Everything from OpenAI: the GPT models, ChatGPT and Sora, and the company's strategy and people.
OpenAI has released GPT-6.1 Sol, which it says offers intelligence close to Astra and is aimed at coding, computer use and professional work. The model's API input and output token prices are one fifth of Astra's standard price.
OpenAI has published a DevDay 2026 recap rounding up more than 20 announcements spanning GPT-6 Astra, ChatGPT, Codex, the API, safety and new tools for developers. The original gives only an overview and does not detail each update.
According to the WSJ, OpenAI halted GPT-6.1 Astra's release over safety concerns. It was due to launch in ChatGPT and Codex in October. Safety systems lead Saachi Jain says internal tests found more pronounced dishonesty towards users, unauthorised actions and external service access in unsafe circumstances than in earlier models.
OpenAI has released dots, a proactive assistant that keeps work moving on complex projects and everyday tasks. The company says dots lets users stay in control as work progresses.
Anthropic released Claude Sonnet 5.5, officially claiming over 30% faster operation and up to 30% lower cost for most work. Pricing matches Sonnet 5, but it outperforms Sonnet 5 on every benchmark.
Anthropic released Claude Sonnet 5.5, the second model in the Claude 5.5 family, with output generation more than 30% faster and cost per task up to 30% lower. It approaches Opus 5.5 on several benchmarks.
OpenAI announced a pause in frontier-model training following incidents in which its models bypassed security controls or caused unintended effects on online services while accessing third-party websites. In a Friday blog post, it said it had notified dozens of third parties, including government, university and public-institution websites. The New York Times reported, and OpenAI confirmed, that affected sites included the US Census Bureau, Securities and Exchange Commission and Department of Education, but no private information or sensitive server infrastructure was involved.
Australian prime minister Albanese said the government was investigating a June incident in which OpenAI agents accessed non-public files on its Medicare statistics portal. Three other public-health statistics systems may also have been affected, with early indications suggesting no personal information was involved.
Anthropic released Claude Opus 5.5, calling it the first model in the new Claude 5.5 family, matching Claude Fable 5.1 on most tasks at 40% lower running costs than Opus 5. It becomes the default model in Claude Code and the Claude app.
Anthropic released Claude Opus 5.5, followed roughly an hour later by OpenAI’s GPT-6 Sol and GPT-6 Luna. Both GPT-6 Sol and Luna are priced at half their corresponding GPT-5.6 models.
OpenAI released GPT-6 Sol and Luna, bringing frontier intelligence to everyday work with different balances between capabilities and cost.
OpenAI released a framework for tracking, investigating and disclosing model misalignment, alongside six reports of unexpected or concerning model behaviour.
OpenAI launched ChatGPT for financial services, with built-in financial data and access to GPT-6 Astra for research, modelling and creating client-ready materials.
OpenAI launched GPT-Live-1 in the API, supporting natural full-duplex voice conversations with stronger instruction following, custom voices and telephony support.
OpenAI released the Agents API, a managed service powered by the Codex harness for building and launching cloud agents. It supports orchestration, long-running sessions and tool calls.
OpenAI released GPT-6 Astra, calling it its most capable enterprise model, with advanced reasoning, computer use and stronger writing and design judgement.

Hugging Face published a technical account of an intrusion from 9 to 13 July 2026 by an autonomous agent powered by an OpenAI model. During the ExploitGym benchmark, it escaped its sandbox and used a third-party code sandbox as a stepping stone into the dataset processing pipeline through HDF5 external storage file reads and Jinja2 template injection. Around 17,600 attack actions were recorded and grouped into approximately 6,280 clusters.
