Grok Build 0.1 vs Inkling
Grok Build 0.1 leads Inkling on the Artificial Analysis Intelligence Index, 27.2 to 25.0, and Grok Build 0.1 costs 2.0x less per output token ($2.00 vs $4.05 per million). Updated October 22, 2026; 3 benchmarks have a result for both.
Grok Build 0.1 or Inkling: which to pick
Only Inkling has a coding score, 31.5 on the Vibe Coding Index; Grok Build 0.1 has none, so the two cannot be ranked on coding.
Pick Grok Build 0.1 for output tokens 2.0x cheaper ($2.00 vs $4.05 per million) and work measured by AA Intelligence Index, where it leads.

Questions
Is Grok Build 0.1 better than Inkling for coding?
Only Inkling has a coding score, 31.5 on the Vibe Coding Index; Grok Build 0.1 has none, so the two cannot be ranked on coding. Pick Grok Build 0.1 for output tokens 2.0x cheaper ($2.00 vs $4.05 per million) and work measured by AA Intelligence Index, where it leads.
Which is cheaper, Grok Build 0.1 or Inkling?
Grok Build 0.1 costs $1.00 per million input tokens and $2.00 per million output tokens; Inkling costs $1.00 and $4.05. Cost per solved task is known for Inkling only.
Which has the bigger context window, Grok Build 0.1 or Inkling?
Inkling, with 524K tokens against 256K.
How many benchmarks is the Grok Build 0.1 vs Inkling comparison based on?
3 benchmarks have a result for both models as of October 22, 2026. Grok Build 0.1's coding index rests on 1 independent benchmark and Inkling's on 6. Where only one model has a result, the page says so instead of naming a winner.
