Last updated on February 16, 2026

MX4 Atlas supports multiple model families for chat, retrieval, and domain‑specific workflows. Availability and capacity depend on your deployment and licensing. Use Atlas Studio to view the live catalog in your environment.

Catalog Overview

Family	Use Cases	Notes
mx4-atlas-core	General chat, reasoning, tool orchestration	Primary routing target for mixed workloads
mx4-embed-v1	Semantic search, retrieval, clustering	Arabic‑aware embeddings for RAG
External Providers	Specialized or proprietary models	Optional connectors using your credentials

Model IDs can differ by deployment. Use Atlas Studio for the authoritative list.

Capabilities

Chat & Reasoning

Multi‑turn dialogue, instruction following, and agent‑style orchestration.

Embeddings

Arabic‑aware vector representations for search, clustering, and reranking.

Fine‑Tuning

Customize base models with your domain data and preferred tone.

Model Selection Guide

Choose Atlas Core for

Mixed workloads that need routing or tool usage
Arabic‑first responses with strong general reasoning
Enterprise workflows with strict sovereignty requirements

Choose Embeddings when

You need semantic search across Arabic corpora
You are building RAG pipelines or vector search
You need deterministic, cacheable representations

Routing Profiles

Use routing profiles to balance quality, cost, and latency. Profiles are configured in Atlas Studio and can be adjusted per request.
