# Newer AI models: Gemini 3.5 Flash and GPT-5.5

Published: 2026-05-26 | Source: https://geoready.co/news/newer-ai-models

The audit matrix now runs Gemini 3.5 Flash (released May 19) and GPT-5.5 (April 24) instead of their predecessors - so your score reflects what users actually see today.

AI models evolve fast. A brand that was visible in Gemini 2.5 Flash in March can be half-gone in 3.5 Flash by May - and vice versa. We update the audit matrix as soon as a newer flagship model lands at each provider, so your score always reflects what ChatGPT, Gemini and Claude users actually see right now.

## What changed

Two upgrades in this round:

- **Gemini 3.5 Flash** (released May 19, 2026 at Google I/O) replaces Gemini 2.5 Flash as Google's flash-tier model.
- **GPT-5.5** (released April 24, 2026) replaces GPT-5.4 as OpenAI's top-tier model.

Claude Sonnet 4.6, Claude Haiku 4.5, Gemini 2.5 Pro, GPT-5.4 Mini and the Mistral models stay the same - they're still the latest flagships in their respective tiers.

## What it means for you

Historical audits from before today keep their existing scores - they ran on the models that were current then. New audits run on the new matrix.

No action required. Your next scheduled or manual audit will automatically use the new models.
