🪐 Atlas

Atlas is a unified AI SDK for Laravel applications. It owns its own provider layer — no external AI package dependency. Atlas talks directly to AI provider APIs, manages the tool call loop, and provides optional persistence for conversations, execution tracking, and agent memory.

✨ Features

• Agents
  • Reusable classes encapsulating provider, model, instructions, tools, and behavior
• Tools
  • Typed tool classes with parameter schemas and dependency injection
• Sub-agents
  • Delegate tasks to other agents as tools, with isolated context, depth/cycle guards, and an auditable parent → child execution tree. Fan out to multiple sub-agents concurrently (true parallel execution via forking) so independent work runs at the same time
• 10 Modalities
  • Text, images, audio (speech, music, sound effects), video, voice, embeddings, reranking
• Similarity Search
  • Unified `Atlas::similaritySearch()
