ChatGPT is OpenAI's assistant product. This card covers the GPT-5.6 generation in ChatGPT as of the Aug 2026 review (including the August ChatGPT update that replaced an earlier 5.5 default for many plans).
Catalog note
OpenAI changes default model names often. Treat "GPT-5.6" as the generation we reviewed, not a promise that the label will stay on the button. Confirm the live picker. The older GPT-4o card in this catalog stays for history.
Why operators care
ChatGPT is still the door most teams already have. The useful question is which account type you are on (personal vs a work plan) and whether training / retention settings match the data you paste.
What to verify in-product
- Current default vs a named GPT-5.6 / reasoning model
- Voice, vision, and file tools enabled on your plan
- Workspace vs personal account — paste hygiene first
Honest limits
- Multimodal and tool features vary by plan and region.
- Custom GPTs are not a source of truth unless you put the source in them and keep it dated.
- A fluent answer is not a citation.
Best use cases
- Operator packets (role, constraints, examples, eval) on repeating jobs
- File extract and rewrite when the file is the source
- Voice or vision only when you have checked what leaves the device
