OpenAI rolled out GPT-5.6 featuring a new model stratification with tiers Luna / Terra / Sol and effort levels including Max and Ultra, introducing complex configuration options. The launch faced UX challenges with the ChatGPT Work / Codex split, prompting rapid corrective actions including usage-limit resets and UI improvements. Early benchmarks show GPT-5.6 excels in agentic coding, presentation, and science tasks, tying with Claude Fable 5 in Code Arena Frontend at about half the cost, and achieving a significant 500-point Elo gain in presentations. However, users noted instruction-following issues and concerns about jailbreakability. The major advancement is in orchestration and computer use, with Sol Ultra demonstrating strong planner and verifier capabilities, enabling high-throughput automation workflows. A notable operational challenge is the hidden cost explosion from spawned subagents inheriting premium settings, causing faster quota depletion.
