Key Takeaways
- DeepSeek Wins When:
- Precision is essential (e.g., unsafe Rust, quantum gates, type-level Haskell).
- Optimization issues (SIMD, compile-time macros, in-place meeting).
- Area of interest toolchains are concerned (WASI, Neo4j Cypher, Q#).
- ChatGPT Wins When:
- Explainability is required (e.g., Grover’s algorithm, impasse debugging).
- Artistic regex/GA options are required (evolving case-sensitive patterns).
- Cross-domain reasoning (e.g., Unicode + meeting, graph concept + social networks).
Shocking Edge Instances
- Quantum Computing:
- DeepSeek generated a working Q# oracle for the NAND SAT drawback however missed a phase-handling edge case.
- ChatGPT’s oracle logic was flawed however offered clearer feedback for debugging.
- Metaprogramming:
- DeepSeek’s Elixir macro dynamically generated
f0
–f99
features however hardcoded the hash algorithm. - ChatGPT used
apply/3
as a fallback, violating the immediate’s constraints.
- DeepSeek’s Elixir macro dynamically generated
- Concurrency:
- DeepSeek’s
sync.Cond
refactor averted deadlocks however launched a refined hunger bug. - ChatGPT’s resolution retained deadlocks however defined the round dependency visually.
- DeepSeek’s
Closing Verdict
- DeepSeek wins 6/11 prompts (esoteric languages, quantum, concurrency, Haskell, WASM, Scala).
- ChatGPT wins 5/11 prompts (GA, regex, error dealing with, graph DBs, recursion scheme explanations).
Why It’s Shocking:
- DeepSeek outperformed expectations in low-level/compile-time duties however struggled with person intent parsing (e.g., ignoring “no case modifiers” in regex GA).
- ChatGPT misplaced on precision however excelled in educating complicated ideas (e.g., histomorphisms, Grover’s algorithm).
When to Use Which Mannequin
- Select DeepSeek for:
- Area of interest languages (Zig, Q#), unsafe code, or type-level programming.
- Efficiency-critical code (SIMD, in-place meeting).
- Select ChatGPT for:
- Studying/explaining ideas (recursion schemes, deadlocks).
- Artistic regex/GA design or cross-toolchain tasks (Deno + WASM).
