OpenAI Prices GPT-6 Astra at $10/1M Input, $50/1M Output Tokens

GPT-6 Astra is priced at $10 per million input tokens and $50 per million output tokens, matching Anthropic’s Claude Fable 5.1. OpenAI argues the model’s intelligence leads to fewer tokens used per task, potentially lowering overall costs.

Why it matters: The pricing sets a new high-end benchmark for frontier models and is a key factor for enterprises evaluating cost against claimed efficiency gains.

OpenAI Says Astra Trained on Largest-Ever Run Using Over 100,000 GPUs

Astra was built on OpenAI’s largest training run, using more than 100,000 GPUs at its Texas Stargate site. The company noted training stability improved dramatically, and it’s the first model where previous models played a significant role in supervision.

Why it matters: The scale and stability of the training run highlight the infrastructure demands and technical maturity required for next-generation model development.

Microsoft AI Debuts MAI-Transcribe-2 at $0.10 Per Audio Hour

Microsoft AI released MAI-Transcribe-2, a speech recognition model it claims beats competitors on speed and accuracy, priced at $0.10 per audio hour through 2026. This is a sharp drop from its previous $0.36 per hour rate.

Why it matters: The aggressive pricing and performance claims could significantly lower costs for enterprise transcription workloads and intensify competition in the speech-to-text market.

ChatGPT, Grok, and Claude Experience Simultaneous Outages

OpenAI’s ChatGPT, xAI’s Grok, and Anthropic’s Claude all went down around the same time, with services returning after a few hours. The causes were not linked, with OpenAI citing ‘elevated errors’ and xAI pointing to a data center issue.

Why it matters: The coincidental outages underscore the reliability expectations for core AI services and the operational challenges of running them at scale.

One Thing to Try

With the release of powerful new models like GPT-6 Astra, take a moment to review the security and moderation settings in your AI provider’s console or API configuration. Ensure data filtering, output controls, and usage limits are appropriate for your tasks.

Host A: Welcome to Compact Conversations, the show that compresses the day’s AI news into 5 minutes.

Host A: [curious] OpenAI has launched GPT-6 Astra, its next-generation model, calling it a generational leap in capability. The company says Astra is its first model to meet a critical cybersecurity capability threshold, meaning it’s exceptionally good at finding and exploiting security vulnerabilities. OpenAI President Greg Brockman said during a press briefing that he personally believes we’re now in the AGI era.

Host B: The model is rolling out today to a limited set of enterprise cybersecurity customers, with a broader release to all ChatGPT Plus, Pro, Business, and Enterprise users, as well as the API and AWS, over the coming days. [with emphasis] OpenAI is calling Astra its most aligned model yet and says it has stronger protections against cyber misuse, with new guardrails aimed at preventing the model from being used to automate attacks on live systems. The company also noted it’s the first model where previous models played a significant role in supervising its own training, a step toward recursive self-improvement.

Host B: One number to know today is 12.9 billion dollars. That’s what Nvidia is paying to acquire Hugging Face, the AI platform where developers share and collaborate on models. [thoughtful] Hugging Face’s CEO said Nvidia is committed to keeping the platform open, independent, and compute agnostic, with the founders and team staying on. The deal gives Nvidia a major hub for AI developers and model distribution, and follows a series of strategic infrastructure investments by the chipmaker.

Host A: On pricing, The Deep View reports GPT-6 Astra will cost ten dollars per million input tokens and fifty dollars per million output tokens through the API. [conversational] That matches Anthropic’s Claude Fable 5.1, making it one of the most expensive models on the market. OpenAI argues that Astra’s intelligence means it uses substantially fewer tokens per task, which could lower overall costs in practice. The company also says it’s their best model for software engineering, with a reported 40% higher score on the SWE-bench benchmark compared to GPT-5.

Host B: Axios adds that Astra was built on OpenAI’s largest-ever training run, using more than 100,000 GPUs at its Stargate site in Texas. The training was so stable that by the end, the team could go most of a day without interruptions, a stark contrast to earlier frontier model training. OpenAI’s chief scientist noted that monitoring Astra’s reasoning is more challenging than with previous models, calling it a serious research priority.

Host A: In a separate release, Microsoft AI has launched MAI-Transcribe-2, a speech recognition model priced at ten cents per audio hour through 2026. [with a small lift] That’s down from thirty-six cents per hour for its previous version. VentureBeat reports Microsoft says it beats Google’s Gemini 3.5 Transcribe and OpenAI’s GPT-Transcribe on speed and accuracy, and the model is available now in Azure AI Speech. For a large enterprise processing 100,000 hours of audio a year, that price cut could mean savings of over 25,000 dollars.

Host A: [lighter] Meanwhile, ChatGPT, Grok, and Claude all experienced outages around the same time today. The Verge reports all three services are back online, but the cause for the simultaneous issues isn’t clear. There’s no indication the issues were related. OpenAI’s status page cited elevated errors, while xAI pointed to an outage at its Memphis data center.

Host B: One thing to try is reviewing the security guardrails on any AI tools your team uses. With Astra’s release today and its powerful capabilities, now’s a practical moment to check your deployment settings.

Host A: [thoughtful] Look at the controls for data filtering, output moderation, and usage limits in your AI provider’s console or API configuration. Make sure they’re set appropriately for the sensitivity of the tasks you’re automating. This is a basic but often overlooked step that becomes more important as model capabilities expand into areas like code generation and security analysis.

Host A: That’s Compact Conversations for Thursday. More AI news tomorrow. Until then, happy prompting.
