# Official LLM brand assets — download URLs

The LLM SVGs in `llm-logos.svg` are simplified in-house renditions for use at 20-28 px in footer / inline contexts. For higher-fidelity placements (press kit, blog images, partner pages, slide decks) Design must download the official brand SVGs from each vendor.

| Brand | Official brand page | Notes |
|---|---|---|
| Anthropic / Claude | https://www.anthropic.com/brand | Wordmark, sunburst mark, color tokens, usage rules |
| OpenAI / ChatGPT | https://openai.com/brand | Spark / hexagonal flower mark + wordmark |
| Google / Gemini | https://about.google/brand-resource-center/ — Gemini section in `https://ai.google.dev/static/site-assets/images/brand/` | Star/sparkle mark, gradient |
| Perplexity | https://www.perplexity.ai/brand | Wordmark + logomark |
| xAI / Grok | https://x.ai/brand (or via the X press kit) | Wordmark + glyph |
| DeepSeek | https://www.deepseek.com (look for `/press` or `/brand`) | Whale-form logomark |

## Compliance notes

- **Never** color-shift another brand's logo. Use the supplied palette only.
- **Never** apply the ENTIA verified seal directly to a third-party logo — implies endorsement.
- **Never** show an LLM logo larger than the ENTIA logo on an ENTIA-owned page (unless the page is explicitly co-branded and reviewed by Legal).
- LLM logos in our footer carry an implicit "verified-against" relationship — keep them at the documented 20-28 px and grouped, not isolated.

## What we have already (in repo)

| File | Where | Quality |
|---|---|---|
| `llm-logos.svg` | this folder | Simplified, optimized for 20-28 px |
| `llm-logos.css` | this folder | 2 utility sizes |
| Inline SVG in `entia-footer.js` | `04_HEADER_FOOTER/` | Same simplified marks, embedded in footer |

If Design produces a higher-fidelity replacement set following the official brand pages, drop them in this folder as `llm-logos-hd.svg` and update `llm-logos.css` with new size classes. Keep the originals — older landings still reference them.
