DeepSeek thinks, Claude answers: a two-model API proxy

What it does

DeepReasoning is a Rust API and chat interface that calls DeepSeek R1 to generate a Chain-of-Thought reasoning trace, then passes that context to Anthropic Claude to produce the final answer. The goal is to combine R1’s self-correcting reasoning with Claude’s coding and conversational skills in one request. You can self-host it or use the managed BYOK service.

The interesting bit

Rather than picking one model, the project uses R1 as a reasoning preprocessor for Claude and streams both steps back as a single response. It is essentially sophisticated glue code—high-performance Rust glue, but glue nonetheless—with a web UI and per-request overrides for each backend API.

Key highlights

• Chains DeepSeek R1 and Anthropic Claude into a single streaming API response
• BYOK architecture: you supply both API keys, and the README states no data is stored or logged
• Per-request deepseek_config and anthropic_config objects let you tweak headers and body parameters for each provider
• Rust backend with an included chat frontend
• Open source under MIT license

Caveats

• The README advertises “Zero Latency” for a service that inherently waits on two sequential remote API calls
• Requires active API keys for both DeepSeek and Anthropic to function
• Repository links and branding are inconsistent between the winfunc and getasterisk namespaces visible in the README

Verdict

Useful if you want Claude’s outputs guided by R1’s reasoning traces and are comfortable supplying keys for both services. Not for anyone seeking a local, self-contained model; this is strictly an API orchestrator.
