Grok vs ChatGPT vs Gemini vs Claude (Approximate)
A comparison of leading frontier AI assistants. Figures move fast and vendors rarely disclose parameter counts, so the numbers below are public/reported and approximate. xAI's Grok is the youngest of the four yet competes near the frontier.
| Metric | Grok (xAI) | ChatGPT (OpenAI) | Gemini (Google) | Claude (Anthropic) |
|---|---|---|---|---|
| Context window (reported, approx.) | ~2M tokens | ~400K tokens | ~1M tokens | ~200K tokens |
| Parameter count | Not disclosed | Not disclosed | Not disclosed | Not disclosed |
| Founded / first model | xAI 2023; Grok 2023 | 2015; GPT era | Google/DeepMind | 2021 |
| Relative strength | Speed, science reasoning, recency | Breadth, ecosystem | Long context, multimodal | Coding, safety |
Takeaway
Grok went from a 2023 startup model to genuine frontier contention faster than any rival. The other labs lead on specific axes, so no single model wins outright; all parameter figures are undisclosed and benchmarks approximate.
