SpaceXAI Challenges Anthropic, OpenAI On Price<\/p>\n
The remark from Musk came just as SpaceXAI rolled out Grok 4.5, its latest AI model and the company\u2019s first major public release since going public. The launch was pitched as a major step for developers, engineers, coders, researchers, and other knowledge workers, but Musk\u2019s own comments have framed the model as a practical, cost-efficient challenger rather than the outright leader in the AI race.<\/p>\n
\u201cIn fairness, Fable is definitely better than Grok 4.5, but most tasks don\u2019t require Fable-level capability,\u201d Musk\u00a0said on X<\/a>. SpaceXAI\u00a0said<\/a> Grok 4.5 is a model \u201cbuilt for real-world engineering,\u201d saying it excels in large codebases and can handle long-running tasks across multiple repositories, hundreds of skills, and a variety of tools.<\/p>\n Musk\u00a0added<\/a> that the next release could mark another major leap, saying: \u201cNext month\u2019s release will be another step-change improvement, as we close the loop on solving real-world engineering problems at Tesla, SpaceX, Neuralink and Boring Company.\u201d<\/p>\n Musk earlier\u00a0called<\/a> Grok 4.5 an \u201cOpus-class model,\u201d\u00a0saying<\/a> it was comparable to Anthropic\u2019s Opus 4.7 but faster, more token-efficient, and lower-cost.\u00a0<\/p>\n SpaceXAI said Grok 4.5 is priced at $2 per million input tokens and $6 per million output tokens, making it cheaper than several rival high-end models if its performance holds up. Anthropic\u2019s Opus 4.7 costs $5 per million input tokens and $25 per million output tokens, while OpenAI\u2019s top-tier Sol model is priced at $5 per million input tokens and $30 per million output tokens. OpenAI\u2019s lower-cost Luna model is closer, at $1 for input and $6 for output.\u00a0<\/p>\n Benchmarks Put Grok 4.5 Behind Fable<\/p>\n SpaceXAI\u2019s launch benchmarks showed that Grok 4.5 performed strongly in some software engineering tests but trailed Anthropic\u2019s top models in others. On DeepSWE 1.1, which measures how reliably AI systems close real software bugs, Grok 4.5 scored 53%, behind Claude Opus 4.8, GPT-5.5, and Fable 5. On SWE Bench Pro, Grok 4.5 performed better, scoring 64.7%, ahead of GPT-5.5 but still behind Opus 4.8 and Fable 5.<\/p>\n Musk also said that Grok 4.5\u2019s current performance does not fully reflect SpaceXAI\u2019s hardware potential. \u201cGrok 4.5 is not yet using our internally developed C\/C++ inference software that exactly maps to the GB300 hardware,\u201d Musk\u00a0said on X<\/a>. \u201cDoubling or more of the current speed is probably achievable.\u201d The company trained Grok 4.5 using tens of thousands of Nvidia GB300 GPUs inside its Colossus supercomputer in Memphis, which reportedly has capacity across more than 200,000 GPUs.<\/p>\n Musk Says Grok 4.5 Will Improve Weekly<\/p>\n Musk further said that the pace of progress is accelerating, suggesting Grok 4.5 will improve rapidly after launch. \u201cRate of improvement is accelerating,\u201d Musk\u00a0said<\/a>. \u201cUsers should notice a meaningful improvement in the usefulness of the Grok Build harness with our V9 foundation model (aka Grok 4.5) every week.\u201d The weekly improvement claim may be important for SpaceX investors watching whether SpaceXAI can close the gap with Anthropic and OpenAI.<\/p>\n The Grok 4.5 launch comes during a crowded week for AI releases, with OpenAI preparing the public rollout of GPT-5.6 and Anthropic pushing ahead with its own powerful model lineup. Both companies are also moving toward public listings, making the race for enterprise AI dominance more intense.<\/p>\n How Do Retail Traders Feel About SPCX?<\/p>\n On Stocktwits, retail sentiment for SPCX was \u2018bearish\u2019 amid \u2018extremely low\u2019 message volume.<\/p>\n One user\u00a0said<\/a>, \u201c$SPCX I think this could get to $110-120 on a market pullback.\u201d<\/p>\n Another user\u00a0said<\/a>, \u201c$SPCX still too much hype!\u00a0 No data of the business until the first earnings report. So it\u2019s skeptical & speculation for now, imo. The company is valuation at $135 per share.\u201d<\/p>\n For updates and corrections, email newsroom[at]stocktwits[dot]com.<\/p>\n Read Next:\u00a0CMPS Stock Climbs After-Hours: Analyst Sees Depression Drug Approval By H1 2027 Or Sooner After Strong Trial Data\u00a0<\/a><\/p>\n![\"spcx](\"https:\/\/www.europesays.com\/people\/wp-content\/uploads\/2026\/07\/spcx_ss_png_cdd37d6fe6.webp\")
