system_prompts_leaksModel43/100 via “personality and behavioral framework documentation”
Extracted system prompts from ChatGPT (GPT-5.4, GPT-5.3, Codex), Claude (Opus 4.6, Sonnet 4.6, Claude Code), Gemini (3.1 Pro, 3 Flash, CLI), Grok (4.2, 4), Perplexity, and more. Updated regularly.
Unique: Documents GPT-5's explicit personality framework with three distinct variants (Listener, Nerdy, Cynic) and their specific behavioral constraints, plus Grok's persona and companion system. Shows how personality is implemented at the system prompt level with specific constraints on tone, response style, and artifact handling.
vs others: More detailed than user-facing documentation about actual personality implementation; reveals how personality constraints are encoded in system prompts rather than just describing personality features.
