v5.1.0: rate limits, refactored settings

Highlights

In-housed rate limits management

• Centers on a moving window algorithm with either a Redis or in-memory state
• Supports dynamically defined rates for different models or providers.
• New bundled configurations for different OpenAI rate limit tiers
• Accomplished using new third party dependencies coredis and limits

Refactored Settings to allow for increased flexibility

• Indexing
  • Indexes can use relative paths, enabling sharing across machines
  • Paper search now no longer rebuilds the index every invocation
  • Index parameter now are grouped in IndexSettings
    • This release begins a deprecation cycle for the original hyperparameters
  • Index builds now have a rich.Progress bar
• Parsing
  • Chunking and embedding can now be deferred to inference time
• Agents
  • Agents now have a max_timesteps parameter to upper-bound trajectory length
  • Default agent is now a simple tool calling agent (ToolSelector), instead of a deterministic sequence of tool calls ("fake" agent)

Several bug fixes centered on retry-able errors:

• Flaky Semantic Scholar and Crossref SSL errors and connection reset errors
• LLM completions and text embeddings
