GPT-6 Astra operates with a massive 1-million-token context window, meaning it can hold and reason over extraordinarily long documents, codebases, or conversation histories in a single pass. It accepts both text and image inputs, making it multimodal in what it takes in, though it responds in text only. Details about its specific reasoning style and capability trade-offs are limited beyond these structural characteristics.
