About
Campfire SMS is a hosted, two-way SMS bridge for developers who use AI coding agents. It connects an agent running in a local session—or a configured cloud agent—to a verified phone number, sending task updates and questions to the user’s regular text inbox and passing replies back to the agent. The service supports MCP-compatible clients, with setup instructions for Codex, Claude Code, Cursor, Grok Build, OpenCode, and Grok Bot. Local agents require the computer and session to remain active; configured Grok Bot routines can run in the cloud while the computer is off. Users can receive build or test completion notices, respond to agent questions, and guide ongoing coding work away from the desk. SMS delivery uses a hosted account and message credits; the agent’s own model, tools, and task execution remain in the agent environment.

About
Grok 4.5 is SpaceXSI’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 SpaceXSI API console, Grok 4.5 gives developers and teams a high-performance model for building software, automating work, and more.
