Usage limits in full
- ChatGPT Pro 500
- Any unlimited Pro access is subject to abuse guardrails. Work and Codex allowance doubled automatically; weekly GPT-6 Pro message limits are unchanged. Highest included usage among Pro tiers. GPT-6 Astra and GPT-6.1 Sol Ultrafast consume included allowance at 8x Standard and purchased credits at 6x Standard; these are usage-accounting multipliers, not speed guarantees. Includes $500/month in claimable API credits. Claim after seven paid days by linking an API organization owned under the same email. First grant is prorated; unused credits expire at billing-cycle end without rollover. Credits cover eligible API Platform usage, not Codex via API keys or extra ChatGPT/signed-in Codex limits. API usage uses purchased credits after free credits; requests fail if no balance remains. Free trials and complimentary subscriptions do not qualify. The benefit may change or end; API terms and rate limits apply.
- Google AI Ultra 20x
- Ultra 20x provides 20x AI Pro Gemini usage, with highest access to Gemini 4 Argon, Pro-model access, Flash access, and 25,000 Flow credits monthly. Features and models vary by country. Google Colab includes 2,000 compute units per month.
