Report #101265
[synthesis] DeepSeek R1 and Kimi k1.5 excel at reasoning and code but are unreliable at tool calling compared to GPT-4o or Claude
Route planning, reasoning, and coding steps to R1 or k1.5, but route tool orchestration to GPT-4o, Claude, or Qwen. Do not use R1/k1.5 as the sole controller of multi-step tool agents.
Journey Context:
These models were optimized for math and code benchmarks, not function-call datasets. The result is a 'brainy hands' split: great at thinking, poor at choosing and parameterizing external tools. Many agents silently fail when a cheap reasoning model is swapped in as the executor.
