OpenAI integrates GPT-5 into Xcode 26 with improved coding latency, though some UX trade-offs are noted. xAI's Grok Code Fast 1 gains momentum, surpassing Claude Sonnet in usage and praised for fast debugging. Zhipu's GLM-4.5 offers a cost-effective coding plan with strong performance against Claude Sonnet 4. Meituan releases the LongCat-Flash-Chat, a 560B parameter MoE model with adaptive compute and detailed technical insights. Apple debuts on-device vision-language models FastVLM and MobileCLIP2 alongside InternVL3.5.

xAI released open weights for Grok-2 and Grok-2.5 with a novel MoE residual architecture and μP scaling, sparking community excitement and licensing concerns. Microsoft open-sourced VibeVoice-1.5B, a multi-speaker long-form TTS model with streaming support and a 7B variant forthcoming. Motif Technology published a detailed report on Motif-2.6B, highlighting Differential Attention, PolyNorm, and extensive finetuning, trained on AMD MI250 GPUs. In coding tools, momentum builds around GPT-5-backed workflows, with developers favoring it over Claude Code. Alibaba released Qwen-Code v0.0.8 with deep VS Code integration and MCP CLI enhancements. The MCP ecosystem advances with LiveMCP-101 stress tests, the universal MCP server "Rube," and LangGraph Platform's rollout of revision queueing and ART integration for RL training of agents.
Grok 4: xAI succeeds in going from 0 to new SOTA LLM in 2 years

xAI launched Grok 4 and Grok 4 Heavy, large language models rumored to have 2.4 trillion parameters and trained with 100x more compute than Grok 2 on 100k H100 GPUs. Grok 4 achieved new state-of-the-art results on benchmarks like ARC-AGI-2 (15.9%), HLE (50.7%), and Vending-Bench, outperforming models such as Claude 4 Opus. The model supports a 256K context window and is priced at $3.00/M input tokens and $15.00/M output tokens. It is integrated into platforms like Cursor, Cline, LangChain, and Perplexity Pro/Max. The launch was accompanied by a controversial voice mode and sparked industry discussion about xAI's rapid development pace, with endorsements from figures like Elon Musk and Arav Srinivas.

HuggingFace released SmolLM3-3B, a fully open-source small reasoning model with open pretraining code and data, marking a high point in open source models until Olmo 3 arrives. Grok 4 was launched with mixed reactions, while concerns about Claude 4 nerfs and an imminent Claude 4.1 surfaced. Gemini Nano is now shipping in Chrome 137+, enabling local LLM access for 3.7 billion users. Tencent introduced Hunyuan-A13B, an 80B parameter model with a 256K context window running on a single H200 GPU. The Gemini API added a batch mode with 50% discounts on 2.5 models. MatFormer Lab launched tools for custom-sized Gemma 3n models. Open source OCR models like Nanonets-OCR-s and ChatDOC/OCRFlux-3B derived from Qwen2.5-VL-3B were highlighted, with licensing discussions involving Alibaba.
