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.
OpenEvidence, the ‘ChatGPT for doctors,’ raises $250m at $12B valuation, 12x from $1b last Feb

OpenEvidence raised $12 billion, a 12x increase from last year, with usage by 40% of U.S. physicians and over $100 million in annual revenue. Anthropic released a new Claude model constitution under CC0 1.0, framing it as a living document for alignment and training. Podium reported over $100 million ARR from 10,000+ AI agents, shifting from software sales to AI operators. Innovations in agent memory and reliability include the Agent Cognitive Compressor (ACC) and multi-agent scientific workflows via MCP-SIM. Agentic benchmarking shows challenges in long-horizon tasks with models like Gemini 3 Flash High, GPT-5.2 High, and Claude Opus 4.5 High scoring modestly on professional services and legal research benchmarks.

Anthropic released Claude Haiku 4.5, a model that is over 2x faster and 3x cheaper than Claude Sonnet 4.5, improving iteration speed and user experience significantly. Pricing comparisons highlight Haiku 4.5's competitive cost against models like GPT-5 and GLM-4.6. Google and Yale introduced the open-weight Cell2Sentence-Scale 27B (Gemma) model, which generated a novel, experimentally validated cancer hypothesis, with open-sourced weights for community use. Early evaluations show GPT-5 and o3 models outperform GPT-4.1 in agentic reasoning tasks, balancing cost and performance. Agent evaluation challenges and memory-based learning advances were also discussed, with contributions from Shanghai AI Lab and others. "Haiku 4.5 materially improves iteration speed and UX," and "Cell2Sentence-Scale yielded validated cancer hypothesis" were key highlights.
