Add a Mid-Tier Plan Between Plus and Pro

Please consider offering a mid-tier subscription focused on increased Advanced Voice usage and higher message limits without requiring the full Pro feature set. The jump from Plus at $20/month to Pro at $100-$200/month is extremely significant and may be prohibitive for many personal users. Some users do not need advanced Codex features, maximum deep research limits, or other professional-level capabilities, but would gladly pay for expanded voice usage, higher limits, and priority access. A mid-tier plan would provide a more affordable upgrade path for users who have outgrown Plus but cannot justify the cost of Pro.
