OpenAI's Codex now runs through Amazon Bedrock, with fewer features and US-only regions

Since June 1, 2026, after an April preview, AWS customers can run OpenAI's Codex coding tool on OpenAI models served by Amazon Bedrock, billed per token through AWS. It follows an April 27 Microsoft–OpenAI rewrite that ended Azure exclusivity and resolved the AWS-exclusivity dispute; Microsoft stays primary cloud partner with a non-exclusive licence to 2032.

The framing"OpenAI Codex on Amazon Bedrock" does describe a real, generally available product open to AWS customers since June 1, 2026. But GPT-5.5 runs in one AWS Region (US East, Ohio), and hosted web search, Fast Mode and some plugins aren't available on Bedrock.

What the headline leaves out

  • Azure stays primary: OpenAI products ship first there, OpenAI keeps a $250 billion Azure commitment to 2032, and Microsoft's 20% revenue cut runs to 2030, now capped.
  • Bedrock Codex lacks hosted web search, Fast Mode and plugins needing ChatGPT authentication; OpenAI says behaviour may differ.
  • GPT-5.5 is offered only in US East (Ohio); GPT-5.4 in Ohio and Oregon.
  • Standard Bedrock rates reportedly match OpenAI's direct global prices, but data-residency endpoints carry a 10% uplift.

What the coverage got wrong

  • Microsoft (public statement): “"Microsoft maintains its exclusive license" to OpenAI intellectual property”. Under the April 27, 2026 rewritten deal, Microsoft holds a non-exclusive licence to OpenAI IP through 2032, which TechCrunch says resolved the AWS-exclusivity dispute.techcrunch.com

Who gains, who loses

WhoHow manyEffect on eachIn or out if
Large AWS-first enterprises and their platform teamsMore than 100,000 organizations already on Bedrock (not all will use it)Use Codex under existing AWS billing, IAM, PrivateLink, encryption and CloudTrail logging; no new vendor or seat licencesIn if already on Bedrock and working in supported US Regions
Small API buyers already using OpenAI directlyNot foundLittle immediate change, per trade press; Bedrock version has fewer featuresLittle gain if they don't need AWS procurement
Customers needing data residencyNot foundInference stays in the selected Region, at a 10% price uplift over direct global ratesPay the uplift if they choose regional/data-residency endpoints
AWS customers outside the US RegionsNot foundGPT-5.5 only in US East (Ohio); GPT-5.4 in Ohio, Oregon and, from June 3, GovCloud (US-West), a separate government Region rather than a standard commercial oneOut for local in-Region use if outside listed Regions
Microsoft (same-package change)One companyLoses cloud exclusivity; keeps capped 20% revenue share to 2030 and may stop paying its revenue share to OpenAIApplies under the April 27, 2026 rewritten deal

What happens next

No further dated step is set; AWS says Daybreak, including cyber models and Codex Security, will come to Bedrock with no fixed date. OpenAI's Help Center says some Codex features depending on OpenAI-hosted services remain unavailable on Bedrock. TechCrunch reports the April 27 rewrite resolved the AWS-exclusivity dispute, though coverage differs on whether AWS's exclusive Frontier rights were fully preserved. Watch for Region expansion, closed feature gaps and Frontier distribution terms.

Possible knock-on effects
  • AWS's exclusive rights to serve OpenAI Frontier, which trade press says appear preserved, could prompt Microsoft to seek further changes, which may force renegotiation and matter to enterprises choosing between Azure and AWS. (precedent: The February 2026 Amazon–OpenAI deal led Microsoft to weigh legal action (first reported March 18, 2026) and was the proximate cause of the April 27, 2026 Microsoft–OpenAI rewrite.. Watch for: A further amended Microsoft–OpenAI agreement or a formal dispute over Frontier distribution.)
  • The 10% uplift on data-residency endpoints could lead cost-sensitive teams without residency rules to use global endpoints or OpenAI directly, which may limit Bedrock's price appeal outside regulated buyers. (mechanism: Follows from OpenAI's published 10% regional-processing uplift; no source forecasts this response.. Watch for: AWS or OpenAI changing regional pricing, or published usage splits by endpoint type.)

The report: what outlets said

A guide on the AWS Builder Center says that sending OpenAI's Codex through Amazon Bedrock "removes OpenAI's hosted API from the request path"[1]

The AWS Builder Center post walks through a small, cross-platform set of scripts that connect Codex to Amazon Bedrock in an India region, so OpenAI-compatible models are served in-country[1]. It notes that any opinions in the article are the individual author's and may not reflect AWS's views[1].The author writes that for regulated or public-sector organisations, using OpenAI's hosted API "can mean source code, prompts, and proprietary context are processed outside your control"[1].Under the setup, the post says models are served from Bedrock in ap-south-1 (Mumbai), with ap-south-2 (Hyderabad) as the in-country cross-Region destination[1]. The "preferred production path"[1] is to put a governance gateway in front of Bedrock, rather than storing long-lived keys on each developer's machine.AWS's machine learning blog said earlier that GPT-5.5, GPT-5.4, and Codex are now generally available on Amazon Bedrock[2]. According to AWS, customers pay per token with no seat licenses and no per-developer commitments[2].When it launched the preview, OpenAI said that all customer data is processed by Amazon Bedrock, and eligible customers can apply Codex usage towards their AWS cloud commitments[3].OpenAI's Help Center warns that some Codex features that rely on OpenAI-hosted cloud services, hosted tools, or cloud-managed tool discovery are not currently available[4] when using Bedrock.
