IWF: 6,310 AI child sexual abuse images assessed in six months, 40% above all of 2025
The Internet Watch Foundation assessed 6,310 AI-generated child sexual abuse images between 1 January and 30 June 2026, against 4,512 in all of 2025. It is a count of what analysts assessed, not of what exists, and the UK offence for abuse-image generators is enacted but not yet in force.

Six months set against twelve
On 5 October 2026 the Internet Watch Foundation (IWF) said its analysts assessed 6,310 AI-generated images that met the legal definition of child sexual abuse between 1 January and 30 June 2026. For all of 2025 the same release gives 4,512. The difference is 1,798 images, or 39.8 per cent (derived: 6,310 divided by 4,512 is 1.398). The IWF rounds that to 40 per cent, and the arithmetic holds.
The detail that matters is the clock. The 6,310 covers 181 days and the 4,512 covers 365. Per day that is 34.9 images against 12.4, about 2.8 times the pace (derived, and it assumes images were assessed evenly through each period, which the IWF does not state). The Guardian's standfirst and picture caption say "this year". The IWF's own release says the first half. Nothing after 30 June is in the number, and the release came 97 days later.
What the number does not establish is what most readers will take from it. It is not how much of this material exists, because it counts what analysts assessed. It is not how many children are affected: the IWF says of its 2025 data that some children appear repeatedly, so the figures do not necessarily represent unique individuals. And it does not say whether the rise reflects more material, better detection, or more searching and reporting. The IWF said of its 2025 video total that it is influenced by where its analysts look and what the public reports. The 5 October release makes no such statement about the 2026 image count. Silence is not evidence either way. This briefing applies the same caution to images, as an inference.
What each number counts
The IWF's unit in this release is the image, not the web page, the report or the child. Its methodology page says hash-level data allows more precise trend analysis than URL-level data, where a single web page may hold hundreds or thousands of images. It also says identical files share a hash and need not be assessed again, and that changing one pixel produces a different hash. Inference: re-edited variants of one picture can each count as a new image. How the 2026 count treats near-duplicates is not stated, and it matters most for a technology that makes variants cheaply.

Two points on where the Guardian's pieces come from. First, the release is addressed to Brussels: it urges EU policymakers to agree the Child Sexual Abuse Regulation so that platforms can detect known and previously unseen material. It does not ask for UK legislation on AI. The call for "binding legislation on AI" is a quote the Guardian attributes to the IWF's head of policy, so it rests on that report. It is consistent with the IWF's annual report, which calls for a "regulatory requirement to ensure AI products are safe by design". Second, the Guardian's Report Remove figures (420 against 397) are from a different IWF release, of 10 August, and count children's reports, not images.
Reconciling the time frames, and the IWF's two totals for 2025
The Guardian's two time frames. Its body text says the first half of 2026, which is correct. Its standfirst and caption say "this year", and the standfirst says the number is "already" 40 per cent above last year's total. Read against the release, "this year" means 1 January to 30 June. So the comparison is half a year against a whole one. That does not weaken the finding, since the first-half total already exceeds the full-year total. It does mean the pace is faster than the 40 per cent suggests, and that the three months from 1 July to the release are not covered at all.
The IWF's two totals for 2025. The release says analysts identified 4,512 images in 2025. The annual report, read on 5 October 2026, says 4,586. They are 74 apart, 1.6 per cent of the larger. The release does not say why. The annual report says 180 of its 4,586 were grid images (single images made of several), and whether the 4,512 leaves anything out is not stated. The choice moves the headline: against 4,586 the rise is 37.6 per cent, not 39.8. The release's own 2025 Category C share points the same way. It says 2,842 images, 62 per cent. That is 61.97 per cent of 4,586 and 62.99 per cent of 4,512, which would round to 63. Inference: the release's percentage appears to use the annual report's total while its headline uses another. The Guardian's "more than 4,500" fits both.

What changed inside the count, and why synthetic is not victimless
The release's breakdown does not show the rise concentrated at the most severe end. Category C, the lowest of the three gradings in the Sentencing Council's guidelines and still criminal, was 5,557 of the 6,310 images, 88 per cent. In all of 2025 it was 2,842. Categories A and B together were 753 images in the half year. For all of 2025 they were about 1,670 (derived: 4,512 less 2,842, or 1,744 on the 4,586 total). The annual report put Category A at 23 per cent of AI images in 2025; in the first half of 2026 it is 350 of 6,310, or 5.5 per cent (derived).
That does not show the worst material fell. In 2025 the IWF found that 65 per cent of AI-generated videos were Category A, and the 2026 video figures are not in this release. The release does not say whether severe material moved out of still images, whether analysts' priorities changed, or whether the mix reflects what is being made or what is being found.
Age and sex moved in one direction. Images of children aged seven to 13 were 79 per cent of those with both recorded, up from 70 per cent across 2025. The IWF reports 1,004 images depicting children aged three to six and 190 aged under two in the half year. Girls were 98 per cent of the 6,221 with both recorded, against 97 per cent in 2025, and the number of unique images depicting girls rose from 4,259 to 6,094.
"AI-generated" is not a safe word. It suggests no victim and no offence. The sources say otherwise. The IWF's release states that AI-generated child sexual abuse imagery "causes real harm", and that in some cases offenders use AI tools to manipulate genuine images of victims. Its annual report says images of real children are often used to train models. UK law does not treat the label as a defence. A realistic AI image falls within the pseudo-photograph definition in section 7(7) of the Protection of Children Act 1978, an image which "appears to be a photograph", and the government's factsheet says such images are most likely treated as pseudo-photographs. The 1978 Act makes it an offence to make, distribute or possess one with a view to distributing it, with up to ten years on conviction on indictment. Non-photographic images fall under section 62 of the Coroners and Justice Act 2009. The government's own factsheet says the law is clear that creating, possessing or distributing such images, AI-generated or not, is already illegal.

Method, not accusation. The IWF is a charity that assesses this material, and its numbers come from trained analysts, not from a model. It is also funded in part by its members, who buy its services, including a hash list it markets to generative AI model providers, and it campaigns on legislation. This release is one part of a push on the EU Child Sexual Abuse Regulation: the IWF launched a campaign to EU citizens and MEPs on 14 September 2026, ahead of negotiations. None of that is a reason to doubt that analysts assessed 6,310 images. It is a reason to read each figure for what it counts, and to note that no independent audit of the 2026 count was found.
What UK law does today, and what is enacted but not in force
The Guardian says the government "has also made it illegal to adapt an AI model" to create abuse material, with up to five years for developing a model designed to produce hyper-realistic material. The Crime and Policing Act 2026, which received Royal Assent on 29 April 2026, does create an offence of that kind. On legislation.gov.uk at 08:00 BST on 5 October 2026, section 72 is marked prospective, with the note that it was "not in force at Royal Assent". Most of the Act starts on a day the Secretary of State appoints (section 255). Three sets of commencement regulations have been made, on 25 June, 25 August and 2 September 2026. None lists section 72. Nobody can be charged under it today, on the evidence of those pages. A commencement order could change that at any time, so check before relying on this.

Three phrases in the Guardian's paragraph need care. First, "has made it illegal": enacted, not commenced. The offences that apply to images today are the 1978 and 2009 provisions, and the 1978 Act carries up to ten years against up to five for the model offence. Second, "a model designed to produce hyper-realistic" material: the statute does not use those words. Section 46A catches a thing "made or adapted for use for creating, or facilitating the creation of" such images, and "thing" includes "a program, information in electronic form and a service". The Explanatory Notes say this captures models optimised to create abuse material and also "wider technologies that can be used to create this content, such as CGI programmes". The government's factsheet says the offence "will not criminalise AI developers" and is aimed at offenders who optimise models for this purpose. Whether a general-purpose image tool is caught turns on whether it was made or adapted for that use. An online safety commentator calls that unclear, and no court has tested it. Third, "up to five years": that is on conviction on indictment. A director or manager who consents to or connives at an offence by a company also commits it (section 46C).
The government's own route for AI services is separate. Section 248 inserted a power into the Online Safety Act so that the Secretary of State can, by regulations, impose illegal content duties and the NCA reporting duty on AI services. GOV.UK's press release of 15 February 2026, filed under the 2024 to 2026 Labour government, promised to "move fast to shut a legal loophole". The IWF's 10 August release refers to "a new Government". The Guardian reports that the current government has not signalled an AI bill, and that the AI minister said nothing is off the table. A bill is not the only route. Section 249 requires a progress report by 31 December 2026, 87 days from 5 October, unless draft regulations are laid first. No draft regulations were found.
What Ofcom expects, and where its reach stops
Ofcom said on 3 February 2026 that chatbots are outside the Online Safety Act if they only let a person interact with the chatbot and no other users, do not search multiple websites or databases, and cannot generate pornographic content. Images a chatbot creates without searching are not generally in scope, unless they are pornographic, in which case they must be age-gated, or can be shared with other users. Ofcom added that it was "currently unable to investigate the creation of illegal images by the standalone Grok service in this case". That is the gap the section 248 power is meant to close, and it is open today.
If your service has UK links and lets users share what a tool creates, or is a search service, the illegal content duties apply. In practice that means an illegal content risk assessment, updated before a significant change, and the Illegal Content Codes of Practice in force since 17 March 2025. Measure ICU A2 asks every service to name an individual accountable for illegal content safety duties. Measure ICU C9 recommends perceptual hash matching of images communicated publicly, for services at high risk of image-based abuse material that have more than 700,000 monthly UK users or are file-storage and file-sharing services, and for large services (more than 7 million monthly UK users) at medium or high risk. The hash set must come from an expert source that identifies material correctly and keeps its database up to date. ICU C10 does the same for listed URLs. Ofcom can fine up to 18 million pounds or 10 per cent of qualifying worldwide revenue, whichever is greater.
Ofcom has used this. On 13 October 2025 it reported that two file-sharing services it had identified as concerning deployed perceptual hash-matching after its enforcement programme, and it took no further action against them at that time. It opened a formal investigation into X on 12 January 2026 over sexualised imagery made through Grok. At the last Ofcom update I read, of 3 February 2026, that investigation was ongoing, and I found no published outcome.
Hash matching only stops what has already been identified. The IWF's release says so itself: new content has no existing hash until someone has assessed it. Ofcom proposed in June 2025 that services at the applicable risk level deploy proactive technology to detect unknown image-based material as well. That consultation is marked Pending Statement. In its statement of 18 May 2026, updated 9 September, Ofcom said it expects to publish its decision on those other measures in autumn 2026. Until then, detecting new AI-generated material is not a measure in Ofcom's Codes, so a service that meets ICU C9 has met the Code and still has no recommended measure aimed at new AI-generated images that no hash list has seen.
The EU adds a date. Regulation (EU) 2026/1744 inserts Article 5(1)(bb) into the AI Act from 2 December 2026, 58 days from 5 October. It prohibits placing on the market, putting into service or using an AI system that generates or manipulates child sexual abuse material, where that is the intended purpose or where it is a reasonably foreseeable and reproducible outcome and the system lacks reasonable and adequate safeguards. The recital lists safeguard types: data cleaning, refusal training, safe prompt design, output controls, content classification and filtering, usage restrictions, abuse detection and notice and action. It also says the prohibition should not prevent legitimate red-teaming and evaluation. An earlier briefing on the AI Act sets out the application dates. A UK organisation placing a system on the EU market is in scope of that date.
What a UK organisation that builds, hosts or deploys image tools should have in place
This is general advice, not legal advice, in the order worth doing. It assumes you run or supply a tool that can generate or host images. Which of the legal duties above reach you depends on the design of your service, and the dividing lines are set out in the Ofcom section. One principle runs through all of it, and an earlier briefing on an Ofcom age-assurance case makes the point: a vendor's tool does not move the legal duty. It stays with you.
Take this with you
Six things to have, in order
- Safety-by-design evidence, written before launch and kept current: what keeps abuse material out of training data and out of outputs, what filters, refusals and usage limits exist, who signed it, and what changed since. Do not test by trying to generate the material yourselves. Creating such an image is itself within section 1 of the 1978 Act, and no testing defence for developers was found in force. The section 111 power needs regulations that were not found. Take legal advice on an authorised route.
- Hash matching for known material, and a plan for the unknown. Use a hash list from an expert source on uploads and inputs, such as the IWF Image Hash List through IWF membership. The IWF sells that service, so weigh its interest; Ofcom's Code requires an expert source, not a particular one. The Code expects this of services in scope. Hash lists cannot see a new image, so test a classifier, record its false-positive rate, and watch for Ofcom's autumn 2026 decision. The duty stays with you, not the vendor.
- Reporting routes, tested. A report route for users, a monitored address for outsiders, the IWF's anonymous report page and the police. If you run a regulated user-to-user service, register with the NCA before you need to report: a senior manager or equivalent as organisation administrator, current contacts, and a response to NCA requests within 7 days.
- Retention and legal hold, written down before an incident. The rule for staff is do not copy it, do not forward it, report it to the IWF and the police. If section 66 applies to you, regulation 8 of the 2026 regulations sets one year for the reported content and related data and five years for the report reference. Take legal advice on how that sits with data protection before anyone builds a store for it.
- Staff welfare and escalation: a named owner, a clear route from the first person who sees something to that owner, and occupational health support arranged before it is needed. List who could be exposed, including moderators, support staff and engineers on call. The IWF's methodology page says it limits what it records on videos to protect its assessors, which shows the principle.
- Contact made before the incident: an IWF membership enquiry, NCA registration if section 66 applies, your own counsel, and a named person who can reach each of them. Keep contact details current.
What could not be verified
The question this leaves
A hash list stops what someone has already seen, and the IWF's count is of images that a person had to see first. The first six months of 2026 already sit 40 per cent above all of 2025. So when the first image your service produces or hosts is one that no list has ever fingerprinted, what in your service catches it, and who has signed the evidence that it works?
