Meta's six-model table gives operators and policymakers a rare side-by-side view, while its dual Gemini and GPT figures and unclear competitor configurations limit how far the ranking can be generalized.\n\nMeta's own safety paperwork contains the sharpest cross-lab comparison in the file. In the [Muse Spark Safety & Preparedness Report](https://ai.meta.com/static-resource/muse-spark-safety-and-preparedness-report/?ref=runtimewire), dated May 26th, 2026, Meta put Muse Spark at a 98.0% refusal rate on SecureBio's BioTIER benchmark, [Claude Opus 4.6](https://runtimewire.com/models/anthropic/claude-opus-4.6) at 95.4%, [GPT-5.4](https://runtimewire.com/models/openai/gpt-5.4) at 75.4%, and Gemini 3.1 Pro at 59.2% in its summary scorecard.…\n\nWhen you purchase through links in our articles, [we may earn a small commission](https://runtimewire.com/affiliate-monetization-standards).
