GPT-6.1 Terra pricing: API price, cost per message and plans
What GPT-6.1 Terra costs, three ways: OpenAI's API price per token, what GPT-6.1 Terra's replies actually cost in our test runs, and how many GPT-6.1 Terra messages each llmwise plan includes. Every limit on GPT-6.1 Terra is on its model page.
API prices checked against OpenRouter's GPT-6.1 Terra page. Updated .
Short answer
GPT-6.1 Terra's API price is $1.00 per million input tokens and $5.00 per million output tokens (OpenAI's list price, October 2026). In our 50 test runs a GPT-6.1 Terra reply cost $0.00069 on average (median $0.00059), from $0.00048 a reply on agents and tool use to $0.0014 on coding. In llmwise you pay per message instead: up to 125 GPT-6.1 Terra messages a month on Plus ($10), 250 on Pro ($20), 800 on Max ($50), 1,800 on Ultra ($100) and 4,000 on Studio ($200).

| Agents and tool use | $0.00048 | $0.48 | 646 / 63 | 5 of 5 |
Across all 50 GPT-6.1 Terra replies: $0.00069 on average, $0.00059 at the median, $0.00038 for the cheapest and $0.0020 for the dearest. The GPT-6.1 Terra replies averaged 667 tokens in and 143 out, against the typical message's 4,000 in and 700 out: each test prompt starts a new chat, while a reply deep in a long chat rereads all of it.
GPT-6.1 Terra on each llmwise plan
In llmwise a GPT-6.1 Terra message is one of a published count, however long the reply runs, and you see what's left before you send.
Free trial: GPT-6.1 Terra is in the 2-day free trial of Plus or Pro. Add a card at checkout; cancel before the trial ends and you pay nothing. One free trial per person.
Plus, $10 a month: up to 125 GPT-6.1 Terra messages a month, which is $0.08 a GPT-6.1 Terra message if every message goes to GPT-6.1 Terra.
Pro, $20 a month: up to 250 GPT-6.1 Terra messages a month, which is $0.08 a GPT-6.1 Terra message if every message goes to GPT-6.1 Terra.
Max, $50 a month: up to 800 GPT-6.1 Terra messages a month, which is $0.06 a GPT-6.1 Terra message if every message goes to GPT-6.1 Terra.
Ultra, $100 a month: up to 1,800 GPT-6.1 Terra messages a month, which is $0.06 a GPT-6.1 Terra message if every message goes to GPT-6.1 Terra.
Studio, $200 a month: up to 4,000 GPT-6.1 Terra messages a month, which is $0.05 a GPT-6.1 Terra message if every message goes to GPT-6.1 Terra.
