OPENAI MAPS GPT-5.6 SOL'S FIVE REASONING LEVELS

GPT-5.6 Sol ships with five reasoning levels ranging from "Light" to "xhigh," alongside "Max" and "Ultra" modes that deploy multiple sub-agents in parallel for complex operations. Srivastav recommends users start with lower reasoning levels and scale up only when necessary. This approach balances computational efficiency with output quality. The stratified reasoning system allows developers to match processing intensity to task requirements. Light reasoning handles straightforward queries, while higher tiers engage deeper analysis for complex problems. The parallel sub-agent modes enable sophisticated multi-step reasoning for demanding applications. The guidance addresses a common deployment challenge: maximizing performance while managing resource costs. By providing clear reasoning level recommendations for different task types, OpenAI aims to help teams optimize their use of the model.
