GPT
OpenAI’s models, versatile all-rounders that hold up across a wide range of tasks.
GPT is the safe default for a huge range of work. It is broadly capable, reasons well, and handles structured output cleanly, which makes it a reliable first opinion in almost any weave.
The lineup
| Model | Best for | Plan |
|---|---|---|
| GPT-5.4 | Flagship reasoning for the hardest tasks. | Paid |
| GPT-5.4 Mini | Most of the flagship’s quality, faster and cheaper. | Paid |
| GPT-5 Mini | A capable compact model for routine work. | Paid |
| GPT-5 Nano | Quick, low-cost answers. Included on the free plan. | Free |
What it is good for
- General-purpose tasks where you want a dependable answer
- Structured output and instruction-following
- Broad knowledge across many domains
- A strong baseline to compare other models against
In a weave
GPT is a common anchor in a weave: a solid answer to measure the others against. When models agree with GPT, you can trust the result more; when they split, you have found the part worth a closer look.
GPT-5 Nano is one of the free models, so free-plan weaves often include it in the mix.
GPT-5 Nano is included free. The larger GPT models are on the paid plans.
Common questions
Is any GPT model free on LLMWeave?
Yes, GPT-5 Nano is part of the free model set, so you can use it without a paid plan.
GPT-5.4 vs the Mini models?
Use GPT-5.4 for the hardest reasoning. The Mini variants give you most of the quality at lower cost and latency, which is plenty for routine work.
