It shares Sol&rsquo;s 1.05 million token context window and 128,000 token output limit but costs far less to run, at $0.10 per million input tokens and $0.50 per million output tokens, making it OpenAI&rsquo;s pick for high-volume tasks like classification, summarization, and routine chat where the heavier reasoning of GPT-6 Astra or Sol isn&rsquo;t needed.</p>
