OpenAI rapidly expanded the GPT-5.5 family with multiple variants including gpt-image-2, GPT-5.5 Pro, and GPT-5.5 Cyber, receiving positive feedback for efficiency and usability. Codex evolved into a long-running agent runtime with a new /goal mechanism, achieving 61% success on ARC-AGI-3 games after extensive testing. OpenAI also introduced cybersecurity-focused models like GPT-5.5-Cyber targeting enterprise and government sectors. Meanwhile, Zyphra released the open-model ZAYA1-74B-Preview, a 74B parameter mixture-of-experts model trained on AMD hardware under Apache 2.0 license, alongside a vision-language model ZAYA1-VL-8B. Inference infrastructure competition intensified with vLLM updates improving throughput and latency, including support for DeepSeek V4 and enhanced quantization/backends.

OpenAI's GPT-5.5 achieves top-tier performance in long-horizon cyber tasks, matching or surpassing Claude Mythos Preview with a 71.4% pass rate and showing ongoing improvement beyond 100M tokens inference. OpenAI also released an Advanced Account Security update for ChatGPT enhancing phishing resistance. The Codex update expands beyond coding to general computer tasks, improving speed by up to 42% and introducing role-based onboarding and app integrations. Economically, GPT-5.5 Pro shows a slight SOTA improvement on CritPt with ~60% lower cost and token use compared to GPT-5.4 Pro. In open-weight models, Qwen3.6 27B leads under 150B parameters with an Intelligence Index score of 46, featuring 262K context, native multimodal input, and efficient BF16 weights. Tencent's Hy3-preview (295B total, 21B active MoE) scores 42 on the Intelligence Index with strong scientific reasoning on CritPt. xAI's Grok 4.3 shows sharp improvements on agentic benchmarks with reduced cost.

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.

OpenAI launched GPT-5.5 as its new flagship model for "real work and powering agents," immediately available in ChatGPT and Codex but with delayed API access due to enhanced safety requirements. The model features improved token efficiency and supports longer multi-step execution with tool use and self-checking. Pricing is set at $5/$30 per million tokens for GPT-5.5 and $30/$180 for GPT-5.5 Pro, roughly double the cost of GPT-5.4. The release includes significant Codex upgrades such as browser control, document handling, and OS-wide dictation. Early reactions are mixed but generally positive, noting improvements in coding and long-horizon tasks, though some benchmarks show incremental gains and hallucination issues persist. Third-party ecosystem support like Hermes Agent integration appeared quickly.
