Mission and Philosophy

OpenAI: Move Fast, Build AGI

OpenAI was founded with the mission to ensure artificial general intelligence (AGI) benefits all of humanity. In practice, OpenAI has pursued an aggressive product strategy, launching ChatGPT, DALL-E, GPT-4, voice mode, and numerous features at a pace that has defined the industry’s tempo. Their approach prioritizes getting advanced AI into users’ hands quickly while iterating on safety.

Anthropic: Safety-First AI

Anthropic was founded by former OpenAI researchers (including Dario and Daniela Amodei) who wanted to focus more heavily on AI safety research. Their Constitutional AI approach trains models to be helpful, harmless, and honest using explicit principles. Anthropic publishes extensive safety research and has been more cautious about capability releases, though they’ve accelerated significantly in 2025-2026.

Google DeepMind: Research-Driven Scale

Google DeepMind (formed by merging Google Brain and DeepMind in 2023) brings decades of AI research to the table. Google’s advantage is scale: Gemini models are integrated into Search, Gmail, Docs, Android, and Google Cloud, reaching billions of users. Their approach combines cutting-edge research (AlphaFold, AlphaCode) with massive distribution. For a closer look at the consumer products, see our Claude vs ChatGPT comparison.

Model Lineups Compared

Tier	OpenAI	Anthropic	Google
Flagship	GPT-4o	Claude Opus 4.6	Gemini Ultra
Reasoning	o3, o4-mini	Extended Thinking	Gemini with Deep Think
Mid-tier	GPT-4o mini	Claude Sonnet 4.6	Gemini Pro
Fast/Cheap	GPT-4o mini	Claude Haiku 4.5	Gemini Flash
Image Gen	DALL-E 3 / GPT-4o	None	Imagen 3
Video Gen	Sora	None	Veo 2
Context Window	128K tokens	200K tokens	1M+ tokens

Context Window: Google Leads

Google’s Gemini models support over 1 million tokens of context — roughly 10x more than OpenAI and 5x more than Claude. This makes Gemini the clear choice for processing extremely long documents, entire codebases, or video transcripts. However, in practice, performance tends to degrade at the extremes of context length for all providers. Claude’s 200K tokens represents the sweet spot for most professional use cases.

Multimodal Capabilities

OpenAI and Google lead in multimodal features. Both offer text, image, audio, and video understanding plus generation. Anthropic focuses on text and image analysis (no generation), betting that doing fewer things extremely well beats trying to do everything. For users who need image and video generation alongside text, OpenAI or Google are stronger choices.

API Pricing Comparison

Model	Input (per 1M tokens)	Output (per 1M tokens)
GPT-4o	$2.50	$10.00
Claude Sonnet 4.6	$3.00	$15.00
Gemini Pro	$1.25	$5.00
GPT-4o mini	$0.15	$0.60
Claude Haiku 4.5	$0.80	$4.00
Gemini Flash	$0.075	$0.30
Claude Opus 4.6	$15.00	$75.00
o3	$10.00	$40.00

Cheapest option: Google’s Gemini Flash at $0.075 per million input tokens is the most affordable for high-volume, simple tasks. Best value at mid-tier: GPT-4o and Gemini Pro offer strong performance at competitive prices. Premium tier: Claude Opus is the most expensive but often delivers the highest quality for complex reasoning tasks.

Developer Experience

OpenAI API

OpenAI’s API is the most mature and widely adopted. Extensive documentation, large community, thousands of tutorials, and broad third-party library support make it the easiest to get started with. Features include function calling, structured outputs, fine-tuning, batch API, and the Assistants API for building conversational agents.

Anthropic API

Anthropic’s API emphasizes simplicity and developer ergonomics. Key differentiators include the Model Context Protocol (MCP) for standardized tool integration, prompt caching for cost savings on repeated context, and a tool use system that makes building agents straightforward. The Claude SDK is well-documented and the API surface is intentionally smaller and easier to learn.

Google AI (Vertex AI / AI Studio)

Google offers two entry points: Google AI Studio for quick experimentation (free tier, web-based) and Vertex AI for production deployments with enterprise features. Google’s advantage is integration with the broader Google Cloud ecosystem — BigQuery, Cloud Functions, Kubernetes, and more. The Gemini API supports grounding with Google Search, making it easy to build applications that reference real-time web data.

Safety and Alignment Approaches

Each company takes a distinct approach to AI safety:

OpenAI

• RLHF (Reinforcement Learning from Human Feedback) as the primary alignment technique
• Safety classifiers and content filters layered on top of base models
• Preparedness Framework for evaluating model risks before deployment
• Bug bounty program for safety research
• Has become more permissive over time in response to competitive pressure

Anthropic

• Constitutional AI (CAI) — models trained against explicit principles
• Extensive red-teaming and adversarial testing
• Published Responsible Scaling Policy (RSP) with defined capability thresholds
• Most conservative content policies among the three
• Focus on interpretability research to understand what models are “thinking”

Google DeepMind

• Responsible AI principles published since 2018
• AI safety research through DeepMind’s alignment team
• Enterprise-grade compliance (SOC 2, HIPAA, FedRAMP, ISO 27001)
• Gemini safety filters integrated across Google products
• Largest team dedicated to AI ethics and policy

Enterprise Features
