SpaceXAI unveils Grok 4.6, claims frontier-level performance at lower cost
A company called SpaceXAI has made a new smart computer program called Grok 4.6.
The company introduced it on Wednesday, August 12.
This program is very good at thinking, writing code, and solving hard problems.
SpaceXAI says it is just as smart as programs made by other big companies like Anthropic and OpenAI.
It is also much cheaper to use than similar programs called Fable 5 and GPT-5.6.
Grok 4.6 can keep working on long, difficult tasks without getting lost.
It can help people research topics, analyze information, and build applications.
It is also built for interactive visual work with pictures.
A test called the Artificial Intelligence Analysis Index shows it is as smart as another program named GPT-5.6 Sol.
SpaceXAI unveiled Grok 4.6 on Wednesday, August 12.
The company claims the model performs on par with frontier models from Anthropic and OpenAI.
Grok 4.6 is reportedly substantially cheaper than Fable 5 and GPT-5.6.
It builds on Grok 4.5 with an emphasis on long-running agents and interactive visual work.
On the Artificial Intelligence Analysis Index, Grok 4.6 ranks on par with GPT-5.6 Sol.
