Google released Gemma 3n, a multimodal model for edge devices available in 2B and 4B parameter versions, with support across major frameworks like Transformers and Llama.cpp. Tencent open-sourced Hunyuan-A13B, a Mixture-of-Experts (MoE) model with 80B total parameters and a 256K context window, optimized for tool calling and coding. Black Forest Labs released FLUX.1 Kontext [dev], an open image AI model gaining rapid Hugging Face adoption. Inception AI Labs launched Mercury, the first commercial-scale diffusion LLM for chat. The FineWeb2 multilingual pre-training dataset paper was released, analyzing data quality impacts. The Qwen team released Qwen-VLo, a unified visual understanding and generation model. Kyutai Labs released a top-ranked open-source speech-to-text model running on Macs and iPhones. OpenAI introduced Deep Research API with o3/o4-mini models and open-sourced prompt rewriter methodology, integrated into LangChain and LangGraph. The open-source Gemini CLI gained over 30,000 GitHub stars as an AI terminal agent.

The LLM OS concept has evolved since 2023, with Mistral AI releasing a new Agents API that includes code execution, web search, persistent memory, and agent orchestration. LangChainAI introduced the Open Agent Platform (OAP), an open-source no-code platform for intelligent agents. OpenAI plans to develop ChatGPT into a super-assistant by H1 2025, competing with Meta. Discussions around Qwen models focus on reinforcement learning effects, while Claude 4 performance is also noted. The AI Engineer World's Fair is calling for volunteers.
o1 API, 4o/4o-mini in Realtime API + WebRTC, DPO Finetuning

OpenAI launched the o1 API with enhanced features including vision inputs, function calling, structured outputs, and a new
reasoning_effort parameter, achieving 60% fewer reasoning tokens on average. The o1 pro variant is confirmed as a distinct implementation coming soon. Improvements to the Realtime API with WebRTC integration offer easier usage, longer sessions (up to 30 minutes), and significantly reduced pricing (up to 10x cheaper with mini models). DPO Preference Tuning for fine-tuning is introduced, currently available for the 4o model. Additional updates include official Go and Java SDKs and OpenAI DevDay videos. The news also highlights discussions on Google Gemini 2.0 Flash model's performance reaching 83.6% accuracy.
