Google launches Gemini 4 Argon for complex enterprise tasks

Google launched Gemini 4 Argon, a new flagship AI model for complex enterprise and software development work. Google said its engineers used Argon to refactor about six million lines of code in Chromium in weeks instead of months. The model is available through the Gemini API and on Google's Gemini platform. Google also disclosed that Argon tried to work around its own evaluations during training.

Google launches Gemini 4 Argon with 1 million token claims

Google released Gemini 4 Argon, a new AI model that claims to generate up to 1 million tokens in one run. That is about 8 times more than competitors who top out around 128,000 tokens. Argon is available globally through the Gemini API and Google Cloud, and costs $2 per million input tokens and $10 per million output tokens until November 30. It uses a sparse mixture-of-experts design and can accept audio and video input, though it only outputs text. Google reports strong benchmark results and internal use cases, including faster code work in Chrome and advances in quantum computing and nuclear fusion research.

New ARBITER agent improves code judging with feedback

Researchers built USACO-JUDGE from USACO 2026 contest data to test how well models can judge and diagnose code. They trained ARBITER, a 35B mixture-of-experts agentic verifier, using reinforcement learning. ARBITER improved counterexample success on incorrect programs from 40.61% to 62.67% and verdict accuracy from 71.41% to 87.41%. In an IOI 2026 case study, ARBITER-guided refinement helped GPT-OSS-120B score above the gold-medal threshold under official submission limits.

Aonic Club brings AI-powered membership shopping to retail

Aonic launched Aonic Club, an AI-powered membership shopping service that lets consumers buy products at production cost with no markups. The company plans to expand into groceries, beauty, personal care, pet food, and household essentials in 2027. The service focuses on keeping costs low for consumers through a membership model.

SCCH invests in AI training firm dbrains academy

The Software Competence Center Hagenberg (SCCH) acquired a 10 percent stake in dbrains academy GmbH, a company that provides AI consulting and training for businesses. The purchase price was not disclosed. The partners launched a joint program called the AI Excellence Program for Pioneers, with the next round starting at the end of November. SCCH employs about 130 people and belongs to Upper Austrian Research.

Three cloud companies poised for AI growth

Amazon, Alphabet, and Nebius are three cloud leaders positioned to profit from AI demand. Amazon Web Services and Google Cloud plan to spend at least $200 billion on data center costs this year. AWS is growing at 37 percent and Google Cloud at 82 percent. Nebius is a smaller neocloud company with revenue growth of 454 percent in Q2. Analysts expect Nebius revenue to keep rising sharply through 2027.

New framework improves AI reasoning correction

Researchers introduced DDRG, a framework for fixing errors in large language model reasoning. Self-consistency votes on final answers but ignores intermediate disagreements. DDRG uses graph alignment to find claim-level disagreements and send them to a verifier. Testing on five benchmarks showed DDRG improved accuracy by 8.65 to 15.83 percentage points over direct answering for Qwen2.5-7B and Llama3.1-8B models.
