v0.21.1
Chatlas 0.21.1 improves compatibility with the OpenAI 3 SDK and fixes citation and token-cost edge cases.
What is fixed
- OpenAI-based providers now support native
httpx2clients from the OpenAI 3 SDK. Legacyhttpxclients remain supported at runtime during migration. (#387) - Anthropic citations backed by
document_indexnow resolve to source URLs correctly, including when prior turns contain document-shaped content. (#382) - Token cost lookups now handle output-only models and ellmer's versioned pricing-data format. (#382)
Custom provider compatibility
Custom Provider implementations must accept a turns keyword argument on .stream_content(), .stream_turn(), and .value_turn() so response references can be resolved against the complete request history.
