Leak claims xAI trails OpenAI and Anthropic by roughly 6-12 months

X user TokenGremlin claims, based on what he could verify, that xAI is roughly 6-12 months behind OpenAI and Anthropic on frontier models:
- Grok 4.7: around Opus 5 level
- Grok 4.8: between Opus 5 and Fable 5
- Grok 4.9: potentially Astra / Fable 5.1 class
- Grok 5: supposedly meant to surpass all of them
The core issue is timing: by the time these models ship publicly, OpenAI and Anthropic's internal research will likely have moved further ahead. The author reads this as why Musk backs slowing competitors' public releases. Unverified leak / personal assessment.
