Anthropic announces a new CTO. Frontier coding agents see updates with Claude Sonnet 4.5 showing strong cybersecurity and polished UX but trailing GPT-5 Codex in coding capability. xAI Grok Code Fast claims higher edit success at lower cost. Google's Jules coding agent launches a programmable API with CI/CD integration. Qwen clarifies its model taxonomy and API tiers. Vision/LM Arena rankings show a tight competition among Claude Sonnet 4.5, Claude Opus 4.1, Gemini 2.5 Pro, and OpenAI's latest models. In video generation, Sora 2 Pro leads App Store rankings with rapid iteration and a new creator ecosystem; early tests show it answers GPQA-style questions at 55% accuracy versus GPT-5's 72%. Video Arena adds new models like Luma's Ray 3 and Kling 2.5 for benchmarking. Multi-modal video+audio generation model Ovi (Veo-3-like) is released. Retrieval models include ModernVBERT from MIT with efficient image-text retrieval capabilities. "Claude Sonnet 4.5 is basically the same as Opus 4.1 for coding" and "Jules is a programmable team member" highlight key insights.
