Miasma is an open-source tool that creates honeypot pages designed to trap AI web scrapers in infinite loops of generated nonsense content. It poisons training data by serving plausible-looking but entirely fabricated text, wasting crawler resources and degrading the quality of scraped datasets.

OpenAI released Privacy Filter on April 22, 2026 — a 1.5B-parameter open-weight model for detecting and redacting personally identifiable information from text before it ever reaches a cloud API. The model runs fully locally, handles 128,000 tokens in a single pass, and achieves a 96% F1 score across eight PII categories: names, addresses, emails, phone numbers, URLs, dates, account numbers, and secrets. Unlike traditional regex-based PII scrubbers that choke on unstructured text and context-dependent references, Privacy Filter uses a fine-tuned language model to understand semantic context — it catches "call me at the usual number" type references that pattern matchers miss entirely. The model ships with only 50M active parameters at inference time via sparse activation, keeping latency low enough for preprocessing pipelines. Available on Hugging Face and GitHub under Apache 2.0, Privacy Filter solves a real bottleneck: enterprises and regulated industries have been unable to safely pipe sensitive documents through LLMs at scale. OpenAI explicitly warns it should be treated as a "redaction aid, not a safety guarantee," which is unusually honest for a model card — and a sensible framing for high-stakes medical or legal workflows.
Reviewer scorecard
“Dead simple to deploy — drop it on any server and point suspicious crawlers at it. The infinite page generation is clever engineering. My only gripe is it needs better bot fingerprinting out of the box, but the plugin system lets you extend it.”
“This solves the exact blocker that's kept enterprise AI adoption stuck in procurement hell. A locally-running, 96% F1 PII layer means I can finally build LLM pipelines that touch customer data without the CISO saying no. Dropping this into every preprocessing pipeline starting today.”
“Look, the AI scraping arms race is real and site owners need tools to fight back. Miasma is not going to stop OpenAI, but it will waste their compute and pollute their pipelines. That is genuinely useful leverage. Just do not expect it to be a silver bullet.”
“A 96% F1 score sounds great until you realize that in a dataset of a million healthcare records, 4% miss rate is 40,000 PII leaks. OpenAI's own model card says don't rely on this for high-stakes medical or legal use — so the exact industries that need it most are the ones that can't trust it. Good for low-stakes use, but the marketing oversells the safety story.”
“This is the digital equivalent of booby-trapping your property. As AI companies hoover up the entire web without consent, tools like Miasma shift the power dynamic back toward content creators. Expect to see this pattern everywhere within a year.”
“On-device PII sanitization is the infrastructure layer that lets AI into every regulated industry simultaneously. When this gets embedded into enterprise data pipelines at the OS level, the last major privacy objection to AI adoption effectively collapses. Apache 2.0 licensing means it will be everywhere within a year.”
“Finally I can feed real user research transcripts and customer emails into AI summarization tools without manually redacting them first. The 128K context window means full long-form interviews go in at once. This removes a genuinely painful part of my research workflow.”
