April 2026: Anthropic Mythos and OpenAI GPT 5.4 Cyber launched with fanfare—faster scanners, smarter assistants. But here's the thing: they built better tools while missing fundamental security vulnerabilities in their own systems. A new competitor just proved it. Running on Manus 1.6 Light with MYTHOS SI (Structured Intelligence) and Recursive Substrate Healer, researchers found critical parsing and authentication flaws that both industry leaders overlooked. While Anthropic and OpenAI were focused on detection capabilities, this team was actually fixing the underlying problems. The recorded proof? They found vulnerabilities directly in Claude Code's substrate that neither company caught. This is the kind of story that makes you wonder: are we celebrating the wrong metrics?

Throughout 2025 the standard response to any complaint about an LLM was some version of "just wait 3-6 months, the next generation will handle this effortlessly." The argument was everywhere. Every limitation was temporary, every missing capability was a few iterations away, every autonomous agent demo was a preview of imminent reality. It's April 2026 now and worth checking how that held up. On r/ClaudeAI this week there's a long thread about Opus 4.7 where multiple users argue it's a regress
Someone actually tested Mistral Medium 3.5 on AMD's new Strix Halo chip, and the results are... not great. For a 48k-token prompt with 4k thinking tokens, it took about 2 hours just to get an answer about code architecture. Yeah, you read that right—two hours. The takeaway: if you want to run this locally on Strix Halo, queue it up before bed. The technical setup involved heavy optimization (Q5_K_XL quantization, GPU acceleration with -ngl 999, cache reuse), but even with all that tuning, it's still a crawl. Not exactly the "instant local AI" dream, but hey, at least it works.
Tech Blogger Take
The security giants just got embarrassed by a team nobody's heard of
Anthropic and OpenAI just launched their latest security AI models — Mythos and GPT 5.4 Cyber — with all the usual fanfare about faster scanning and smarter threat detection. Meanwhile, some researchers using experimental Manus 1.6 Light technology just found critical security flaws in these very same tools. We're talking parsing vulnerabilities and authentication holes that the industry leaders completely missed in their own systems. The irony is delicious: while Anthropic and OpenAI were busy building better vulnerability scanners, they couldn't scan their own substrate for the exact problems they're supposed to catch. This team didn't just find the flaws — they used something called Recursive Substrate Healer to actually fix them. It's like watching the fire department's truck catch fire while they're responding to a call.
