VerifiedReka Flash 3 handles long text contexts up to 64k tokens efficiently.
About Reka Flash 3
Reka Flash 3 follows a closed-source design that keeps its architecture and weights proprietary. This structure supports a 65536-token context window while restricting direct access to model internals. The text-only modality focuses processing power on language tasks without image or audio support.
Its primary strengths lie in sustained coherence across lengthy documents and conversations. Organizations use it for content creation, summarization, and technical writing where large context retention matters. Typical deployments involve API access for enterprise applications requiring consistent text output.

import OpenAI from "openai";
const client = new OpenAI({
baseURL: "https://openrouter.ai/api/v1",
apiKey: process.env.OPENROUTER_API_KEY,
});
const completion = await client.chat.completions.create({
model: "rekaai/reka-flash-3",
messages: [{ role: "user", content: "Hello!" }],
});
console.log(completion.choices[0].message.content);Model slug: rekaai/reka-flash-3
