Reka AI 2026: Multimodal API & Research Agent

Reka AI is a US AI lab offering one OpenAI-compatible endpoint for text, image, video and audio understanding. ⚠️ Unlike stacks that combine separate vision, transcription and chat products, Reka Core and Flash accept multiple modalities through the same chat-completions surface. This review covers models, verified August 2026 pricing, integration, Research, regional access, competitors and practical limits.

🌍 Quick take: Reka is strongest for teams consolidating multimodal workloads and cited web research. There is no public permanent free tier, and mainland China access may require proxying.

💰 Pricing

Token rates are USD per million tokens; media units stack on top. Reka is pay-as-you-go from the first production request.

🔌 OpenAI Python SDK

from openai import OpenAI
client = OpenAI(base_url="https://api.reka.ai/v1", api_key="YOUR_REKA_API_KEY")
response = client.chat.completions.create(
    model="reka-flash",
    messages=[{"role": "user", "content": "Explain this image"}]
)
print(response.choices[0].message.content)

The same base URL works with OpenAI-compatible framework adapters. Tool calling, JSON mode and SSE streaming follow familiar chat-completions conventions, reducing migration work to a model-name and credential change.

🧠 Research agent

reka-flash-research plans sub-questions, runs web searches and synthesizes an answer with citations. Standard costs $25 per 1,000 requests, parallel-low $35, and parallel-high $60, plus consumed tokens. It fits due diligence, fact finding and market scans; casual chat should stay on Edge or Flash.

curl https://api.reka.ai/v1/chat/completions  -H "Authorization: Bearer YOUR_REKA_API_KEY"  -H "Content-Type: application/json"  -d '{"model":"reka-flash-research","messages":[{"role":"user","content":"Summarize recent EU AI Act enforcement with citations."}]}'

🌐 Regional availability

Reka publishes no mainland China endpoint. Direct CN routing is not guaranteed, so production teams should test a stable Hong Kong or Singapore gateway and monitor failures. Domestic alternatives such as Qwen, GLM, DeepSeek and Kimi offer similar OpenAI-compatible surfaces with lower in-region latency. Do not assume a fixed cross-border latency number.

⚠️ Limitations

  • No permanent public free tier.
  • No published mainland China region.
  • A thinner community and integration ecosystem than incumbents.
  • Parallel-high Research can become expensive without quotas.
  • Public enterprise compliance documentation is less extensive; confirm SOC 2, HIPAA and data-retention terms contractually.

🎯 Verdict

Choose Reka when one API and one invoice must cover text, image, video, audio and optional cited research. Edge is especially compelling for inexpensive routing. Skip it when a free tier, mainland deployment, the broadest third-party ecosystem or documented compliance packages are mandatory.
