Overall VibeFather rating

Our complete Vibe Coding Index, expressed on the same 0–10 practical scale.

Mixed 4.4/10
Field rank #35 / 103
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

Solar Pro 4 for vibe coding and agentic engineering

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

What is Solar Pro 4's Vibe Coding Index?

Solar Pro 4 has a Vibe Coding Index of 43.8/100 and is #35 of 103 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 Solar Pro 4 rank for vibe coding?

For vibe coding, Solar Pro 4's strongest practical area is Small, well-defined code changes at 4.9/10, ranking #40 of 103 models in TheVibeFather rankings.

Is Solar Pro 4 good for agentic coding and autonomous tasks?

Solar Pro 4 scores 3.8/10 for tool use and workflow execution and 3.5/10 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 Solar Pro 4 have?

The current sourced benchmark profile for Solar Pro 4 is Intelligence 42/100, Coding 53/100, Agentic 34/100. 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 Solar Pro 4 cost for agentic engineering?

The current benchmark uses a 3 to 1 input-to-output blend of $0.05 per million blended tokens. That places it #7 of 121 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 Solar Pro 4.
