- Grok 4.5 is released in collaboration with SpaceXAI as the most intelligent model, designed for tasks beyond software engineering.
- It can handle difficult, long-running tasks in various fields like software engineering, data science, finance, and legal work by creatively using tools.
- Cursor subscription plans include significant model usage with double usage for the first week and added safeguards for cybersecurity.
- Grok 4.5 is a mixture-of-experts model trained with trillions of tokens from Cursor data, learning from software and developer-agent interactions.
- Training data was broadened to include high-quality STEM tasks, research papers, and knowledge work for proficiency across domains.
- Reinforcement learning was applied in realistic environments to teach problem investigation, tool usage, error recovery, and result verification.
- A distributed agent system scaled environment construction, using previous models to accelerate progress on difficult problems.
- Grok 4.5 is available on multiple platforms with pricing at $2/M input tokens and $6/M output tokens, and a fast variant at higher rates.
- Grok 4.5 and Composer 2.5 will both be supported, with future models planned for the Composer size.
