Hy4 Preview is Tencent Hunyuan's open-weight mixture-of-experts flagship (770B total parameters, 49B active, Apache 2.0 license, 1M-token context), released August 28, 2026 as a preview ahead of a later official release. It targets coding agents, complex tool-use workflows, and productivity tasks like office work, game development, and scientific research rather than general chat.
Claude Haiku 4.5 is Anthropic's fast, affordable small model in the Claude 4 generation, balancing strong instruction-following and coding ability with low latency. It is designed for high-throughput agentic and chat applications where speed and cost efficiency are priorities.
