TechCrunch reported on Tuesday that SpaceXAI introduced Grok 4.5 as a general-purpose model for everyday knowledge work such as coding and app development, office and administrative tasks, research and writing.<\/p>\n<p>SpaceXAI cited cost efficiency as a strength of Grok 4.5. It highlighted that token efficiency is twice as high as other major models.<\/p>\n<p>Grok 4.5 is offered at $2 per 1 million input tokens and $6 per 1 million output tokens. Anthropic Opus 4.7 costs $5 per 1 million input tokens and $25 per 1 million output tokens. OpenAI&#8217;s prices vary by model. Sol, its most expensive model, costs $5 for input and $30 for output, while Luna, its cheapest, costs $1 for input and $6 for output.<\/p>\n<p>Benchmark metrics released by SpaceXAI show Grok 4.5 can compete with rivals&#8217; top models but falls slightly short of the very best, TechCrunch reported.<\/p>\n<p>Elon Musk (\uc77c\ub860 \uba38\uc2a4\ud06c) compared Grok 4.5 with Anthropic Opus on X (Twitter) and said, &#8220;Customer response to the beta test program was good.&#8221; He added, &#8220;Grok 4.5 is an Opus-class model, but it is faster, has higher token efficiency and costs less.&#8221;<\/p>\n","protected":false},"excerpt":{"rendered":"[Photo: Shutterstock] SpaceXAI has released a new AI model, Grok 4.5, for the first time since it listed.&hellip;\n","protected":false},"author":2,"featured_media":99640,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[10],"tags":[16191,6364,47109,157,19549,16817,2899],"class_list":["post-99639","post","type-post","status-publish","format-standard","has-post-thumbnail","category-xai","tag-anthropic-opus-4-7","tag-grok","tag-grok-4-5","tag-openai","tag-spacexai","tag-techcrunch","tag-xai"],"_links":{"self":[{"href":"https:\/\/www.europesays.com\/ai\/wp-json\/wp\/v2\/posts\/99639","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/ai\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/ai\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ai\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ai\/wp-json\/wp\/v2\/comments?post=99639"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/ai\/wp-json\/wp\/v2\/posts\/99639\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ai\/wp-json\/wp\/v2\/media\/99640"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/ai\/wp-json\/wp\/v2\/media?parent=99639"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/ai\/wp-json\/wp\/v2\/categories?post=99639"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/ai\/wp-json\/wp\/v2\/tags?post=99639"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
