Field rank #97 / 100
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 →

Model benchmark FAQ

Llama 3.1 Instruct 8B for vibe coding and agentic engineering

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

What is Llama 3.1 Instruct 8B's Vibe Coding Index?

Llama 3.1 Instruct 8B has a Vibe Coding Index of 4.1/100 and is #97 of 100 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 Llama 3.1 Instruct 8B rank for vibe coding?

For vibe coding, Llama 3.1 Instruct 8B's strongest practical area is Routine debugging at 0.7/10, ranking #97 of 100 models in TheVibeFather rankings.

Is Llama 3.1 Instruct 8B good for agentic coding and autonomous tasks?

Llama 3.1 Instruct 8B scores 0.2/10 for tool use and workflow execution and 0.2/10 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 Llama 3.1 Instruct 8B have?

The current sourced benchmark profile for Llama 3.1 Instruct 8B is Intelligence 8/100, Coding 5/100, Agentic 1/100. 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 Llama 3.1 Instruct 8B cost for agentic engineering?

The current benchmark uses a 3 to 1 input-to-output blend of $0.03 per million blended tokens. That places it #4 of 105 by price, where a lower rank number means less expensive.

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 Llama 3.1 Instruct 8B.
