Pricing

  • Official API list price: $1.00 input and $5.00 output per 1M tokens (USD).
  • At a typical 3:1 input-to-output ratio, the blended cost is about $2.00 per 1M tokens.
  • Among 83 models with an output price, it is the #44 cheapest.
  • The cheapest OpenRouter route charges $1.00 input / $5.00 output.

Sources & methodology

GPT-6.1 Terra is not on the arena.ai Agents leaderboard, so it has no rank on our default leaderboard; the other data below is for reference.

  • arena.ai Agents — agent Net Improvement, 95% interval, sessions and rank (via the public Hugging Face dataset, CC BY 4.0).
  • LMArena — Arena score (Text leaderboard with style control, the same view arena.ai shows by default), 95% confidence interval, votes and rank.
  • Artificial Analysis — Intelligence / Coding Index, output speed and latency (medians).
  • OpenRouter — Route prices, context length and listing date.

Arena scores use the Bradley-Terry model (not Elo); ± is the half-width of the 95% confidence interval. Latency figures are Artificial Analysis medians; for reasoning models, time to first token and to first answer include the thinking phase. Data syncs daily at 14:20 (UTC+8).

Limits: Arena scores come from anonymous users voting on chats, so they reflect conversational preference rather than agent or coding benchmarks; with few votes the interval is wide and ranks move. Prices and speeds change as providers update them.

FAQ

What rank is GPT-6.1 Terra right now?

GPT-6.1 Terra has not been scored by LMArena yet, so it is not ranked here.

What does GPT-6.1 Terra cost via API?

Input $1.00 / output $5.00 per 1M tokens (official API list price; the OpenRouter quote when no official price is available). At a typical 3:1 input-to-output ratio, the blended cost is about $2.00 per 1M tokens.

How fast is GPT-6.1 Terra?

Artificial Analysis measures about 92 output tokens per second, 204 s to the first token and 204 s to the first answer token; it is a reasoning model, so latency includes thinking time.

Is GPT-6.1 Terra open source? Can it be self-hosted?

GPT-6.1 Terra is a closed model, available only via official APIs or hosted services.

What is the context length of GPT-6.1 Terra?

1.05M (1,050,000 tokens, as listed on OpenRouter).

Where does the GPT-6.1 Terra data come from and how often is it updated?

Agent success rates come from the arena.ai Agents leaderboard (CC BY 4.0), Text scores from LMArena, intelligence and speed from Artificial Analysis, and prices and context from official list prices and OpenRouter. 17NAS syncs daily at 06:20 UTC; this page was last updated Oct 27, 2026.
