SpaceXAI: Grok 4.5

The x-ai offering, Grok 4.5, is a language model that can process text, images, and files as input. It operates with a context length of up to 500,000 tokens and supports up to 450,000 completion tokens per query. Grok 4.5 may be worth considering for those who require robust reasoning capabilities and integration with tools; it has benchmarked well in this area. However, at $2.00 per million input tokens and $6.00 per million output tokens, Grok 4.5 is likely to be more expensive than some competing models. With a blended benchmark score of 65.0 across one available benchmark, Grok 4.5's performance may justify its cost for certain applications but not others; users should weigh these factors when deciding whether to shortlist this model.
