In a recent blog, Timothy Chapman and I introduced techniques to evaluate large language models #LLMs to “test the once untestable” and build more trust in GenAI #TrustinAI. 

We discussed three main testing approaches with "LLM as a judge" generating significant interest as #AItestingAI #LLMJudge.

We've had many follow-up discussions, including live projects, highlighting the significant potential of "LLM as a judge" for:

  • Scaling up developer testing, user-acceptance testing and model validation
  • Generating data to evaluate LLM outputs
  • Monitoring the performance of LLM-powered GenAI apps

At the same time, we always emphasise using other testing and evaluation methods alongside "LLM as a judge" and prioritising Responsible AI Governance #RAI.

Given the ongoing interest, we’ve created a short video of a ”JudgeLLM” testing a “Candidate LLM".  The candidate being tested is an LLM powered Summarisation GenAI App. It's summarising a short document, so we can demonstrate one of our #PwC LLM testing Apps, in less than 90 seconds on LinkedIn.

If you would like to see more on our "LLM as a Judge" technology and its potential for testing your own full-scale LLM use cases - please contact Timothy Chapman, me, or any of our colleagues below.

During PwC’s #TrustinAI event last week and with our sponsorship of the #AISummit this week - I’ve had so many interesting discussions on #GenAI with clients, alliance partners, colleagues, academics and regulators, that I was keen share my 5 key reflections:

(1) Show the #Value - I’m feeling optimistic that we’ll soon see a wave of firms successfully scaling-up. But, for this to happen, AI leaders must quickly show the value for their organisations, stakeholders and society.  All the costs of transformation, tech, cloud, tokens, data, #TrustinAI governance, sandboxing and people & change are adding up - so we must show value, and show it fast.

(2) #Climate & #ESG - The impact of GenAI on climate change must become a core component of #ResponsibleAI (RAI).  It is already part of the discussion, but it quickly needs to be brought right to the forefront of RAI - especially as more firms move to scale-up and our GenAI energy consumption increases.

(3) #People and #Culture - In one discussion, with someone from the #InstituteoftheFuture, they insisted on calling AI #AugmentedIntelligence which I liked. A reminder that AI should help us do our jobs better and faster, rather than replacing us - let’s embrace GenAI and infuse into our team and work cultures.

(4) Talk about #UseCases - I often find that the discussions on GenAI use cases create the most energy and engagement. My favourite AI use cases: (i)  Clinical diagnosis - having benefited from it personally; (ii)  Optimisation of energy and power consumption - to my point above on climate impact; and  (iii)  #AvatarBots… sharing an idea for the future. These could be like ChatBots on steroids. Imagine speaking with an AI generated avatar, that is authentic and you trust and could give you hyper-personalised service and advice.

(5) #GenAITesting #Community - There’s a rapidly growing community who see that the testing of GenAI models is going to be so important to #TrustinAI and RAI.  I may be biased, because It’s one of the most interesting areas I’ve ever worked in, and I’m excited to see where we can take it.

It would be great to hear your reflections and let me know if you want to discuss, or please do comment below. Also, keep an eye out for the latest blog on #GenAITesting from Timothy Chapman which we will launch on LinkedIn next week 🚀 .
