List of Reka AI Models
Reka Edge
rekaai/reka-edge
Reka Edge is a 7B multimodal vision-language model that processes text, image, and video inputs with industry-leading performance in its size class for visual reasoning, object detection, and agentic tool-use. It features a ConvNeXt V2 vision encoder that extracts only 64 tokens per image tile, enabling exceptionally fast and low-latency inference ideal for real-time applications like robotics, automotive, and augmented reality. It demonstrates frontier-level tool-calling abilities and strong temporal video reasoning, outperforming comparable models on benchmarks like MLVU, MMVU, and RefCOCO.
ChatReka Flash 3
rekaai/reka-flash-3
Reka Flash 3 is a 21-billion-parameter reasoning model developed by Reka AI, designed as a compact but capable general-purpose LLM. It excels at chat, coding, instruction following, and function calling. The model uses chain-of-thought reasoning via explicit thinking tags, and supports a "budget forcing" mechanism that lets you cap reasoning steps to control latency. It offers a 130K-token context window and is text-only (no image input). Reka AI positions it as competitive with OpenAI's o1-mini while being significantly smaller. It scores 65.0 on MMLU-Pro — modest for knowledge-heavy tasks, so pairing it with search or retrieval is recommended. It's primarily English-focused. Priced at $0.20 per million input tokens and $0.80 per million output tokens via the Reka API, it's a cost-effective option for developers who need solid reasoning at low cost.
