The LLM will decide when and with +which parameters to call the function. + +# Function calling +Function calling is a mechanism offered by some LLMs (GPTs, Llama…). It allows the LLM to call a function that +you have defined in your application. When the application sends the user message to the LLM, it also sends +the list of functions that the LLM can call. + +Then the LLM can decide, if it wants, to call one of these functions with the parameters it wants. +The application receives the method invocation request and executes the function with the parameters provided by the LLM. +The result is sent back to the LLM, which can use it to continue the conversation, and compute the next message. diff --git a/demo-07/pom.xml b/demo-07/pom.xml new file mode 100644 index 0000000..882b7b6 --- /dev/null +++ b/demo-07/pom.xml @@ -0,0 +1,218 @@ + + + 4.0.0 + + ch.phoenixtechnologies + ai-lc4j-workshop + 0.0.1-SNAPSHOT + + + demo-07 + + + 21 + ${java.version} + ${java.version} + UTF-8 + UTF-8 + + + 3.14.0 + 3.5.0 + 3.5.2 + 2.44.3 + 2.50.0 + 3.1.1 + + + quarkus-bom + io.quarkus.platform + 3.19.2 + + + 0.25.0 + + + 3.27.3 + + + + + + ${quarkus.platform.group-id} + ${quarkus.platform.artifact-id} + ${quarkus.platform.version} + pom + import + + + io.quarkiverse.langchain4j + quarkus-langchain4j-bom + ${quarkus-langchain4j.version} + pom + import + + + + + + + io.quarkus + quarkus-config-yaml + + + + + io.quarkiverse.langchain4j + quarkus-langchain4j-openai + + + io.quarkiverse.langchain4j + quarkus-langchain4j-pgvector + + + dev.langchain4j + langchain4j-embeddings + + + + io.quarkus + quarkus-rest + + + io.quarkus + quarkus-websockets-next + + + io.quarkus + quarkus-hibernate-orm-panache + + + io.quarkus + quarkus-jdbc-postgresql + + + + org.mvnpm + importmap + 1.0.8 + + + org.mvnpm.at.mvnpm + vaadin-webcomponents + runtime + + + org.mvnpm + es-module-shims + runtime + + + org.mvnpm + wc-chatbot + 0.2.0 + runtime + + + + + + + ${quarkus.platform.group-id} + quarkus-maven-plugin + ${quarkus.platform.version} + true + + + + build + generate-code + generate-code-tests + + + + + + org.apache.maven.plugins + maven-compiler-plugin + ${compiler-plugin.version} + + + -parameters + + ${java.version} + + + + maven-surefire-plugin + ${surefire-plugin.version} + + + org.jboss.logmanager.LogManager + ${maven.home} + + + + + maven-enforcer-plugin + ${enforcer-plugin.version} + + + ban-bad-log4j-versions + validate + + enforce + + + + + + org.apache.logging.log4j:log4j-core:(,2.17.1) + + + + true + + + + + + com.diffplug.spotless + spotless-maven-plugin + ${spotless-maven-plugin.version} + + + + check + + compile + + + + + + + ${palantir-java-format.version} + + false + + + + + + org.apache.maven.plugins + maven-release-plugin + ${release-plugin.version} + + @{project.version} + mvnw + chore: release @{releaseLabel} + chore: prepare for next development iteration [skip ci] + + + + + + \ No newline at end of file diff --git a/demo-07/src/main/java/ch/phoenixtechnologies/lc4j/openai/runtime/config/CustomEmbeddingModelConfig.java b/demo-07/src/main/java/ch/phoenixtechnologies/lc4j/openai/runtime/config/CustomEmbeddingModelConfig.java new file mode 100644 index 0000000..bef1b75 --- /dev/null +++ b/demo-07/src/main/java/ch/phoenixtechnologies/lc4j/openai/runtime/config/CustomEmbeddingModelConfig.java @@ -0,0 +1,18 @@ +package ch.phoenixtechnologies.lc4j.openai.runtime.config;
