SpaceXAI Unveils Grok 4.5 at $2 per Million Tokens as Musk Calls It Opus-Class

Summary
Grok 4.5 is SpaceXAI’s first model launch since its IPO, with public availability set for Thursday after a beta program that Musk said drew strong customer feedback.
SpaceXAI pitched the model as a lower-cost workhorse for coding, app-building, office tasks, research and writing, claiming twice the token efficiency of leading rivals.
Pricing was set at $2 per million input tokens and $6 per million output tokens, versus Anthropic Opus 4.7 at $5 and $25; OpenAI’s Sol costs $5 and $30, while Luna matches Grok’s $6 output price.
Benchmark results released Wednesday suggested Grok 4.5 is competitive with top models but not clearly best-in-class, even as Musk said internal tests put it roughly on par with Opus 4.7.
The launch lands in a crowded week for frontier AI releases, with OpenAI expected to roll out GPT 5.6 on Thursday after earlier U.S. security-related limits.
