Coding and code review
Generate, debug, and review code across languages, reading whole files or repos in a single prompt.

Agentic and multi-step workflows
Reliable tool-calling and instruction-following suit agent loops that plan, call tools, and iterate.

Complex reasoning
Extended reasoning improves reliability on multi-step math, logic, and technical analysis.

Long-document analysis
Summarize and extract from contracts, papers, and reports without aggressive chunking.

Use cases

Reka Flash 3 is documented as a good foundation for applications that require low latency or on-device deployment.

It is also described as powering Nexus, a platform for organizations to create and manage AI workers, with those workers able to browse the web, execute code, and analyze internal files such as documents, images, videos, and audio.

Another documented use case is general chat, coding, instruction following, and function calling.

It is also recommended for knowledge-related tasks when paired with web search, since the model is described as not the best choice for knowledge-intensive tasks on its own.

Capabilities

  • Function calling
  • Reasoning
  • Streaming
  • Structured outputs
  • Web search
