deepseek-chat-v3-0324deepseekDeepSeek V3, a 685B-parameter, mixture-of-experts model, is the latest iteration of the flagship chat model family from the DeepSeek team. It succeeds the [DeepSeek V3](/deepseek/deepseek-chat-v3) model and performs really well on a variety of tasks.Input:$0.18 / 1M tokensOutput:$0.72 / 1M tokensContext:163840 tokenstoolstexttext
gpt-4o-miniopenaiGPT-4o mini (o for omni) is a fast, affordable small model for focused tasks. It accepts both text and image inputs, and produces text outputs (including Structured Outputs). It is ideal for fine-tuning, and model outputs from a larger model like GPT-4o can be distilled to GPT-4o-mini to produce similar results at lower cost and latency.The knowledge cutoff for GPT-4o-mini models is October, 2023.Input:$0.15 / 1M tokensOutput:$0.6 / 1M tokensContext:128K tokenstoolstextimagetext- deepseek-chatdeepseekDeepSeek-Chat is an advanced conversational AI model designed to provide intelligentInput:$0.27 / 1M tokensOutput:$1.1 / 1M tokensContext:64K tokenstoolstexttext

glm-4.5z-aiGLM-4.5 is our latest flagship foundation model, purpose-built for agent-based applications. It leverages a Mixture-of-Experts (MoE) architecture and supports a context length of up to 128k tokens. GLM-4.5 delivers significantly enhanced capabilities in reasoning, code generation, and agent alignment. It supports a hybrid inference mode with two options, a "thinking mode" designed for complex reasoning and tool use, and a "non-thinking mode" optimized for instant responses. Users can control the reasoning behaviour with the `reasoning` `enabled` boolean.
