Thinking levels: Always thinks · high · medium · low
Grok 4.5 is a SpaceXAI model with frontier-level results in coding, knowledge work and science, technology, engineering and maths. It reads text, images and PDFs over a 500K-token context and always reasons, with low, medium or high effort. Newer Grok versions (4.6 and 4.7) have followed it.
It accepts text, image and file (PDF) input and returns text, and supports tool calling, structured JSON output and streaming. It always reasons before answering, and you choose how hard it thinks with the reasoning effort setting. Grok 4.5 is commonly used for coding, STEM problem solving, knowledge work and document and image analysis. Hormouz serves it behind an OpenAI-compatible API: point your base URL at Hormouz, drop in a Hormouz key, and existing OpenAI SDK code runs without changes.
Pricing is usage-based: $2 per million input tokens and $6 per million output tokens. There is no fixed monthly fee, and you pay only for the tokens you use. Hormouz provides stable access to the model from inside Iran, with no foreign credit card or circumvention tooling required.
Grok 4.5 is a model from SpaceXAI with frontier performance on coding, knowledge work, and STEM.
