All prices per 1M tokens, Mistral official API (La Plateforme), April 2026:
| Model | Input | Output | Context | Best For |
|---|---|---|---|---|
| Large 3 | $2.00 | $6.00 | 128K | Flagship — coding, reasoning |
| Medium 3 | $0.40 | $2.00 | 128K | Balanced production |
| Small 3.1 | $0.20 | $0.60 | 128K | High-volume, cost-sensitive |
| Ministral 8B | $0.10 | $0.10 | 128K | Cheapest — classification, extraction |
| Codestral | $0.30 | $0.90 | 256K | Code generation specialist |
The headline: Large 3 output at $6/M is the cheapest flagship-tier output price in the market. Every other premium model charges $12-25/M.
Mistral's Output Price Advantage: Why It Matters
At 100M output tokens/month a content pipeline costs $600 on Mistral Large 3 vs $1,500 on GPT-5.4 or Claude Sonnet — a $900/month savings on output alone. Most API pricing discussions focus on input tokens. But for output-heavy workloads — content generation, code writing, detailed explanations — output cost dominates your bill.
Output price comparison across flagship models:
| Model | Output/M | Cost for 10M output tokens |
|---|---|---|
| DeepSeek V4 | $0.50 | $5 |
| Mistral Large 3 | $6.00 | $60 |
| Gemini 3.1 Pro | $12.00 | $120 |
| GPT-5.4 | $15.00 | $150 |
| Claude Sonnet 4.6 | $15.00 | $150 |
| Claude Opus 4.6 | $25.00 | $250 |
Mistral Large 3 is the second cheapest on output after DeepSeek — while being a competitive premium model with strong reasoning and coding capabilities.
When output costs dominate:
- Content generation (articles, summaries, reports) — typically 1:3 input/output ratio
- Code generation — often 1:2 or higher
- Detailed analysis and explanations
- Any task where you ask for long, structured responses
For a content pipeline generating 100M output tokens/month:
- Mistral Large 3: $600
- GPT-5.4: $1,500 (+150%)
- Claude Sonnet: $1,500 (+150%)
Mistral saves $900/month on output alone. At scale, this is significant.
Model-by-Model Breakdown
Five Mistral models split by use case: Large 3 for output-heavy flagship work, Medium 3 for balanced production, Small 3.1 for high-volume, Ministral 8B for ultra-budget, Codestral for code with 256K context.
Large 3 — Flagship
| Spec | Value |
|---|---|
| Input/M | $2.00 |
| Output/M | $6.00 |
| Context | 128K |
| Strengths | Reasoning, code, multilingual |
What it does well: Strong reasoning capabilities, excellent multilingual performance (especially European languages), competitive coding scores. Output pricing makes it uniquely cost-effective for generation-heavy workloads.
Trade-offs: 128K context limit (vs 1M+ on GPT/Claude/Gemini). Lower absolute quality than Opus 4.6 or GPT-5.4 Pro on the hardest tasks.
Best for: Teams that generate more output than input and need premium quality without premium output prices.
Medium 3 — Balanced
| Spec | Value |
|---|---|
| Input/M | $0.40 |
| Output/M | $2.00 |
| Context | 128K |
The mid-tier sweet spot. Cheaper than GPT-5.4 Mini on both input ($0.40 vs $0.75) and output ($2.00 vs $4.50). Quality is competitive for most production tasks.
Best for: General production workloads where GPT Mini or Haiku feel overpriced.
Small 3.1 — Budget Production
| Spec | Value |
|---|---|
| Input/M | $0.20 |
| Output/M | $0.60 |
| Context | 128K |
Directly competes with Gemini Flash ($0.15/$0.60). Near-identical pricing with potentially better quality on European language tasks.
Best for: High-volume classification, extraction, and simple generation where every cent per token matters.
Ministral 8B — Ultra Budget
| Spec | Value |
|---|---|
| Input/M | $0.10 |
| Output/M | $0.10 |
| Context | 128K |
$0.10/$0.10 is Mistral's answer to Groq Llama 8B ($0.05/$0.08). Slightly more expensive but runs on Mistral's infrastructure with no rate limit surprises.
Codestral — Code Specialist
| Spec | Value |
|---|---|
| Input/M | $0.30 |
| Output/M | $0.90 |
| Context | 256K |
Purpose-built for code generation. 256K context (double Large 3's limit) handles large codebases. Pricing sits between Small and Medium — a reasonable premium for specialized code capability.

What's the Bottom Line on Mistral Pricing?
Mistral Large 3's $6/M output is the cheapest flagship output price in the market — saves 40-60% vs GPT/Claude on output-heavy workloads. The 128K context cap is the only real reason to look elsewhere. Mistral's pricing strategy in 2026 is built around one killer advantage: output token cost. Large 3 at $6/M output is 2.5x cheaper than GPT-5.4 and Claude Sonnet ($15/M) while delivering competitive quality. For any workload where output tokens exceed input tokens — content generation, code writing, detailed analysis — Mistral saves 40-60% compared to OpenAI and Anthropic.
The limitation is context window: 128K across the board (256K for Codestral) vs 1M+ from GPT, Claude, and DeepSeek. If your workloads fit within 128K, Mistral is an underpriced option that more teams should be evaluating.
