docs: document the reasoning-model gotcha in README - #6
Merged
Conversation
Several Nebius-hosted models (Kimi-K2.5, DeepSeek-V3.2, GLM-5, Qwen3 thinking variants) emit hidden reasoning tokens before producing visible output. Those tokens count against max_tokens. Empirically, a 64-token request to Kimi-K2.5 comes back with empty content because the entire budget is consumed by reasoning, but no error is raised and the response looks structurally fine. Adds a "Reasoning models" subsection under Configure that lists the known reasoning-style models, explains the implication for max_tokens budgets, and points users at GET /v1/models for verification.
