The Signal
GPT-56/Soul represents a leap in coding autonomy but carries a significantly higher risk of usage exhaustion. While the model is more efficient than its predecessor at completing complex tasks without interruption, users are reporting rapid quota burn—exacerbated by temporary product changes—that demands careful configuration management rather than brute-force usage.
The Case
- OpenAI has temporarily suspended 5-hour rolling usage caps, leaving only weekly limits, which means a single high-reasoning prompt can now theoretically exhaust an entire week's allocation.
- The primary driver of usage intensity is GPT-56’s behavior: it is more capable than GPT-55 but far less likely to pause for confirmation, often performing long, uninterrupted runs that burn through budgets.
- Fast mode is a major latent cost, offering a 1.5x speed increase at the price of 2.5x usage burn; disabling it is the most effective immediate lever for those hitting limits.
- Sub-agents are spawning too eagerly in the current version, so the speaker recommends updating 'agents.md' to explicitly restrict them: "Only use sub agents if the user explicitly requests them."
- Benchmark data suggests diminishing returns on reasoning levels, with costs spiking sharply past the "High" setting without equivalent quality gains, making "High" the recommended default for most users.
- Community-circulated hacks—specifically manual context-window capping and forcing compaction thresholds—are discouraged, as OpenAI reports these defaults are already tuned to be optimal for 56 Soul.
The 1 Minute Signal Take
You should treat your interaction with GPT-56 as a shift from "prompting a chatbot" to "managing an agent." By setting explicit stop points, disabling fast mode, and relying on default context thresholds, you can reclaim control over your usage quota while still utilizing the model’s superior reasoning capabilities.
