Claude Haiku 5.5 - access through LLMTR

Claude Haiku 5.5 is Anthropic's current Haiku model for high-volume, latency-sensitive work such as classification, routing, extraction, and sub-agent tasks. It offers a 1M context window, 128K max output, adaptive thinking, vision input, tool calling, and prompt caching. Effort is configurable from low through max and defaults to medium; `none` turns thinking off. Prompts over 100,000 tokens are billed at a higher rate for input, output, and cache. The last message must be a user message; assistant prefill is not accepted.
