GPT-5.4 is the best AI for API development because it is strongest at endpoint design, implementation tradeoffs, schema reasoning, and integration debugging.
The shortest way to see the safest default, the lower-cost option, and the specialist pick before you read deeper.
GPT-5.4 is the safest overall answer here when you want the strongest default instead of the lowest list price.
Switch the scoring lens to see whether the top answer changes when you care more about cost, speed, or long-document work.

Best daily driver for coding and writing — the model most developers actually reach for.
Ranks models by the broadest mix of coding, writing, research, and long-context usefulness.
You specifically need desktop-control capabilities (GPT-5.4) or the absolute highest coding ceiling (Opus 4.6).
The fastest way to see where the recommendation shifts when your priority changes.
Only frontier model that can control a desktop via API (click, type, navigate)
Strong at multi-step agentic tasks and autonomous workflows
Competitive coding performance with 74.9% SWE-bench score
Claude Opus 4.6 and Sonnet 4.6 outperform it on pure coding benchmarks
Smaller context window (272K) vs Gemini 3.1 Pro (2M) for research

Most businesses get the best results pairing one premium model for quality work with one budget model for volume — rather than forcing a single model to do everything.
Meta: Llama 3.1 8B Instruct is the lower-cost option to start with when you still need useful output at scale.
Claude Sonnet 4.6 is the better pick when response speed matters more than maximum reasoning depth.
GPT-5.4 is the best API-development model when tradeoffs and correctness matter.
GPT-5.2 Mini is the best lower-cost generalist for technical build work.
Codestral 25.01 is the better coding specialist for prompt-heavy engineering throughput.
Use GPT-5.4 for API design and debugging where bad assumptions are expensive.
Use GPT-5.2 Mini for balanced cost and versatility.
Use Codestral for fast coding assistance when the job is mostly implementation.
