GPT-6

Perplexity says it has shifted core engineering workflows, including code changes and production monitoring, onto OpenAI's GPT-6 Astra model. The claim comes from an OpenAI-published case study with no independent benchmark data released.

OpenAI's GPT-6 Astra took first place on ulam.ai's ErdosBench, solving 106 of 226 open math problems and disproving 27 others. Chief scientist Jakub Pachocki says the company deliberately didn't optimize for math research, prioritizing recursive self-improvement work instead.

OpenAI claims its unreleased internal model resolved the Navier–Stokes existence and smoothness problem, one of seven $1 million Millennium Prize Problems. NYU professor Tristan Buckmaster disputes the timeline, alleging OpenAI moved after hearing rumors of his own near-year-long collaboration with Anthropic's Levent Alpöge.

OpenAI claims an internal, unreleased model solved part of the Navier-Stokes Millennium Prize problem using roughly 10,000 concurrent agents over 88 hours. NYU mathematician Tristan Buckmaster has questioned whether the effort drew on his unpublished research with an Anthropic researcher.

A developer named cozyblaze posted on X that a model called 'GPT-6 Astra' completed Portal from start to finish without human intervention in 23 hours 43 minutes. OpenAI has not confirmed the existence of a model by that name, and all details come from a single third-party account.

Vercel released @ai-sdk/openai version 4.0.60, a patch update that adds reasoning configuration support referencing 'GPT-6' in the codebase. OpenAI has not announced a GPT-6 model, making this an early SDK-side scaffolding change rather than confirmation of a new release.

OpenAI has begun rolling out GPT-6 Astra to top-tier ChatGPT plans, the API, Azure, and AWS Bedrock. The model delivers roughly half the usage allowance of GPT-5.6 Sol across comparable plans, with Plus and Business users gaining access in the coming days.

Developer Simon Willison ran his signature 'pelican riding a bicycle' SVG test on newly-accessed GPT-6 Astra across five reasoning levels, comparing results against GPT-5.6 Sol, Terra, and Luna. Even Astra's lowest reasoning setting reportedly beat every Sol output, though Astra costs roughly twice as much per token.

GPT-6 Astra Pro, now listed on OpenRouter, is the existing GPT-6 Astra model configured to run with reasoning.mode set to 'pro' for higher-quality output on complex tasks. It carries a 1M-token context window and tiered pricing from $5/$25 to $20/$100 per million input/output tokens depending on the serving tier.

OpenAI's new GPT-6 Astra model shows major improvements in hallucination rates and jailbreak resistance over predecessor GPT-5.6 Sol, according to OpenAI's system card. However, indirect prompt injection attacks hidden in documents still succeed 8.5% of the time in external testing by Gray Swan, down from 27% but still above rival Claude Opus 5's 4.8% rate.

OpenAI released GPT-6 Astra on Thursday, a model president Greg Brockman says could mark the start of AGI. But the model writes out its reasoning less often than prior versions, and OpenAI's chief scientist says monitoring AI thought processes will keep getting harder.

OpenAI released GPT-6 Astra on September 3, 2026, claiming state-of-the-art computer use and coding performance alongside new alignment techniques. Independent evaluators found real but uneven gains, higher per-task costs, and reduced chain-of-thought monitorability.

OpenAI has begun rolling out GPT-6 Astra, the first model to reach the company's internal 'Critical' cybersecurity threshold. Access is being phased, with companies in OpenAI's Daybreak cybersecurity program getting priority following added safeguards after a prior model containment breach.

A Latent Space report describes GPT-6 Astra, a new OpenAI model the blog says can autonomously handle AI engineering tasks—training models, labeling data, deploying systems—at an estimated cost of under $6 per hour. The claims, including 97.6% on FrontierMath and 99.9% on ARC-AGI-3, come from independent blog testing rather than an official OpenAI announcement.

OpenAI has launched GPT-6 Astra, claiming state-of-the-art results on computer use, coding, and scientific reasoning benchmarks. The model is rolling out to a limited set of organizations first, with general ChatGPT availability expected within days.

OpenAI has begun rolling out GPT-6 Astra, priced at $10/million input and $50/million output tokens to match Claude Fable. The model claims a 99.9% score on ARC-AGI 3 using a custom harness and leads on security and long-context benchmarks, though it trails Fable on general intelligence rankings.

The openai-python SDK v3.8.0 release notes, dated September 3, 2026, list a feature addition for 'gpt-6-astra' — a model name not previously confirmed by OpenAI. No official announcement, pricing, or specifications have been released.

OpenAI has released GPT-6 Astra, its most capable model yet, with benchmark scores the company says surpass GPT-5.6 Sol and Anthropic's Fable 5 models. President Greg Brockman called it a step into the 'AGI era,' though OpenAI acknowledges there's no agreed-upon threshold for that term.

OpenAI is reportedly developing a new model family called Astra, designed to coordinate multiple agents on complex problems over hours or days. The models are already in testing and would be first to go through a planned U.S. government pre-release review, according to The Information.
