Lepton Ai

Lepton AI is a serverless AI platform providing OpenAI-compatible inference for open-source language models. For agents built on the OpenAI API format, Lepton's compatibility means switching to cost-competitive open-source models requires only an endpoint URL change. Lepton targets teams that want the simplicity of managed inference without the operational overhead of GPU clusters and the cost structure of proprietary model providers.

Authentication uses API tokens following the OpenAI Bearer token convention. The familiar auth pattern reduces integration effort for teams with existing OpenAI integrations. Teams should treat Lepton API tokens as billing-sensitive credentials — they authorize inference operations that consume credits.

Documentation is functional and covers the API with adequate depth. Teams primarily interested in the OpenAI-compatible inference surface will find the essential documentation present. Lepton's documentation reflects the platform's stage — clear for core use cases but less comprehensive than established providers for edge cases and advanced configuration.

The API follows the OpenAI chat completions format, enabling drop-in substitution for agents already using OpenAI-compatible clients. Model selection and parameters follow the same conventions as other OpenAI-compatible providers. Lepton also supports custom model deployments for teams with fine-tuned models they want to serve on managed infrastructure.

Reliability is appropriate for a serverless inference platform. Lepton is a newer entrant in the managed inference space; teams with strict uptime requirements should verify current SLA commitments and consider multi-provider fallback strategies for production workloads.
