Log10

Log10 is an LLMOps platform that provides REST API and SDK capabilities for capturing, logging, and managing LLM completions across major providers such as OpenAI, Anthropic, Google Gemini, Mistral, and Meta Llama. The platform enables engineering teams to debug prompt chains, run automated evaluations, collect human and AI-generated feedback, and benchmark model outputs at scale. Log10 supports session-based tracing, tag-based filtering, and cost tracking to help organizations optimize accuracy and operational efficiency of their generative AI applications. Developers can integrate via a Python SDK, TypeScript SDK, or directly via the REST and GraphQL API using an API token and organization ID.

Log10 publishes 5 APIs on the APIs.io network, including Feedback API, Completions API, and 3 more. Tagged areas include LLM, Logging, Observability, Evaluation, and Feedback.

The Log10 catalog on APIs.io includes 1 JSON-LD context and 1 Spectral governance ruleset.

Log10’s developer surface includes authentication, documentation, engineering blog, pricing, and 18 more developer resources.
