CleanSpeak vs Granite Guardian

CleanSpeak is a configurable moderation toolset for services that need to filter or review user content. It filters text, images, and video, and can moderate audio but does not filter it. Moderation queues let teams review and escalate material, while custom rules can automate actions by content source, rate users, and trigger actions from those ratings. Editable blocklists detect negative terms and phrases, including altered forms intended to bypass filters. The product includes 22+ base language lists that customers can change or supplement. Tunable text, image, and video models integrate Google Perspective and SightEngine; reports cover moderator activity, content searches, and term or model frequencies. CleanSpeak is available as managed cloud service or as server software installed and maintained by customers. Its synchronous REST APIs return JSON for real-time integration across content filtering, moderation, and user management. The company says one server can filter 10,000 or more messages per second. It serves use cases in apps and gaming, retail and hospitality, and enterprise settings. The advertised trial lasts 30 days and requires no credit card; pricing is available on request.

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.
