Codex Pro 500 - Official Personal Upgrade

1. Important Notes

Codex Pro 500 - Official Personal Upgrade at Empire X activates OpenAI's highest-tier individual subscription (officially priced at $500 USD/month) directly on your personal account, unlocking OpenAI Codex coding agent usage limits 25 times higher than the Plus plan alongside exclusive Ultrafast speed mode for GPT-6 Astra and GPT-6.1 Sol. All of your code repositories, project configurations, and conversation histories remain completely intact and 100% private.

• Account Type: Official personal upgrade applied directly to the customer's individual OpenAI / ChatGPT (Email/Gmail) account. This is never a shared account, ensuring stable connections across GitHub, IDEs, eligible third-party apps (such as v0), and the Codex CLI without session conflicts.
• Target Audience: Senior/Staff software engineers, system architects, and AI developers running intensive autonomous coding agents across the Codex CLI, IDEs, and Cloud who require ~300 tokens/second generation speeds (Ultrafast) and usage headroom far exceeding the Pro 200 ($200/month) tier.
• Privacy: All connected GitHub/GitLab repositories, configuration files, Codex session histories, and ChatGPT Work tasks remain completely isolated on your personal account—no one else can view or access your data.

Important Warnings:

• Do not manually cancel the subscription, modify payment methods, or tamper with the Billing settings in your account after the upgrade has been completed.
• The account being upgraded must not have an active paid subscription currently billed through the Apple App Store or Google Play Store (if applicable, please cancel the renewal and wait for the billing cycle to expire before upgrading).
• Strictly do not share your account login credentials with multiple users or use unauthorized automated data-extraction tools, as OpenAI's Terms of Use prohibit sharing Pro credentials and will restrict access for misuse.
• Ultrafast speed mode on GPT-6 Astra and GPT-6.1 Sol consumes your plan's included allowance at 8 times the Standard rate (and can consume up to 17% of your weekly quota on a single massive multi-file job); please toggle Ultrafast strategically for urgent tasks to optimize your 25x allowance.

2. Product Details

Codex Pro 500 is the flagship individual developer and AI subscription tier announced by OpenAI at DevDay (September 29, 2026) with an official international retail price of $500 USD/month ($6,000 USD/year), bundled directly inside the ChatGPT Pro 500 plan. The subscription delivers a shared usage allowance across OpenAI Codex and ChatGPT Work that is 25 times higher than the Plus ($20/month) plan, permanently removes the 5-hour rolling window limit, and stands as the only self-serve plan that includes Ultrafast speed mode. By choosing Codex Pro 500 - Official Personal Upgrade at Empire X, you secure OpenAI's most powerful Agentic Coding tier directly on your personal account at significant cost savings.

How does the exclusive Ultrafast speed mode on the Pro 500 plan work?

Across OpenAI's three Pro tiers (Pro 100, Pro 200, and Pro 500), only the Pro 500 plan includes Ultrafast mode (even purchasing additional credits on Pro 100 or Pro 200 does not unlock it):

• GPT-6 Astra Ultrafast & GPT-6.1 Sol Ultrafast: Accelerates Codex execution up to 8 times faster than Standard mode and 4 times faster than Fast mode, achieving generation speeds of up to 300 tokens per second.
• Priority Allowance Drawdown: When you select Ultrafast in the model picker, it draws from your plan's included 25x usage allowance first at 8× the Standard rate for the selected model (and draws from purchased credit balances at 6× the Standard credit rate once the included allowance is exhausted).
• Tactical Speed Optimization: You can rely on Standard or Fast mode as your practical daily driver to conserve quota, and engage Ultrafast as a high-speed emergency lever when refactoring complex codebases or debugging critical blockers minutes before a deadline.

How powerful are the 25x Plus allowance and coding ecosystem on Pro 500?

This upgrade provides OpenAI's largest individual compute budget for software engineers:

• 25x Plus Allowance & No 5-Hour Rolling Cap: Delivers a weekly usage allowance 25 times larger than the Plus plan (5x larger than Pro 100 and 2.5x larger than the updated 10x allowance taking effect October 30, 2026, on Pro 200). Crucially, OpenAI enforces no five-hour limit on Pro plans, letting you spend your weekly allowance whenever your project sprint demands it.
• Full Coding Model Lineup & Agents API Computer Use: Unlocks comprehensive access to GPT-6 Astra (GPT-6 Pro), GPT-6.1 Sol, GPT-6 Sol, and GPT-6 Luna, while exclusively including the Agents API with computer use inside ChatGPT Work and Codex.
• Multi-Surface Sync & Third-Party App Support: Work seamlessly across Codex Web, CLI (Terminal), IDE Extensions (VS Code, Cursor, JetBrains), Desktop App, and iOS, complete with Automatic Code Review, Slack integrations, and eligible usage inside third-party apps such as Vercel's v0.

How does the Pro 500 plan differ from the Free tier and Plus ($20) / Pro 200 ($200)?

The Free ($0) and Go ($8/month) tiers only support lightweight coding tasks using GPT-6 Luna at Standard speed in the desktop app and lack cloud integrations. Meanwhile, the Plus plan ($20/month) is restricted by 5-hour rolling windows (averaging 5–45 GPT-6 Astra or 15–160 GPT-6.1 Sol local messages per 5 hours), and the Pro 200 plan ($200/month) drops from 20x down to 10x Plus after October 29–30, 2026, without any Ultrafast access. Upgrading to Codex Pro 500 - Official Personal Upgrade secures the highest 25x Plus ceiling alongside exclusive Astra & Sol Ultrafast inference speeds.

Key Features

• Exclusive GPT-6 Astra & GPT-6.1 Sol Ultrafast Mode: Generate code and complex architectural reasoning at up to 300 tokens/second (up to 8x faster than Standard mode) for near-instantaneous turnarounds.
• Highest 25x Plus Usage Allowance: Access a unified usage pool shared between Codex and ChatGPT Work that is 25 times larger than Plus and 2.5 times larger than the standard Pro 200 tier.
• Zero 5-Hour Rolling Window Limits: Spend your entire weekly compute budget freely across intensive multi-day engineering sprints without mid-session throttling.
• Agents API (Computer Use) & Multi-Surface Integration: Automate computer-use workflows in Work and Codex, synced across CLI, IDEs, Web, Desktop, Slack, and partner platforms like v0.
• Complete ChatGPT Pro $500 Ecosystem Bundled: Simultaneously enjoy every flagship feature of ChatGPT Pro (including Deep Research, ChatGPT Space, Word/Excel/PowerPoint integrations, AI image creation, and Sora) under the same login.

5. FAQ

1. What is Codex Pro 500? It is OpenAI's highest-tier individual subscription plan (launched on September 29, 2026, at an official retail price of $500 USD/month), bundled directly inside the ChatGPT Pro 500 subscription. The plan provides 25 times the Plus allowance across Codex and ChatGPT Work alongside exclusive Ultrafast speed mode on GPT-6 Astra and GPT-6.1 Sol.

2. How does the Codex Pro 500 plan differ from Codex Pro 200 and Pro 100? The primary difference is that only Pro 500 includes Ultrafast speed mode and the Agents API with computer use in Work and Codex, backed by a 25x Plus usage allowance. By contrast, Pro 100 offers a 5x allowance and Pro 200 provides a 10x Plus allowance (effective October 30, 2026), and neither tier includes Ultrafast.

3. How fast is Ultrafast mode on Codex Pro 500 and how does it consume my allowance? Ultrafast runs GPT-6 Astra and GPT-6.1 Sol up to roughly 8 times faster than Standard mode and 4 times faster than Fast mode, reaching generation speeds of up to 300 tokens per second. Enabling Ultrafast consumes your plan's included allowance first at 8× the Standard rate for the selected model, making it ideal to save Fast/Standard mode for routine coding and toggle Ultrafast on for urgent tasks.

4. Do I also get full access to ChatGPT Pro 500 when purchasing this upgrade? Yes, because OpenAI unifies Codex and ChatGPT under the exact same personal subscription. When upgraded at Empire X, your 25x allowance is shared across Codex (Web, CLI, IDE, iOS), ChatGPT Work, and eligible third-party partner integrations such as Vercel's v0.

5. Will I lose my existing chat history or project configurations when upgrading at Empire X? Not at all, because the subscription is activated directly on your personal OpenAI account. All of your existing conversation history, connected GitHub repositories, personalized Memory, and custom settings remain 100% intact.

6. Are my source code and project data kept completely private on this account? Yes, your data is 100% private because this is your own personal account rather than a shared account. No one else can access or view your code repositories, internal documents, or prompt histories executed in Codex.

7. Is the Codex Pro 500 plan throttled by 5-hour rolling limits during continuous agent runs? No, as of OpenAI's September 29, 2026 update, Pro plans have no five-hour rolling limit. You can spend your entire 25x weekly allowance whenever your workload requires it rather than rationing usage across rigid 5-hour windows like on the Plus tier.

8. How can I check my remaining Codex allowance and reset times? Inside the Codex CLI, simply run the /status command to view remaining limits or /usage to inspect daily, weekly, or cumulative activity. You can also monitor your usage and reset times under Settings → Usage in ChatGPT or Usage & Billing inside the Codex dashboard.

9. How does Empire X support me if my account loses its Pro 500 status during the subscription period? If you encounter any issues with your subscription benefits during your active term, simply contact Empire X customer support immediately with your order ID. Our technical team will quickly inspect and resolve the issue, replace it with an equivalent new upgrade, or issue a prorated refund for the unused time.

10. Where can I buy a genuine, affordable Codex Pro 500 upgrade reputably in Vietnam? Empire X is a leading trusted platform in Vietnam providing genuine, cost-effective Codex Pro 500 personal upgrades activated directly on your account within 15-30 minutes.
