SpaceX releases Grok 4.5, first model built alongside Cursor
SpaceX (NASDAQ:SPCX) released Grok 4.5, its first major AI model update built with Cursor for coding and agentic workflows. The 1.5T-parameter model was trained on tens of thousands of GB300 GPUs and follows Grok 4.3. SpaceX cites improved benchmark performance and lower pricing, $2 per 1M input tokens and $6 per 1M output. UBS reiterated a Buy and $210 target.
How this was made
The 30-second read
Why it matters
Grok 4.5’s lower token pricing and improved efficiency versus Opus and prior Grok versions are positioned as a step toward enterprise AI scale, supported by UBS’s Buy rating and sum-of-the-parts valuation.
Market read
Traders get a concrete product-and-pricing update plus a same-article analyst valuation anchor, which can shift sentiment around SpaceX’s enterprise AI momentum.
What to watch
Competitive responses from OpenAI and Anthropic (e.g., upcoming GPT 5.6) could quickly narrow differentiation, and enterprise adoption cycles may lag model releases.
Background
The article frames Grok 4.5 as SpaceX’s first major update built alongside Cursor, following Grok 4.3’s April 2026 launch.
Ticker impact
SpaceX released Grok 4.5, a major AI model update built with Cursor, with new pricing and efficiency metrics for enterprise coding workflows.
Near-term sentiment positive; magnitude likely limited without disclosed customer traction or financial guidance.
The text includes concrete product specs (token pricing, efficiency vs Grok 4.3, benchmark claims) and a UBS Buy/PT, but lacks disclosed enterprise customer wins or financial impact.
Market effects
Reinforces competitive pressure in enterprise AI for coding and agentic workflows, emphasizing cost-per-token efficiency as a differentiator.
No specific regional market catalyst beyond general AI sentiment.
Competitive benchmark-setting against major AI labs (Claude, OpenAI) may influence global enterprise AI procurement expectations.
Counterpoint
Benchmark and pricing claims may not translate into near-term enterprise revenue; without disclosed customer adoption, the market may discount the impact.
