Cloud.ru has launched commercial access to its new GigaChat 3.5 Reasoning model, which is now available via the Evolution Foundation Models catalog. Users can integrate the model through an API without the need to manage their own inference infrastructure.
The service is priced at 96 ₽ per 1 million input tokens and 289 ₽ per 1 million output tokens. The platform includes the Guardrails Filter tool for data protection and meets compliance requirements for state information systems and critical infrastructure.
The model features a reasoning mode that decomposes complex tasks into steps and creates execution plans. According to the company, performance in benchmarks improved significantly compared to GigaChat 3.5 Ultra, with IFBench scores rising from 44 to 77 points.
In addition, the model uses a linear attention architecture to handle long contexts efficiently. It reportedly consumes 37% fewer tokens than DeepSeek V4 Flash Preview when performing mathematical tasks, while maintaining comparable output quality.
The Evolution Foundation Models catalog currently hosts over 20 large language models. Cloud.ru positions the new tool as suitable for corporate scenarios in finance, legal services, and software development, where security and compliance are priorities.
