  • Premium commercial pricing ($3.00 input / $15.00 output per 1M)
  • Smaller enterprise ecosystem than major cloud hyper-scalers

Editorial Assessment

A versatile frontier omnimodal model built from the ground up for rich media processing.

Best for: Multimodal video search, audio-visual QA, and cross-format media intelligence

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: Multimodal video search, audio-visual QA, and cross-format media intelligence. Assessment: A versatile frontier omnimodal model built from the ground up for rich media processing.
