Changelog

Source: NEWS.md

EndpointR 0.2

• error message and status propagation improvement. Now writes .error, .error_msg (standardised across package), and .status. Main change is preventing httr2 eating the errors before we can deal with them
• adds parquet writing to oai_complete_df and oai_embed_df
• adds chunks func to oai_embed, and re-writes all batch -> chunk logic
• implements the Anthropic messages API with structured outputs (via BETA)
• adds ant_complete_df() and ant_complete_chunks() for batch/chunked processing with the Anthropic API, with parquet writing and metadata tracking
• metadata tracking now includes schema and system_prompt for both OpenAI and Anthropic chunked processing functions
• bug fix: S7 schema objects now correctly serialised to metadata.json (previously caused “No method asJSON S3 class: S7_object” error)
• adds spelling test, sets language to en-GB in DESCRIPTION

EndpointR 0.1.2

• File writing improvements: hf_embed_df() and hf_classify_df() now write intermediate results as .parquet files to output_dir directories, similar to improvements in 0.1.1 for OpenAI functions

• Parameter changes: Moved from batch_size to chunk_size argument across hf_embed_df(), hf_classify_df(), and oai_complete_df() for consistency

• New chunking functions: Introduced hf_embed_chunks() and hf_classify_chunks() for more efficient batch processing with better error handling

• Dependency update: Package now depends on arrow for faster .parquet file writing and reading

• Metadata tracking: Hugging Face functions that write to files (hf_embed_df(), hf_classify_df(), hf_embed_chunks(), hf_classify_chunks()) now write metadata.json to output directories containing:

  • Endpoint URL and API key name used
  • Processing parameters (chunk_size, concurrent_requests, timeout, max_retries)
  • Inference parameters (truncate, max_length)
  • Timestamp and row counts
  • Useful for debugging, reproducibility, and tracking which models/endpoints were used

• max_length parameter: Added max_length parameter to hf_classify_df() and hf_classify_chunks() for text truncation control. Note: hf_embed_df() handles truncation automatically via endpoint configuration (set AUTO_TRUNCATE in endpoint settings)

• New utility functions:

  • hf_get_model_max_length() - Retrieve maximum token length for a Hugging Face model
  • hf_get_endpoint_info() - Retrieve detailed information about a Hugging Face Inference Endpoint

• Improved reporting: Chunked/batch processing functions now report total successes and failures at completion

EndpointR 0.1.1

• oai_complete_chunks() function to better support for chunking/batching in oai_complete_df()
• oai_complete_df() now writes to a file to mitigate the chance of completely lost data

EndpointR 0.1.0

Initial BETA release, ships with:

• Support for embeddings and classification with Hugging Face Inference API & Dedicated Inference Endpoints
• Support for text completion using OpenAI models via the Chat Completions API
• Support for embeddings with the OpenAI Embeddings API
• Structured outputs via JSON schemas and validators
