Ollama enables type-safe JSON output with schema-constrained decoding
Ollama has introduced a new `format` parameter that accepts a JSON schema, enabling constrained decoding during LLM inference. This feature significantly improves the reliability and speed of obtaining structured JSON o…
-
AI agents struggle with semantic tool selection despite schema validation
A developer found that strict schema validation for AI agent tool calls did not significantly reduce failures, as most errors were semantic rather than structural. The majority of issues involved the agent selecting the…

Developer suggests pre-call Pydantic schema validation for LLMs
A developer shared a technique to improve LLM interactions by validating Pydantic schemas before making API calls. This approach involves testing the schema with dummy data during development or at boot time, catching s…
-
AI agents can cut token waste by stripping tool schema cruft
Developers can significantly reduce token waste in AI agent tool schemas by removing unnecessary fields like "title", "$schema", and "additionalProperties". These fields, often comprising up to 20% of a schema's size, d…

AI Agent Converts Legacy Finite-Difference Code to Devito
Researchers have developed an AI agent framework designed to convert legacy finite-difference code into the Devito environment. This system utilizes Retrieval-Augmented Generation (RAG) and open-source Large Language Mo…
-
AI agent tool naming boosted accuracy from 71% to 94%
A software development team significantly improved their AI agent's tool-call accuracy by renaming its available functions. Previously, the agent made a costly error by misinterpreting a "cancel" tool as a full transact…
