Anthropic released Fable 5.2 and Mythos 5.2 today, with the llm-anthropic CLI plugin adding immediate support. Hands-on testing shows five reasoning levels from low to max, where xhigh produced the best SVG output while max exhausted 128,000 tokens on reasoning and failed to return an image, reproducing a known bug.
