Google DeepMind unexpectedly drops new flagship Gemini 4 Carbon, topping AA Intelligence Index and sparking safety and benchmarking debates : Just two weeks after the launch of Gemini 4 Argon, Google DeepMind unexpectedly dropped its new flagship model, Gemini 4 Carbon. In the latest Intelligence Index v5 benchmark released by Artificial Analysis, Carbon took the top spot with a score of 59, edging out Claude Opus 5.5 (58) and GPT-6 Astra, and ranking first in 15 out of 17 core capability benchmarks. Designed specifically for long-horizon autonomous task execution and cybersecurity, the model supports finding subtle bugs across codebases, breaking records across SEC-bench Pro vulnerability mining (88.2%), ExploitGym vulnerability verification (54.8%), and CWE-bench patch generation (71.0%), while achieving a 100% defense rate against indirect prompt injection. Due to its potent offensive and defensive capabilities, Carbon is initially accessible only to trusted cybersecurity defenders, maintaining Argon’s promotional pricing ($2/M input, $10/M output). Meanwhile, because AA v5 introduced undisclosed private test sets that caused open-source model rankings to plunge, heated debates have erupted in the community over potential benchmark-specific overfitting (“benchmaxxing”) and commercial bias.

Microsoft and Alphabet report earnings on the same day: Cloud and AI compute revenues double as multi-hundred-billion capex and ROI tensions escalate : Microsoft and Alphabet reported their quarterly earnings on the same day. For the first time in history, Microsoft broke out Azure’s actual quarterly revenue at $33.2 billion (up 48% YoY), with revenue from its OpenAI commercial partnership reaching $10 billion (nearly 11% of Microsoft’s total revenue) and quarterly capital expenditures hitting $45.2 billion. Alphabet’s Google Cloud, driven by strong compute cluster and TPU system sales, saw quarterly revenue surge 103% YoY to $30.709 billion; however, a 114% spike in quarterly capex to $51.355 billion pushed free cash flow into a negative $9.065 billion deficit. Coupled with AI search monetization lagging behind traditional web search, Alphabet’s stock plunged nearly 10% after hours. The two tech giants’ earnings directly reflect the flywheel effect of token consumption, while highlighting the intensifying tug-of-war between hundreds of billions of dollars in AI capex and real-world ROI delivery.
