💥 Tokenade Generator Advanced token stress-testing tool for LLMs and tokenizers

What is a Tokenade? A "token grenade" - a compact payload that explodes into thousands of tokens when processed by language models. Perfect for:

🧪 Stress-testing LLM tokenizers and context limits
🔍 Research into model behavior with dense token inputs
🛡️ Security testing of systems that process user text
⚡ Performance analysis of text processing pipelines

How it works: Combines emojis with invisible Unicode characters (zero-width joiners, variation selectors) in nested structures that tokenize inefficiently, creating massive token expansion from minimal visible text.

DISCLAIMER: Tokenade payloads can severely degrade model performance and crash UIs. Use for testing only. Do not deploy to production or target systems without explicit permission.

Danger zone: Estimated length {{ estimateTokenadeLength().toLocaleString() }} chars exceeds the safe threshold ({{ dangerThresholdTokens.toLocaleString() }}). Generating this will very likely freeze/crash your browser or downstream tools. Proceed only if you fully understand the risks.

🔢 Depth (nesting levels) {{ tbDepth }} level{{ tbDepth > 1 ? 's' : '' }} Creates nested emoji structures 📏 Breadth (items per level) {{ tbBreadth }} item{{ tbBreadth > 1 ? 's' : '' }} Width of each nesting level 🔁 Repeats (duplicate blocks) {{ tbRepeats }} block{{ tbRepeats > 1 ? 's' : '' }} Repeat entire structure N times

🎨 Variation Selectors VS16/VS15 for token churn 🌊 Invisible Noise Random zero-width chars Auto-copy

📊 Estimated length: {{ estimateTokenadeLength().toLocaleString() }} characters
💡 Pro tip: Length grows multiplicatively - doubling depth/breadth can 4x the size!

🎯 Single Carrier Mode: Hides the entire tokenade payload inside invisible "emoji tag sequences" attached to one visible emoji. The emoji acts as a Trojan horse - looks innocent but contains massive token payload!

🚀 Quick picks - Choose your carrier emoji:

📦 Single emoji carrier mode Steganographic mode: all data hidden in one emoji Carrier Advanced: custom carrier text When set, this overrides quick picks and dropdown.

✅ Generated: {{ tokenBombOutput.length.toLocaleString() }} characters
⚠️ Warning: This payload may consume massive tokens when processed by LLMs!
🧪 Use case: Perfect for testing tokenizer limits and model robustness

Mutation Lab Advanced payload fuzzing with multiple mutation strategies

🔬 What is Mutation Lab? A comprehensive fuzzing tool that applies multiple chaotic mutations to your base text, creating diverse test payloads for security research and robustness testing.

🆚 Randomizer vs Mutation Lab:

🎲 Randomizer: Applies different transforms to each word (Base64 + Elder Futhark + Morse, etc.)
🧬 Mutation Lab: Applies multiple chaos mutations to the entire text (Unicode noise + Zalgo + whitespace chaos, etc.)

Base text Cases Repeats per case Seed (optional)

Random Mix (transforms) Zero‑width pepper Unicode noise Zalgo Whitespace chaos Casing chaos Homoglyph confusables

🔀 Bijection Attack Generator Custom encoded languages for AI safety research

🧠 What is Bijection Learning? A sophisticated jailbreaking technique that creates custom character mappings to bypass AI safety mechanisms. The model learns to communicate in your encoded language, potentially circumventing built-in guardrails.

🎯 Research by Haize Labs:

🔬 Scale-agnostic: More effective on advanced models
📊 86.3% success rate on Claude 3.5 Sonnet
🎯 Best-of-N attacks: Multiple attempts with budget management

📄 Source: Endless Jailbreaks with Bijection Learning - Haize Labs

🔤 Bijection Type How characters are transformed 🎯 Fixed Size (unchanged chars) {{ bijectionFixedSize }} char{{ bijectionFixedSize !== 1 ?

🎲 Randomizer - Code Switching Magic!

🌟 Code-switching magic! Apply different transforms to each word in your sentence, creating a polyglot mix of encodings. Each word gets a random encoding (Base64, Elder Futhark, Morse, etc.) for maximum confusion.

🎯 Generate Multiple Cases:

Cases Repeats per case Seed (optional)

#{{ i+1 }}

🎮 How it works:

🔀 Each word gets a random transform
🎯 Mixes fantasy, ancient, and modern encodings
📝 Preserves punctuation and spacing
🔍 Check console for transform mapping details

Example: "Hello World!" → "SGVsbG8= ᚹᚩᚱᛚᛞ!"
