However, Elon Musk\u2019s SpaceXAI (previously xAI) had been trailing behind the two AI labs when it came to coding or other tasks such as finance and legal services with its own AI model, Grok. Now, SpaceXAI has unveiled Grok 4.5 \u2013 its most advanced AI model \u2013 built with the AI coding platform Cursor.<\/p>\n<p>As per SpaceXAI, Grok 4.5 is its strongest AI model ever, and built to handle a variety of things \u2013 be it coding, agentic tasks or knowledge work. The company says that Grok 4.5 can also be used for business work, such as finance or legal services, <a href=\"https:\/\/www.indiatoday.in\/technology\/news\/story\/anthropic-wants-claude-to-be-your-lawyer-launches-plugins-for-legal-work-2910885-2026-05-13\" target=\"_blank\" rel=\"nofollow noopener\">something also offered by Anthropic with Claude<\/a>.<\/p>\n<p>According to tech trillionaire Elon Musk, Grok 4.5 can match Anthropic\u2019s Claude Opus 4.7 model, but it is \u201cmuch faster.\u201d He added, \u201cThe combination of capability, faster speed and lower cost is what makes it competitive.\u201d<\/p>\n<p>Elon Musk compared Grok 4.5 to Anthropic&#8217;s Opus 4.7 model.\n<\/p>\n<p>Do note that Grok 4.5 is the first joint model from SpaceXAI and Cursor, and its launch comes weeks after SpaceX formally agreed to acquire Cursor in a <a href=\"https:\/\/www.indiatoday.in\/technology\/news\/story\/days-after-ipo-spacex-moves-to-buy-ai-coding-startup-cursor-for-60-billion-2927897-2026-06-16\" target=\"_blank\" rel=\"nofollow noopener\">deal valuing the startup at $60 billion<\/a>.<\/p>\n<p>  What can Grok 4.5 do?<\/p>\n<p>In a blog post on Wednesday, SpaceXAI said Grok 4.5 was designed to \u2018handle difficult, long-running tasks\u2019, especially in software engineering, while also extending to legal and financial work.<\/p>\n<p>The company used the launch to show examples of <a href=\"https:\/\/www.indiatoday.in\/technology\/features\/story\/ai-101-for-dummies-use-this-guide-to-talk-smartly-about-ai-at-work-so-you-dont-get-fired-2916210-2026-05-24\" target=\"_blank\" rel=\"nofollow noopener\">one-prompt app building<\/a>, including a Three.js solar system simulation with adjustable time and realistic motion. It also said Grok 4.5 is now the default model in Grok Build and can create complex Excel models using web research and multi-sheet formulas, leave notes for later reference, build diagrams in PowerPoint and write clear prose in Word.<\/p>\n<p>An example of a one-shot project made with Grok 4.5 (Photo: SpaceXAI).<\/p>\n<p>SpaceXAI also shared benchmark scores for Grok 4.5. In AI coding benchmark DeepSWE 1.0, the model outperformed Anthropic\u2019s Opus 4.8, and stood right behind OpenAI\u2019s GPT-5.5. Grok 4.5 was trained across tens of thousands of highly-advanced Nvidia GB300 GPUs.<\/p>\n<p>Grok 4.5 can find cybersecurity flaws<\/p>\n<p>The SpaceXAI model also comes with increased cybersecurity capabilities. Cursor said it had taken steps to \u201cdetect and block bad actors\u201d while seeking to \u201cpreserve legitimate security work, including finding and patching vulnerabilities, while restricting the workflows most likely to cause harm.\u201d<\/p>\n<p>This comes at a time when the US government had previously <a href=\"https:\/\/www.indiatoday.in\/technology\/features\/story\/explained-why-us-govt-banned-indians-all-foreigners-from-using-anthropic-claude-fable-5-mythos-2926023-2026-06-13\" target=\"_blank\" rel=\"nofollow noopener\">limited access to modliels like Claude Fable 5<\/a> and GPT-5.6 due to concerns over cybersecurity capabilities. Though the US has allowed the general release for both models since then.<\/p>\n<p>The release is part of a broader effort by Musk\u2019s company to catch up in the AI race and win more business customers. Elon Musk had said earlier this year that his AI startup, known as xAI before it merged with SpaceX, had fallen behind on coding, leading to staffing changes.<\/p>\n<p>SpaceXAI released its first coding agent in May to compete with Anthropic\u2019s products. Grok 4.5 is now available in Grok Build, in Cursor on all plans and through the SpaceXAI console, though it is not yet available in the European Union.<\/p>\n<p>The company has priced it at $2 (roughly Rs 190) per million input tokens and $6 (roughly Rs 570) per million output tokens, lower than Claude Opus 4.8 at $5 (roughly Rs 480) and $25 (roughly Rs 2390) respectively, while OpenAI\u2019s GPT 5.6 Terra is priced at $2.5 (roughly Rs 240), and $15 (roughly Rs 1430) respectively.<\/p>\n<p>&#8211; Ends<\/p>\n<p>Published By: <\/p>\n<p>Armaan Agarwal<\/p>\n<p>Published On: <\/p>\n<p>Jul 9, 2026 09:32 IST<\/p>\n","protected":false},"excerpt":{"rendered":"The AI race has intensified in recent months as Anthropic and OpenAI continue to make advancements when it&hellip;\n","protected":false},"author":2,"featured_media":99867,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[10],"tags":[32167,2406,9722,38372,140,52046,6364,47109,24313,11360,19549,2899],"class_list":["post-99866","post","type-post","status-publish","format-standard","has-post-thumbnail","category-xai","tag-ai-coding-model","tag-claude-opus","tag-cursor-acquisition","tag-cybersecurity-capabilities","tag-elon-musk","tag-finance-and-legal-ai","tag-grok","tag-grok-4-5","tag-grok-build","tag-openai-gpt-5-5","tag-spacexai","tag-xai"],"_links":{"self":[{"href":"https:\/\/www.europesays.com\/ai\/wp-json\/wp\/v2\/posts\/99866","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=99866"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/ai\/wp-json\/wp\/v2\/posts\/99866\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ai\/wp-json\/wp\/v2\/media\/99867"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/ai\/wp-json\/wp\/v2\/media?parent=99866"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/ai\/wp-json\/wp\/v2\/categories?post=99866"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/ai\/wp-json\/wp\/v2\/tags?post=99866"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
