最も勢いのあるAI企業5社がそれぞれのフラッグシップモデルを発表し、人工知能開発においてこれまでに見たことのないような熾烈な競争が繰り広げられている。OpenAIは2025年8月初旬にGPT-5を発表し、Anthropicはその数日前にClaude Opus 4.1をリリースした。グーグル・ディープマインドのGemini 2.5 Proは3月下旬に登場し、xAIは7月にGrok 4を発表、そして今回アリババが9月上旬にQwen 3 Maxでゲームに参入した。しかし、これらは実際に大きな進歩なのだろうか、それともささやかな改良をマーケティングに利用しただけなのだろうか？どの企業も、自社のAIを最もインテリジェントで有能なアシスタントだと宣伝し、そのモデルを示す厳選されたベンチマークや洗練されたデモに裏打ちされている。

Alibaba’s AI stack just crossed a symbolic frontier. On September 5 2025, the company’s cloud division unveiled Qwen-3-Max-Preview (Instruct), a 1-trillion-parameter large-language model that immediately takes its place among the most complex systems ever deployed and the most powerful AI models. The rollout began quietly inside Qwen Chat and Alibaba Cloud Model Studio. Soon coming to Fello AI. Only a few months ago, OpenAI’s GPT-4o, Google DeepMind’s Gemini 2.5, and Anthropic’s Claude Opus 4 each claimed slices of the “frontier-model” crown. Meanwhile, China-based challengers have been racing to close the capability gap. By releasing a one-trillion-parameter model, Alibaba is making it clear it wants to compete at the very top, not on the sidelines. […]

Moonshot AI, the Alibaba-backed Chinese startup, has released Kimi K2, an open-source language model with 1 trillion total parameters and 32 billion activated parameters. This release signals China’s most significant attempt yet to close the gap between open-source and proprietary models like OpenAI’s GPT-4 and Anthropic’s Claude Opus. The model is available in two variants: Kimi-K2-Base for researchers and Kimi-K2-Instruct for general-purpose and agentic tasks. Built on a Mixture-of-Experts (MoE) architecture, Kimi K2 supports 128K context length and is designed for complex multi-step reasoning and tool usage. Moonshot has priced access to the model competitively. The input token cost is $0.15 per million, and the output token cost is $2.50 per million, making it significantly cheaper than GPT-4.1 or Claude Opus. According to CNBC, analyst […]
