Grok Code Fast 1 vs Mistral Small 4
Updated July 30, 2026. Public scores include evidence status and uncertainty. They are not guarantees for a specific workload.
The public evidence has no benchmark result shared by both models, so it does not support a quality verdict. Use the documented cost, context, and runtime rows instead.
0 results are shared. Category rows based on different benchmark sets are marked directional and do not name a winner.
Which one for your work
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.
Chat turn cost
1K fresh input + 500 output tokens
Mistral Small 4

What is actually comparable
Shared results can support a head-to-head reading. Results present for only one model describe coverage, not superiority.

Shape of the matched evidence
Only shared public evidence is shown. Sparse evidence stays a ruled list rather than being closed into a radar shape.
A shared-evidence shape is not available.
BenchLM does not draw a radar or infer missing axes when the matched evidence is too sparse.
What each workload costs
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.

If you already use one of these models
- Deployment change
- The models list different providers, so authentication, endpoint behavior, limits, and feature support may change.
- Quality signal
- The public evidence has no benchmark result shared by both models, so it does not support a quality verdict.
- Workload cost
- Repository review: $0.0145 vs $0.0093. Cache-heavy agent loop: $0.059 vs $0.039.
- Context tradeoff
- Both models list 256K.
Run the same representative tasks against both endpoints before changing production traffic.

Frequently asked questions
Which is better, Grok Code Fast 1 or Mistral Small 4?
The public evidence has no benchmark result shared by both models, so it does not support a quality verdict. The page therefore keeps the decision tied to the specific documented workload.
Which is better for coding, Grok Code Fast 1 or Mistral Small 4?
The published evidence does not provide a shared weighted coding basis for both models, so BenchLM does not name a coding winner.
Which is better for agentic tasks, Grok Code Fast 1 or Mistral Small 4?
The published evidence does not provide a shared weighted agentic tasks basis for both models, so BenchLM does not name a agentic tasks winner.
Which costs less, Grok Code Fast 1 or Mistral Small 4?
For the stated presets, chat costs $0.00095 on Grok Code Fast 1 and $0.00045 on Mistral Small 4; repository review costs $0.0145 and $0.0093; the cache-heavy agent loop costs $0.059 and $0.039. Grok Code Fast 1 has no published cached-input rate, so cached tokens use its listed input rate. Mistral Small 4 has no published cached-input rate, so cached tokens use its listed input rate.
Which has the larger context window, Grok Code Fast 1 or Mistral Small 4?
Both models list the same context window, 256K.
