For individual users in the U.S., ChatGPT is listed at $0/month for Free, $8/month for Go, $20/month for Plus, and $100, $200, or $500/month for Pro. Go, Plus, and Pro are monthly plans. Prices and features can change, so check your account’s current price before subscribing. (chatgpt.com)
| Plan | U.S. monthly price | A specific reason to consider it |
|---|---|---|
| Free | $0 | Try ChatGPT; some features and limits are restricted. |
| Go | $8 | More messages with tools, uploads, image creation, voice chats, and longer memory than Free. |
| Plus | $20 | Adds advanced reasoning models with GPT-6, expanded deep research, and expanded Codex usage. GPT-6 access depends on rollout and account eligibility. |
| Pro 100 | $100 | Pro reasoning and no five-hour Work and Codex usage limit; an included allowance still applies. |
| Pro 200 | $200 | A higher-usage Pro tier than Pro 100. |
| Pro 500 | $500 | The highest included usage of the Pro tiers; includes Ultrafast. |
OpenAI describes Plus as including advanced reasoning models with GPT-6, while its model guidance says GPT-6 availability is subject to rollout and account eligibility. That’s a concrete reason to consider the $12/month step from Go to Plus if you need those advanced reasoning options or Plus’s expanded deep-research access; confirm what appears in your account.

OpenAI lists Pro 100, Pro 200, and Pro 500 as monthly plans. Its current Pro guidance distinguishes the tiers by included usage and identifies Pro 500 as the tier with Ultrafast. (chatgpt.com)
Which ChatGPT plan should you pay for?
- Choose Free if its available features meet your needs and you are not regularly hitting a limit.
- Consider Go at $8/month if you want higher limits for everyday features such as uploads and image creation, without paying Plus pricing.
- Consider Plus at $20/month if you need expanded deep research, advanced reasoning models with GPT-6, or expanded Codex usage. GPT-6 availability can depend on your account and rollout timing. (
chatgpt.com) - Consider Pro 100 at $100/month if you need Pro reasoning or regularly run into the five-hour Work and Codex limit on Plus. Pro removes that five-hour limit, but it still has an included usage allowance. (
chatgpt.com) - Consider Pro 200 or Pro 500 if you need the higher included usage; choose Pro 500 if you specifically need Ultrafast. Do not assume the higher price guarantees a fixed number of extra completed tasks. (

The jump from Plus to Pro 100 is $80 more per month. Go to Plus is $12 more per month. Compare those price steps with the feature or limit you actually need—not just labels such as “expanded” or “higher usage.”
Does a ChatGPT subscription include production API use?
No. ChatGPT subscriptions and API usage have separate billing systems. Eligible paid Pro subscribers may claim API credits, but the benefit must be activated; having an eligible subscription does not mean a credit grant has already been issued. OpenAI lists Pro 100, Pro 200, and Pro 500 grants of $100, $200, and $500 per monthly billing period, respectively. To claim, the paid subscription must have been active for at least seven days; the subscription or workspace owner must also own the API organization receiving the grant and use the same email address for the linked accounts. The first grant may be prorated. (help.openai.com)
The credits fund one linked API organization and are subject to API terms, policies, and organization/model rate limits. They do not increase ChatGPT or Codex usage. Unused credits expire at the end of the billing cycle and do not roll over. The benefit is described for building apps and agents with the API, but the cited guidance does not enumerate model-specific exclusions. For the gpt-6.1-sol example below, count a credit offset only after activation and confirmation that the grant is available to the linked organization for that usage. (help.openai.com)
Estimate API cost from token volume
A basic estimate is:
API cost = (input tokens ÷ 1,000,000 × input rate) + (output tokens ÷ 1,000,000 × output rate)
At the standard rates listed for gpt-6.1-sol—$2 per million input tokens and $10 per million output tokens—a hypothetical month with 1 million uncached input tokens and 100,000 output tokens comes to $3 gross: $2 + $1. This assumes each request has no more than 272,000 input tokens; a request above that threshold has higher input, cache, and output rates applied to the full request. Check the live API pricing and model details before budgeting. ()
This is a gross API estimate, not a personalized budget or a recommendation that the model fits a particular production task. A lower token price alone does not establish that a model meets your quality, latency, or reliability needs. Measure expected input and output tokens, check applicable request conditions and organization/model limits, and treat subscription-linked API credits as a separate offset only after confirming activation and applicability.
Bottom line: Compare Go and Plus based on the features you need; consider Pro when a specific model or usage limit justifies the added cost. If you are building a product, budget API usage separately using current model rates and realistic input and output token volumes.
