Use Cases
Software Development
GPT-5.5 and GPT-4o excel at writing, debugging, and refactoring code across any language with deep context understanding.
Document Analysis
Upload PDFs and images directly in chat. GPT-4o vision extracts tables, charts, and text with high accuracy.
Deep Research
200K context in GPT-5.5 lets you paste entire research papers and get synthesized insights in seconds.
Automation & Tools
Function calling enables GPT-4o to invoke APIs, query databases, and execute multi-step workflows autonomously.
When to choose OpenAI over other families
OpenAI models are the industry benchmark for general-purpose reasoning. GPT-5.5 leads in complex multi-step tasks, while GPT-4o Mini offers the best cost-to-performance ratio for high-volume applications.
Compared to Claude, GPT models tend to be more concise and instruction-following. Compared to Gemini, they offer more consistent JSON output and tool-use reliability. o3 Mini is the go-to for STEM and math-heavy workloads.
In Solaria, OpenAI models are available to Premium users, with GPT-4o Mini included in the Premium subscription.

What is the difference between GPT-4o and GPT-5.5?
GPT-5.5 is OpenAI's latest flagship model with 200K context window and superior reasoning for complex multi-step tasks. GPT-4o is a highly capable multimodal model with 128K context, excellent for vision and general-purpose tasks at a lower cost.
Can I use GPT-4o for free in Solaria?
GPT-4o Mini is available to Premium users. GPT-4o and GPT-5.5 require a Premium subscription. You can also bring your own OpenAI API key (BYOK) to access any OpenAI model.
Does GPT-4o support image input?
Yes. GPT-4o and GPT-5.5 both support vision capabilities. You can upload images directly in the Solaria chat and ask questions about them — extract text, analyze charts, describe scenes, and more.
What is o3 Mini best for?
o3 Mini is optimized for STEM tasks, mathematical reasoning, and scientific problem solving. It does not support vision but excels at coding competitions, physics problems, and structured logical reasoning.
Is my data used to train OpenAI models?
No. Solaria never sends your conversations to OpenAI for training. All messages are processed via our API and are not stored or used for model improvement. Your data stays private.
