Devstral 2 2512 vs Grok 3
Grok 3 is the practical winner for most common enterprise and analysis tasks — it wins 6 of 12 benchmarks in our testing (strategic_analysis, faithfulness, classification, safety_calibration, persona_consistency, agentic_planning). Devstral 2 2512 wins key creative and compression tasks (constrained_rewriting and creative_problem_solving) and is dramatically cheaper, so choose it when token cost or 256K context matters.

Benchmark Analysis
Across our 12-test suite, Grok 3 wins a majority: strategic_analysis 5 vs 4 (Grok ranks tied for 1st of 54; Devstral rank 27), faithfulness 5 vs 4 (Grok tied for 1st of 55; Devstral rank 34), classification 4 vs 3 (Grok tied for 1st of 53; Devstral rank 31), safety_calibration 2 vs 1 (Grok rank 12 of 55; Devstral rank 32), persona_consistency 5 vs 4 (Grok tied for 1st of 53; Devstral rank 38), and agentic_planning 5 vs 4 (Grok tied for 1st of 54; Devstral rank 16). Devstral 2 2512 wins constrained_rewriting 5 vs 3 (Devstral tied for 1st of 53) and creative_problem_solving 4 vs 3 (Devstral rank 9 vs Grok rank 30). Four tests tie: structured_output (both 5, tied for 1st), tool_calling (both 4, rank 18), long_context (both 5, tied for 1st), and multilingual (both 5, tied for 1st). Practical meaning: Grok 3 is stronger where nuanced tradeoff reasoning, staying faithful to sources, classification/routing, and agentic planning matter — useful for data extraction, reliable multi-step planning, and safety-sensitive enterprise flows. Devstral is superior where hard character compression and idea-generation matter (best-in-class constrained_rewriting and stronger creative outputs) and also offers a larger context window (262,144 vs Grok's 131,072) for extremely long prompts or retrieval contexts.
Pricing Analysis
Costs are per mTok (per 1,000 tokens). Devstral 2 2512 charges $0.40 input / $2.00 output per mTok; Grok 3 charges $3.00 input / $15.00 output per mTok. That means per 1M tokens (1,000 mTok): Devstral = $400 (all input) to $2,000 (all output); Grok = $3,000 to $15,000. At a 50/50 input/output split per 1M tokens: Devstral ≈ $1,200; Grok ≈ $9,000. Multiply by 10 for 10M (Devstral $12k vs Grok $90k) or 100 for 100M (Devstral $120k vs Grok $900k). Who should care: startups, high-volume APIs, and apps with continuous inference should favor Devstral for cost reasons; enterprises prioritizing highest scores on strategic analysis, faithfulness, and safety may accept Grok's ~8x–9x higher bill for equivalent usage patterns.
Real-World Cost Comparison
Bottom Line
Choose Devstral 2 2512 if you need a 256K context window, best-in-class constrained rewriting (score 5 in our tests), stronger creative problem outputs (4 vs Grok's 3), or you must minimize token costs (Devstral input/output $0.40/$2.00 vs Grok $3.00/$15.00 per mTok). Choose Grok 3 if your priority is strategic analysis, faithfulness, classification, safety calibration, persona consistency, or agentic planning (Grok wins those six benchmarks in our testing and ranks tied for 1st in several). If you balance budget and accuracy, run a small pilot: Devstral cuts bills by ~87% relative to Grok but concedes several high-level reasoning and safety scores.
