Nvidia open-sources a 30B mixture-of-experts model that activates only 3B parameters yet matches DeepSeek's 671B model on olympiad-level math and coding benchmarks.
An anonymous trillion-parameter AI model that topped OpenRouter usage charts and triggered widespread speculation about a stealth DeepSeek V4 launch turned out to be Xiaomi's MiMo-V2-Pro, signaling the smartphone and EV maker's escalating ambitions in the AI model race.
OpenAI releases its most capable model yet with autonomous computer operation and enterprise integrations, but the launch is overshadowed by Pentagon deal fallout and a reported 1.5 million user exodus.
DeepSeek's first major AI release in over a year arrives amid Anthropic allegations that the Chinese lab used 24,000 fake accounts and 16 million queries to extract Claude's capabilities.
OpenAI's smaller, speed-optimized Codex-Spark model runs on Cerebras' Wafer Scale Engine 3, marking the AI giant's first move off Nvidia silicon for production inference.
Both models launched on the same day but target different developer needs — Codex prioritizes speed and agentic reliability, while Opus leads on reasoning depth and multi-agent coordination.
OpenAI releases GPT-5.3-Codex, its fastest agentic coding model yet, but delays API access after classifying it as 'High' cybersecurity capability under its Preparedness Framework.
Anthropic releases its most capable model yet, featuring a 1M-token context window, parallel agent coordination, and security research that uncovered over 500 previously unknown vulnerabilities in open-source software.
