Magistral Small 1.1

Compact Transparent AI for Logic & Reasoning

What is Magistral Small 1.1?

Magistral Small 1.1 is a 24-billion parameter, open-source reasoning model from Mistral AI, focusing on precise, transparent, and stepwise outputs for technical, business, and regulated domains. Building on Mistral Small 3.1, it uses improved instruction tuning, reinforcement learning with reasoning traces from its Medium sibling, and enhanced formatting for interpretability. Outputs include clear chain-of-thought (“[THINK]...[/THINK]”) reasoning and LaTeX/Markdown support for technical tasks. It works locally on a single RTX 4090 or modern Mac, supporting efficient cloud and edge deployments.

What are the Risks & Limitations of Magistral Small 1.1

Limitations

Contextual Stability Gaps: Reasoning quality often degrades if the prompt exceeds 40k tokens.
Non-Linear Task Hurdles: Struggles with tasks that cannot be broken into sequential steps.
Hardware Entry Barriers: Requires ~47GB of VRAM for full BF16 use on local workstations.
Deterministic Tone Shift: Rigid "THINK" tags can make the final output feel overly robotic.
Knowledge Cutoff Walls: Lacks awareness of global events occurring after its 2025 training.

Risks

Infinite Reasoning Loops: Complex queries can trap the model in endless "THINK" cycles.
Trace-Based Jailbreaking: Adversarial prompts can hide harmful intent within CoT steps.
Sycophancy Tendencies: The model may prioritize logical consistency over factual truth.
Data Exposure Hazards: Reasoning traces may inadvertently reveal sensitive system prompts.
Hallucinated Logic Paths: Can produce "perfect" looking proofs that contain silent errors.

Pricing of the Magistral Small 1.1

Magistral Small 1.1 uses a usage‑based pricing model, where costs depend on the number of tokens processed, both the text you send in (input tokens) and the text the model returns (output tokens). Instead of paying a flat subscription fee, you pay only for what your application consumes, making it easy to scale from small tests to full production deployments. This flexible approach lets teams forecast costs by estimating prompt lengths, expected response size, and overall usage volume so budgets stay predictable as demand grows.

In typical API pricing tiers, input tokens are billed at a lower rate than output tokens because generating responses requires more compute effort. For example, Magistral Small 1.1 might be priced at around $1.50 per million input tokens and $6 per million output tokens under standard usage plans. Larger contexts or longer responses naturally increase total spend, so optimizing prompt design and managing response verbosity can help control overall costs. Since output tokens often represent most of the billing, keeping replies concise where possible can help reduce expenses.

To further manage spend, developers often implement prompt caching, batching, and context reuse, which lower redundant processing and reduce effective token counts. These strategies are especially useful in high‑volume environments such as conversational interfaces, automated content streams, and data analysis tools. With transparent usage‑based pricing and smart cost‑management techniques, Magistral Small 1.1 offers a predictable, scalable pricing structure suitable for a wide range of AI applications.
