Vision & multimodal
These OpenLux models accept image input alongside text — screenshots, photos, charts, diagrams and UI captures — and are called with the standard OpenAI image_url content parts. Seven models, three price tiers, one endpoint.

Vision unlocks the workflows that pure text models cannot touch: reading dashboards, describing product photos, transcribing whiteboards, QA-testing interfaces and turning screenshots into bug reports. On OpenLux the image travels inside the same chat request, so a vision feature is usually a few lines added to existing chat code.
The spread between the cheapest and most capable vision model is roughly 40x per token, which is why the tier you choose matters. Flash-tier Gemini handles high-volume reading and extraction; GPT-6 Astra, Claude and Gemini Pro tiers take on chart reasoning, UI understanding and tasks where being wrong is expensive.
The picks
7 models from the live catalogue, with the rate each one is metered at.

Vision & multimodal questions
Which models on OpenLux accept image input?
GPT-6 Astra, GPT-5.6 Sol, Gemini 3.8 Flash, Gemini 3 Flash preview, Gemini 3.1 Pro preview, Claude Sonnet 4.5 and Claude Fable 5.1.
How do I send an image in a request?
Use the standard OpenAI content-parts shape: a message content array with an image_url entry, which accepts either a public URL or a base64 data URI. The same payload works on every vision model — only the model name changes.
Which vision model is the cheapest?
Gemini 3 Flash preview at $0.0368 per 1M tokens, about 92% below official list pricing. For reading-heavy pipelines it is usually the right default, with a stronger tier reserved for low-confidence cases.
Do I need separate keys for OpenAI, Anthropic and Google vision models?
No. One OpenLux key covers all of them and every request appears on one invoice, so comparing vision models on your own data costs a model-name change rather than a new provider integration.
