Granite Guardian vs Sightengine

Granite Guardian adds safeguards for prompts, responses, and agent workflows around AI models. It detects hallucinations, harmful content, bias, jailbreaking attempts, and retrieval-augmented generation quality issues. RAG checks cover context relevance, response groundedness, and answer relevance. Function calls can be assessed for syntactic and semantic hallucinations, including invalid calls or fabricated information. Granite Guardian 4.1 offers thinking mode with reasoning traces and non-thinking mode with a judgment score; the 4.1 8B model accepts user-defined criteria such as formatting, length, and domain instructions. Models use the Apache 2.0 license for research and commercial use and can run in vLLM or listed providers including watsonx.ai, Ollama, and LM Studio. IBM says they are trained and tested only on English data and should be used strictly in the prescribed scoring mode.

Sightengine provides APIs to assess, filter, and moderate images, videos, and text. Its visual moderation checks categories including nudity, hate, violence, drugs, weapons, and self-harm. It also detects AI-generated images, videos, speech, and music, as well as deepfakes. Additional tools include OCR and QR moderation, image and video search, age estimation, liveness checks, and recapture detection. Image moderation thresholds and rules can be configured for different community policies. Developers can use API examples and SDKs for Curl, Python, PHP, and Node.js. Sightengine says it does not involve human moderators or share customer content with third parties. The Free plan costs nothing and has daily and monthly usage limits; it does not include video processing or live-stream support. Starter costs $29 a month for 10,000 operations, with additional operations at $0.002 each. Sightengine is cloud-deployed and lists API and web platforms.
