Ecosystem
Reference hubs for who builds AI and which models matter — companies and foundation models as first-class entities.
- OpenAIOpenAI develops the GPT family of foundation models, ChatGPT, developer APIs, and enterprise AI platforms. It helped popularize large language models through ChatGPT and now powers AI assistants, coding tools, enterprise copilots, retrieval systems, and agent-based applications across industries.
- AnthropicAnthropic builds the Claude family of foundation models for enterprises that prioritize instruction following, long-context reasoning, coding quality, and predictable, safety-conscious behavior. Constitutional AI and careful system design are core to how Claude is trained and positioned.
- Google DeepMindGoogle combines frontier AI research (DeepMind), cloud infrastructure (Vertex AI), custom AI hardware (TPUs), and productivity products (Workspace, Android, Search), making it one of the most vertically integrated AI platforms. Gemini is the model layer; Google Cloud and consumer surfaces are the distribution layer.
- MetaMeta advances open multimodal research and releases the Llama open-weight model family used widely in self-hosted AI stacks. Combined with PyTorch, Llama lets organizations train, fine-tune, and serve models without depending on a proprietary API.
Foundation Models
Canonical pages for major LLMs and multimodal models — linked to tools, benchmarks, and guides.
- GPT-5.6OpenAIOpenAI’s GPT-5.6 family (Sol flagship, Terra balanced, Luna cost-efficient) for complex reasoning, coding, multimodal understanding, and agentic tool use. The gpt-5.6 API alias routes to Sol.
- Claude OpusAnthropicAnthropic’s Claude Opus 5 tier for complex agentic coding, enterprise work, long-context analysis, and careful instruction following. Claude Fable 5 sits above Opus for peak widely released capability.
- Claude SonnetAnthropicAnthropic’s Claude Sonnet 5 tier — best combination of speed and intelligence for most production agents and coding, at lower cost than Opus.
- Claude FableAnthropicAnthropic’s Claude Fable 5 — the most capable widely released Claude for long-horizon agents, deep reasoning, and demanding coding workflows. Mythos 5 is the limited-access peer for Project Glasswing.
