deepreasoning
DeepReasoning is a Rust-based inference API that chains DeepSeek R1's reasoning traces with Anthropic Claude for combined problem-solving and code generation. It offers a unified chat interface and API with end-to-end streaming, requiring users to supply their own API keys for both services.

What deepreasoning is
High-performance Rust API that orchestrates dual-model inference: DeepSeek R1 for chain-of-thought reasoning, followed by Claude 3.5 Sonnet for synthesis and code generation. Supports streaming responses, configurable model parameters, and local key management via custom headers.

Best use cases
Implementation considerations
- Requires valid, active API keys for both DeepSeek and Anthropic; key rotation and expiration handling not documented.
- Rust 1.75+ is mandatory. Build and deployment assume Rust toolchain availability; Docker image support unclear from README.
- Configuration via config.toml or environment variables; no schema validation or defaults clearly specified.
- Streaming implementation uses server-sent events (SSE); clients must handle partial JSON and async frame boundaries.
- Pricing module mentioned in config but no usage tracking, cost attribution, or billing integration details provided.
When to avoid it — and what to weigh
- Latency-sensitive applications requiring sub-100ms responses — Sequential reasoning + generation introduces cumulative latency. Two model calls in series will be slower than single-model inference.
- Budget-constrained deployments with high query volume — Each request incurs costs for both DeepSeek and Anthropic APIs. Dual-model billing will be 2x higher than single-model alternatives.
- Fully offline or air-gapped environments — Requires active API connectivity to both DeepSeek and Anthropic. No local model weights or standalone inference capability documented.
- Need for model output guarantees or SLA compliance — Depends on third-party API availability and uptime. No SLA, fallback handling, or circuit-breaker patterns documented.
License & commercial use
Licensed under MIT (OSI-compliant, permissive). Grants freedom to use, modify, and distribute with minimal restrictions.
MIT license permits commercial use without restriction. However, commercial deployment requires valid API keys and paid accounts with both DeepSeek and Anthropic. The license covers the code; you are responsible for third-party service terms of service. The project itself is unaffiliated with Anthropic (explicitly disclaimed in README). Requires independent review of DeepSeek and Anthropic commercial agreements.

API keys transmitted via HTTP headers; authentication relies on header presence and external API validation. README claims 'end-to-end security' and 'no data storage or logging' but provides no audit trail, encryption, or verification mechanism. BYOK (Bring Your Own Keys) model transfers trust to client infrastructure. No documented rate-limiting, input validation, injection prevention, or vulnerability disclosure process. TLS enforcement not explicitly mentioned. Authenticate via header-only (no bearer token, session, or OAuth) increases surface for key exposure in logs or proxies.
Alternatives to consider
LangChain + LangSmith
Orchestrates multi-model workflows, includes observability, and abstracts provider APIs. Larger ecosystem but higher operational overhead.
Anthropic Prompt Caching + Claude alone
Single-vendor, simpler deployment, native reasoning/code capabilities. Avoids dual-model complexity and cost but forgoes R1's specialized reasoning.
OpenRouter or Together AI
Unified API across multiple models (DeepSeek, Claude, others) with built-in load balancing and billing. Less customization but reduced operational burden.
