Model overview
Grok 4.3 is a reasoning model from SpaceXAI. It accepts text and image inputs with text output, and is suited for agentic workflows, instruction-following tasks, and applications requiring high factual...
The summary below is compiled from sources by an AI model, not our own testing. Verify selection decisions against original sources and your workload.
Key features
- Supports multimodal inputs including text, images, and files
- Designed for reasoning-intensive tasks and agentic workflows
- Capable of generating structured outputs and integrating with tools
Limitations & considerations
Sources are insufficient to establish specific limitations. Verify task performance, latency, data policies, licensing and version lifecycle.
Source prices & cost analysis
Prices vary by channel, region and configuration. Channel quotes are listed independently and are not treated as a single official provider price.

Does Grok 4.3 support image understanding?
Yes, Grok 4.3 accepts image inputs as stated in its supported input modalities.
What types of input files does Grok 4.3 accept?
The documentation confirms file input is supported, but specific file formats are not specified.
Is Grok 4.3 optimized for instruction-following tasks?
Yes, the description explicitly states it is suited for instruction-following tasks.
Do open weights permit free commercial use?
Not necessarily. Check the version license, commercial conditions and usage policies. Self-hosting incurs compute and maintenance costs.
Are these real-time billing prices?
These are timestamped source snapshots, not live billing prices. Check the channel for current versions, regions, discounts and billing methods.
