Gemini 2.5 models are now generally available, including the new Gemini 2.5 Flash-Lite, Flash, Pro, and Ultra variants, featuring sparse Mixture-of-Experts (MoE) transformers with native multimodal support. A detailed 30-page tech report highlights impressive long-horizon planning demonstrated by Gemini Plays Pokemon. The LiveCodeBench-Pro benchmark reveals frontier LLMs struggle with hard coding problems, while Moonshot AI open-sourced Kimi-Dev-72B, achieving state-of-the-art results on SWE-bench Verified. Smaller specialized models like Nanonets-OCR-s, II-Medical-8B-1706, and Jan-nano show competitive performance, emphasizing that bigger models are not always better. DeepSeek-r1 ties for #1 in WebDev Arena, and MiniMax-M1 sets new standards in long-context reasoning. Kling AI demonstrated video generation capabilities.

Anthropic's Claude 4 models (Opus 4, Sonnet 4) demonstrate strong coding abilities, with Sonnet 4 achieving 72.7% on SWE-bench and Opus 4 at 72.5%. Claude Sonnet 4 excels in codebase understanding and is considered SOTA on large codebases. Criticism arose over Anthropic's handling of ASL-3 security requirements. Demand for Claude 4 is high, with integration into IDEs and support from Cherry Studio and FastHTML. Google DeepMind introduced Gemini 2.5 Pro Deep Think and Gemma 3n, a mobile multimodal model reducing RAM usage by nearly 3x. Google's Imagen 4 Ultra ranks third in the Artificial Analysis Image Arena, available on Vertex AI Studio. Google also promoted Google Beam, an AI video model for immersive 3D experiences, and new text-to-speech models with multi-speaker support. The GAIA benchmark shows Claude 4 Opus and Sonnet leading in agentic performance.

The AI news recap highlights independent evaluations showing Grok-3 outperforming models like GPT-4.5 and Claude 3.7 Sonnet on reasoning benchmarks, while Grok-3 mini excels in reasoning tasks. Research on reinforcement learning (RL) fine-tuning reveals potential improvements for small reasoning models but also notes instability in reported gains. Benchmark results suggest Quasar Alpha and Optimus Alpha may be versions of GPT-4.1. Vision and multimodal models like Kaleidoscope, supporting 18 languages, and InternVL3, built on InternViT and Qwen2.5VL, demonstrate advances in multilingual vision and reasoning. The fusion model TransMamba combines transformer precision with speed via SSM mechanisms. Alibaba's FantasyTalking generates realistic talking portraits. Agent-focused events at CMU and tools like FilmAgent AI for virtual film production and BrowseComp benchmark for browsing agents were announced. The coding assistant Augment supports multiple IDEs with code analysis and suggestions. Discussions also covered Google’s new agent-to-agent protocol concept.
