Summary
AI summaryAdded first-class prompt caching options for OpenAI, xAI/Grok, and updated trace handling to preserve cache keys.
Full changelog
0.1.5 - 2026-06-28
Added
- Added a dedicated prompt-caching guide and runnable example covering stable
cache-key construction, provider-specific cache controls, and cache-hit
inspection across OpenAI, xAI/Grok, Anthropic, Moonshot/Kimi, Gemini, and
Z.ai. - Added first-class OpenAI Responses and Chat Completions
prompt_cache_keyand
prompt_cache_retentionmodel options, while keeping per-call overrides. - Added xAI/Grok cache routing support: Responses accepts
prompt_cache_key,
and Chat Completions acceptsx_grok_conv_id, which BeamWeaver sends as the
x-grok-conv-idheader.
Changed
- Model traces now preserve provider-specific invocation parameters from the
checked-in profile registry, including cache keys and cache-routing options,
while still omitting client configuration and secrets. - Redaction now keeps token counts and generation limits such as
max_output_tokens,budget_tokens, and*_token_countfields so cache and
usage telemetry remain inspectable.
Fixed
- OpenAI Responses
prompt_cache_keynow respects first-class model options
ahead ofmodel_kwargs, while per-call options continue to take precedence. - xAI requests now merge per-call headers with default headers and let per-call
x_grok_conv_idoverride the model-level conversation/cache routing header.
