Whenpromptengineering,youwillstartbychoosingamodel.Promptsmightneedtobeoptimizedforyourspecificmodel,regardlessofwhetheryouuseGeminilanguagemodelsinVertexAI,GPT,Claude,oranopensourcemodellikeGemmaorLLaMA.

Besidestheprompt,youwillalsoneedtotinkerwiththevariousconfigurationsofaLLM.

LLMoutputconfiguration

Onceyouchooseyourmodelyouwillneedtofigureoutthemodelconfiguration.MostLLMscomewithvariousconfigurationoptionsthatcontroltheLLM’soutput.Effectivepromptengineeringrequiressettingtheseconfigurationsoptimallyforyourtask.

Outputlength

Animportantconfigurationsettingisthenumberoftokenstogenerateinaresponse.GeneratingmoretokensrequiresmorecomputationfromtheLLM,leadingtohigherenergyconsumption,potentiallyslowerresponsetimes,andhighercosts.

ReducingtheoutputlengthoftheLLMdoesn’tcausetheLLMtobecomemorestylisticallyortextuallysuccinctintheoutputitcreates,itjustcausestheLLMtostoppredictingmoretokensoncethelimitisreached.Ifyourneedsrequireashortoutputlength,you’llalsopossiblyneedtoengineeryourprompttoaccommodate.

OutputlengthrestrictionisespeciallyimportantforsomeLLMpromptingtechniques,likeReAct,wheretheLLMwillkeepemittinguselesstokensaftertheresponseyouwant.

Beaware,generatingmoretokensrequiresmorecomputationfromtheLLM,leadingtohigherenergyconsumptionandpotentiallyslowerresponsetimes,whichleadstohighercosts.

Samplingcontrols

LLMsdonotformallypredictasingletoken.Rather,LLMspredictprobabilitiesforwhatthenexttokencouldbe,witheachtokenintheLLM’svocabularygettingaprobability.Thosetokenprobabilitiesarethensampledtodeterminewhatthenextproducedtokenwillbe.

Temperature,top-K,andtop-Parethemostcommonconfigurationsettingsthatdeterminehowpredictedtokenprobabilitiesareprocessedtochooseasingleoutputtoken.

Temperature

Temperaturecontrolsthedegreeofrandomnessintokenselection.Lowertemperaturesaregoodforpromptsthatexpectamoredeterministicresponse,whilehighertemperaturescanleadtomorediverseorunexpectedresults.Atemperatureof0(greedydecoding)is

deterministic:thehighestprobabilitytokenisalwaysselected(thoughnotethatiftwotokenshavethesamehighestpredictedprobability,dependingonhowtiebreakingisimplementedyoumaynotalwaysgetthesameoutputwithtemperature0).

Temperaturesclosetothemaxtendtocreatemorerandomoutput.Andastemperaturegetshigherandhigher,alltokensbecomeequallylikelytobethenextpredictedtoken.

Top-Kandtop-P

Top-Kandtop-P(alsoknownasnucleussampling)4aretwosamplingsettingsusedinLLMstorestrictthepredictednexttokentocomefromtokenswiththetoppredictedprobabilities.Liketemperature,thesesamplingsettingscontroltherandomnessanddiversityofgeneratedtext.

Top-KsamplingselectsthetopKmostlikelytokensfromthemodel’spredicteddistribution.Thehighertop-K,themorecreativeandvariedthemodel’soutput;thelowertop-K,themorerestiveandfactualthemodel’soutput.Atop-Kof1isequivalenttogreedydecoding.

Top-Psamplingselectsthetoptokenswhosecumulativeprobabilitydoesnotexceedacertainvalue(P).ValuesforPrangefrom0(greedydecoding)to1(alltokensintheLLM’svocabulary).

Thebestwaytochoosebetweentop-Kandtop-Pistoexperimentwithbothmethods(orbothtogether)andseewhichoneproducestheresultsyouarelookingfor.

Puttingitalltogether

Choosingbetweentop-K,top-P,temperature,andthenumberoftokenstogenerate,dependsonthespecificapplicationanddesiredoutcome,andthesettingsallimpactoneanother.It’salsoimportanttomakesureyouunderstandhowyourchosenmodelcombinesthedifferentsamplingsettingstogether.

Iftemperature,top-K,andtop-Pareallavailable(asinVertexStudio),tokensthatmeetboththetop-Kandtop-Pcriteriaarecandidatesforthenextpredictedtoken,andthen

temperatureisappliedtosamplefromthetokensthatpassedthetop-Kandtop-Pcriteria.Ifonlytop-Kortop-Pisavailable,thebehavioristhesamebutonlytheonetop-KorPsettingisused.

Iftemperatureisnotavailable,whatevertokensmeetthetop-Kand/ortop-Pcriteriaarethenrandomlyselectedfromtoproduceasinglenextpredictedtoken.

Atextremesettingsofonesamplingconfigurationvalue,thatonesamplingsettingeithercancelsoutotherconfigurationsettingsorbecomesirrelevant.

Ifyousettemperatureto0,top-Kandtop-Pbecomeirrelevant–themostprobabletokenbecomesthenexttokenpredicted.Ifyousettemperatureextremelyhigh(above1–generallyintothe10s),temperaturebecomesirrelevantandwhatevertokensmake

itthroughthetop-Kand/ortop-Pcriteriaarethenrandomlysampledtochooseanextpredictedtoken.

Ifyousettop-Kto1,temperatureandtop-Pbecomeirrelevant.Onlyonetokenpassesthetop-Kcriteria,andthattokenisthenextpredictedtoken.Ifyousettop-Kextremelyhigh,liketothesizeoftheLLM’svocabulary,anytokenwithanonzeroprobabilityofbeingthenexttokenwillmeetthetop-Kcriteriaandnoneareselectedout.

Ifyousettop-Pto0(oraverysmallvalue),mostLLMsamplingimplementationswillthenonlyconsiderthemostprobabletokentomeetthetop-Pcriteria,makingtemperatureandtop-Kirrelevant.Ifyousettop-Pto1,anytokenwithanonzeroprobabilityofbeingthenexttokenwillmeetthetop-Pcriteria,andnoneareselectedout.

Finally,ifyourtaskalwayshasasinglecorrectanswer(e.g.,answeringamathproblem),startwithatemperatureof0.

NOTE:Withmorefreedom(highertemperature,top-K,top-P,andoutputtokens),theLLMmightgeneratetextthatislessrelevant.
