OpenAI releases GPT-Live-1 for simultaneous voice conversations

OpenAI released GPT-Live-1 in its API on Sept. 10, so developers can build voice agents without stitching together separate speech-to-text, language-model, and text-to-speech systems. The full-duplex model, meaning it listens and speaks at the same time, can delegate tool use and deeper reasoning to a backend model. Its front-end voice layer costs $0.05 per minute. OpenAI says GPT-Live-1 improved Full Duplex Bench by 30 points over GPT-Realtime-2.1 and ranked first on Tau3 when paired with GPT-6 Astra at medium reasoning.

Perplexity uses GPT-6 Astra to change production systems

On September 14, 2026, Perplexity said it uses GPT-6 Astra to write communications, change real-world systems, and monitor production software. The model handles end-to-end systems under the company’s supervision, extending its work beyond isolated tasks. Perplexity’s cofounder says the company checks in less frequently than it did with earlier models.

OpenAI rewrites core storage platform in Rust

Habitat, the storage platform behind ChatGPT, the API, Codex, and OpenAI’s internal services, now handles more than 70 million requests per second for products used by more than 1 billion people weekly, OpenAI said yesterday. In the second quarter, two engineers used Codex and GPT-5.5 to rewrite the service from Python to Rust. The Rust service now carries 95% of production traffic. By OpenAI’s measurements, it is six times more CPU-efficient and 15 times more memory-efficient than the Python version.

SpaceXAI installs 720 battery containers at Memphis AI campus

Canary Media counted 720 Tesla Megapack containers at SpaceXAI’s Colossus 2 campus in July satellite images, according to its yesterday account. That count would equal about 2.8GWh and 720MW to 1,400MW, depending on the Megapack version. A SpaceXAI executive cited 3.3GWh in August, while Memphis Light, Gas and Water’s CEO described 2GW of behind-the-meter batteries, meaning storage connected on the campus side of the utility meter. The utility says the campus had to be able to come off the grid for four hours as a condition of its interconnection; storage at this scale can buffer peak demand and support curtailment when the grid is stressed.

Cognition adds GPT-6 Astra to Devin testing workflows

Cognition said yesterday that it was using GPT-6 Astra across its products, including Devin, its cloud coding agent. For an iPhone game, Devin tests the app and returns a simulator recording with a report separating passed checks from those it did not test. Engineers receive evidence from the running app to review alongside the code change. Cognition also says a developer can send Devin a bug screenshot and receive a fix with an image showing the result.

OpenAI expands GPT-Rosalind access worldwide

Yesterday, OpenAI opened GPT-Rosalind globally to eligible organizations through a trusted-access program, ending its research preview. Qualified researchers can connect literature evidence to biological data and run repeatable computer-based analysis workflows, with artifacts preserved for expert review. The update adds Codex plugins and biological-data viewers. OpenAI reports higher scores than GPT-5.5 on medicinal-chemistry, genomics, and wet-lab-protocol evaluations.

Sakana releases four Fugu offerings through one API

Sakana AI made Fugu, Fugu Ultra, Fugu Max, and Fugu Cyber available through one OpenAI-compatible API today. Developers can call one endpoint for coding, reasoning, research, or security work while the service selects and coordinates specialized models. Fugu Max costs $2 per million input tokens and $6 per million output tokens, while Fugu Cyber is intended for vulnerability research, threat investigation, and security analysis. Organizations can exclude particular providers or models from the pool for privacy or compliance reasons.

Positive - Sakana made a specialized cyber model available for vulnerability research and threat investigation, expanding defenders’ analytical tools.

New Mexico court fines lawyer over ChatGPT-invented witnesses

The New Mexico Supreme Court held defense lawyer Stephen Aarons in direct contempt and fined him $5,000 on Sept. 9 after he filed an AI-generated murder-appeal brief containing fabricated witness testimony and inaccurate legal claims. The unverified filing delayed a criminal appeal and forced the court to restart part of the process. The justices struck the briefs, ordered new counsel for the defendant, and referred Aarons to a disciplinary board.

Negative - A lawyer filed fabricated AI-generated testimony and legal claims in a murder appeal before court review caught the misuse.
Positive - The court struck the tainted briefs, appointed new counsel and imposed sanctions, preventing the fabrications from shaping the appeal.

OpenAI withdraws Caltech math-event sponsorship after criticism

Twenty-five Fields Medal recipients signed an open letter on Sept. 10, warning that rushed AI proof announcements can obscure methods, attribution, and scholarly review. A proof may take years to validate and teach, making clear provenance important for researchers assessing the work. After Caltech researchers criticized its sponsorship of an undergraduate mathematics hackathon, OpenAI withdrew from the event.
