Aug 1, 2025

August 2025 (2025-08) – Delivered a comprehensive Rate Limits Documentation Update for e2b-dev/E2B, consolidating API and sandbox limits across Hobby, Pro, and Enterprise. Implemented via three commits, including a Pro concurrency typo fix and a Hobby sandbox limit update (10 -> 20), providing clearer guidance, reducing misconfigurations, and accelerating onboarding and testing. Business impact includes improved developer experience, fewer support escalations related to rate limits, and stronger governance of plan-specific quotas.

May 2025 monthly summary for e2b-dev/E2B: Delivered an enhancement to the Hugging Face Serverless Inference API Quickstart by adding a dedicated section that demonstrates integration with the InferenceClient from huggingface_hub. The update includes a Python code example and a utility to extract Python code blocks from LLM responses, along with a practical use case illustrating runtime text processing (calculating the number of 'r' characters in 'strawberry'). This work strengthens developer onboarding, reduces integration friction, and demonstrates a scalable pattern for serverless inference in the quickstart guide. Related commit implements the change in (#726): af0773b74ddda5945e74956accacf9b968b4f8de.
