JAIS Chat
JAIS Chat is a bilingual Arabic and English conversational assistant launched by Core42, part of the UAE's G42 group. It runs on the Jais family of Arabic large language models developed by Inception with MBZUAI and Cerebras, and is built to handle Arabic dialects and cultural context rather than translated English.
- Genuinely Arabic-first training rather than an English model with Arabic bolted on
- Dialect handling targets the hardest and most practically important gap in Arabic AI
- Cross-lingual transfer from a large English corpus keeps reasoning ability intact
- Open weights allow independent evaluation and deployment inside a jurisdiction
- Smaller than the frontier models, and it shows on hard reasoning, coding and mathematics
- The surrounding product lacks the tools, file handling and integrations of mature assistants
- The site was not reachable during this check, so nothing could be confirmed on it directly
Sim
Open-source workspace to build and deploy AI agents Category: AI Chatbots & Assistants.
- Open-source and self-hostable
- Large integration catalog and multi-model support
- Multiple ways to build agents (canvas, chat, API)
- Visual drag-and-drop agent canvas
- Production agents still need technical know-how
- Credit-based paid tiers can get costly at scale
- Results still need a quick human review for best quality
