When to choose each
GPT-4.1
Best for
- Long-context API trials using text and image inputs
Watch out for
- Not in the pinned LiveBench snapshot; its independent scores here come from Epoch AI's own GPQA Diamond, FrontierMath and SimpleQA Verified runs
Grok 4.7
Best for
- Output-heavy generation under the 200,000-token prompt line
- A cheaper alternative to the frontier tiers where 500k of context is enough
Watch out for
- The long-prompt threshold is 200,000 tokens, the lowest of any model here, and reaching it doubles input and output for the entire request
- xAI's model page does not state a maximum output for Grok 4.7, so it is recorded as unknown rather than inferred
- That page does not explicitly list image input for this model either, so it is catalogued as text-only
