Apache-2.0 text model with 501B total and 23B active parameters; ships BF16, FP8 and NVFP4 weights.
Meta: Muse Spark Open
OpenRouter lists a 1,048,576-token context and up to 943,718 output tokens for this open-weight model aimed at agentic coding.
Nemotron 3.5 Super VL
120B/12B-active Mamba-2 hybrid with a vision encoder; native speculative decoding and switchable thinking.
Google: Gemini 4 Argon
Long decode can use the unified 1M-token budget for output; reads video, audio and PDFs, with implicit-only caching.
OpenAI: GPT-6.1 Sol
Requires Responses API for tools; offers Ultrafast inference with US or EU data residency.
Anthropic: Claude Sonnet 5.5
Tuned for quick iteration on scoped fixes and documents; Anthropic favors Opus 5.5 for open-ended work needing sustained judgment.
AssemblyAI: Universal-3.5 Pro
Universal-3.5 Pro is AssemblyAI's speech-to-text model served through its Sync API, returning a complete transcript with word-level timestamps in a single synchronous response for audio up to 20 minutes. It...
Anthropic: Claude Opus 5.5
Always-on adaptive thinking defaults to medium effort; built for sustained work across large codebases and professional documents.
OpenAI: GPT-6 Luna
Can turn reasoning off for high-volume requests; Chat Completions tool calls require reasoning_effort=none.
Xiaomi: MiMo-V2.6-Pro
MiMo-V2.6-Pro is the flagship foundation model developed by Xiaomi. Built at a scale of over 1T parameters, it is designed to push the ceiling of capability for the most demanding...
Step-5-Preview
600B total and 27B active parameters; accepts images and video, with FP8 and BF16 weights for deployment.
DeepSeek: DeepSeek V4.1 Flash
Causal encoder-decoder activates 8B parameters for input and 16B for output, reducing the compute needed for long inputs.
K2 Horizon 375B A23B
OpenAI: GPT-6 Astra
Accepts mid-turn steering and async tool calls, so agents can take new instructions while other tools are still running.
Anthropic: Claude Fable 5.1
Beta controls change effort per message without invalidating the prompt cache and report progress between tool calls.
