GPT-6.1 Sol allowance quietly cut ~20% vs 6 Sol, possibly masked by throttling

@Fei2411's controlled tests found GPT 6.1 Sol's subscription allowance is nearly 20% lower than 6 Sol's, released less than a week earlier.
- Uniform workloads rule out cache-hit-rate differences.
- The community's feeling that "6.1 Sol burns allowance slowly" is real — because the model itself is extremely slow, measured as low as 10+ tok/s.
- Author suspects OpenAI deliberately throttles to create an illusion of generous allowance.
- Conclusion: the $200 Pro plan is even worse value: the multiplier vs GPT Plus was cut, and Plus allowances are shrinking too.
