Release Notes

0.2.45rc1 (2026-07-02)

Release candidate — install with pip install aixplain==0.2.45rc1. Not served by default pip install aixplain.

v2-agent: Agent.get() + save() no longer silently overwrites the agent's LLM with the default (GPT-5.4). On 0.2.43/0.2.44 the fetched agent never decoded the model field from the API response, so agent.llm fell back to DEFAULT_LLM and any subsequent save() persisted it — resetting the agent's configured LLM (#922).
- If you used save() on 0.2.43/0.2.44, verify your agents' LLM and re-pin once if needed: agent.llm = "<model_id>"; agent.save().
