Compare Reka Core
Frequently Asked Questions about Reka Core
How much does the Reka Core API cost per 1M tokens?+
Reka Core by Reka is priced at $3 per 1M input tokens and $15 per 1M output tokens. With prompt caching enabled, cached input tokens cost $0.3 per 1M tokens, and asynchronous Batch API requests receive a 50% discount.
Should I use a $20/month subscription or the Reka Core pay-as-you-go API?+
A flat $20/month consumer subscription is predictable for daily interactive chat and manual coding. However, if you are building software, running automated workflows, or sending low-to-moderate volume with prompt caching enabled, the pay-as-you-go API is typically far more cost-effective and offers higher rate limits without manual UI caps.
How many words and pages fit in Reka Core's context window?+
Reka Core features a 128K tokens context window, which equals approximately 96,000 English words or ~256 standard single-spaced pages in a single prompt. Its maximum output generation per turn is 8,192 tokens.
Can I run Reka Core locally on my own GPU (Open Weights)?+
No, Reka Core is a proprietary closed-weights model hosted by Reka. It cannot be downloaded for local GPU execution and must be accessed via Reka's official API or cloud platform.
Does Reka train on data sent to the Reka Core API, and is commercial use allowed?+
API payloads are excluded from model training by default. License tier: Proprietary Commercial API (Reka Terms). Full commercial ownership of generated outputs. Supported deployment channels include: Reka Cloud API & Enterprise Endpoints.
How does Reka Core perform on coding and reasoning benchmarks?+
Reka Core achieves a composite Intelligence Index of 77/100, scoring N/A% on SWE-bench Verified, N/A% on GPQA Diamond, 75% on MMLU-Pro, and 1270 pts on Chatbot Arena Elo.
What is Reka Core best used for?+
Reka Core is best suited for: Sangat cocok untuk pemahaman multimodal asli (teks & visual) serta analisis dokumen kompleks, sistem RAG perusahaan, dan integrasi API skala produksi.. Assessment: Memadukan skor kecerdasan 77/100, konteks 128K, dan kecepatan 75 tok/dtk, Reka Core merupakan pilihan yang sangat andal dalam ekosistem Reka.
AI Glossary & Architecture Concepts
View full glossary →Key machine learning concepts and benchmarks relevant to Reka Core:
The basic unit of text that a language model processes, typically representing about 3 to 4 English characters or roughly 0.75 words. For example, the sentence "Artificial intelligence is fast" breaks down into about 5 tokens.
A standardized evaluation suite used to objectively measure and rank an AI model's capabilities across specific tasks — such as SWE-bench Verified for software engineering, AIME for competitive math, or MMLU for general knowledge.
The maximum number of tokens a model can consider at once — both the input it reads and the output it writes. A 1,000,000-token context window can hold roughly 750,000 English words in a single request.
An AI model trained via reinforcement learning to spend dynamic compute thinking through complex logic, math, and architectural problems before outputting a solution. Examples include OpenAI o1, o3, and DeepSeek R1.
A step-by-step reasoning technique where an AI model generates intermediate problem-solving thoughts before arriving at a final answer. Native reasoning models like OpenAI o3 and DeepSeek R1 use CoT to solve complex math and coding challenges.
The ability of a language model to recognize when an external capability is needed and output structured JSON arguments to invoke external APIs, databases, or terminal commands. The runtime executes the tool and passes results back to the model.
Benchmark scores, token prices, and rate limits evolve rapidly as AI labs release model updates. Always verify current specifications and pricing on the official provider documentation.
