ChatGPT Free costs $0 and Go costs $8 per month in the current US plan guide. The useful decision is whether the Go offer shown in your account solves a recurring limit. Work/Codex documentation alone does not establish the full consumer Chat feature difference, so check that exact offer before upgrading. Current plan guide

Identify the interruption
Start with the Free account and record what actually stops a task. Go is an $8 monthly purchase; a paid label alone does not establish that it solves your particular limitation. In the current Work/Codex guide, both Free and Go list GPT-6 Luna at Standard speed in the desktop app, subject to rollout. If that is your entire workflow, this guide does not establish a new model or surface that requires Go. Current plan documentation
Record limits by feature and surface rather than treating every action as one pool. A completed ordinary conversation does not establish that a file-analysis task or a coding run has the same allowance. Name the recurring task and the specific interruption that an upgrade must remove.
What the price buys
The US list prices are $0 monthly for Free and $8 for Go. Local currency, tax and purchase channels can change the checkout. Compare the exact consumer tools your account offers before paying; Work/Codex entitlements are not a complete inventory of ordinary Chat features. API usage is separately billed and should not be inferred from either plan. Prices and accounting
Go does not unlock every higher-tier model or work capability. If the feature you need is specifically associated with Plus or Pro, spending less on Go may still fail to solve the problem. Conversely, a more expensive tier is unnecessary if Go removes the only recurring interruption.
A useful student or household trial
Take an ordinary task involving information you may safely upload: summarize a permitted reading, compare a small household budget CSV or organize notes into a checklist. Specify an output you can verify. Record which steps the free plan completes and where access stops.
After an upgrade, repeat the same task. Check that numbers, source meaning and requested constraints remain correct. More available uploads are valuable if they reduce manual work; they do not guarantee accurate analysis. We have not tested this workflow or measured the two plans' relative output quality.
Avoid outdated feature assumptions
A screenshot from an old plan chart is not a reliable entitlement list. Check the actual account, feature and surface you intend to use. For tasks that require broader Work or developer access, the documented plan ladder also includes Plus; buying Go first is not automatically a necessary step. Current plan ladder
Keep the upgrade reversible
Write down one reason to upgrade and one condition for canceling. For example, Go is worthwhile if it removes repeated upload interruptions; it is not worthwhile if you use no additional tools after a month. The free plan is a valid long-term choice when it completes the work. Buy capacity for a demonstrated use, not a paid badge or an expectation that every answer will improve.
