v2026.46.2

Headline

• Container backends are now supported! Learn more: https://youtu.be/zfFuFRdyWgg
• Adds the Halogen container backend and 5 containers from Strix Halo Toolboxes: Gufo, strix-llama.cpp, nathanw, rocmfpx, and DwarfStar4.
• Benchmark results can now be submitted from lemonade bench to the public leaderboard with a single --submit flag, and a claim link lets others verify your setup.
• New classification and decision-model capabilities: zero-shot text classification via POST /v1/classify with a labels parameter, and SystemOne decision models for typed, image-based, or score-based questions.
• CUDA support added to TheNoise image generation engine.

Breaking Changes

• The native backend for DwarfStar4 has been replaced by the container backend.
• image_defaults and audio_defaults are no longer returned in the /models API response; their values are now nested under recipe_options, so clients reading the old keys will find them absent.
• A new user_configurable boolean flag on backend descriptor options may expose technical knobs such as soft_pixel_cap, pcm_sample_rate, and pcm_channels to users — filter on this flag to hide internal settings.
• FLM v1.0.11 returns max_tokens exactly as requested rather than max_tokens+1, so chat completions that relied on the extra token will now stop one token early.
• FLM v1.0.11 streams token usage counts only when stream_options.include_usage is set; without it, the /api/v1/stats endpoint records no token counts or throughput for FLM streams.
• FLM v1.0.11 returns 400 for previously-accepted invalid fields including invalid tool_choice, forced tool calls on small Qwen3 models (up to 1.7B), conversation history on *-flash models, and requests with no messages or prompt.
