<p id="speakable-summary" class="wp-block-paragraph">SpaceXAI has released its latest model, Grok 4.5 — the first since the company went public several weeks ago.</p>
<p class="wp-block-paragraph">In <a href="https://x.ai/news/grok-4-5" target="_blank" rel="noreferrer noopener nofollow">a blog post</a> published Wednesday, SpaceXAI characterized its new release as a workhorse that can tackle all of the typical tasks that the AI industry has sought to automate: coding and app-building, office and clerical work, research, writing, and other forms of routine knowledge work.</p>
<p class="wp-block-paragraph">Grok can supposedly do all this for less spend, too, as SpaceXAI says that its model has “twice greater token efficiency” than other leading models. If it carries through to real-world use cases, that efficiency would be a big advantage for SpaceXAI, since the cost of tokens has been a growing concern for AI consumers.</p>
<p class="wp-block-paragraph">The company released benchmark metrics Wednesday that appeared to show Grok’s competitiveness with other top models from SpaceXAI competitors, although just short of best-in-class:</p>

<p class="wp-block-paragraph">“Based on strong positive feedback from customers in our beta test program, @SpaceXAI will make Grok 4.5 available to the public tomorrow. It is an Opus-class model, but faster, more token-efficient and lower cost,” wrote Musk in his post on X.</p>
<p class="wp-block-paragraph"><a href="https://x.com/elonmusk/status/2074911038286295049?s=20" target="_blank" rel="noreferrer noopener nofollow">Musk later added</a>: “Our internal assessment is that Grok 4.5 is roughly comparable to Opus 4.7, but much faster. The combination of capability, faster speed and lower cost is what makes it competitive.”</p>
<p class="wp-block-paragraph">SpaceXAI says that its new model costs $2 per million input tokens and $6 per million output tokens. That’s quite competitive, if Grok’s capabilities match SpaceXAI’s rhetoric.</p>

OpenAI <a rel="nofollow" href="https://www.eesel.ai/blog/gpt-5-6-pricing">has tiered costs</a> for different model versions: Sol, its most expensive, costs $5 for 1 million input tokens and $30 for 1 million output tokens, while its least expensive, Luna, costs $1 for 1 million input and $6 for 1 million output tokens.</p>
<p class="wp-block-paragraph">It’s a big week for AI model releases. OpenAI is <a href="https://www.politico.com/news/2026/07/08/open-ai-models-release-sol-00989959" target="_blank" rel="noreferrer noopener nofollow">planning to release</a> GPT 5.6, its latest, most powerful model, on Thursday. The release of that model had previously been limited by the Trump administration, due to concerns about its security implications. OpenAI <a href="https://openai.com/index/previewing-gpt-5-6-sol/" target="_blank" rel="noreferrer noopener nofollow">has called it</a> its “strongest model yet.”</p>
