OpenAI Acquires Developer Tooling Startup Astral
AI Secret reports multiple industry moves: Cursor launched Composer 2, a self-built coding model that reportedly outperforms Opus 4.6 on benchmarks while cutting token prices to roughly $0.50 per million input tokens and $2.50 per million output tokens; it also introduced a faster variant and a training method where the model writes its own summaries for long tasks. Separately, OpenAI announced plans to acquire Astral and integrate its tooling into Codex; Astral provides core Python tooling (uv, Ruff, ty) with over 100 million monthly downloads and Codex has surpassed two million weekly users. Cloudflare says it is preparing to manage rising agent traffic by shipping agent sandboxes, execution layers and crawler controls and notes it fronts roughly 20% of the web. Industry leaders at GTC signalled a shift from model-only competition to system construction, orchestration and agent control as a new focal layer.
Acquisition strengthens a major AI platform's developer tooling and product (Codex), signaling continued M&A-driven consolidation in the developer-facing AI market and potential competitive impact among AI copilots.

OpenAI Acquires Astral to Boost Developer Tools Team
OpenAI announced it will acquire Astral, an open-source developer tools provider, to integrate Astral’s Python tooling into its Codex ecosystem. Astral maintains widely used Python projects such as uv, Ruff and ty; OpenAI says it will continue to support these open-source products after the deal closes. The acquisition is intended to accelerate Codex development and extend AI capabilities across the software development lifecycle, enabling deeper integrations so Codex-based agents can work directly with developer tools. Codex has seen 3x user growth and a 5x increase in usage year-to-date and reports over 2 million weekly active users. The transaction is subject to customary closing conditions, including regulatory approval, and Astral’s team will join OpenAI’s Codex group after closing.
OpenAI Acquires Ona to Boost Codex Agents
OpenAI announced it will acquire Ona, a startup that provides secure, pre-configured cloud environments for AI agents. OpenAI said Ona’s technology will let its coding assistant, Codex, handle longer-running tasks and help organizations deploy autonomous agents into production. The companies did not disclose financial terms; the deal is subject to customary closing conditions and Ona’s staff will join OpenAI’s Codex team once closed. Codex has grown to more than 5 million weekly active users. The move follows several recent OpenAI acquisitions as the company expands its developer and agent capabilities amid competition from rivals such as Anthropic.
OpenAI scales Codex to enterprises with Codex Labs
OpenAI reports rapid growth in Codex usage—weekly developer users rose from over 3 million to more than 4 million within two weeks—and says enterprises are expanding Codex across software lifecycles and non-engineering workflows. To accelerate adoption, OpenAI launched Codex Labs, a hands-on program that embeds OpenAI experts in organizations to run workshops, identify high-value use cases, and help move pilots to production. OpenAI is also partnering with global systems integrators (GSIs) including Accenture, Capgemini, CGI, Cognizant, Infosys, PwC and Tata Consultancy Services to scale deployments. The post cites customer examples (Virgin Atlantic, Ramp, Notion, Cisco, Rakuten) using Codex for test coverage, code review, feature development, repository reasoning, and incident response, and includes a quote from Lan Guan, Accenture’s Chief AI Officer, on productivity gains.
