Claude got a looooot more buy in with a lot of privacy-concerned orgs I work with because they could access it through their "trusted" intermediate Amazon. OpenAI has been banned and is not trusted. I'm not sure that I agree with these orgs' legal teams' assessments, but they definitely read the terms of service far closer than I did.
We will see if this changes the equation, but it feels like OpenAI is pretty far behind and playing catch up on all fronts. Though to be honest, "pretty far behind" is like 2-8 weeks in the AI world, so it may not matter a ton, it's mostly perception. And for me and my information bubble, perception of OpenAI is rock-bottom due to Sam Altman. From appearing unethical to appearing unhinged with demands from fabs and everything else, I'm not a fan.
They're also not focused exclusively only on building an LLM, they have video and image generation too. Anthropic has one single focus, and this is why they are usually at the very top in the SWE benchmarks.
Isn't it the case that OpenAI and Anthropic regularly just swap for whoever is at the top of the latest benchmarks? They're also so close in scores that it's effectively a wash anyways.
What OP is referring to is Anthropic aligning with corporate terms and conditions early, positioning themselves to be effectively resold by AWS rather than requiring orgs to procure them directly. This is huge in the enterprise world because the processes to get broad approval are generally far smaller and shorter for "just another AWS service" compared to a whole new vendor.
Isn't it an open secret that benchmarks are largly irrelevant at this point? Why else we do all have a personalized test battery for new models? That said i've stopped testing chatgpt entierly. Its still ok but is beaten by local models and it gets thrashed by non oai frontier providers. I get the history, but holding up oai outputs as equivallent is lile comparing yahoo to google post yahoo's collapse in search domains.
Oai language models are largly irrelevant at this point imo.
IMHO the benchmarks aren't useful, and ranking among the frontier models is mostly noise. The extra features around the coding agent have a much bigger impact on productivity than having to provide slightly more specification and guidance to the models; a 90% success rate versus a 92% success rate on the tasks I ask it to do is far more influenced by what I say than what the model is capable of.
Open AI is killing Sora though, so it looks like they are looking at Anthropic's playbook of focusing on enterprise use cases and seeing that it's more profitable.
The thing they are really wildly behind on is a business model. They are losing wild amounts of money per customer and it is hard to see how the competitive situation is going to allow them to fix that.
I'm getting pretty close too, but I wouldn't switch to Codex I'd switch to one of the open agents that can use any backing LLM. My reasoning is that if I'm willing to pay the cost of the small changes in usage, I might as well switch to an open source agent that I can add my own convenience features to, like remote sessions and phone-based operation.
Why Codex when you can use something that hasn't been touched by Sam Altman? Surely, your drive to get the very best model isn't stronger than your sense of ethics?
What would be subscription customers, no? Rather than Bedrock or per-api customers? Many of the companies running on Bedrock or by-use have per day limits above the max monthly subscription costs.
It just not about AWS being some "trusted intermediary"... it's that the model runs inside the customer own AWS account under a different contract. AWS explicitly states inputs/outputs are not shared with model providers and are not used to train base models [1]
And for OpenAI, there is a May 2025 preservation order in NYT v. OpenAI. The court is forcing OpenAI to retain ChatGPT output logs indefinitely, including chats users have deleted that would normally be purged within 30 days [2].
That makes it a non starter for HIPAA/GDPR bound orgs.
I'm confused, your own #2 link says that Open AI is not bound to store output logs indefinitely going forward:
> Update on October 22, 2025:
> After months of litigation, we are no longer under a legal order to retain consumer ChatGPT and API content indefinitely. Our obligations under the earlier order ended on September 26, 2025.
> We’ve returned to our standard data retention practices :
> Deleted ChatGPT conversations and Temporary Chats will be automatically deleted from our systems within 30 days (opens in a new window).
> API data will also be automatically deleted after 30 days.
As someone who works at big tech and spends countless hours in meetings hoping to get some small feature coordinated for deployment across two teams, I can't imagine the amount of meetings and 6-pagers that were involved in running these models on bedrock's hardware.
at this level they just decide and spin up a swat team to execute it in a couple weeks without politicking. the bureaucratic ways, reviews are just for the low levels, to keep them busy with feature scraps while they mostly do operations
Lol, spinning up swat teams because someone high up decides "drop everything this is my pet priority now" is politicking. It looks good for the leaders, meanwhile its the engineers pulling the all nighters and dealing with having to maintain systems that are operationally compromised from day 0 because there's no proper planning/scoping involved other than "Big Man says this needs to be done in 2 weeks"
Depends on how its implemented, but Amazon already did add gpt-oss-20b so if the model is similar enough to the OSS variant of GPT, it might not have been as complicated as you might think.
Remember that models on different inference platforms might not necessarily give exactly the same results, adding another axis of non-determinism to development. Things like quantization, custom model serving silicon, batching, or other inference optimizations might mean a model from the original provider performs differently from the hosted one :/
This paper isn't the exact same scenario, since it's an auditable open weight llama model, but shows the symptoms of this: https://arxiv.org/pdf/2410.20247
Availability through Bedrock has been a major driver in use of Anthropic in my org. And I am betting there is actual margin in it as well.
I wonder if this is directly linked to the split up with Microsoft. Just from my anecdata, OpenAI is getting completely ignored in serious enterprise deployments because what they offer on Azure sucks and there is no other corporate friendly way to get it. They probably saw themselves getting destroyed in enterprise and realised it was existential to be able to compete with Anthropic on AWS.
Great, I can now buy openAI through AWS with an interface that is totally incompatible with all my tools (unless AWS have finally given up and just made bedrock useful by adopting openAPI finally)
> Starting today, @awscloud and OpenAI are bringing the latest OpenAI models to Amazon Bedrock, launching Codex on Amazon Bedrock, and launching Amazon Bedrock Managed Agents, powered by OpenAI (all in limited preview). AWS and OpenAI will continue to bring the latest advances to Amazon Bedrock—so the models and agents you build with today continue to benefit from new breakthroughs as they arrive.
A lot of companies already have data processing agreements and compliance sign-off for using AWS. Many are hesitant to send their data to AI startups with an incentive to train their models and a history of being.... loose with how they intake training data. Even when they do give assurances otherwise. AWS is more trusted in this aspect.
If this ends up similar to Claude on Bedrock, it's the same price.
This is for people who don't trust openAI with their data, but do trust Amazon.
But it also is for Devs in a company who already have a blanket agreement with Amazon, but would have an uphill battle signing an agreement with openAI.

Given the scaling hurdles Claude Code / Opus is having, those Anthropic customers might leave to Codex. I'm _this_ close.
Codex is pretty good. Its friction to switch but I think it’s sensible being across multiple AI toolchains.
Pi mono.
Nuff said
This is what I use now after testing others through 2025
It has the most "UNIX" feel of a simple app that you compose the just right flow from and nothing more

My reasoning is that if I'm willing to pay the cost of the small changes in usage, I might as well switch to an open source agent that I can add my own convenience features to, like remote sessions and phone-based operation.
Codex is open source and allows any model to be configured.
Many thanks for that info!
Why Codex when you can use something that hasn't been touched by Sam Altman? Surely, your drive to get the very best model isn't stronger than your sense of ethics?
Codex is not open source. And it's not even that extensible
https://github.com/openai/codex
Codex CLI is open source. Codex the AI model is not. So you're absolutely right, but parent was talking about the CLI harness.

Sure, but also...
...anyone with a brain at AWS knows that supporting OpenAI's latest models on Bedrock is simply good for AWS. That context is rather important!
Depends on how its implemented, but Amazon already did add gpt-oss-20b so if the model is similar enough to the OSS variant of GPT, it might not have been as complicated as you might think.
I imagine there's lots of custom kernels and optimization...
Openai hasn't been publishing innovations for quite a while.
Neither has anthropic.
They're both just stealing ideas from pimono extensions

Anyone who has used gpt-x via openai vs microsoft has experienced this very clearly.
Availability through Bedrock has been a major driver in use of Anthropic in my org. And I am betting there is actual margin in it as well.
I wonder if this is directly linked to the split up with Microsoft. Just from my anecdata, OpenAI is getting completely ignored in serious enterprise deployments because what they offer on Azure sucks and there is no other corporate friendly way to get it. They probably saw themselves getting destroyed in enterprise and realised it was existential to be able to compete with Anthropic on AWS.
It seems pretty clear that OpenAI renegotiated their agreement in preparation for this:

This would be a nice compliance win. One less sub-processor and all our data is already on AWS so less worrying about sending it off somewhere else
Well that didn't take long.
It probably did, but the PR stream that the public sees is a well oiled machine.
This HN post itself has 4 simultaneous announcement links; not a coincidence.
There are billions of investor money on the line if the wrong thing is said at the wrong time, it needs to be carefully crafted and staged.
The market might be increasingly hard on AI startups in general as enterprises adopt providers like Amazon Bedrock and refuse to sign other deals.
OpenAI frontier models coming to Bedrock soon?

We've updated the title above to make that clearer.
Since the product doesn't seem to be available yet, and the other links are all press releases, we'll leave the interview up as the main link.
This doesn't mean you have the raw model weights, right? That's still entirely hidden / opaque?
You can just run "air gapped" inference?
Is this only of interest to enterprise customers already on AWS (who want "air gapped" behavior)? Is there any other use case for this?
This will be more expensive than calling OpenAI directly, right?

Now they are ruining amazon too. It's fascinating to see.
AI is kind of like the ultimate corporation drug. They are all on it. And can't get rid of it - ever again.
