Model family

Reka Flash

Reka Flash is a model family from Reka1 3, with 1 assessed release in this catalog. Licenses and availability are recorded for each release, not for the family; its releases use the Apache License 2.0.

Reka Flash is a line of Reka language models; this record covers its open-weight releases. Reka Flash 3 (March 2025) is a 21B-parameter reasoning model that Reka says was pretrained from scratch on publicly accessible and synthetic data, then instruction-tuned and trained with reinforcement learning; it was released as open weights under the Apache License 2.0. Reka Flash 3.1 (July 2025) updated it with further reinforcement learning aimed at coding and agentic tasks, and was released with a 3.5-bit quantized version and the Reka Quant quantization library.1 2 3 4Fact reviewed Oct 2, 2026

What it is useful for

Reka describes the open Flash models as suited to general chat, coding, instruction following, and function calling in low-latency or local deployments, and Flash 3.1 as a base for fine-tuning on agentic tasks.1 4Fact reviewed Oct 2, 2026

Organization context

Reka

Provenance and derivatives

Reka states that Reka Flash 3 was pretrained from scratch, and that Reka Flash 3.1 is an update to Reka Flash 3. Both are distributed in a Llama-compatible format so that libraries supporting Llama can run them; that is a file-format choice, not a statement that the weights derive from Llama.1 2 4

U.S. eligibility

Project eligibility rests on documented governing or maintaining entities, not on contributors.

Eligible · basis: U.S. headquarters

The Reka Flash models are developed and published by Reka AI, Inc., whose privacy policy states that it is headquartered in the United States and whose June 2026 announcement describes it as headquartered in San Francisco (see the Reka record). Each release is assessed on its own record.5 6 4
