node.js v22 LTS; includes Chromium 131 / Firefox 132 / WebKit 18.2.
Mistral AI officially announced the launch of multiple new features for le Chat (all in beta): support for web search with citations; a new Canvas interface for collaborative creation and inline editing; integration of the Pixtral Large multimodal model for deep understanding of documents and images; connection to Black Forest Labs' Flux model for high-quality image generation; and the introduction of reusable, shareable Agent features to automate repetitive workflows. All features are currently available for free.
Mistral AI released Pixtral Large, a 124B open-weight multimodal model built on Mistral Large 2, featuring a 123B multimodal decoder and a 1B vision encoder.
Mistral has released the Batch API, available on La Plateforme. It processes high-concurrency requests at 50% lower cost than the synchronous API, supporting use cases such as customer feedback analysis, bulk document summarization and translation, vector embeddings, and data annotation. Each workspace is limited to 1 million in-progress requests. The service will soon be available on cloud provider partner platforms.
Mistral AI has released a content moderation API, sharing the same source as Le Chat's built-in moderation service. It supports two input endpoints for raw text and conversational content. The model is a multilingual LLM classifier covering 11 languages including Arabic, Chinese, and English. It identifies inappropriate content across 9 policy categories and provides protection against model-generated harms such as unqualified advice and PII leakage.
Hugging Face officially released a PyCharm integration plugin that supports right-click model insertion (e.g., microsoft/Phi-3.5-vision-instruct), real-time model card viewing, and local cache management; this feature is exclusive to PyCharm Professional, and users can obtain a 3-month free subscription using the code PyCharm4HF.
Argilla 2.4 introduces a feature that allows users to build fine-tuning and evaluation datasets on Hugging Face Hub without coding. It supports one-click import from any public Hub dataset, automatic generation of initial configurations, definition of questions, and real-time preview. Users can complete annotation, scoring, ranking, and other feedback collection tasks via the UI.
OpenAI has launched a ChatGPT search feature that provides fast, timely answers accompanied by relevant web links.
Hugging Face and Intel Labs jointly proposed Universal Assisted Generation (UAG), utilizing a bidirectional tokenizer translation mechanism.
