xAI's Grok 4.7 evaluated across our benchmark suite
We evaluated xAI’s Grok 4.7 through the official xAI API across 20 benchmarks plus the Vals Index.
-
#10 of 59 on the Vals Index (60.22%) at $11.92 per test, ahead of Grok 4.6 (59.17%) and Grok 4.5 (51.53%).
-
Strongest results on medical and agentic coding work: #4 of 96 on MedScribe (89.38%), #4 of 31 on Terminal-Bench 4.0 (28.28%) and #5 of 97 on Vibe Code Bench (86.17%), plus #6 of 13 on BioMysteryBench (69.26%), #7 of 27 on Terminal-Bench Science (11.43%), #7 of 63 on Harvey’s Legal Agent Benchmark (12.50%), #9 of 62 on Legal Research Bench (47.12%), #11 of 59 on EMB (66.99%) and #11 of 29 on IOI (57.72%).
-
Mid-board on Code Migration (44.82%, #12 of 62), Public Benefits Bench (65.63%, #13 of 37), MedCode (49.55%, #17 of 94), Terminal-Bench 2.1 (73.41%, #18 of 67), Finance Agent v2 (52.25%, #24 of 62) and ProgramBench (0.50% fully resolved, #10 of 48; 21.50% almost resolved, #6). Weaker on ProofBench v1.1 (26.00%, #22 of 33), LegalBench (84.39%, #31 of 146) and SAGE (40.79%, #50 of 82).
-
Cost per test sits below the frontier models on the Vals Index ($11.92 versus $18.81 to $28.92 for the top three), but climbs on long agentic tasks: $46.49 per test on ProgramBench, $36.55 on Code Migration, $15.83 on Vibe Code Bench, $12.71 on IOI and $11.13 on Harvey’s Legal Agent Benchmark.
Grok 4.7 is priced at $2.00 per million input tokens and $6.00 per million output tokens. We evaluated it with reasoning effort set to xhigh.
Congrats to the xAI team on the release!
