Template:M intro work Large Learning Model

LLM
/ɛl ɛl ɛm/ (also “large language model”) (n.)
Once upon a time, an LLM was a “Master of Laws”: the postgraduate mark of the sensei in the society of legal service providers — either of that, or of the indolence of one not prepared to strike out and put what she has learned into practice — but still: it spoke to perseverance, depth, comprehension and mastery, however pigeon-hearted its motivation.

If the thoughtleaderati are to be believed, now all one needs for that kind of expertise is a different kind of “LLM”: a “large language model”. Artificial intelligence rendered by a pattern-recognising, parallel-processing chatbot.

The legal profession is to ChatGPT, we hear, as poor old Chrissie Watkins was to Jaws.

But there have been contumelious prophecies of its demise before. In the manner of a blindfolded dartsman, Professor Richard Susskind OBE has been tossing them around for decades. Just by random chance, you would expect one to hit the wall at some point.

Is this big law’s Waterloo? Will ChatGPT do for our learned friends what the meteor did to the dinosaurs?

Or will the lawyers, like cockroaches, survive? Might they even turn this to their advantage?

Cui bono?

Who benefits, primarily, from this emergent technology? Experience should tell us that the first — and often the last — to benefit from legal productivity tools are the lawyers. Should we expect this time be different?

Now, it is a truism that she who has a tool uses it, firstly, to improve her own lot. A commercial lawyer’s “lot” is predicated on two things: (1) time taken, and (2) ineffability: the sense that what she does “passeth all muggle understanding”.

It is a happy accident that, generally, (2) begets (1): the more ineffable something is, the longer it takes, and the harder it is to work with. The longer it takes, the more you can charge.

Commercial legal contracts are like that. Long, and once they have calcified into templates, fiddly. For lawyers, this is a capital state of affairs. It is why no commercial law firm on the planet really cares for plain English. Oh, they all say, they do, of course — but come on.

This is, in itself, a neat “simplification defeat device”: if you make a contract template sufficiently convoluted, the one-off cost of simplifying it so vastly outweighs the cost of just “tweaking” and living with it that few clients will ever take that first step to simplify. Even though the the ongoing costs of not rationalising dwarf the one-off costs of doing so, the long-term savings are always over that hump.

And bear in mind it will be the lawyers who deploy LLMs as a tool, not their clients. Why? Because of that ineffability. An LLM is a pattern-matching device. It understands nothing. It cannot provide unmediated legal advice. It can only ever be a “back-breaker”: the “last mile” needs a human who knows what she is doing, understands the context and complicated human psychology at play in the cauldron of 1 negotiation. An LLM can draw pretty, impressive-at-a-distance doodles, but it cannot do that. Nor can it write legal opinions — well, not meaningful ones — and nor, unmediated by a law firm, does it have the insurance policy or deep, suable pockets for which a client is paying when it seeks legal advice in the first place.

An LLM can only be deployed, that is to say, by someone with skin in the game; who is prepared to put herself in jeopardy by accepting the assignment, which jeopardy she defends by the simple expedient of knowing what she is doing and checking her LLM’s output.

That someone will be a lawyer.

Now such a “last mile” lawyer could use an LLM to simplify documents, accelerate research and break legal problems down to their essences, thereby reducing the cost, and increasing the value, of her service to her clients. And, sure: in theory, she could give all this value up to her clients for nothing.

But she could, just as easily, use an LLM to further complicate the “work product”: to overengineer, to convolute, to invent options and cover contingencies of minimal utility: she could set her tireless symbol-processing engine to the task of injecting infinitesimal detail: she could amp-up the ineffability to a level beyond a normal human’s patience.

Which of these, realistically, should we expect a lawyer to do? Simplify, or complicate? Sacrifice time and ineffability, for the better comprehension of the unspecialised world? Or plough the energy this magical new tool bestows into generating more convolution and ineffability, racking up more recorded time?

She would do the latter with only the best intentions, of course; this is not lily-gilding so much as a noble outreach toward perfection: using the arsenal at her disposal to reach ever closer to the Platonic form.

Cynical, or just realistic? Foretellers of legal Armageddon must explain away some difficult facts: that the commercial-legal industrial complex has stubbornly resisted all attempts at simplification and disintermediation for a generation, notwithstanding the thought-leadership, regulatory prompting, appeals to logic 40 years of technology — Microsoft Word, mainly — which the world’s lawyers could have used, powerfully, to simplify and minimise the legal work product.

Not only did the industry not simplify, it made everything more complicated. Boilerplate blossomed. Templates flowered. Every contract acquired wording dealing with counterparts, governing the form of amendments and excluding third party rights that weren’t there in the first place.

Why should a difference engine designed to generate plausible-sounding but meaningless text be used do anything different? You can see the effect LLMs are having on legal work product. NDAs are growing longer and increasingly riven with the same generic convolutions: ornamentations that are usually harmless, but in some cases misconceived but they recur so frequently now, as the LLMs hone their model, so become harder and harder for the meatware to resist. The meatware, remember, has limited patience with NDAs, understanding how much of a pantomime they are. Algorithms, on the other hand, do not understand this and have unlimited patience and boundless energy. If negotiation comes down to who blinks first, we should bear in mind that LLMs don’t blink.

Who’s client? Oh, right: she’s a lawyer, too.

“But, JC, come on. Be realistic. It is dog-eat-dog out there. Any lawyer keeps the bounty of the LLM from her clients will soon have her lunch eaten by others who won’t. You cannot fight the invisible hand. We are in a race to the bottom.”

But are we?

Ignoring how impervious to the invisible hand all other recent technologies have been, remember who the clients are. Consumers of high-end commercial legal services are not, generally, the permanently bamboozled muggles of common myth. Most are themselves lawyers, inhabiting weaponised legal departments mainly comprised of veteran deal lawyers. These are people also take pride in their ability to work with difficult, complicated things. This is how they prove their worth to their employers.

Lawyer and their clients, that is to say, have a common interest in convolution for its own sake. They are the jazz aficionados of text; cinéastes of syntax. They expect overwrought contracts: nothing says “prudent management of existential risk” like eighty page of 10pt Times New Roman.

Plain English is not for serious people.

Conservative motivation

Nor should we underestimate the overwhelming power of the lawyer’s intuition that what has gone before is sacrosanct.

Lawyers are the last great positivists: they understand instinctively that what has been already laid down by someone else — “posited” — is safer and than anything new that they might themselves contribute. The common law with its doctrine of precedent, after all, is to all intents a divine commandment: in times of doubt, to do what has been done before.

The more authoritative the source, the more sacred it will be.

Thus, lawyers will assiduously “track the wording of legislation” to ensure their drafting matches it with utmost fidelity, notwithstanding any private reservations they may have about how it was drafted. The more ambiguous, or just difficult the source text, the more assiduously should we expect lawyers to replicate it, because they fear it. They fear the limits of their own mastery.

This “positivism-through-fear” extends with equal force to established market precedents. It doesn’t matter how manifestly unfit for purpose it is, the resistance to change will be strong.

Meet the new boss —

We don’t doubt that LLM is coming, nor that the legal industry will find a use for it: just that there is a useful, sustained use for it. It feels more like a parlour trick: surprising at first, diverting after a while, but then the novelty wears off, and the appeal of persevering with what is basically a gabby but unfocussed child wears pales.

The traditional legal model faces existential challenges for sure, but they are not presented, and will not be addressed by random word generators.
