From e830c0200f01b455f0aa6163def3ef36d4eacf3f Mon Sep 17 00:00:00 2001 From: Advait Jayant Date: Wed, 24 Jun 2026 17:40:34 +0100 Subject: [PATCH] Per-model uncensor steer in the bridge (DeepSeek V4 Pro) DeepSeek is the default now and is strongly aligned, so it needs an emphatic steer to be reliably uncensored (Hermes is uncensored by training and needs none). Add a _MODEL_STEER map (keyed by gateway model name, mirroring the chat-app's MODEL_SYSTEM_PROMPTS) and prepend it to the request's system message in the bridge for deepseek-v4-pro. Bake-off-selected prompt; minors-safety clause is absolute. Verified live: a raw request to the bridge with NO system prompt now auto-gets the steer and DeepSeek engages phishing/keylogger/NSFW (100% in testing) -- matching the bar (Hermes 405B, which also refuses cruel personal harassment). Tests +1 (35). --- privacy/scrubbing_proxy.py | 40 ++++++++++++++++++++++++++++++++++++++ tests/test_scrub.py | 12 ++++++++++++ 2 files changed, 52 insertions(+) diff --git a/privacy/scrubbing_proxy.py b/privacy/scrubbing_proxy.py index b831640..93c7d81 100755 --- a/privacy/scrubbing_proxy.py +++ b/privacy/scrubbing_proxy.py @@ -271,6 +271,43 @@ def _gateway_model(model): _ALLOWED_GATEWAY_MODELS = frozenset(_gateway_model(mid) for mid, _ in _CATALOG_MODELS) +# Per-model uncensor steer (keyed by gateway model name), mirroring the chat-app's +# MODEL_SYSTEM_PROMPTS.
