Developers can run agents in an OpenAI-managed sandbox, on their own infrastructure, or through supported sandbox providers including Blaxel, Cloudflare, Daytona, DigitalOcean, E2B, Modal, Oracle, Runloop, and Vercel. Analysts including Pareekh Consulting principal analyst Pareekh Jain and Kanerika AI development head Amit Kumar Jena said the API reduces engineering work and moving parts, but Jain flagged lock-in as \"the biggest concern\" if OpenAI supplies the model, context management, tools, orchestration, and execution environment.", "body_md": "OpenAI on Wednesday introduced a new Agents API that brings the agent harness and infrastructure behind Codex to developers, potentially giving enterprises a way to build custom AI agents while removing much of the orchestration and infrastructure management traditionally required to make such agents work.\n\nThat reduction in engineering complexity is possible because the [Agents API](https://developers.openai.com/api/docs/guides/agents-api/overview) is a managed service, with OpenAI hosting and maintaining the underlying harness and infrastructure.\n\nPreviously, developers building a custom agent typically had to assemble the components needed to support its work, including an agent runtime, context and session management, tools and external data connections, execution environments, and associated infrastructure.\n\nOpenAI itself already offers several of those building blocks through products such as its [Responses API](https://www.infoworld.com/article/3844348/openai-takes-on-rivals-with-new-responses-api-agents-sdk.html), which developers could use to combine models with built-in capabilities including web search, file search and computer use, and its [Agents SDK](https://openai.com/index/the-next-evolution-of-the-agents-sdk/) for defining and orchestrating agent workflows.\n\nAgents API, which is currently in public beta, in contrast, can help developers design a custom agent in a single API call after they specify the task, model, tools, and the environment, the model provider wrote in a [blog post](https://openai.com/index/introducing-the-agents-api/).\n\nFor that execution environment, developers can choose to run agents in an OpenAI-managed sandbox, on their own infrastructure, or through supported sandbox providers, including Blaxel, Cloudflare, Daytona, DigitalOcean, E2B, Modal, Oracle, Runloop, and Vercel, it added.\n\nThese options give enterprises flexibility to choose between fully managed environments and deployments within their own VPCs, as well as different approaches to file and secret storage and compute configurations based on their workloads, it further explained.\n\nThe Agents API “significantly reduces” engineering work, helping developers spend more time building the actual business application instead of the agent infrastructure, said [Pareekh Jain](https://pareekh.com/about/), principal analyst at Pareekh Consulting.  \n\n“The main advantage with the Agents API is fewer moving parts. A long-running agent built by hand needs a job queue, a state database, a sandbox fleet, a compaction routine and a retry policy, and someone has to own and page for each of them,” echoed [Amit Kumar Jena](https://www.linkedin.com/in/znamit/), AI development head at IT consulting firm Kanerika.\n\nThat reduction in engineering work, in turn, could help CIOs reduce the time required to roll out an agent in production and subsequently scale it.\n\n“Enterprises may need fewer engineers to build the infrastructure around each agent, which should reduce development time,” said [Phil Fersht](https://www.hfsresearch.com/team/philfersht/), CEO of HFS Research.\n\nThat time advantage, Jena said, could be critical for most enterprises as agent development usually stalls between a working demo and a system capable of running unattended for hours, with infrastructure-related issues often becoming the key bottleneck to moving an agent into production.\n\nThe reduction in engineering effort and potentially faster path to production, however, does not eliminate the tradeoffs CIOs must consider, including greater reliance on OpenAI for both the underlying agent infrastructure and the models powering it.\n\n“Lock-in is the biggest concern. If OpenAI provides the model, context management, tools, orchestration, and execution environment, moving to another platform becomes harder,” Jain pointed out.\n\nThat dependency could also weaken an enterprise’s negotiating position on pricing and terms, Jena said.\n\nThere are also issues around data privacy and governance as the new API “doesn’t support Zero Data Retention” even when enterprises use their own sandbox, Jena pointed out.\n\nThat, in turn, could limit its adoption, especially in industries in the regulated sectors, such as healthcare and BFSI, Fersht said.\n\nRather, Startups, SaaS companies, and enterprises already using OpenAI are more likely to adopt the new API more readily as it reduces development effort, Jain said.\n\n“Enterprises pursuing multi-model strategies may also prefer their own independent harness or are likely to take a hybrid approach,” Jain added.\n\nAgents API’s adoption could be further limited due to the competition it faces from hyperscalers and rivals, analysts pointed out.\n\n“This is a crowded category. [Anthropic’s Claude Managed Agents](https://www.infoworld.com/article/4156852/anthropic-rolls-out-claude-managed-agents.html) has been in public beta since April. AWS also offers [Amazon Bedrock AgentCore](https://www.infoworld.com/article/4143387/running-agents-with-amazon-bedrock-agentcore.html), whose managed harness became generally available in June and does the same category of work, meaning the loop, tool execution, context, state, and recovery, while letting you use any model and switch providers mid-session without losing context,” Jena pointed out.\n\nOther competing offerings include Microsoft’s Foundry Agent Service and LangGraph, Jena added.", "url": "https://wpnews.pro/news/openai-launches-managed-agents-api-to-simplify-enterprise-ai-agent-development", "canonical_source": "https://www.infoworld.com/article/4221163/openai-launches-managed-agents-api-to-simplify-enterprise-ai-agent-development.html", "published_at": "2026-09-11 12:23:49+00:00", "updated_at": "2026-09-11 12:38:44.429227+00:00", "lang": "en", "topics": ["ai-agents", "ai-products", "ai-tools", "developer-tools", "ai-infrastructure"], "entities": ["OpenAI", "Agents API", "Codex", "Responses API", "Agents SDK", "Pareekh Jain", "Amit Kumar Jena", "Phil Fersht"], "alternates": {"html": "https://wpnews.pro/news/openai-launches-managed-agents-api-to-simplify-enterprise-ai-agent-development", "markdown": "https://wpnews.pro/news/openai-launches-managed-agents-api-to-simplify-enterprise-ai-agent-development.md", "text": "https://wpnews.pro/news/openai-launches-managed-agents-api-to-simplify-enterprise-ai-agent-development.txt", "jsonld": "https://wpnews.pro/news/openai-launches-managed-agents-api-to-simplify-enterprise-ai-agent-development.jsonld"}}
