Composer 1 Description
Composer is an AI model crafted by Cursor, specifically tailored for software engineering functions, and it offers rapid, interactive coding support within the Cursor IDE, an enhanced version of a VS Code-based editor that incorporates smart automation features. This model employs a mixture-of-experts approach and utilizes reinforcement learning (RL) to tackle real-world coding challenges found in extensive codebases, enabling it to deliver swift, contextually aware responses ranging from code modifications and planning to insights that grasp project frameworks, tools, and conventions, achieving generation speeds approximately four times faster than its contemporaries in performance assessments. Designed with a focus on development processes, Composer utilizes long-context comprehension, semantic search capabilities, and restricted tool access (such as file editing and terminal interactions) to effectively address intricate engineering inquiries with practical and efficient solutions. Its unique architecture allows it to adapt to various programming environments, ensuring that users receive tailored assistance suited to their specific coding needs.

Engineering teams shipping with AI have a new bottleneck: validation. Code output has accelerated. Quality hasn't. Checksum closes the gap.
Checksum is a continuous quality platform with a suite of AI agents that handle testing end-to-end, at every stage of the development lifecycle. Where most tools wait for a human to trigger them, Checksum runs autonomously in the background, generating tests, executing them, and repairing failures without manual intervention. Seventy percent of test failures are resolved automatically through real-time auto-recovery.
The platform covers every layer: end-to-end UI flows via Playwright, API endpoint chains, and targeted CI tests scoped to exactly what changed in a PR. All tests land as real code in your repository and are delivered as standard Playwright, owned by your team.
Checksum is fine-tuned on 1.5+ million test runs and integrates natively with Cursor, Claude Code, and 100+ AI coding agents. Type /checksum and your coding agent's output gets tested before it ever reaches review. Generation and healing happen on Checksum's cloud infrastructure which means no LLM tokens consumed, no local resources required.
The result: test suites that stay green as the product evolves, fewer regressions reaching production, and release confidence that scales alongside AI output.

Screencapt allows you to record the entire screen or a selected area. You can also record a specific window. Screencapt is the ideal screen recorder because of its flexibility. Using the integrated audio recording you can also add your commentary or system sound directly into the screen recording. This is particularly useful when creating explanation videos or presentations.
Screencapt's ability to record a webcam is a special feature. You can now add your comments and reactions to the video. This makes your screen recordings more personal and professional.
Screencapt offers advanced options to record the cursor. You can choose to hide the cursor or add special effects to highlight specific actions. This is especially useful for software tutorials and demonstrations where a clear cursor view is required.

Grok 4.5
Grok 4.5 is SpaceXAI’s smartest model, designed to excel at coding, agentic workflows, engineering tasks, and knowledge work. The model was trained on large-scale datasets covering coding, science, engineering, and math, with additional reinforcement learning focused on multi-step software engineering. It is built to perform well on real engineering workflows, including debugging, terminal-based tasks, complex code generation, Rust and C/C++ development, and app building from minimal prompts. Grok 4.5 is served at fast-model speeds while using fewer output tokens on comparable coding tasks, helping teams complete technical work more quickly and cost-effectively. The model is also available in Grok Build, where it can help create Excel models, PowerPoint presentations, Word documents, diagrams, business review decks, and research-supported productivity assets. Developers can access Grok 4.5 through the SpaceXAI API, Cursor, and Grok Build, with simple API key setup and support for direct integration into coding and automation workflows. Its pricing is positioned for high-intelligence work at scale, with per-million-token rates for both input and output usage. Grok 4.5 is also trained for agentic execution, allowing it to handle longer technical rollouts and multi-step problem solving more effectively. For developers, engineering teams, and knowledge workers, Grok 4.5 provides a powerful AI model for software creation, office automation, technical reasoning, and production-grade agent workflows.

Grok 4.7
Grok 4.7 is SpaceXAI’s advanced AI model for software development, professional knowledge work, and multi-step agentic tasks. It is built on a larger base model than Grok 4.6 and uses a longer reinforcement learning training run weighted toward difficult problems that require extended execution time. The model is better at checking its own work, maintaining longer context, and completing complex workflows that span many steps. Native support for the Grok Bot harness improves its conversational abilities and makes it more capable across general knowledge and interactive work. Grok 4.7 is positioned for use in coding, terminal automation, legal workflows, document and presentation creation, electrical engineering, healthcare reasoning, and other professional tasks. SpaceXAI also reports improvements across software engineering benchmarks including CursorBench and DeepSWE as well as professional-work evaluations such as AA Briefcase. The model includes a redesigned safety system intended to improve refusal behavior, jailbreak resistance, and handling of potentially dangerous cybersecurity and biological requests. Developers can access Grok 4.7 through Grok Build, Cursor, the Grok API, third-party coding tools, cloud providers, and model-routing platforms. Grok 4.7 is priced starting at $2 per million input tokens and $6 per million output tokens, with a faster variant available at a higher price.
