The free cloud coding agent with multi-model intelligence
Production code architecture for any repository, a free multi-model agent, and an instant live preview — $0/yr.
Autonomous Multi-Agent Intelligence
Supercharged multi-model intelligence, deep architectural reasoning, real-time web research, and interactive data visualization. No paywalls. No closed gardens.
Unlike chatbots that only talk, Cortex Agent 5.3 operates like a staff principal engineer. It breaks down prompts into autonomous sub-tasks, performs real-time web research, synthesizes production-grade code architectures, renders interactive charts, and packages deliverable markdown artifacts.
Everything you need to analyze datasets, research topics live on the web, engineer production architectures, and build deliverables.
Switch seamlessly between Cortex 5.3 (Frontier MoE 753B), Cortex 5.3 Flash (Vision & Reasoning 320B), Cortex 5 (Super Agent 120B), Cortex 5 Ultra (Master Agent 550B), and Cortex 4 (Deep Reasoning).
Instant live HTML, CSS, JavaScript, and Mermaid rendering in an interactive split preview panel with 1-click downloads.
Autonomous DuckDuckGo web search, full-text URL content scraping, live weather telemetry, and Wikipedia fact-checking.
Real-time mathematical formula rendering with automatic normalization for instant copy-paste into Notion & Obsidian.
Generate responsive Chart.js visualizations directly from raw CSV or JSON data with zero external dependencies.
PBKDF2 salted credentials, signed HMAC session tokens, and durable SQLite WAL storage. Your prompts remain yours alone.
Switch seamlessly across specialized intelligence tiers engineered for autonomous coding, exhaustive reasoning, vision, and ultra-fast generation.
Colossal 753B parameter frontier flagship locked into Deep Thinking mode for profound mathematical proofs and repo architecture.
High-speed 320B multimodal & vision reasoning model with instantaneous first-token response and locked deep thinking.
Premier autonomous coding & tool orchestration engine paired with LangChain agent loop.
Massive 550B frontier model for exhaustive multi-chapter PRDs, architecture specifications, and deep research.
Specialized chain-of-thought logic engine optimized for complex algorithms, math proofs, and bug root cause isolation.
High-resolution multimodal model that inspects UI screenshots, architecture diagrams, and charts in real time.
Ultra-low-latency streaming engine built for instant autocomplete, rapid code formatting, and iterative queries.
Production code architecture for any repository, a free multi-model agent, and an instant live preview — $0/yr.
Why paying $240/yr for closed vendor lock-in is obsolete when open-weight NIM inference delivers sub-second results.
Inside Cortex's distributed streaming pipeline, real-time math normalization, and interactive client artifacts.
Everything you need to know about Cortex Agent 5.3 architecture, security, and models.
Cortex is powered directly by high-throughput NVIDIA NIM cloud infrastructure and client-side artifact rendering. By bypassing cloud subscription markups, Cortex delivers frontier reasoning and execution without charging you a cent.
You have instant access to 7 active frontier models: Cortex 5.3 (Frontier MoE 753B), Cortex 5.3 Flash (Vision & Reasoning 320B), Cortex 5 (Super Agent 120B), Cortex 5 Ultra (Master Agent 550B), Cortex 4 (Deep Reasoning), Cortex 4 Omni (Vision & Reasoning), and Cortex 3.5 Lightning (Ultra-Fast).
Never. Your chats, prompts, uploaded files, and generated artifacts are stored securely in your private session database with salted PBKDF2 credentials. No user data is ever sold or used for model training.
Yes! Cortex includes a dedicated split-view artifact studio. Web apps, Chart.js graphs, KaTeX math formulas, and Mermaid diagrams render interactively in real time with 1-click downloads.
No credit card or API key is required. Simply register your free account in seconds and immediately begin chatting, analyzing, and building.
Cortex provides equivalent or superior reasoning capabilities without monthly $20 subscription fees, restrictive messaging quotas, or locked proprietary silos.
Yes! Cortex has automated math syntax normalization built right into its copy and download handlers. Formulas exported as Markdown render seamlessly in Notion, Obsidian, and Typora.
Every piece of code generated in Cortex is standalone and clean. You can download the files as a bundle or individual artifacts and deploy them directly to Vercel, Netlify, or any static host.
Stop paying $20/month for closed AI silos. Launch Cortex and experience the future of autonomous workflows.
