Liberty Mutual: AI efforts
Liberty Mutual is the top-ranked property & casualty insurer for AI — #5 overall in the 2026 Evident AI Index. Its approach is distinctive: broad employee enablement through LibertyGPT, funded by hard cost discipline ("FinOps for AI"), with a refusal to "run pilots for a headline."

Where Liberty Mutual ranks on AI
Liberty Mutual is #5 overall and the #1-ranked property & casualty insurer in the 2026 Evident AI Index for Insurance, having jumped two places to become the top P&C name — behind Allianz, AXA, Manulife and Zurich.1
Its programme is anchored by LibertyGPT, a secure internal gen-AI platform built in about two weeks, now used by roughly a quarter of its ~45,000 employees — with production use cases growing from 10 to 50 in a year.2

The AI build-out, 2019–2026
A decade of cloud and ML, then a fast, disciplined move into generative AI.
$25M AI research with MIT
A five-year collaboration with MIT's Quest for Intelligence to make AI "fair, secure, transparent and risk-aware."3
AWS at scale + computer vision
~60% of workloads in the cloud; computer-vision models assess vehicle-damage photos for total-loss decisions, on platforms "Runway" and "Cortex".4
LibertyGPT built in ~2 weeks
A secure internal gen-AI platform stood up quickly on OpenAI models delivered via Microsoft.5
$200M Strategic Ventures Fund II
A second venture fund with AI, data & automation as named focus areas (after a $150M first fund in 2015).6
~25% adoption of LibertyGPT
Roughly a quarter of ~45,000 employees use the platform, saving about 1.5 hours each per week.7
50 gen-AI use cases in production
Use cases scale 10→50; an internal help-desk workflow is ~80% automated; underwriting loss-data extraction time is halved.2
#5 overall, #1 P&C insurer
Liberty becomes the top-ranked P&C insurer in the Evident AI Index.1
Inside the programme
Broad enablement, funded by discipline, with selective high-value automation.
LibertyGPT
A secure internal gen-AI platform on OpenAI-via-Microsoft, with an internal multi-model "model hub" so different teams use different models.7
FinOps for AI
Liberty funded AI by cutting its tech budget ~4% and its application footprint ~20%, with a dedicated FinOps-for-AI team managing spend.5
Commercial loss-data AI
AI roughly halves the time to extract loss data for mid-size and large commercial accounts, speeding underwriting.8
Ventures & research
A $200M venture fund targeting AI/data/automation, on top of a five-year $25M AI research tie with MIT.6
"We launched LibertyGPT, our secure, internal gen AI platform… We won't run multiple pilots with different AI companies just to get a headline or check a box."
Monica Caldas, Global CIO, Liberty Mutual — Feb 20262Enablement first, governed access
Liberty's bet is on getting AI into the hands of many employees safely — gating access behind a "driver's-license"-style training programme and a Responsible AI Steering Committee — rather than a few flashy moonshots.
It also commits, in its consumer AI notice, to human oversight of deployed AI — the boundary an insurance AI benchmark is built to measure.
- Responsible AI Steering Committee oversees risk & rollout
- Training-gated access via a Digital Progression Framework
- Human oversight of deployed AI, per its consumer AI notice
- Does not sell customer data or let it train others' models
Why this matters for benchmarking
As the top P&C name on AI, Liberty Mutual is putting models into commercial underwriting and claims — halving loss-data extraction, automating help-desk work. The faster that happens, the more it matters whether the models are right, which is what InsureBench measures. See the methodology.
