  • EU AI Act Conformity for Self-Hosted LLMs: What Your Evidence File Must Prove

    The EU AI Act's December 2027 deadline for high-risk AI systems looks distant on a roadmap — but with notified body queues already growing and harmonised standards still being finalised, the organisations that will be ready are the ones assembling their evidence files now. This episode of LLM.co walks through the full conformity assessment requirements for self-hosted LLMs, cutting through the policy noise to focus on what a market surveillance authority would actually demand to see.

    The episode covers the full arc of Article 43 conformity for enterprise LLM deployments — from the legal triggers that push a system into Annex III high-risk territory, to the structural compliance advantages of owning your own inference stack. Key topics include:

    • Why the internal control lane is not the easy lane: Self-assessment under Annex VI eliminates the need for a notified body, but it transfers the entire evidentiary burden to the deploying organisation — including a quality management system, risk management file, and a signed declaration of conformity available on demand.
    • Annex IV, section by section: Each of the nine documentation sections maps to concrete artefacts for a self-hosted model — build manifests with cryptographic hashes, base model provenance, fine-tuning dataset lineage, RAG index composition, and retrieval policy, among others.
    • Where evidence files most often fall apart: Auditors cross-reference the design section, the changelog, and the monitoring logs — and gaps between those three sources are where assessments become adversarial.
    • Self-hosting as a structural compliance advantage: Unlike public API deployments — where provider and deployer can end up pointing at each other under Article 3 — a self-hosted stack gives one accountable provider, immutable WORM logs, version-pinned model artefacts, and a single tenant of record for data residency.
    • Article 72 post-market monitoring done right: A quarterly review or an unwatched dashboard does not satisfy the requirement. The episode details the closed-loop signals regulators expect — including embedding drift, refusal-rate deviation, calibration drift on labeled probes, and jailbreak-signature detection — all tied to documented corrective action.
    • Penalty context for board-level conversations: Fines for high-risk violations are material, and prohibited-practice breaches can reach €35 million or seven percent of global annual turnover — making the cost of a defensible evidence file straightforward to justify.

      • More from the show: if your organisation relies on third-party model providers, the earlier episode Why DeepSeek's China Data Storage Policy Is an Enterprise Red Flag covers exactly the kind of supply-chain accountability gaps that make self-hosting a compliance imperative, not just an architectural preference.

    • Why DeepSeek's China Data Storage Policy Is an Enterprise Red Flag

      DeepSeek has earned real attention for its speed and accessibility, but its privacy policy contains a detail that enterprise teams cannot afford to overlook. This episode of LLM.co examines the data storage risks behind DeepSeek's China policy and explains why where an AI platform stores your data matters just as much as what it can do with it.

      The conversation covers the full arc of the problem — from the legal mechanics of Chinese data sovereignty to the practical compliance exposure facing organizations in regulated industries:

      • The core policy clause: DeepSeek explicitly states that user data may be processed and stored on servers located in the People's Republic of China, making jurisdiction a concrete, documented fact rather than an abstract concern.
      • Why location equals legal exposure: China's Cybersecurity Law and Data Security Law grant government agencies broad authority over data held within Chinese borders — regardless of where that data originated or who owns the company.
      • Collision with Western compliance frameworks: GDPR, HIPAA, and ITAR each impose strict controls on where and how sensitive data can travel; routing regulated information through Chinese servers can constitute a direct regulatory violation.
      • The prompt-training risk: Beyond storage, inputs submitted to third-party LLM platforms may be used for model fine-tuning or retraining — meaning confidential contracts, trade secrets, or patient data could be ingested into systems operating under foreign jurisdiction with no recovery path.
      • The broader lesson: DeepSeek is a vivid example, but the data-location question applies across all third-party AI tools; most organizations haven't fully audited where their AI-processed data actually lives.
      • What a safer path looks like: Private deployment — on-premises, in a sovereign cloud, or within a controlled virtual private cloud — with local vector databases, encrypted ingestion, and no outbound data calls to external infrastructure.

        • Before committing to any LLM platform, the episode recommends asking three non-negotiable questions: Where is the data stored? How is it processed? Who could access it under the governing jurisdiction's laws?

      • How Enterprises Are Using Local LLMs for Fraud Detection

        Global fraud losses are on track to surpass half a trillion dollars, and the rigid, rules-based detection engines that financial institutions have trusted for years simply can't keep up. This episode of LLM.co explores how enterprises are deploying local LLMs to fight financial fraud — examining why on-premises AI is becoming the competitive edge for compliance-conscious organizations facing increasingly sophisticated threats like synthetic identity schemes, deepfake voice fraud, and sleeper-bot attacks.

        The episode unpacks the full case for local large language models in enterprise fraud detection, covering:

        • Why legacy rule engines are failing: Hard-coded logic can't adapt fast enough as fraud tactics mutate hourly — every patch creates a new gap for bad actors to exploit.
        • How local LLMs reason across richer data: Rather than matching transactions to fixed conditions, these models detect probabilistic anomalies across payment rails, device telemetry, CRM notes, and support transcripts — often before any analyst spots a trend.
        • The data-privacy advantage: Because the model runs entirely inside an organization's own infrastructure, raw customer data never crosses an external wire — turning compliance from a liability into a competitive strength.
        • A dramatic drop in false-positive triage: Research shows alert fatigue — the single largest drain on analyst hours — falls by more than a third after a local LLM joins the fraud stack, freeing teams to focus on genuinely ambiguous cases.
        • Explainability that enables human oversight: Instead of opaque risk scores, analysts receive plain-language rationale for each flag, making confident overrides possible and feeding corrections back into the model as evidence.
        • Governance built for regulators: Every inference can be written to an immutable, timestamped ledger — compressing compliance reviews from months to days and delivering the reproducible audit trails regulators increasingly demand.

          • The episode also addresses the two most common implementation pitfalls: overfitting to historical attack patterns (solved by holding out recent validation slices and injecting synthetic "canary" scenarios) and the organizational gap between data scientists and frontline fraud operators (closed with structured cross-functional syncs that keep model tuning aimed at real bottlenecks). Together, these disciplines separate institutions that merely experiment with local LLMs from those that deploy them at production scale.

        • Debugging Hallucinations in Open Source Models

          Hallucinations — confident, fluent, and factually wrong AI outputs — are among the most damaging trust failures in production systems. This episode of LLM.co draws on the full guide to debugging hallucinations in open source models to walk through why these failures happen and, more importantly, how to trace them back to their root causes rather than chasing individual bad outputs.

          Language models don't retrieve facts — they predict likely text. Fluency and accuracy are not the same thing, and users routinely mistake a confident tone for a verified answer. Teams working with open source models have real leverage here, but only if they approach the problem systematically. The episode covers:

          • Why hallucinations cluster into types — missing knowledge and reasoning errors require different fixes, and conflating them leads teams to pile in more documents when the actual problem lies elsewhere.
          • How prompt design quietly invites invention — vague instructions like "explain fully" push models toward gap-filling; well-constructed prompts give the model explicit permission to express uncertainty or stop.
          • The role of retrieval and context quality — bloated, conflicting, or loosely related source documents can produce blended, incoherent answers that have nothing to do with the model's underlying capability.
          • Document chunking as an underappreciated culprit — overly aggressive splitting strips surrounding context from retrieved fragments, leaving the model to complete pictures it was never given enough of.
          • Generation settings and their real tradeoffs — temperature affects variation, not truthfulness; a stable hallucination repeated consistently is still a hallucination, and settings should be matched deliberately to the use case.
          • Fine-tuning and evaluation blind spots — training examples that reward completeness over accuracy teach models to fill gaps; evaluation sets that don't reflect messy real-world queries will miss the failures that matter most in daily use.

            • The throughline across all of these is that groundedness — whether a model's output is actually supported by available sources — is a more honest signal than helpfulness alone. A model that always produces detailed answers may score well on surface-level metrics while quietly eroding user trust every time those details are invented.

          • Why AI Projects Fail Organizationally Before They Fail Technically

            Technical performance is rarely what kills an AI initiative. This episode of LLM.co examines the organizational and structural breakdowns that derail AI projects long before a model ever has a chance to prove itself — drawing on the full analysis of why AI projects fail organizationally before they fail technically. From how goals get defined to how tools get adopted, the conversation surfaces the patterns that repeat across teams and industries.

            The episode walks through the most common organizational failure modes, covering:

            • Vague goals that invite misalignment — when a project's objective is broad enough for every stakeholder to project a different vision onto it, teams end up building toward multiple imaginary finish lines simultaneously.
            • Leadership enthusiasm without hard decisions — pressure to "move fast and innovate" without clear constraints produces systems that try to impress everyone and genuinely serve no one.
            • Missing success metrics — launching before defining what improvement looks like means even a high-performing model can't demonstrate its own value; metrics tied to real business outcomes give a project its spine.
            • Diffused ownership — steering committees, working groups, and shared inboxes can coexist with a total absence of anyone empowered to make a call, causing decisions to slow and projects to drift.
            • Late involvement of subject-matter experts — technical teams that polish a product before real users weigh in are really just deferring expensive rework; the people who do the work know where the edge cases hide.
            • Adoption failures that outlast launch day — users don't adopt AI tools because of a well-designed announcement; they adopt them when the tool removes friction from tasks they already care about, and training only works when it connects to those specific tasks.

              • The episode also addresses data problems that look technical but are really human disagreements — two departments using the same field name to mean different things — and the underrated role of practical governance: straightforward rules about what the AI should and shouldn't do, when a human must review an output, and who is accountable when something goes wrong. Without those guardrails, teams improvise every edge case at full cost.

            • CAPEX vs OPEX in Open Source AI: Why the Hybrid Wins

              When an AI project moves from demo to daily infrastructure, the conversation shifts fast — from model benchmarks to balance sheets. This episode of LLM.co tackles one of the most consequential decisions in any open source AI deployment: how you pay for it. Drawing on the in-depth guide to CAPEX vs. OPEX in open source AI, the episode cuts through the accounting jargon and explains how the choice between owning infrastructure and renting it shapes not just your first invoice, but your team structure, data control, and total costs for years ahead.

              Here's what this episode covers:

              • What CAPEX actually means for AI teams: Buying GPUs, servers, and networking gear upfront trades a painful year-one bill for long-term cost efficiency — but only if workloads are steady, large, and well-managed.
              • The hidden operational burden of ownership: On-premise infrastructure demands technical maturity; hardware that nobody has the expertise to optimize is just an expensive liability.
              • Why OPEX lowers the barrier — and raises the risk: Cloud and managed hosting let teams experiment without permanent commitments, but usage can compound quietly until a "flexible" bill becomes anything but.
              • The myth of "free" open source: Eliminating licensing fees doesn't eliminate compute, storage, security, or engineering costs — treating open source as free just turns those costs into surprises.
              • How to make a meaningful cost comparison: A true CAPEX vs. OPEX analysis spans three to five years and factors in depreciation, staffing, vendor fees, scaling costs, and downtime risk — not just year one.
              • Why the hybrid model wins: Matching financial structure to workload behavior — CAPEX for stable, high-volume jobs; OPEX for experiments and burst capacity — lets organizations grow into ownership with real usage data rather than optimistic projections.

                • The episode also explores how open source AI's flexibility (the ability to tune, compress, and host models across environments) makes a hybrid strategy more viable than it would be with proprietary tooling — reducing vendor lock-in and giving finance and engineering teams a shared language for long-term planning.
