Engaging Foundation Model Providers: OpenAI, Anthropic, and Google as Direct AI Vendors

Engaging foundation model providers directly — rather than through hyperscaler marketplaces — gives access to the newest capabilities first but requires distinct governance work. The complete guide to direct engagement with OpenAI, Anthropic, and Google DeepMind — covering enterprise tier offerings, contractual terms, data handling, capability access, and the trade-offs versus hyperscaler-mediated access.

Key Takeaways

Direct engagement with foundation model providers (OpenAI, Anthropic, Google DeepMind) offers access to newest capabilities first but requires distinct governance work versus hyperscaler-mediated access.
Enterprise tier offerings provide stronger data handling commitments than consumer or developer-tier API access — confirm enterprise tier and specific terms in contracts.
GPAI provider obligations under EU AI Act Article 53 (from 2 August 2025) apply to foundation model providers — they must publish training data summaries, technical documentation, copyright compliance evidence.
Frontier AI providers have voluntary safety commitments under the Seoul AI Safety Summit framework and Frontier AI Safety Commitments — useful evaluation reference.
AI Safety Institute (CAISI, AISI) pre-deployment evaluations cover the major frontier model providers; safety evaluation reports are increasingly available.
Direct engagement offers earlier access, more customisation, direct technical support — but requires more governance investment than hyperscaler-mediated access.

Engaging foundation model providers directly — rather than through hyperscaler marketplaces — gives enterprise buyers access to the newest capabilities first, more customisation options, and direct technical support relationships. It also requires distinct governance work versus hyperscaler-mediated access. The major direct-engagement options are OpenAI (enterprise tier, API, deployment partnerships), Anthropic (Enterprise tier, Claude API, partnership programs), and Google DeepMind (Gemini Enterprise, API access, direct partnerships). This guide covers the practical engagement framework, the contractual terms that matter, and the trade-offs versus hyperscaler-mediated access.

OpenAI direct engagement

OpenAI's enterprise offerings: ChatGPT Enterprise and ChatGPT Business (workspace-level access with enterprise-tier data handling), the OpenAI API (developer-tier with separate enterprise commitments available), and direct enterprise partnerships (deployment partnerships for very large customers, custom model training, dedicated capacity). Data handling at enterprise tier: customer data is not used to train OpenAI models, SOC 2 Type II, GDPR compliance, HIPAA-eligible options, data residency in specific regions. The API tier requires explicit opt-out from training (default opt-out for API since March 2023, but verify current terms). OpenAI also provides Microsoft-mediated access through Azure OpenAI Service — for many enterprise customers, Azure-mediated access provides better governance posture than direct API engagement. Direct OpenAI engagement is most valuable for customers needing the newest model access (which sometimes appears in OpenAI direct before Azure), custom model training, or deployment partnership relationships.

Anthropic direct engagement

Anthropic's enterprise offerings: Claude.ai Enterprise (workspace with enterprise data handling), Claude API (developer access with enterprise commitments available), and direct partnerships. Data handling at enterprise tier: customer data is not used to train Anthropic models, SOC 2 Type II, GDPR compliance, HIPAA-eligible options. Anthropic also provides hyperscaler-mediated access through Amazon Bedrock (Claude family models available via Bedrock with AWS-mediated commitments) and Google Vertex (Claude available via Vertex). For customers wanting Claude specifically, the direct engagement option provides earliest access to new Claude releases; Bedrock and Vertex access typically follow after a short delay. Anthropic has published its Responsible Scaling Policy and Acceptable Use Policy, and participates in voluntary frontier AI safety commitments — useful governance evaluation reference.

Google DeepMind direct engagement

Google's foundation model engagement: Gemini Enterprise (Google Workspace integrated AI), Vertex AI direct access, AI Studio for developers, and direct partnerships. The Vertex AI offering is the primary enterprise commercial path, while AI Studio targets developers. Data handling at enterprise tier: customer data is not used to train Google models, SOC, ISO 27001, GDPR, HIPAA-eligible. Google's frontier AI development is principally through DeepMind; Gemini is the commercial product family. Direct Google engagement is most often via Vertex AI rather than separate DeepMind contracts.

GPAI provider obligations under EU AI Act

The EU AI Act Article 53 obligations on General Purpose AI providers apply from 2 August 2025. The obligations: technical documentation maintained and provided to authorities on request; documentation for downstream providers (the integrators and deployers building on the GPAI); copyright compliance with EU copyright law including respect for opt-out from text and data mining (TDM); publicly available summary of training data content. For foundation model providers categorised as having systemic risk (currently primarily GPT-family, Gemini, and frontier Claude/Llama), additional obligations apply: model evaluation including adversarial testing, systemic risk assessment, serious incident reporting, adequate cybersecurity protection. The EU GPAI Code of Practice provides voluntary implementation guidance; participation status varies by provider. For enterprise buyers, confirming provider compliance posture is part of governance assessment.

AI Safety Institute evaluations

The major frontier model providers have pre-deployment evaluation agreements with AI Safety Institutes. The US Center for AI Standards and Innovation (CAISI, formerly US AISI) has agreements with OpenAI, Anthropic, Google DeepMind, Microsoft, Meta, xAI. The UK AISI has similar arrangements. The Australian AISI is building equivalent capability. These evaluations cover safety-relevant capabilities (cyber offence, biorisk, autonomous replication, deceptive behaviour). Public summaries are increasingly available. For enterprise buyers, AISI evaluation status is useful governance evidence — providers participating in pre-deployment evaluation provide additional assurance versus providers that do not.

Voluntary frontier AI safety commitments

The Seoul AI Safety Summit (May 2024) and subsequent international processes have produced voluntary frontier AI safety commitments that the major providers participate in. The commitments include: publishing responsible scaling policies (Anthropic's RSP, OpenAI's Preparedness Framework, Google's Frontier Safety Framework, Meta's responsible deployment, others); risk thresholds at which capabilities would not be deployed; external evaluation. The Frontier Model Forum (industry body including Anthropic, Google, Microsoft, OpenAI, Amazon) coordinates safety research and policy engagement. For enterprise buyers, participation in these voluntary commitments is a useful evaluation signal — particularly where AI use cases are sensitive or where regulator scrutiny is high.

Practical engagement framework

Recommended framework for direct foundation model provider engagement: (1) Determine whether direct engagement is needed (newest capability access, custom training, deployment partnership) or whether hyperscaler-mediated access is sufficient. (2) Confirm enterprise tier and specific data handling commitments in contracts. (3) Document provider compliance posture (SOC 2, ISO 27001, ISO 42001 if available, GPAI compliance, AISI evaluation, voluntary safety commitments). (4) Read model cards and capability documentation for each model deployed. (5) Establish model update monitoring — frontier model providers update at fast pace, and updates can change capability profiles materially. (6) Maintain dual-vendor or fallback capability where business continuity is material. (7) For regulated customers, confirm material service provider classification and CPS 230 (or equivalent) obligations.
