OpenAI officially released its GPT-6.1 Terra model on October 26, offering developers half the per-token price of its predecessor despite trailing competitor Anthropic on top benchmark metrics. The pricing strategy debuted on the exact day Anthropic publicly filed its S-1 statement for a Nasdaq listing under ticker ANT.
Token Pricing Drops as Benchmark Scores Moderate
The new GPT-6.1 Terra costs $1 per million input tokens and $5 per million output tokens. According to independent testing firm Artificial Analysis, this represents a steep drop from the $2 input and $12 output rates of GPT-5.6 Terra. On the Artificial Analysis Intelligence Index at maximum effort, GPT-6.1 Terra scored 48 points, up from 42 points recorded by GPT-5.6 Terra.
The testing firm placed GPT-6.1 Terra's cost per task at $0.40, down from $1.40 for its predecessor. The model also guesses on 38% of questions it cannot answer, down from 88%. However, Anthropic models continue to hold the top spots on the index, led by Claude Opus 5.5 at 58 points and Claude Sonnet 5.5 at 56 points. Google's Gemini 4 Argon and OpenAI's GPT-6 Astra both scored 53 points.
Strategic Positioning and Market Valuation
OpenAI has pitched GPT-6.1 Terra as a high-volume tool, claiming it costs about 9 times less per task than Claude Opus 5.5 on its own Agents' Last Exam. For complex developer workloads, OpenAI noted that "For the most complex coding tasks, GPT-6.1 Sol and GPT-6 Astra remain the better choice." Because Terra's cost per task is about 70% below GPT-5.6 Terra at maximum effort, OpenAI would need to sell roughly 3.5 times as many tasks to maintain flat revenue from that workload.
The pricing pivot coincides with Anthropic disclosing $16.29 billion in revenue for the first half of 2026 in its public listing documents, as highlighted in its recent S-1 prospectus filing. Meanwhile, OpenAI Chief Executive Sam Altman has ruled out a public listing this year, with the Financial Times reporting that OpenAI lowered its private round valuation target to $1.25 trillion.
Key Takeaways
- GPT-6.1 Terra is priced at $1 per million input tokens and $5 per million output tokens.
- Artificial Analysis scored GPT-6.1 Terra at 48 points, behind Claude Opus 5.5 (58 points) and Claude Sonnet 5.5 (56 points).
- Anthropic filed to list under ANT on Nasdaq following $16.29 billion in H1 2026 revenue.
- OpenAI lowered its private funding round valuation target to $1.25 trillion.
Why It Matters
OpenAI's aggressive price reduction for GPT-6.1 Terra signals a strategic pivot toward commoditizing high-volume AI inference tasks like document processing, trading raw benchmark dominance for enterprise adoption volume. By undercutting Anthropic on cost per task just as Anthropic prepares for a high-profile IPO, OpenAI is attempting to lock in developer workflows before public market scrutiny sharpens around AI unit economics. Investors will closely watch whether volume growth can offset lower per-task margins across both private and public AI labs.
