Switch friction

Phi-4 14B -> Qwen3.6-35B-A3B
  • Provider overlap exists on OpenRouter; start route-level A/B tests there.
  • Qwen3.6-35B-A3B is $0.86/1M tokens higher on cheapest tracked output pricing, so quality gains need to justify the spend.
  • Check replacement coverage for Structured outputs before moving production traffic.
  • Qwen3.6-35B-A3B adds Vision, Multimodal, and Function calling in local capability data.

Deep dive

On shared benchmark coverage, Google-Proof Q&A has Phi-4 14B at 56.1 and Qwen3.6-35B-A3B at 86, with Qwen3.6-35B-A3B ahead by 29.9 points. The largest visible gap is 29.9 points on Google-Proof Q&A, which matters most when that benchmark mirrors your workload. Treat isolated benchmark wins as directional, because provider routing, prompt style, and tool access can move real application results.

The capability footprint differs most on vision: Qwen3.6-35B-A3B, multimodal input: Qwen3.6-35B-A3B, function calling: Qwen3.6-35B-A3B, tool use: Qwen3.6-35B-A3B, and structured outputs: Phi-4 14B. Both models share the core language-model surface, so the practical split is not just feature count. Use those differences to decide whether the page is about raw model quality, agentic coding support, multimodal ingestion, or predictable structured API behavior.

For cost, Phi-4 14B lists $0.07/1M input and $0.14/1M output tokens on the cheapest tracked provider, while Qwen3.6-35B-A3B lists $0.15/1M input and $1/1M output tokens on the cheapest tracked provider. A 70/30 input-output blend puts Phi-4 14B lower by about $0.32 per million blended tokens. Availability is 3 providers versus 2, so concentration risk also matters.

Choose Phi-4 14B when provider fit, lower input-token cost, and broader provider choice are central to the workload. Choose Qwen3.6-35B-A3B when coding workflow support and larger context windows are more important. For production, rerun your own prompts through the exact provider, region, and tool stack you plan to ship.

FAQ

Which has a larger context window, Phi-4 14B or Qwen3.6-35B-A3B?

Qwen3.6-35B-A3B supports 262k tokens, while Phi-4 14B supports 16k tokens. That gap matters most for long documents, large codebases, retrieval-heavy agents, and conversations where earlier context must remain visible. Use this as a quick comparison signal, then confirm the provider-specific limits before committing to production.

Which is cheaper, Phi-4 14B or Qwen3.6-35B-A3B?

Phi-4 14B is cheaper on tracked token pricing. Phi-4 14B costs $0.07/1M input and $0.14/1M output tokens. Qwen3.6-35B-A3B costs $0.15/1M input and $1/1M output tokens. Provider discounts or batch pricing can still change the final bill.

Is Phi-4 14B or Qwen3.6-35B-A3B open source?

Phi-4 14B is listed under MIT. Qwen3.6-35B-A3B is listed under Apache 2.0. License labels affect whether you can self-host, redistribute weights, or rely only on hosted APIs, so confirm the upstream license before deployment.
