Comparison · Not in llmwise
ChatGPT vs Llama
llmwise has 4 of OpenAI's GPT models, from GPT-6 Luna (up to 60 messages a day on Pro) to GPT-6 Astra (up to 31 messages a month). It doesn't offer Llama, so you can't try the two side by side here. What follows is how they differ in kind, when each makes sense, and what llmwise has that comes closest.
What each is
GPT
GPT is the family of AI models made by OpenAI, the company behind ChatGPT. It's in llmwise: GPT-6 Astra, GPT-6.1 Sol, GPT-6 Sol, and GPT-6 Luna.
Llama (not in llmwise)
Llama, which llmwise doesn't offer, is Meta's family of open-weight models: Meta publishes the weights, so it isn't tied to one company's service.
The difference that matters
The main difference is in kind. An open-weight model's weights are public, so you can run it on your own hardware, fine-tune it, or pick who hosts it; Llama, which llmwise doesn't offer, is one of those. The GPT models in llmwise are used as a service. In llmwise, a message to GPT goes to its maker, OpenAI, or through OpenRouter when llmwise can't reach the maker directly.
When each makes sense
Choose an open-weight model such as Llama (not in llmwise) when you need to run it yourself: on your own hardware, fine-tuned on your own data, or somewhere your data never leaves.
Choose GPT in a chat when you want answers without running anything: in llmwise you pick a model, ask, and see each message's price before you send it.
Not sure? Ask the same real question of two models and compare the answers: that settles more than any benchmark.

Every limit is published. Paid plans also have a monthly fair-use limit on AI cost: Plus $3.75, Pro $7.50, Max $20, Ultra $42, Studio $85. Using every message on your plan at typical sizes stays under it; very large messages and heavy research use it faster. Every limit, explained.
The closest in llmwise
If a low price is what you were after, these are the lowest-priced models in llmwise: the everyday models, on a paid plan's daily count, and Claude Haiku 4.5-class models (250 messages a month on Pro).

If it's open weights you want: the one model in llmwise that our catalog calls open-weight is GLM 5.3 (“Z.ai's capable open-weight model”). In llmwise you use it in the chat, not on your own hardware.
Try them on your own question
Start a chat on GPT and ask a real question from your work, with any files it needs.
Switch the model picker to GLM 5.3 and ask for its answer to the same question. It sees the whole chat, including GPT's answer.
Compare the two on what matters to you: accuracy, tone, length, how much you'd have to fix. If it's close, ask each a follow-up.
The badge by each model in the picker shows what a message uses before you send it.
More on this in how to compare LLM models.
Where your messages go
In llmwise, a message to GPT, Claude, or Gemini goes to the model's maker, or through OpenRouter when llmwise can't reach the maker directly. GLM, DeepSeek, Mistral, and Grok models are served only through OpenRouter, by endpoints that don't store or train on prompts. The Privacy Policy has the details.
Questions
Does llmwise have Llama?
No. llmwise doesn't offer Llama. The one model in llmwise that our catalog calls open-weight is GLM 5.3 (“Z.ai's capable open-weight model”). llmwise's lowest-priced models are the everyday ones: Claude Haiku 5.5, GPT-6 Luna, DeepSeek V4.1 Flash, and GLM 5.3 Flash.
Which is better, ChatGPT or Llama?
We can't settle that for you: llmwise doesn't offer Llama, and we don't publish benchmark scores. It depends on the job, and on whether you need to run the model yourself; for a chat, try GPT and a lower-priced model on your own question.
Is GPT or Llama cheaper?
We can't compare prices: Llama isn't in our catalog, and an open-weight model's price depends on who hosts it or what your hardware costs. In llmwise, GPT's least expensive model is GPT-6 Luna (60 messages a day on Pro), and the count is shown before you send.
Claude, GPT, Gemini, DeepSeek, Grok, Kimi, GLM, and Mistral, in one chat.
