Reka Core

Reka AI's multimodal foundation model that natively processes text, images, video, and audio (128K context). Founded by ex-DeepMind / Google / Meta researchers, Reka Core was originally pitched as a GPT-4V / Claude 3 Opus / Gemini Ultra rival. The company has since extended the stack with Reka Flash 3 (open-weights, 2025) and Reka Nexus (a multi-agent 'AI workforce' product). Reka Core remains API-only as the closed flagship; no verified 2026 successor to Core itself was found in this audit, though the surrounding product line has evolved.

Reka Core, frontier-class multimodal LLM announced 15 Apr 2024; 128K context. Proprietary: API/on-prem/on-device; no open weights. Instruction/multimodal-chat model. Verified live: launch page confirms API/on-prem/on-device availability and the MMMU/Claude-3-Opus claims. NOTE: '~5T tokens / 32 languages / from scratch' details are NOT on the cited launch page (they originate in Reka's separate technical report); verify against that source if retained. >12mo old; scored best-effort and flagged stale.
