LlamaIndex v0.14.24 adds Claude Sonnet 5 / Opus 5, Gemini 3.7 Flash, GPT-5.6, and multimodal AG-UI input

LlamaIndex 0.14.24 ships broad model allowlist updates (Claude Sonnet 5, Opus 5 with 1M context on Opus 4.6, GPT-5.6, Gemini 3.7 Flash as new default) across the anthropic, bedrock-converse, openai, and google-genai integrations. AG-UI protocol 0.4.0 now supports multimodal user input (images, audio, video, documents). Memory can accept any AsyncDBChatStore, LLMRerank gains async, and dozens of core bug fixes land for agents, ingestion, and retrieval.
