Source-tracked model comparison
How do GPT-4o and Claude Sonnet 4.6 costs compare for developer assistance?
Compare verified pricing and model limits for developer assistance across providers. The cost example uses a developer assistant backend workload and does not assume equal model quality.
Direct cost answer: GPT-4o is estimated at $1,312.50 per month and Claude Sonnet 4.6 at $1,740.00 for 5,000 input tokens, 1,500 output tokens, and 50,000 monthly requests. GPT-4o is $427.50 lower under these assumptions. This does not identify a quality winner.
Tracked facts

Questions to answer before choosing
- Which model produces more accepted work on the team's repositories?
- How much context is sent in a normal request?
- Which integration path creates less rollout friction?
What this estimate leaves out
The calculation does not compare coding quality and excludes indexing, execution sandboxes, and repository storage.
Latency, reliability, output quality, retries, regional processing, and provider-specific tool charges can change the practical decision.
