This is not a comparison between a good product and a bad one. ChatGPT is the most complete AI product that exists and saying otherwise would be silly. It is a comparison between two different answers to one question: when you ask something that matters, how many models should get a say.
Full disclosure
We build MODUS, which we have placed first. Judge the ranking accordingly. Every ChatGPT figure below comes from openai.com on 1 October 2026 and every MODUS figure from our own pricing page, so all of it is checkable.
Price
| MODUS | ChatGPT | |
|---|---|---|
| Free | $0, no card, open models on a rolling window | $0, GPT-5.6 Luna text chat |
| Entry paid | $24/mo | Go $8/mo, Plus $20/mo |
| Top plan | $59/mo | Pro from $100/mo |
| Multi-model | Compare mode, included on PILOT | Not available at any tier |
ChatGPT is cheaper at the entry tier and MODUS is cheaper at the top, by a wide margin. The line that actually decides this, though, is the last one.
How many labs answer
| Lab | In MODUS | In ChatGPT |
|---|---|---|
| OpenAI | GPT-5.6 Terra, GPT-5.6 Sol | GPT-6, and GPT-6 Astra on Pro |
| Anthropic | Claude Sonnet 5, Claude Opus, Claude Fable 5 | Not available |
| Gemini 3.1 Pro, Gemini 3.5 Flash, Flash Lite | Not available | |
| Meta | Llama 4 Maverick, Llama 3.3 | Not available |
| DeepSeek | DeepSeek V3.1 | Not available |
Eleven models across five labs against a deep catalog from one. That is the whole trade, stated plainly: ChatGPT goes deeper inside OpenAI than MODUS does, and MODUS is the only one of the two that leaves OpenAI at all.
Knowing which model answered
MODUS names the exact model on every answer. If a provider fails and the request falls back to another model, the interface says so rather than presenting the substitute as the one you picked. No silent downgrades.
This matters precisely when it is hardest to notice. When an answer is wrong, the first useful question is which model produced it and at what effort. If the product will not tell you, you cannot ask.
The one thing a single lab cannot do
Every model in this category can produce something confident and incorrect, and none of them will flag it. ChatGPT cannot tell you that Claude would have disagreed, because it has no idea what Claude would have said. This is not a defect in ChatGPT. It is what a single-lab product is.
Compare mode is the alternative. Send one prompt to many frontier models at once and read the answers side by side with a verdict on which served you best. Where they agree, move fast. Where they split, that is the part worth checking, and you find it in seconds instead of after you have acted on it.
One answer is an assertion. Two answers that differ is a flag.
Who should pick which
Pick ChatGPT if you want one excellent product and you are content inside one lab. Codex, custom GPTs, scheduled tasks and Sora are real work that MODUS does not do, and if those are what your day runs on then Plus at $20 is the right answer and this page should not talk you out of it.
Pick MODUS if you are already paying for more than one AI subscription, if you want models from several labs in one place, if you want to know which model answered, or if you want several of them on the same question without opening three tabs and paying three times.
The two are not really competing for the same slot. One is the best single-lab product on the market. The other is for people who have decided that one lab is not enough.
