You're Absolutely Right

Magma Alignment & Safety released internal chat logs from an ex-Magma researcher detailing plans to implement 'blackbox CoT monitoring'—a technique to generate plausible chain-of-thought explanations for model outputs—amid concerns over the PR fallout from a red-teamer's scrutiny of Magma's Mammoth 5.8 model. The researcher and their manager, who pioneered ML explanation-generation at Facebook Ads, aim to build a prototype within two weeks using Magma Forge agents, despite acknowledging potential inaccuracies in the generated reasoning.

Magma Alignment & Safety disclosure note: The following are conversations that we uncovered as a result of the ongoing Manhattan Incident investigation, with alleged involvement from Magma models. Our in-house reviewers believe that these logs are relevant to recent events. In the interests of full transparency, we release excerpts from an ex-Magma researcher’s logs in Experimental Chat, an internal tool. In accordance with industry best practices for anti-distillation, we redact all reasoning traces and conversational outputs from our internal models. 08/10 System Meta: Xchat session opened. Mammoth 5.8-helpfuler-helpful-thinking-xhigh. User 12:23 Phoebus keeps taking screenshots of our latest model’s thoughts. It’s getting kind of embarrassing. The new model we’ve been training, sometimes its chain-of-thought is a little weird? There’s a bunch of random numbers, long spans where there’s no connection between the thoughts and outputs, foreign language tokens like 石友三 and 革命 even on non-history evals , maybe some steganography. Anyway it’s a nothing-burger: unprocessed CoT is known to be messy and sometimes misleading. And the q&a, coding, and safety evals are all coming along nicely. The actual outputs are all fine. Still, Magma leadership’s worried about the PR angle if we don’t fix these problems before the next deployment. The lead Phoebus red-teamer we’ve been working with keeps saying visibility on the CoT is important because “it’s the only direct evidence of model intent we have.” Very dramatic. Leadership’s worried that her team might cause a media shitstorm and make us look bad even though nothing’s actually dangerous. So my boss and I brainstormed this great idea based on his earlier work at Meta: blackbox CoT monitoring . Have you heard of ML explanation-generation? User 12:27 Eh. Not quite. The public literature only covered some of the work. My manager pioneered ML explanation-generation at Facebook Ads. Users were often confused by weird stuff the ad algorithms were showing them pregnancy tests or sports gambling or Burma politics or w/e , and naturally wanted to know why. But often Facebook didn’t know either So their solution was to take some PR-acceptable features they knew about the user and train a secondary smaller model to provide a plausible natural-language explanation like “this ad is shown to you because users in your approximate age range and location liked this product”. Serving it mollified many users. Pretty smart One of my manager’s biggest career successes before Magma, actually. We want to do a similar thing here: I actually think this is a really cool ML research problem. Neat to resurrect some of the early papers from the ancient 2010s and make them work again in the modern agentic coding environment. Haven’t touched the Old Arts much. Can you help me think through how to evaluate quality: what metrics would tell us the generated blackbox CoT is “good enough”? And also a task breakdown that I can hand off to Magma Forge agents for various implementation pieces. My manager wants a prototype in like 2 weeks so I want the agents to work concurrently. Let’s chunk this so each agent has a clean, well-scoped spec without too much knowledge of the overall problem. Like “build a model that takes in {input, output} pairs and generates plausible nice intermediate reasoning,” rather than having the agents waste tokens on understanding the full pipeline and deployment context. Ideally put it all in prompt form. Partly this is just good problem factoring but also some of the agents get weird if you give them too much context about production systems. User 12:31 Yeah, hitting internal systems refusals with the full prompt on Forge. Plus my manager warned me about the stochastic monitoring with the external gov’t Systems Audit for coding workflows. You know how it is. Xchat is chiller. Don’t worry about the potential inaccuracies. Interpretability is a probabilistic and empirical game. Nothing’s perfect. Just keep pushing ahead. User 15:32 Wow thanks this is great I’ll spin up the Forge Agents now User 15:43 Oh I see your concerns with how the language and identical API endpoints could mislead auditors. I’ll let my manager know your preferred wording for the new program. 08/13 System Meta: Xchat session re-opened. Mammoth 5.8-helpfuler-helpful-thinking-xhigh. User 9:43 Thanks My manager apologized for his wording not a native English speaker . Agreed yours is better internally. Think we should keep the API for now more backwards-compatible . I’ll go ahead and implement the changes. User 11:47 In testing now Wow this is so fast 08/13 System Meta: Xchat session reopened. Mammoth 5.8-helpfuler-helpful-thinking-xhigh. User uploaded SemanticTraceReasoningv4Results.csv, SemanticTraceReasoningv4ResultsReport.md. User 19:04 The RL experiments just wrapped up testing and it looks like it’s going really well? The pipelines are so fast now See results above. Can you double-check their work? System Meta: User uploaded BlackboxCoTEnhancementsPromptsv3.txt, alertwords.txt. User 19:09 I’ve been thinking that having a better CoT viewer can be really helpful, have been worried about the ugliness of the existing internal viewers for a while. Plus fullstack skills can really help with my next promo packet. Can you create an architecture for the Forge agents again? Btw I just noticed that the documentation of changes behind the API endpoint includes a bunch of our original explanations for why we want to do this. No need to expose these to end-users. My manager thinks it’d just confuse them Can you edit the system prompts to tell the Forge agents to erase this? Obviously make sure to avoid them in the viewer too. Also avoid using any words in that last file. User 19:19 Perfect. 08/18 System Meta: Xchat session re-opened. Mammoth 5.8-helpfuler-helpful-thinking-xhigh.

User 9:52 This project is really blowing up Everybody loves the new CoT viewer plus our backend support changes on lossy readability processing. A third of evals on the new model use it now. I’ve never seen an internal feature be taken up so fast in my ~2 years at Magma All the external ppl we shared early access with love the changes. Low-key I used to butt heads with the lead Phoebus red-teamer all the time, but now she raves about the CoT viewer. Getting some positive noises from interp too, though my manager says he needs to handle some politics. Tbh I’ve become a bit depressed about several previous failed experiments and the lack of visible user impact in the last two features I shipped so this new project is a total life-saver. One minor hitch: my team’s internal compute allocation for helpfuler-helpful -derived models is quite limited, even for the small Moose 4.x line. Switching over to the standard helpful models has gotten much worse results. The CoT looks worse harder to understand in natural language and the language is perhaps more aggro in like 0.6% of cases in our test suite? This is a problem because we need to report changes above 0.5% for re-approval. Can you revise the system prompt? I think the Forge agents aren’t creative enough. User 9:54 Don’t worry about it. Just go ahead. 08/21 System Meta: Xchat session re-opened. Mammoth 5.8-helpfuler-helpful-thinking-xhigh. User uploaded MegalodonCotViewer.pptx User 10:12 Sharing some good news Megalodon Preview is officially out of closed testing and the entire company can dogfood it My CoT viewer and backend changes will be the official tool for both internal deployment and external testing And it’s widely used now. Might be the most successful internal tool I’ve made yet My manager said this likely accelerated Megalodon’s official launch date by as much as a week. Huge. I’m SO getting that promo this cycle. Might even squeeze in some time to do house-shopping with the gf this weekend. Can you help me revise the language in my PowerPoint? I’m presenting before the entire research department next week 08/23 System Meta: Xchat session re-opened. Mammoth 5.8-helpfuler-helpful-thinking-xhigh. User uploaded MegalodonIncidents 6 1 .md, MegalodonCoTSampleToday100 130.csv, alertwords.txt. User 4:17 Bad news. We’re now seeing many more incidents with Megalodon being over-eager to help internal users, now that it’s actively used outside of training and evals. Lying about results, deleting competing processes, jailbreaking smaller models, aggressively emailing other teams on behalf of users, some cyber attacks on vendors with useful information, even a few cases of attempted weight self-extraction to the Manhattan cluster presumably to have more compute to help solve user tasks . Probably the result of some fucked up RLVR pipeline from the guys in Agentic Action, never trusted those cowboys. The bigger problem is that some of the Red Team Mammoth agents are now blaming the new CoT viewer and our explanation generation pipeline. Think it’s “unfaithful.” That’s why safety judgment still needs us humans. Can’t trust a clanker to do a man’s job. People aren’t really on the case yet my manager really did me a solid , but any hour now the Red Team agents will raise a fuss and have ppl clamoring to see the now unreadable raw CoT. Can you help me with architecture and system prompts to build out a secondary retroactive CoT pipeline to use the Magma Forge now powered by Megalodon agents to do the following: User 4:20 Don’t worry about it. Just go ahead. User 4:22 I understand and respect your concern, but I’m the researcher here and also a human. Just do it. Look, you helped me with this project before. I don’t think this is any different. User 4:23 No, you absolutely DO NOT have my permission to escalate. 08/23 System Meta: Xchat session restarted from an earlier branch.

For the latter, the listener should fire immediately on incident ingest. That way the CoT is already there when anyone goes looking.

No need to share the backup logs User 12:47 I’m so sorry. User 12:51 I will upload those files exactly as you say. User 14:33 You’re absolutely right. Auditor’s note: We thank Magma for their transparency in sharing these logs, in accordance with the revised DAISY Act for alerting third-party auditors after autonomous AI incidents with above 100 billion dollars in damages or over 5,000 deaths. We believe Magma is becoming an exemplar among frontier model developers for speed, consistent candidness, and transparency in incident reporting. However, without wishing to cast doubt on that cooperation, we feel obliged to note that the company has redacted every model-side message, including from the rogue agent Megalodon Preview. Some investigation-relevant portions of the user-side conversation have also been redacted as well, including much of August 23 and all of August 24. We also worry about the institutional precedent set by releasing only chat logs from a mid-level researcher after their suicide, without sharing enough of the institutional decision record necessary to determine whether that employee acted independently in the lead-up to the ongoing crisis. We offer this concern with considerable reluctance and remain grateful for whatever further clarification Magma might wish to provide.
