GPT-4.1 vs Hy3 preview
Hy3 preview leads GPT-4.1 on the Artificial Analysis Intelligence Index, 25.3 to 12.7, and Hy3 preview costs 13.3x less per output token ($0.60 vs $8.00 per million). Updated October 22, 2026; 31 benchmarks have a result for both.
GPT-4.1 or Hy3 preview: which to pick
Neither model has a coding score yet, so the two cannot be ranked on coding.
Pick GPT-4.1 for a larger context window (1.05M against 262K tokens) and work measured by Terminal-Bench Hard (Artificial Analysis run) or LMArena Text: coding, where it leads.

What each workload costs
Three fixed token mixes at each model's listed price, so per-token rates become a bill.
Chat turn
1K input + 500 output tokens
Hy3 preview costs less
Repository review
50K input + 3K output tokens
Hy3 preview costs less
Agent loop
200K input + 10K output tokens
Hy3 preview costs less
Listed OpenRouter rates, without cache or batch discounts. A workload that does not fit a model's context window would need splitting.

Questions
Is GPT-4.1 better than Hy3 preview for coding?
Neither model has a coding score yet, so the two cannot be ranked on coding. Pick GPT-4.1 for a larger context window (1.05M against 262K tokens) and work measured by Terminal-Bench Hard (Artificial Analysis run) or LMArena Text: coding, where it leads.
Which is cheaper, GPT-4.1 or Hy3 preview?
GPT-4.1 costs $2.00 per million input tokens and $8.00 per million output tokens; Hy3 preview costs $0.18 and $0.60. Cost per solved task is known for GPT-4.1 only.
Which has the bigger context window, GPT-4.1 or Hy3 preview?
GPT-4.1, with 1.05M tokens against 262K.
How many benchmarks is the GPT-4.1 vs Hy3 preview comparison based on?
31 benchmarks have a result for both models as of October 22, 2026. GPT-4.1's coding index rests on 0 independent benchmarks and Hy3 preview's on 1. Where only one model has a result, the page says so instead of naming a winner.
