256k-context

Kwaipilot has released KAT-Coder-Pro V2.5, a coding-focused language model with a 256,000-token context window. The model is priced at $0.74 per million input tokens and $2.96 per million output tokens, available through OpenRouter.

Mistral AI has released Mistral Small 4, a 119B total parameter mixture-of-experts model with 256K context window and native multimodal capabilities. The model uses 128 experts with 4 active per token (6B active parameters) and is released under the Apache 2.0 license, marking Mistral's first unified model combining reasoning, multimodal, and coding capabilities.

Tencent has released Hy3-preview, a 295-billion-parameter Mixture-of-Experts model with 21 billion active parameters and a 256K context window. The model scores 76.28% on MATH and 34.86% on LiveCodeBench-v6, with particularly strong performance on coding agent tasks.

Google DeepMind released Gemma 4, an open-weights multimodal model family in four sizes (2.3B to 31B parameters) with context windows up to 256K tokens. All models support text and image input, with audio native to E2B and E4B variants. The Gemma 4 31B dense model scores 85.2% on MMLU Pro, 89.2% on AIME 2026, and 80.0% on LiveCodeBench—significant improvements over Gemma 3.

Google DeepMind released Gemma 4, an open-weights multimodal model family in four sizes (E2B, E4B, 26B A4B, 31B) with context windows up to 256K tokens and native reasoning capabilities. The 26B A4B variant uses Mixture-of-Experts architecture with 3.8B active parameters for efficient inference. All models support text, image input and handle 140+ languages with Apache 2.0 licensing.

Google DeepMind has released Gemma 4 31B, a 30.7-billion-parameter multimodal model supporting text and image input. The model features a 262,144-token context window, configurable thinking/reasoning mode, native function calling, and multilingual support across 140+ languages under Apache 2.0 license.

Kwaipilot released KAT-Coder-Pro V2, the latest model in its KAT-Coder series, on March 27, 2026. The model features a 256,000-token context window and is priced at $0.30 per million input tokens and $1.20 per million output tokens. It targets enterprise-grade software engineering with focus on multi-system coordination and web aesthetics generation.

NVIDIA Nemotron 3 Super, a hybrid Mixture of Experts model with 120B parameters and 12B active parameters, is now available as a fully managed model on Amazon Bedrock. The model supports up to 256K token context length and claims 5x higher throughput efficiency over the previous Nemotron Super and 2x higher accuracy on reasoning tasks.
