About

GLM-5 is Z.ai’s latest large language model built for complex systems engineering and long-horizon agentic tasks. It scales significantly beyond GLM-4.5, increasing total parameters and training data while integrating DeepSeek Sparse Attention to reduce deployment costs without sacrificing long-context capacity. The model combines enhanced pre-training with a new asynchronous reinforcement learning infrastructure called slime, improving training efficiency and post-training refinement. GLM-5 achieves best-in-class performance among open-source models across reasoning, coding, and agent benchmarks, narrowing the gap with leading frontier models. It ranks highly on evaluations such as Vending Bench 2, demonstrating strong long-term planning and operational capabilities. The model is open-sourced under the MIT License.

About

Grok 4.5 is SpaceXAI’s advanced AI model built for coding, agentic tasks, engineering work, and knowledge-intensive productivity. The model is trained on coding, science, engineering, and math data, with reinforcement learning focused on multi-step software engineering and technical workflows. It is designed to handle real-world development tasks such as debugging, Rust and C/C++ work, terminal tasks, long-running agentic rollouts, and end-to-end app creation from a single prompt. Grok 4.5 is also built for fast serving, token efficiency, and lower-cost execution, with pricing based on input and output token usage. Beyond coding, the model supports business productivity tasks in Grok Build, including Excel modeling, PowerPoint diagram creation, Word writing, and research-assisted office workflows. Available through Grok Build, Cursor, and the SpaceXAI API console, Grok 4.5 gives developers and teams a high-performance model for building software, automating work, and more.

Pros & Cons from Real Users

Pros

  • Grok 4.5 is really impressive from the perspective of a developer and AI agent builder. It feels built for the stuff I actually care about: coding, tool use, agentic workflows, debugging, refactoring, and getting real work done instead of just chatting. I especially like that it seems focused on speed and cost efficiency, because those two things matter a lot when you are running agents over and over in production-like workflows.

Cons

  • It still feels early, and I would want to test it hard before trusting it as the backbone of serious production agents. Benchmarks and launch claims are useful, but they do not always translate perfectly into messy real-world codebases, weird edge cases, long-running tasks, and tool-heavy workflows. I also want to see how reliable it is across longer sessions, especially when an agent has to stay on track through multiple steps without drifting.
