**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.
