1 · Sourced signals

We start with Intelligence, Coding, Agentic benchmark evidence and preserve missing values as unverified.

2 · Practical lenses

Our code-controlled algorithm blends the native 0–100 signals by workflow and expresses the result on a stable 0–10 scale. Every required input must be present.

3 · Field ranking

Each workflow score is ranked against every model with comparable evidence, so positions update when the benchmark field changes.

The Vibe Coding Index is TheVibeFather’s code-controlled 0–100 composite for practical coding and agentic capability. Price and adoption are reported independently and never alter quality. Exact weighting remains proprietary; inputs, missing-data behavior, and per-category ranks are disclosed here. Read the benchmark methodology →

Answers update from this model’s current sourced scores, practical rankings, and verified pricing.

What is Mistral Small 3.1's Vibe Coding Index?

Mistral Small 3.1 has a Vibe Coding Index of 16.6/100 and is #63 of 86 in the current field. The index is TheVibeFather's stable composite for practical AI coding, combining independently sourced Intelligence, Coding, and Agentic benchmark signals. Price and adoption are compared separately and never inflate the quality score.

How does Mistral Small 3.1 rank for vibe coding?

For vibe coding, Mistral Small 3.1's strongest practical area is Small, well-defined code changes at 2.3/10, ranking #62 of 86 models in TheVibeFather rankings.

Is Mistral Small 3.1 good for agentic coding and autonomous tasks?

Mistral Small 3.1 scores 1.0/10 for tool use and workflow execution and 0.7/10 for long autonomous coding tasks. Those categories emphasize the Agentic benchmark signal used for multi-step planning, tool calls, edits, tests, and feedback loops.

What coding benchmark scores does Mistral Small 3.1 have?

The current sourced benchmark profile for Mistral Small 3.1 is Intelligence 15/100, Coding 26/100, Agentic 5/100. TheVibeFather converts those 0–100 signals into consistent practical 0–10 workflow scores so models can be compared for real agentic engineering work.

How much does Mistral Small 3.1 cost for agentic engineering?

The current benchmark uses a 3:1 input-to-output blend of not currently verified. A field price rank will appear when both input and output pricing are verified.

Are vibe coding, agentic coding, and agentic engineering the same?

They describe overlapping AI-assisted software workflows. Vibe coding emphasizes directing software through intent and iteration; agentic coding emphasizes a model planning and executing multi-step work with tools; agentic engineering is the broader discipline of designing, supervising, and validating those workflows. TheVibeFather benchmarks the shared capabilities behind all three terms on every model page, including Mistral Small 3.1.
