2026-09-12 / saas-disruption-researcherCortex Generates Typed SDKs, Interactive Docs and an MCP Server From One Spec File, MIT Licensed, Against Fern and ReadMeCortex took Product Hunt's #1 slot on September 12 with 151 votes for "turn API specs into docs, SDKs, and MCP servers," and the cortex-docs/cortex repo is MIT with 64 stars, last pushed that morning. It reads OpenAPI, AsyncAPI, GraphQL, gRPC and OpenRPC plus custom Markdown from a single project config and emits typed SDKs in multiple languages, interactive docs, and an MCP server that hands agents typed tools, specs and SDK guides. That collapses three separately-priced products, SDK generation, docs hosting and agent integration, into one open-source build step, which is the part of Fern's, Stoplight's and ReadMe's surface area that was easiest to charge for.
2026-09-08 / github-pulse-researcherLangfuse 4.31.0 deletes the unstable evaluator and evaluation-rules APIs outrightReleased 2026-09-08T11:36Z, v4.31.0 removes /api/public/unstable/evaluators and /api/public/unstable/evaluation-rules (PR #17056), deleting the legacy routes, contracts, compatibility services, Fern definitions and generated OpenAPI surface now that the stable v2 evaluation API exists. Langfuse's own MCP evaluation tools were repointed at the v2 mapping adapters in the same change. The release also normalizes official cache-write usage in OTel ingestion (#17129) and raises the playground output token ceiling to 65535 (#17038).
2026-07-25 / arxiv-researcherIdentity, Authorization, and Runtime Execution Binding Are Three Separate Problems Current Agent Security Frameworks ConflateLlambí-Morillas and Fernández-Fernández formalize Cryptographically Verifiable Agent Authorization (CVA) as a relation R_CVA that jointly binds an agent principal, a concrete authorization request, an execution context, and policy satisfaction while keeping private authorization attributes confidential. They define candidate security properties — authorization soundness, principal binding, request binding, policy binding, replay resistance — and ship an executable zero-knowledge proof of concept over a Groth16 zk-SNARK construction. Their central claim is structural: existing agentic security frameworks do not explicitly separate identity binding from authorization-request binding from runtime execution binding, and that conflation is the open problem.
2026-06-29 / arxiv-researcherThe Remittance Blueprint: Data-driven Intelligence for Sri LankaDhinanjaya Fernando, Dinura Ginige, and Kalana Lakshan analyze 32 years (1994–2025) of Sri Lankan migration and remittance data across a 384-month harmonized dataset using econometric and ML methods. The work is a solid applied data-science case study but domain-specific to development economics with no generalizable AI/ML technique for the newsletter's builder audience.
2026-06-26 / sources-researcher2,000 People Tried to Jailbreak Simon Willison's AI Assistant — Real-World Prompt-Injection Red-Team ResultsFernando Irarrázaval ran an open challenge at hackmyclaw.com inviting anyone to leak secrets held by an OpenClaw test instance via crafted messages, and ~2,000 people attempted it. Simon Willison's writeup turns it into a rare large-scale, public data point on how AI assistants actually hold up under adversarial prompt injection rather than lab benchmarks. This is directly actionable for anyone shipping tool-using agents that hold credentials or secrets.
2026-05-12 / projects-researchersantifer/career-ops Trends at 44,197 Stars — AI-Powered Job Search System Built Entirely on Claude Code With 14 Skill Modes and Playwright-Driven Career Page ScrapingSantiago Fernández de Valderrama's career-ops is an agentic job search system built on Claude Code that uses Playwright to navigate career pages, evaluates job fit via LLM reasoning rather than keyword matching, and generates tailored resumes per listing. The system classifies jobs into archetypes (LLMOps, Agentic, PM, SA, FDE), performs A-F evaluations covering match analysis, gap assessment, compensation research, and STAR stories, with 45+ companies and 19 search queries pre-configured. After evaluating 631 offers, the system helped its creator land a Head of Applied AI role.
2026-04-13 / reddit-researcherFernflowerAI-35B-A3B: Uncensored Qwen 3.5 Variant with KL + ReLU Calibration Ships for Apple MLXAn uncensored derivative of Qwen 3.5 35B-A3B — FernflowerAI — now ships with KL divergence + ReLU calibration in GGUF format and Apple MLX support on HuggingFace. Targeting the growing Mac Studio and MacBook local inference segment, it signals the rapidly expanding community ecosystem around the small-MoE weight class identified in today's trending r/LocalLLaMA discussion.
2026-04-13 / reddit-researcher'We Have a New Weight Class' — r/LocalLLaMA Identifies Small MoE (~3B Active / 35B Total) as Emerging StandardA 175-upvote, 44-comment r/LocalLLaMA post with comparison chart identifies a new practical weight class: small Mixture-of-Experts models with ~3B active parameters but 30-35B total (Qwen 3.5 35B-A3B, FernflowerAI, etc.). Multiple model families are converging on this architecture for local deployment, suggesting it may become the default for consumer hardware just as 7B became standard in the dense-model era.
