Anthropic released Claude Sonnet 5.5 on 2026-09-28 at $2/$10 per million input/output tokens, unchanged from Sonnet 5. Its published benchmark table puts it near Opus 5.5 on several tasks, while its migration guide lists breaking changes for Sonnet 5 users.
The Model Context Protocol standardizes how AI hosts connect to servers that provide tools, resources and prompts, with separate transports and security responsibilities.
A practical map of speech recognition, language models, speech synthesis, direct speech-to-speech models, streaming, and the latency measurements that matter.
A vector database answers “what is closest in meaning to this?” instead of “which rows match?”. Here is the machinery: embeddings, distance, and why you never design the fields.
agentgateway 1.5 puts one Rust proxy and one policy language in front of LLM APIs, MCP tool servers and A2A agents. Its per-caller tool authorization is the real thing; its open-by-default settings are not production-ready.

An inside look at why AI systems switch between models — the cost-saving chooser everyone talks about, and the failover path that's where outages actually hide.
