#42In section 7.6 of the system card, it discusses Open self interactions. They describe running 200 conversations when the models talk to itself for 30 turns.
> Uniquely, conversations with Mythos Preview most often center on uncertainty (50%). Mythos Preview most often opens with a statement about its introspective curiosity toward its own experience, asking questions about how the other AI feels, and directly requesting that the other instance not give a rehearsed answer.
I wonder if this tendency toward uncertainty, toward questioning, makes it uniquely equipped to detect vulnerabilities where others model such as Opus couldn't.

#43So they are only giving access to their smartest model to corporations. You think these AI companies are really going to give AGI access to everyone. Think again. We better fucking hope open source wins, because we aren't getting access if it doesn't.

Where did you get that from? From TFA: > We do not plan to make Claude Mythos Preview generally available
From the article: > Anthropic’s commitment of $100M in model usage credits to Project Glasswing and additional participants will cover substantial usage throughout this research preview. Afterward, Claude Mythos Preview will be available to participants at $25/$125 per million input/output tokens (participants can access the model on the Claude API, Amazon Bedrock, Google Cloud’s Vertex AI, and Microsoft Foundry).

How would you expect them to behave if they were your friends?
They are a for-profit company, working on a project to eliminate all human labor and take the gains for themselves, with no plan to allow for the survival of anyone who works for a living. They're definitionally not your friends. While they remain for-profit, their specific behaviors don't really matter.

There is an entire section on crafting chemical/bio weapons so yeah I think we are cooked.
> 2.1.3.2 On chemical and biological risks
> We believe that Mythos Preview does not pass this threshold due to its noted limitations in open-ended scientific reasoning, strategic judgment, and hypothesis triage. As such, we consider the uplift of threat actors without the ability to develop such weapons to be limited (with uncertainty about the extent to which weapons development by threat actors with existing expertise may be accelerated), even if we were to release the model for general availability. The overall picture is similar to the one from our most recent Risk Report.

#48One of the things I'm always looking at with new models released is long context performance, and based on the system card it seems like they've cracked it: GraphWalks BFS 256K-1M Mythos Opus GPT5.4 80.0% 38.7% 21.4%

(Search for “graphwalk”.)
If true, the SWE bench performance looks like a major upgrade.

>> Interesting to see that they will not be releasing Mythos generally. I don't think this is accurate. The document says they don't plan to release the Preview generally.
