Updated October 7, 2026. Rank says Grok 4.5 is ahead. Price, access, and your workload can each overturn that. Public scores include evidence status and uncertainty.

Grok 4.5 has the higher public score estimate, 63.97 versus 53.93, but the 90% score intervals overlap. Treat that as a lead, not a settled winner. 7 results are shared. Category rows resting on Estimated evidence or different benchmark sets are marked directional and do not name a winner.
Recommendations appear only when a shared evidence basis or an explicit operating constraint supports the call. Secondary and unsupported use cases stay disclosed below the initial list.
Code generation, repair, and software-engineering tasks
Grok 4.5
Grok 4.5 has the higher public coding point estimate, 57.7 to 36.4, with Supported evidence for both models. The conditional ranges do not establish rank confidence.

Choose a job from the LLM Selector's task catalog to see the category row it rests on, under the same basis rules as the table below. A directional row stays directional; choosing a job never creates a winner.
The same task catalog as the LLM Selector. Each job names the evidence surface it rests on; nothing here adds a new score.

Grok 4.5 has the higher coding point estimate. Conditional score ranges do not establish rank confidence.
Coding scores combine specific tasks and setups. Match the editor, harness, and effort to your workflow.
Shared results can support a head-to-head reading. Results present for only one model describe coverage, not superiority.
Only shared public evidence is shown. Sparse evidence stays a ruled list rather than being closed into a radar shape.
Too few matched category axes support a radar. The ruled list below shows only shared benchmark results; positions use each benchmark’s normalized display scale when available.

Normalized gap 4.6Each row shows the public-lane category score for both models: the BenchAlign v5.8 lane for agentic, coding, and knowledge, and the weighted public rows elsewhere, with the same rank each model page reports. A row is like-for-like only when both scores rest on Supported evidence or the same weighted set. Directional and not-comparable rows remain visible, but they never receive a winner.

Ranks count the models scored in each category’s lane, so the agentic, coding, and knowledge denominators (BenchAlign v5.8) differ from the provisional-lane categories. Unranked scores sit on the provisional lane’s scale but never name a winner. Like-for-like rows within 0.5 points read as a practical tie.
Three fixed token mixes turn per-token rates into comparable decisions. Each scenario states context fit and whether cached input had to fall back to the published list-input rate.

Grok 4.5 has the higher public score estimate, 63.97 versus 53.93, but the 90% score intervals overlap. The higher estimate is not a decisive winner because the uncertainty ranges overlap.
Grok 4.5 has the higher public coding point estimate, 57.7 to 36.4, with Supported evidence for both models. The conditional ranges do not establish rank confidence.
Grok 4.5 has the higher public agentic tasks point estimate, 57.6 to 34.3, with Supported evidence for both models. The conditional ranges do not establish rank confidence.
For the stated presets, chat costs $0.003 on GPT-5.4 mini and $0.005 on Grok 4.5; repository review costs $0.051 and $0.118; the cache-heavy agent loop costs $0.075 and $0.16. Costs use the listed standard API rates.
Grok 4.5 has the larger documented context window: 500K, compared with 400K.
