SpaceXAI’s New Code‑Guru: Grok 4. 5 Takes on Big Names

SpaceXAI has launched its latest AI model, Grok 4.5, following the acquisition of the coding startup Cursor for $60 billion. The new system targets long, complex tasks across software development, law, finance, and cybersecurity.

Public Debut: The launch coincides with SpaceXAI’s transition to a public tech firm, underscoring its mission to provide faster, cheaper coding solutions.
Token‑Efficient Design: Grok 4.5 claims to use fewer words for the same results, priced at $2 per million input tokens and $6 per million output tokens.
Anthropic: $5 / $25
OpenAI GPT‑5.6 Luna: $1 / $6
Availability: Accessible now via Grok Build, all Cursor plans, and SpaceXAI’s console. A full public release is slated for next Thursday, though EU access will be delayed.
Business Focus: Emphasizing “agentic work” (tasks requiring autonomous action on a user’s behalf), Grok 4.5 aims to win over finance clients. Musk noted the AI unit had lagged a year ago but has rebuilt its team to attract Wall Street customers.
Industry Context: OpenAI is preparing a broader rollout of GPT‑5.6 and new voice models, while regulators monitor AI safety. Cursor commits to blocking bad actors and supporting legitimate security research.
