• Embeddings - Text embeddings for semantic search and similarity
• Assistants API - Purpose-built AI assistants with persistent threads

Research and Safety

OpenAI conducts cutting-edge AI research with a focus on:

• Alignment and safety
• Reinforcement learning from human feedback (RLHF)
• Constitutional AI
• Model interpretability
• AI governance

Acquisition Strategy (2025-2026)

OpenAI has pursued an aggressive acquisition strategy focused on infrastructure, developer tools, and vertical integration. No single acquisition directly enabled OpenAI Frontier, but a coordinated pattern of acquisitions supports the platform:

Infrastructure & Developer Tools

Acquisitions:

• Statsig ($1.1B, September 2025) - Product testing and experimentation framework; CEO Vijaye Raji appointed CTO of Applications
• Neptune (December 2025) - Model training dashboards, visualization, and debugging tools
• io ($6.5B, May 2025) - Hardware company co-founded by Jony Ive for proprietary AI hardware
• Sky (October 2025) - macOS natural language interface for desktop applications
• Torch ($60M, January 2026) - Healthcare AI startup to strengthen medical data capabilities
• Roi (October 2025) - Personal finance app (financial services expansion)

Computing Infrastructure Partnerships:

• Oracle - $300 billion contract for computing power (5 years)
• CoreWeave - $11.9 billion over 5 years for AI infrastructure access
• AMD - $6+ gigawatts of chips with option to purchase ~10% of company
• NVIDIA - $100B investment memorandum (as of January 2026, “rethinking partnership”)
• Disney - $1B investment + licensing deal for Sora (video generation with Disney/Marvel/Star Wars content)
• Amazon - Advanced discussions for up to $50B investment (AI partnership for Alexa integration)

Strategic Pattern Revealed

Rather than acquiring an existing agent orchestration platform, OpenAI built OpenAI Frontier internally while strategically acquiring:

1. Developer tools (Statsig, Neptune) for evaluation, testing, observability
2. Interface layers (Sky) for user experience and multi-application control
3. Hardware (io) for proprietary deployment infrastructure
4. Vertical-specific expertise (Torch for healthcare, Roi for finance)
5. Massive computing capacity (Oracle, CoreWeave, AMD) to power frontier models and agent operations

This vertical integration strategy positions OpenAI as a comprehensive AI platform company—not just a model provider, but capable of delivering deployed agents and applications end-to-end across enterprise and consumer markets.

Notable Events

2026

• Frontier launch (February 5) - Enterprise platform for deploying AI agents with persistent identity, scoped permissions, and governance
• Codex App for macOS (February 2) - Desktop application for multi-agent coordination and code supervision
