Low, medium, and high presets use GPT-6

Perplexity's Agent API low, medium, and high presets now use GPT-6 model variants instead of GPT-5.6. The low and medium presets switched to openai/gpt-6-luna, while the high preset switched to openai/gpt-6-sol. Prompts, reasoning effort, tools, token budgets, and step limits remain unchanged.

GPT-6 Astra, Sol, and Luna: For production agents in Microsoft Foundry

Today, we are expanding our GPT-6 series by welcoming GPT-6 Sol and GPT-6 Luna to our generally available lineup in Microsoft Foundry . Building on the exceptional customer momentum of GPT-5.6 Sol and GPT-6 Astra , this launch continues our work to deliver transformative capabilities in Microsoft Foundry that produce less noise and are more capable at completing full tasks with agents . Explore GPT models in Foundry today Astra brings advanced reasoning , software engineering and computer use to demanding work that requires both judgment and action. Azure customers report a step-change in capabilities, and strong cost-to-performance with the model using fewer, higher-value tokens to drive agents. Completing the lineup, GPT-6 Sol is excellent for general-purpose use, while Luna brings efficient intelligence to high-volume data and preparatory work. Put the right intelligence behind every agent The right model for a job should be determined through evaluations: an agent handling a complex business decision and one routing routine requests have different needs. Microsoft recommends customers start with GPT-6 Astra for demanding work. …

Bring more intelligence to everyday work with GPT-6 Sol and GPT-6 Luna on Amazon Bedrock

GPT-6 Sol and GPT-6 Luna are now generally available on Amazon Bedrock, giving you more options to match intelligence and efficiency to each workload. The value of AI at scale depends on two dimensions: what a model can do and how often you can put it to use. Greater intelligence expands the complexity a model can handle, from subtle coding problems to multistep processes across tools. Efficiency determines how broadly that intelligence can support everyday activity and repeatable tasks, where every additional token, retry, and second of latency multiplies across requests. GPT-6 Astra established the upper end of the GPT-6 family for the most ambitious projects, where achieving the highest-quality result matters more than cost. Organizations also need advanced intelligence for the recurring tasks that keep products and operations moving. GPT-6 Sol brings strong reasoning and coding capabilities to complex tasks performed throughout the week, with economics suited to regular use. GPT-6 Luna makes focused, repeatable tasks practical at high volume, where small differences in latency and cost multiply across requests. …

Introducing GPT-6 Sol and Luna

OpenAI announced GPT-6 Sol and GPT-6 Luna, two new models in the GPT-6 family that offer improved cost efficiency while bringing advances from GPT-6 Astra to professional work, factuality, coding, and alignment. API prices for Sol and Luna are reduced by 50% compared to their GPT-5.6 promotional pricing. The models outperform similarly priced competitors on benchmarks such as AutomationBench, Agents' Last Exam, FrontierCode, and DeepSWE at lower cost per task.

Introducing GPT-6.1 Sol

OpenAI released GPT-6.1 Sol, an upgrade to GPT-6 Sol that nearly matches GPT-6 Astra's performance on agentic coding, computer use, and professional work at one-fifth of Astra's standard token prices. Cached input costs $0.10 per million tokens, 95% less than standard input pricing and 50% less than GPT-6 Sol's cached input pricing. The model shows improvements over GPT-6 Sol in coding benchmarks (DeepSWE v1.1), professional document tasks (GDP.pdf), computer use (OSWorld 2.0), scientific research (Terminal-Bench Science 0.1), and factuality, with lower failure rates in alignment evaluations.
