AI Model Review

Can an open-source Chinese model compete with the closed flagships from OpenAI and Anthropic? Based on our independent testing – yes. On January 27, 2026, Beijing-based Moonshot AI released Kimi K2.5, and it immediately joined the elite group of the world’s best models – competing directly with GPT-5.4 and Claude Sonnet 4.5. And it’s completely free for basic use.

DeepSeek is a Chinese AI startup that has become one of the industry’s leading players in just two years. In April 2026 DeepSeek released V4 – a generation of models that competes with GPT-5.4 and Claude Opus 4.6 on quality while costing 10–50 times less.

GigaChat is a generative AI model from Sber – Russia’s largest bank and technology conglomerate (comparable to a combination of Chase, Google, and Amazon in the Russian market). GigaChat is built specifically for Russian-language audiences and trained on Russian data, with deep understanding of cultural context, slang, and the nuances of the Russian language. It works without a VPN from Russia and CIS countries.

YandexGPT is a family of generative language models from Yandex, available through Alice, Yandex Browser, the Yandex Cloud API, and other ecosystem services. By February 2026, Yandex introduced the new Alice AI model family, which together with YandexGPT forms a powerful platform for working with the Russian language.

Grok by Elon Musk’s xAI is an AI system that stands out from competitors (ChatGPT, Claude) with minimal content filters and direct real-time access to X (Twitter) data. By May 2026, Grok has evolved beyond a chatbot into a full agent ecosystem with native video processing, deeply integrated into Tesla vehicles. The latest model – Grok 4.3 – launched April 30, 2026, bringing a 1M-token context window, 58% price cuts, and native video input support.

Gemini is Google’s generative AI ecosystem, which by February 2026 has become a key tool for companies deeply integrated with Google services. Its main advantage is seamless integration with Google Workspace (Docs, Sheets, Gmail, Drive) and instant access to real-time data through Google Search.

In 2026, Anthropic ships updates every two weeks – and each one shifts the boundaries of what an AI assistant can do. Opus 4.6 launched on February 5, Sonnet 4.6 on February 17, and on April 16 – the new flagship Claude Opus 4.7 with improved coding and high-precision image recognition. A context window of 1 million tokens is now available to all users at no extra cost.
