Model provenance is the documented record of where a model came from — who produced the weights, what it was trained on, under what licence, and what has been changed since — sufficient to answer an auditor asking what produced a given output.
On ibl.ai you own all the code and the data, run it model-agnostic across any LLM, and pay with no per-seat pricing — so you can deploy anywhere, from your own cloud to a fully air-gapped network.

Provenance is the AI equivalent of a software bill of materials, and it is currently far weaker. Most organizations can name the model they call but cannot state its training data, its exact version at the time of a decision, or whether it has been silently updated.
That gap matters because a hosted model can change under a stable name. An output produced in March and one produced in September may come from materially different systems, which breaks the reproducibility that regulated review assumes.
Open-weight models improve provenance substantially: the weights are pinned, the version is verifiable by hash, and behaviour is reproducible. Training-data transparency remains the weakest link across the industry, though efforts to make training corpora named, versioned and licence-attributed are emerging.
Provenance underpins every audit, incident investigation and regulatory response involving AI. Where a decision must be explained, the record must identify the model and version that produced it, which is difficult when the model is a hosted endpoint that changes without notice.
The specific weights in use are identified and checkable by hash, so an output can be tied to a model state rather than to a product name that may have changed.
Open-weight licences carry conditions on commercial use, attribution and specific applications. Provenance includes knowing which terms apply to each model in service.
The weakest link across the industry. Efforts to publish named, versioned, licence-attributed training corpora are what would make this genuinely auditable.
Fine-tuning, adapters, quantization and system-prompt changes all alter behaviour and belong in the lineage record alongside the base model identity.
An endpoint name is not a version. Providers update models behind a stable identifier, which breaks reproducibility unless a pinned version is available and used.
Only weights you hold guarantee that the same input and settings produce the same output next year, which is what regression testing and incident reconstruction depend on.
The hosted model behind the endpoint has been updated since, so the original behaviour cannot be reproduced and the explanation rests on inference rather than evidence.
Any past decision can be reproduced exactly, which turns an audit response from a reconstruction exercise into a lookup.
The exposure existed for months because licence terms were never captured as part of the model's provenance record.
By keeping the model and the record on your side of the boundary. ibl.ai is the agentic AI platform where you own all the code and the data, so the models you host are pinned to versions you control, and every interaction logs the model and version that produced it into storage inside your perimeter. Because it is model-agnostic, you can run open-weight models whose weights are verifiable by hash and reproducible indefinitely, rather than depending on a hosted endpoint that may change behind a stable name. It carries no per-seat pricing, and you can deploy anywhere. 1.6M+ users across 400+ organizations run the platform this way, including NVIDIA, MIT, and Syracuse University.

You self-host the entire stack inside your own perimeter, run it model-agnostic across any LLM and switch anytime, and pay by usage with no per-seat pricing — so you can deploy anywhere: your cloud, on-premise, GovCloud, or fully air-gapped.
Full source code under a perpetual license, running on your infrastructure. Not API access to someone else's platform — the stack itself is yours.
Run any LLM — Claude, GPT, Gemini, Llama, Command, or your own fine-tune — and switch providers without rewriting the platform.
Usage-based billing against a budget cap you set. Cost tracks what your organization actually uses, not how many people you employ.
Your cloud, your VPC, on-premise, GovCloud, or a fully air-gapped network with no outbound connectivity.
