Abstract: A method, computer program product, and computer system are provided for container cross-cluster capacity scaling. The method includes broadcasting local capacity information of capacity availability or capacity requirement for the local cluster and receiving broadcasts from each of one or more other clusters providing capacity information including capacity availability or capacity requirements. The method may map the received capacity information with the local capacity information and may determine a suitable cross-cluster capacity sharing when a capacity requirement of the local cluster maps to a capacity availability of another cluster or when a capacity availability of the local cluster maps to a capacity requirement of another cluster. The method may coordinate the deallocation of a node from the cluster having the capacity availability and reallocation of the node to the cluster having the capacity requirement.

Aspects further include storing the category and the normalized prompt data.

Abstract: Embodiments of the present invention provide computer-implemented methods, computer program product, and computer systems. One or more processors analyze user prompts using one or more natural language understanding techniques. One or more processors then enrich the user prompts by integrating contextual data from user interaction history and adapt the enriched user prompts to align with characteristics of Large Language Models (LLMs) and Application Programming Interfaces (API) requirements of the LLMs.

Abstract: A float collar for use in a wellbore includes: a float valve; a tubular housing having a coupling formed at a longitudinal end thereof for assembly as part of a downhole tubular; a sheath bonding the float valve to an inner surface of the housing within a flow bore thereof, the sheath having a bore formed therein; and a ball deflector seated against a top of the sheath and having: an upper grate and a lower anchor engaged with an inner surface of the sheath adjacent the bore. The float valve, the sheath, and the ball deflector are made from materials drillable by a polycrystalline diamond compact (PDC) drill bit.

Abstract: A computer-implemented method, system, and computer program product for leveraging artificial intelligence to improve operations. An artificial intelligence assistant is created to assist a user in leveraging artificial intelligence to service a request from a user. Furthermore, a request is received from the user, where the request is a request to chat with a context. Context refers to experiences that are utilized by the user for interacting (e.g., chatting) with artificial intelligence, which is used to minimize artificial intelligence hallucinations since such context is used by the artificial intelligence model to output a response thereby providing more confidence that the output response of the artificial intelligence model is more accurate. The request is then serviced by leveraging the artificial intelligence using the context. In this manner, artificial intelligence hallucinations are minimized.

Abstract: Aspects of the invention include techniques for collaborative prompt building for generative artificial intelligence models. A non-limiting example method includes receiving, from a client, a prompt for a large language model. A decision tree is built to determine one or more decision points for refining the prompt and a knowledge graph is built having one or more nodes associated with a feature of the prompt. The method includes delivering, to the client, a challenge comprising a query associated with at least one of the one or more decision points and the one or more nodes, receiving, from the client, an answer to the challenge, and delivering, to the client, a refined prompt by modifying the prompt using the answer to the challenge.
