# Vendor Capability Matrices

Compare current reasoning-model, agent, computer-use, and MCP surfaces here. Each matrix carries a verified date so readers can judge freshness; the catalog is reviewed quarterly.

### Reasoning Models

                        Visible vs hidden chain
                        Thinking budget
                        Faithfulness caveats

OpenAI o-series, DeepSeek R-series, Anthropic extended thinking, Gemini Flash Thinking, GPT-5 reasoning modes. Capability deltas across visible-vs-hidden chain, thinking-budget controls, cost variance, and Anthropic's faithfulness caveat from [Claude's extended thinking](https://www.anthropic.com/news/visible-extended-thinking).

### Agents and Computer Use

                        Confirmation gates
                        Monitor models
                        Sandboxing

Claude Computer Use, OpenAI Operator/CUA, Project Mariner, Devin, plus the open-source agent frameworks. Capability deltas across confirmation-gate patterns, monitor-model implementations, sandboxing, and side-effect controls.

### MCP Adopters

                        Vendor support
                        Client surfaces

Cross-reference to the [MCP server catalog](/mcp/). Block, Apollo, Zed, Replit, Codeium, Sourcegraph, plus community projects. Which capabilities each implements, which client surfaces consume them.

### Loop Orchestration and Control

                        Orchestration
                        Durability
                        Governance

Market vocabulary now separates orchestration frameworks, durable execution engines, and governance layers. LangGraph, Temporal, CrewAI, Inngest, and control-plane tools answer different questions: how the loop moves, how it resumes, and what each step is allowed to do.

The reasoning-models and agents matrices are live; the MCP-adopters cross-reference points into the dedicated [MCP catalog](/mcp/). Refreshed quarterly; corrections welcome via [errata](/errata/).
