OpenAI’s New AI Model Rivals GPT-6 Astra at One-Tenth the Cost

OpenAI has introduced GPT-6.1 Terra, a new AI model designed to complete everyday work tasks faster, create fewer mistakes, and cost significantly less than its predecessor.

Key points

• GPT-6.1 Terra's standard API rates are additionally 50% lower than those of GPT-5.6 Terra and GPT-6.1 Sol.
• OpenAI Launches New AI Tool That Makes Decisions Up to 10 Times Faster.
• GPT-6.1 Terra is available to ChatGPT Plus, Pro, Enterprise, and Edu subscribers through ChatGPT Work and Codex.
• OpenAI claims GPT-6.1 Terra completes tasks more than three times faster than GPT-6 Astra and GPT-6.1 Sol.
• At maximum effort, it fell by 18 percentage points to 4.3%, approaching the accuracy of GPT-6 Astra and GPT-6.1 Sol in the same evaluation.

In practice, the firm states the model brings improvements in writing, coding, visual understanding, and computer-based tasks. It can support users create documents, understand technical drawings, fill out forms, and edit videos.

GPT-6.1 Terra's standard API rates are additionally 50% lower than those of GPT-5.6 Terra and GPT-6.1 Sol. Faster Performance and Better Computer Employ.

OpenAI notes GPT-6.1 Terra can perform complicated tasks involving multiple applications, including converting architectural drawings into 3D models and examining videos frame by frame.

In the Agents' Last Exam benchmark, the model scored 15 percentage points higher than GPT-5.6 Terra at medium reasoning effort while costing approximately one-third as much per task.

It additionally matched GPT-6 Astra's performance at roughly one-tenth its rate per token.

For context, the model additionally demonstrated improvements in visual understanding, almost matching OpenAI's more powerful models in the MMMU-Pro benchmark while operating at a lower cost. OpenAI and Anthropic Slashed AI Model Rates by Up to 80%.

OpenAI notes it has significantly reduced the number of factual mistakes produced by GPT-6.1 Terra.

In the company's internal tests involving tough questions, the model's error rate fell substantially compared with GPT-5.6 Terra. Reasoning Level GPT-5.6 Terra GPT-6.1 Terra. Low 53.6% 16.7%. Maximum 22.3% 4.3%.

At low reasoning effort, the factual error rate dropped by almost 37 percentage points.

These results come from OpenAI's internal testing and do not mean the model will achieve the same accuracy in every situation. GPT-6.1 Terra additionally brings significant improvements in software development.

In Terminal-Bench 4.0, a benchmark measuring how well AI agents complete programming tasks, the model solved 50.3% of challenges at maximum reasoning effort. That is more than double the performance of GPT-5.6 Terra. Model Coding Benchmark Score. GPT-5.6 Terra 21.5%. GPT-6.1 Terra 50.3%.

Notably, the model additionally performed strongly in scientific coding tests, outperforming GPT-6.1 Sol in one benchmark while costing less.

Nevertheless, OpenAI states GPT-6.1 Sol and GPT-6 Astra remain better choices for the most complicated programming tasks. Improved Safety and Reliability.

OpenAI notes GPT-6.1 Terra is better at after instructions, recognizing limitations, and explaining when it cannot complete a task.

For context, the firm additionally reports stronger resistance to malicious instructions designed to manipulate AI systems.

Notably, the model meets OpenAI's Critical cybersecurity capability threshold under its Preparedness Framework and includes safety protections developed for GPT-6 Astra.

OpenAI notes subscribers can complete more tasks within their existing usage allowances compared with GPT-5.6 Terra, GPT-6.1 Sol, and GPT-6 Astra.

Developers can access the model through the OpenAI API using the name gpt-6.1-terra. The API pricing is as follows. Usage Type Cost per 1 Million Tokens. Cached Input $0.05.

OpenAI notes the lower pricing will produce the model more practical for businesses that need to automate sizeable numbers of repetitive tasks, such as reading invoices, entering information into accounting software, and processing documents. Stay Connected with ProPakistani.
