xAI released Grok 4.3, improving cost/performance with a 53 Intelligence Index score, 4 points higher than Grok 4.20, and significant gains on GDPval-AA and τ²-Bench Telecom. However, accuracy tradeoffs raised reliability concerns. Community opinions are mixed, with some praising token-efficiency and others noting regressions and pricing concerns. DeepSeek V4 Pro emerges as a leading open-weight coding/agent model, comparable to Codex and Claude Code, featuring a 1M context window and efficient attention mechanisms. Benchmarking shows open-weight models like Kimi K2.6, MiMo V2.5 Pro, and DeepSeek V4 Pro closing the gap with closed models such as Gemini 3.1 Pro Preview, Claude Opus 4.7, and GPT-5.5. DeepSeek's multimodal efforts focus on explicit spatial grounding with a novel "point while thinking" approach using DeepSeek-ViT and CSA compression.

DeepSeek-V4 technical release features a 1.6T-parameter MoE with 49B active parameters and 1M-token context, showcasing hybrid attention and compressed KV schemes for major memory reductions. It ranks as the #2 open-weights reasoning model behind Kimi K2.6 but has a high hallucination rate and higher serving costs. Hardware-model co-design is emphasized, with NVIDIA Blackwell Ultra delivering 150+ TPS/user and support for FP4 and FP8 quantization enabling deployment on single nodes. Positioning among open Chinese models is competitive with GLM-5.1 and Xiaomi MiMo V2.5 Pro. Meanwhile, OpenAI launched GPT-5.5 and GPT-5.5 Pro APIs with a 1M context window, focusing on improved long-running workflows and token efficiency, quickly integrated into tools like GitHub Copilot and Cursor. "GPT-5.5 handles complex, tool-heavy, ambiguous workflows with fewer retries," highlighting rapid distribution and agent integration.
