About OpenAI Vision Models

OpenAI ships vision models on two tiers, and our catalog tracks 13 of them. 1 is open-weight: the weights are downloadable, so you can self-host under their own licenses. The other 12 are proprietary, reached through an API and billed by the provider. The open-weight side runs on MIT terms. The newest additions are GPT-5.6 Luna (Jul 2026) and GPT-5.6 Sol (Jul 2026). The lineup reaches back to CLIP, released Feb 2021.

Between them, the OpenAI models we list cover 12 distinct vision tasks. The widest coverage is classification (13 models), image tagging (13), and captioning (12). For classification, start with GPT-5.6 Luna, GPT-5.6 Sol, or GPT-5.6 Terra.

On the API tier, OpenAI's most recent entry is GPT-5.6 Luna (Jul 2026), billed per token by the provider rather than run on your own hardware. Which tier to start on is a constraints question, not a quality one: reach for the open-weight side when you need offline inference, predictable per-image cost, or a checkpoint you can fine-tune on your own data, and for the API side when you want broad general reasoning without managing GPUs. 12 of the 13 OpenAI vision models run live in the Roboflow Playground, so you can run the same image through several of them and compare the answers before committing to one.

Frequently Asked Questions About OpenAI Vision Models

Which OpenAI models can do classification?

13 of the 13 OpenAI vision models we track handle classification: GPT-5.6 Luna, GPT-5.6 Sol, GPT-5.6 Terra, GPT-5.5, GPT-5.4 Mini, and GPT-5.4 Nano, and 7 more. Each model page lists its full task coverage, license, and specs.

Which OpenAI models can do image tagging?

13 of the 13 OpenAI vision models we track handle image tagging: GPT-5.6 Luna, GPT-5.6 Sol, GPT-5.6 Terra, GPT-5.5, GPT-5.4 Mini, and GPT-5.4 Nano, and 7 more. Each model page lists its full task coverage, license, and specs.

Are OpenAI vision models open source?

Partly. 1 of the 13 OpenAI vision models we track is open-weight (CLIP), downloadable and self-hostable under its license (MIT). The other 12 are proprietary and reached through OpenAI's API.

What is the best OpenAI model for classification?

We do not publish an OpenAI-only ranking, so pick on constraints rather than a label. 13 OpenAI models handle classification; the most recent is GPT-5.6 Luna (Jul 2026), and CLIP is the newest open-weight option if you need to self-host. For fixed categories in production, a model fine-tuned on your own data typically beats any general-purpose model.

How many OpenAI vision models are on Roboflow Playground?

We track 13 live OpenAI vision models, 1 open-weight and 12 available through an API. The most recent addition is GPT-5.6 Luna, released Jul 2026.

Can I try OpenAI vision models for free?

Yes. 12 of the 13 OpenAI models run live in the Roboflow Playground. Upload your own image, run several models on it at once, and compare the outputs side by side. No setup and no account required.

This page lists all 13 OpenAI vision models in the Roboflow Playground catalog: 1 open-weight model you can self-host and 12 proprietary models accessed through an API. They cover classification, image tagging, and captioning, among other tasks. 12 of them run live in the Roboflow Playground on your own images. Compare licenses, parameters, prices, and release dates side by side, or open any model page for full details.
