SpaceXAI Releases Grok 4.5, an 'Opus-class' Model
SpaceXAI has publicly released Grok 4.5, its first major model update since the company went public. SpaceXAI positions Grok 4.5 as a general-purpose workhorse for coding, writing, research and other knowledge work, and claims the model delivers roughly "twice greater token efficiency" than other leading models. The company published benchmark metrics showing competitive performance and announced pricing at $2 per million input tokens and $6 per million output tokens. Elon Musk posted that Grok 4.5 is "an Opus-class model" and said SpaceXAI's internal assessment finds it roughly comparable to Anthropic's Opus 4.7 but faster. The article notes contemporaneous AI activity, including OpenAI's planned release of GPT 5.6.
A competitive, lower-cost LLM release with claimed higher token efficiency could pressure pricing and total cost of ownership for AI deployments and influence model-choice dynamics across industries that consume large token volumes.

SpaceXAI Rolls Out Grok 4.5 for Coding and Agents
SpaceXAI has released Grok 4.5, an LLM positioned for coding and agentic tasks that the company says was co‑trained with the coding agent Cursor and benefits from SpaceXAI infrastructure plans such as the Colossus datacenter (and longer‑term satellite datacenter ambitions). SpaceXAI claims Grok 4.5 runs at about 80 transactions per second (TPS), uses fewer tokens than some competitors on comparable tasks, and is priced at $2 per million input tokens and $6 per million output tokens. The model is available now via Grok Build, Cursor subscriptions and the SpaceXAI Console (EU rollout scheduled for mid‑July). SpaceXAI compares Grok 4.5 to models from OpenAI and Anthropic and highlights integrations in tools such as Notion, Warp, OpenCode and OpenClaw.
xAI launches Grok 4.5 Opus-class coding model
xAI (branded in the article as SpaceXAI) publicly launched Grok 4.5, a coding-and-agent-focused foundation model trained in partnership with Cursor. The release positions Grok 4.5 as an “Opus-class” model optimized for cost, speed and token efficiency rather than absolute benchmark dominance. Public details include a reported model scale of 1.5 trillion parameters (3x larger than Grok 4.3), an official list price of $2 per 1M input tokens and $6 per 1M output tokens, and an initial context window reported at 500k tokens with intentions to restore 1M soon. Third-party evaluations from Artificial Analysis rank Grok 4.5 near the frontier on capability while highlighting efficiency advantages for coding/agent workloads. Cursor announced immediate product availability and promotional usage for early adopters.
Grok 4.7 Launch: SpaceXAI Enhances Coding, Safety
SpaceXAI has released Grok 4.7, a new AI model focused on software development, knowledge work, and long-horizon tasks. Built on a larger foundation than Grok 4.6 and refined through extended reinforcement learning, it improves context management and output verification. Grok 4.7 scores 46 on the Artificial Analysis Intelligence Index, ranking fourth among frontier labs, and surpasses GPT-5.6 Sol on the Coding Agent Index. It also achieves strong results on CursorBench, DeepSWE, Terminal-Bench, and shows a 111 Elo improvement on AA-Briefcase. The model uses 125% more tokens per task, increasing compute costs. New safety features include a new safety stack that allows only 3.3% risky dual-use requests on HackerBench v0.3, improved malicious request rejection, and invite-only red-team access for cybersecurity partners. Grok 4.7 is available via Cursor, Grok Build, and the Grok API at unchanged pricing, with a faster variant exclusive to Cursor and Grok Build at double the cost.
