Cohere releases Command A Reasoning, its first reasoning model

Background

Command A Reasoning was Cohere's first reasoning model. Reasoning models work through a problem step by step before giving an answer ^[1].

What happened

On 21 August 2025 Cohere released Command A Reasoning, a hybrid reasoning model for complex agentic tasks ^[1]. The weights were published on Hugging Face under a non-commercial licence ^[2].

Key details

The model has 111 billion parameters and a 256k-token context ^[2]. Users can turn thinking on or off and set a thinking budget ^[1]. The model works in English and 22 other languages ^[1].

Cohere said it has the strongest tool use in the Command family ^[1].

Impact

The release added a reasoning model to Cohere's lineup, and Oracle later offered it through its OCI Generative AI service together with Command A Vision. For developers, the switch between thinking and non-thinking modes gave one model two ways of working, depending on how hard a task was.
