Model comparison
Claude Mythos 5 vs GPT-4o mini Audio
Updated August 4, 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.

Not enough matched evidence
The page does not recommend a cost winner because at least one model cannot fit the stated workload in one request. GPT-4o mini Audio does not fit this workload in one request. GPT-4o mini Audio has no published cached-input rate, so cached tokens use its listed input rate.
Confidence: rate-fallback
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: $0.65 vs $0.0093. Cache-heavy agent loop: $0.9 vs $0.039.
- Context tradeoff
- Claude Mythos 5 has the larger documented window (1M).
Run the same representative tasks against both endpoints before changing production traffic.

Frequently asked questions
Which is better, Claude Mythos 5 or GPT-4o mini Audio?
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, Claude Mythos 5 or GPT-4o mini Audio?
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, Claude Mythos 5 or GPT-4o mini Audio?
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, Claude Mythos 5 or GPT-4o mini Audio?
For the stated presets, chat costs $0.035 on Claude Mythos 5 and $0.00045 on GPT-4o mini Audio; repository review costs $0.65 and $0.0093; the cache-heavy agent loop costs $0.9 and $0.039. GPT-4o mini Audio does not fit this workload in one request. GPT-4o mini Audio has no published cached-input rate, so cached tokens use its listed input rate.
Which has the larger context window, Claude Mythos 5 or GPT-4o mini Audio?
Claude Mythos 5 has the larger documented context window: 1M, compared with 128K.
