Mistral is excellent for EU moderation.
Add 9 more providers for the same effort.
Mistral's moderation API handles European languages beautifully. But why limit yourself to one provider? OpenModeration uses Mistral plus OpenAI, Azure, HuggingFace, and 7 others through the same API call — with automated rules, human review, and DSA-compliant audit trails.
Why go beyond Mistral alone
Mistral is one of the best EU-focused moderation APIs. But moderation is about the workflow — not just the API.
Mistral is great for EU languages, less so for English
Mistral's moderation API excels at French, German, Spanish, and Italian content. But for English toxicity detection, OpenAI's omni-moderation model is often more accurate. OpenModeration routes English to OpenAI, European languages to Mistral — automatically.
7 categories vs configurable categories
Mistral covers 7 fixed categories. What if your community needs to detect misinformation, grooming, or custom policy violations? OpenModeration adds LLM-based moderation with fully configurable categories — define them in plain language and let GPT-4o or Claude classify.
An API needs an operational layer
Mistral gives you scores. Your team still needs: a review dashboard, an action engine (hide/delete/flag), role-based access, audit trails for DSA, and cost analytics. OpenModeration ships all of this — Mistral becomes one of 10 backend engines.
No pre-filter means paying for obvious spam
Every call to Mistral's moderation endpoint costs money. With OpenModeration's pre-filter, obvious spam, forbidden words, and regex patterns are blocked before any provider sees them — saving 10-30% on API costs across Mistral and all your providers.
Use Mistral through OpenModeration. Get the full platform.
You can keep using Mistral as your primary provider. OpenModeration wraps it with pre-filtering, double thresholds, automated actions, and a complete audit trail — all through the same API call.
Route by language: Mistral for FR/DE/ES/IT, OpenAI for EN, LLMs for custom categories.
Bring your own Mistral key (BYOK) and add other providers for redundancy.
DevX elite — both Mistral and OpenModeration are built by European teams, for developers.
