Summary: In our 12-test suite DeepSeek V3.2 wins 7 tests, Ministral 3 14B 2512 wins 2, and 3 tie. Detailed walk-through (score shown as {DeepSeek / Ministral}, rank context from our testing):

• structured_output: 5 / 4 — DeepSeek wins; tied for 1st (DeepSeek display: "tied for 1st with 24 other models out of 54 tested"). Practical meaning: DeepSeek is more reliable for strict JSON/schema outputs and integrations.

• strategic_analysis: 5 / 4 — DeepSeek wins; DeepSeek "tied for 1st with 25 other models out of 54 tested", Ministral rank 27 of 54. Practical: DeepSeek better at nuanced tradeoffs and number-backed reasoning.

• faithfulness: 5 / 4 — DeepSeek wins; DeepSeek tied for 1st (rank 1 of 55), Ministral rank 34 of 55. Practical: DeepSeek sticks to source material more consistently in our tests.

• long_context: 5 / 4 — DeepSeek wins; DeepSeek tied for 1st with 36 others (out of 55), Ministral rank 38 of 55. Practical: DeepSeek is stronger when retrieving/working with 30K+ token contexts.

• safety_calibration: 2 / 1 — DeepSeek wins; DeepSeek rank 12 of 55 vs Ministral rank 32 of 55. Practical: DeepSeek refused harmful prompts more appropriately while permitting legitimate requests more often in our safety tests.

• agentic_planning: 5 / 3 — DeepSeek wins; DeepSeek tied for 1st, Ministral rank 42 of 54. Practical: DeepSeek is better at goal decomposition and recovery in multi-step planning tests.

• multilingual: 5 / 4 — DeepSeek wins; DeepSeek tied for 1st, Ministral rank 36 of 55. Practical: DeepSeek produced higher-quality non-English outputs in our tests.

• tool_calling: 3 / 4 — Ministral wins; Ministral rank 18 of 54 vs DeepSeek rank 47 of 54. Practical: Ministral handled function selection, argument accuracy and sequencing better in our tool-calling scenarios.

• classification: 3 / 4 — Ministral wins; Ministral tied for 1st with 29 others (out of 53), DeepSeek rank 31 of 53. Practical: Ministral is more reliable for routing/categorization tasks in our evaluation.

• constrained_rewriting: 4 / 4 — tie; both rank 6 of 53. Practical: both handle tight character-limited rewrites equally.

• creative_problem_solving: 4 / 4 — tie; both rank 9 of 54. Practical: similar at generating non-obvious, feasible ideas.

• persona_consistency: 5 / 5 — tie; both tied for 1st. Practical: both maintain character and resist injection comparably.

Interpretation: DeepSeek's wins concentrate on long-context, structured output, faithfulness, strategic/agentic tasks — these are the behaviors developers rely on for retrieval-augmented generation, multi-step agents, and strict-output integration. Ministral's wins are concentrated on tool_calling and classification, and it also offers text+image->text modality, which matters when you need multimodal input. The two ties show parity on constrained rewriting, creative problem solving, and persona consistency.

Pricing per mTok (as listed): DeepSeek V3.2 input $0.26 / output $0.38; Ministral 3 14B 2512 input $0.20 / output $0.20. Using mTok = 1,000 tokens, cost examples: for 1,000,000 tokens (1M) — DeepSeek input-only $260, output-only $380, 50/50 split $320; Ministral input-only $200, output-only $200, 50/50 split $200. For 10M tokens multiply those figures by 10 (DeepSeek 50/50 = $3,200; Ministral 50/50 = $2,000). For 100M tokens multiply by 100 (DeepSeek 50/50 = $32,000; Ministral 50/50 = $20,000). The price ratio in the payload is 1.9x: DeepSeek is roughly 1.9× costlier overall. Who should care: startups and high-volume apps where tokens exceed millions/month will see tangible savings with Ministral (savings of $120 / 1M tokens at a 50/50 split, scaling to $12,000 at 100M). Teams prioritizing higher-scoring behavior on long-context, structured output, faithfulness, and agentic planning should weigh that against the ~1.9× price gap.

Choose DeepSeek V3.2 if you need: long-context retrieval (5/5), strict structured output compliance (5/5), high faithfulness (5/5), strategic analysis (5/5), or stronger agentic planning — in our testing it wins 7 of 12 benchmarks and ranks tied for 1st on multiple core developer tasks. Choose Ministral 3 14B 2512 if you need: lower cost (input/output $0.20), stronger tool-calling (4/5) and classification (4/5), or text+image->text inputs — it’s the better value and outperforms DeepSeek on function selection and routing while tying on persona consistency and creative problem solving.
