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.

About

MiMo-V2.6-Flash is an open-source, natively omnimodal AI model from Xiaomi MiMo designed to balance intelligence, efficiency, and cost. The model supports coding, general agent workflows, visual reasoning, computer use, automation, and multimodal creative tasks. Its capabilities extend beyond software engineering into frontend design, presentation creation, 3D modeling, interactive world generation, video production, and embodied simulation. Xiaomi trained MiMo-V2.6-Flash with large-scale reinforcement learning across coding, general agent, visual, and cybersecurity tasks, completing roughly 750,000 training trajectories. The model is positioned as the more cost-efficient member of the MiMo-V2.6 family while retaining strong performance across software engineering, tool use, automation, and visual coding benchmarks. MiMo-V2.6-Flash is available through MiMo Desktop, AI Studio, MiMo Code, the Xiaomi MiMo API Platform, OpenRouter, and the open-source MiMo-V2.6 release.

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.

Pros & Cons from Real Users

Pros

  • What I like most is how much capability Xiaomi packed into a model this cheap. The 1M-token context window means I can use it for big repos, long documents, agent histories, and mixed-media workflows without constantly worrying about context limits. It is also genuinely useful beyond text. I can feed it images, video, audio, and text in the same workflow, which makes it a strong fit for agents, document processing, visual analysis, and automation.

Cons

  • The main downside is that I would still reach for MiMo-V2.6-Pro when I need maximum reasoning depth or I am working on something especially difficult or high-stakes. Flash feels more like the everyday workhorse.
