Extracted system prompts from ChatGPT (GPT-5.5 Thinking), Claude (Opus 4.7, Opus 4.6, Sonnet 4.6, Claude Code), Gemini (3.1 Pro, 3 Flash, Gemini CLI), Grok (4.3 beta), Perplexity, and more. Updated regularly.

Unique: Aggregates system prompts from 8+ providers in a structured format that enables direct architectural comparison. Reveals how different providers implement solutions to common problems (tool calling, memory, safety, personality) using different system-level approaches.

vs others: Unique in enabling side-by-side architectural comparison across providers; most analysis is scattered across individual provider documentation or blog posts.

via “llm foundations and architecture conceptual framework”

A one stop repository for generative AI research updates, interview resources, notebooks and much more!

Unique: Organizes foundational concepts with explicit connections to practical implications and research papers, rather than just explaining components in isolation. Includes visual explanations and intuitive descriptions alongside mathematical formulations.

vs others: More pedagogically structured than academic papers; provides progressive learning from intuitive concepts to mathematical details, whereas most foundational resources either oversimplify or assume advanced mathematical background.

via “llm architecture visualization”

LLM Architecture Gallery

Unique: Focuses on visual and comparative aspects of LLM architectures rather than just textual descriptions, enhancing user understanding through graphical representations.

vs others: More visually oriented and user-friendly than traditional academic papers or documentation, making it easier for non-experts to grasp complex architectures.

via “llm-deployment-and-infrastructure-patterns”

Course to get into Large Language Models (LLMs) with roadmaps and Colab notebooks.

Unique: Provides dedicated deployment section with coverage of containerization, orchestration, cloud platforms, and operational considerations. Links to both deployment frameworks and cloud documentation, enabling practitioners to deploy models across different infrastructure options.

vs others: More LLM-specific than generic DevOps guides; more practical than research papers because it includes tool recommendations and architecture patterns

via “conceptual mapping of llm functionalities”

All content is based on Andrej Karpathy's "Intro to Large Language Models" lecture (youtube.com/watch?v=7xTGNNLPyMI). I downloaded the transcript and used Claude Code to generate the entire interactive site from it — single HTML file. I find it useful to revisit this content time

Unique: Combines interactive visualization with functional mapping, allowing users to see the relationship between architecture and practical applications in a way that static diagrams cannot.

vs others: More integrated and user-friendly than traditional flowcharts or static diagrams, enhancing user engagement and understanding.

via “llm integration framework”

This tool is a cutting-edge memory engine that blends real-time learning, persistent three-tier context awareness, and seamless LLM integration to continuously evolve and enrich your AI’s intelligence.

Unique: Features a modular architecture that allows for easy integration and switching between various LLMs without code changes.

vs others: More flexible than static integration solutions, allowing for dynamic model selection based on user needs.

via “multi-language code pattern recognition”

Compact, language-agnostic codebase mapper for LLM token efficiency.

Unique: Uses heuristic matching on structural graph properties (function signatures, call chains, class hierarchies) rather than semantic analysis, enabling pattern detection across languages while remaining computationally lightweight and not requiring language-specific tooling

vs others: More portable than language-specific linters or static analysis tools because it works across polyglot codebases, and more practical than manual code review because it automates pattern detection at scale

via “multi-provider llm abstraction layer”

Forge LLM SDK

Unique: unknown — insufficient data on whether Forge uses adapter pattern, factory pattern, or strategy pattern for provider switching; no documentation on how response normalization is implemented

vs others: unknown — insufficient data on performance characteristics, provider coverage, or feature parity compared to LangChain, Vercel AI SDK, or direct provider SDKs

via “multi-llm api orchestration”

MCP server: auto_llm_routing

Unique: Utilizes a centralized API gateway for managing multiple LLMs, which reduces the complexity of direct API interactions compared to decentralized approaches.

vs others: Offers a more streamlined integration process than traditional multi-API management solutions.

via “architecture and design pattern suggestions”

Qwen2.5-Coder-Artifacts — AI demo on HuggingFace

Unique: Qwen2.5-Coder suggests patterns by understanding code intent and structure, not just applying mechanical transformations, enabling recommendations that improve both design and implementation

vs others: More contextually aware than pattern documentation because it analyzes actual code and recommends patterns that fit the specific use case, whereas documentation provides generic pattern descriptions

via “architectural design and system design reasoning”

GLM-5.1 delivers a major leap in coding capability, with particularly significant gains in handling long-horizon tasks. Unlike previous models built around minute-level interactions, GLM-5.1 can work independently and continuously on...

Unique: Reasons about system-level design decisions and tradeoffs using knowledge of architectural patterns and scalability principles, providing guidance beyond code-level optimization

vs others: Provides more thoughtful architectural guidance than generic LLMs because it's trained on coding tasks and understands implementation implications of design decisions

via “llm application architecture patterns and system design”


Unique: Covers complete application architecture from high-level patterns through operational concerns, with explicit focus on production considerations and integration with existing systems. Treats LLM applications as complete systems rather than just adding an LLM to existing code.

vs others: More comprehensive than most LLM application guides, covering architectural patterns and system design while remaining more practical than academic software architecture research


Unique: Provides systematic framework for choosing between agent architectures, pipelines, and hybrid approaches — not just 'use an agent' but 'when agents are appropriate and what trade-offs they involve.' Includes case studies of real systems.

vs others: More strategic than framework documentation; includes architectural trade-offs and decision frameworks that help teams avoid over-engineering or under-engineering LLM systems.

via “modular-component-composition-with-reusable-abstractions”


Unique: unknown — handbook repeatedly emphasizes 'modularity and composability' but provides no code examples, design patterns, or architectural diagrams showing how components are actually composed

vs others: unknown — no comparison to other modular LLM frameworks or architectural approaches

via “multi-provider-llm-abstraction”

Build better language model apps, fast.

via “ml system architecture decision-making and trade-off analysis”


Unique: Provides explicit frameworks and heuristics for making architectural decisions by analyzing trade-offs, rather than presenting architectural patterns in isolation or assuming a single 'correct' approach.

vs others: More systematic than pattern-based architectural guidance; more practical than academic systems design research which may not address real-world constraints and trade-offs

via “llm provider abstraction with unified model interface”


Unique: unknown — insufficient data on whether LangChain uses adapter pattern, factory pattern, or strategy pattern for provider abstraction; specific implementation details not documented in course materials

vs others: Provides unified interface across more LLM providers than most frameworks, but abstraction layer overhead and potential feature loss compared to direct provider API calls

via “hands-on llm system design and implementation guidance”

in Large Language Models.

Unique: Mentorship from active LLM researchers at CMU who have built production systems, providing guidance informed by real-world engineering challenges and recent research insights rather than generic software engineering principles

vs others: Offers personalized feedback and expert guidance unavailable in self-paced online courses, though requires synchronous engagement and is limited to enrolled students

via “llm-based system architecture education and curriculum delivery”

in AI System.

Unique: unknown — insufficient data on specific pedagogical approach, content organization strategy, or differentiation from other LLM education resources

vs others: unknown — insufficient data on how this Notion-based curriculum compares to alternatives like university courses, online platforms (Coursera, Udacity), or other LLM system design resources
