MARS5 by Camb.ai

Microsoft’s new reasoning model, trained from scratch and optimized for code. It rivals the best models on SWE-Bench Pro and AIME 2025, while remaining medium-sized and computationally efficient

Access GPT-5.4, Claude Opus 4.6, Gemini 3.1, and over 100 large language models (LLMs) through a single API key compatible with OpenAI, Claude, and Gemini. Enjoy ultra-fast global routing (300 ms), shared billing for teams, and support for OpenClaw

Run a 35-billion-parameter MoE model with only 3 billion parameters actually activated, while achieving coding, vision, and reasoning performance on par with much larger models. Optimized for agentic coding, multimodal perception, and very long contexts (up to over a million tokens)

Take advantage of enhanced audio and visual understanding to create comprehensive multimodal applications, ranging from image analysis to audio interpretation. The open-source E2B and E4B models offer optimal memory capacity and computational efficiency. Perfect for inference on devices with limited resources
