v3.0.0

Release Date: Jun 2026

elsai Model v2.0.0 — unified *Model provider API

New features

• Unified Model base class — all providers expose .invoke(), .stream(), and .stream_text()
• Agent integration — pass *Model instances directly to Agent(model=…)
• New providers — Mistral, Writer, Meta Llama API, llama.cpp, OpenAI Responses, SageMaker
• Optional extras — openai-responses, llamaapi, sagemaker, langchain

Breaking changes

• *Connector classes and GeminiService replaced by *Model classes
• Constructor shape: model_id, client_args, params instead of provider-specific connector kwargs
• Legacy connector API documented at v2.0 LLM Models

Migration

Legacy (v1.4.x)	v3
OpenAIConnector(model_name=…)	OpenAIModel(model_id=…, client_args=…)
BedrockConnector(aws_access_key=…)	BedrockModel(model_id=…, region_name=…)
GeminiService.generate_text(…)	GeminiModel.invoke(messages)

See LLM Models and Model Providers.
