GPT-5.4
GPT-5.4 was built for the actual work that happens inside offices — financial modeling, legal analysis, complex codebases, and multi-step document workflows — rather than for chasing narrow benchmarks. That strategic shift shows in the numbers: it matched or outperformed human professionals in 83% of head-to-head comparisons, and developers have called its coding output "flawless," with some declaring it the definitive choice for complex software engineering work. Native computer-use capabilities let it operate browsers and desktop apps directly, and it scored above the human baseline on UI interaction tasks. The 1.05 million token context window handles large codebases and lengthy legal documents in a single pass, though you need to configure it explicitly — the default is 272K. Where GPT-5.4 falls short is nuance: it tends to interpret requests too literally, missing the intent behind ambiguous prompts in ways that Claude handles more naturally. Writing personality is another common frustration, with verbose follow-up suggestions that can feel mechanical. For structured professional tasks where thoroughness and tool integration matter more than prose feel, it is the strongest model in the GPT-5 line prior to the release of GPT-5.5.

At $0.50 per million input tokens, Qwen 3.6 Plus punches well above its price band — scoring 78.8 on SWE-bench Verified and 61.6 on Terminal-Bench 2.0, where it outpaces Claude 4.5 Opus on agentic coding tasks. The 1 million token context window lets you drop in entire codebases for security audits, multi-file refactors, or long-horizon agent sessions without chunking or worrying about cost. Always-on chain-of-thought reasoning is baked into the architecture rather than toggled per request, and native tool-calling makes it well-suited for multi-step workflows. Developers building high-volume API applications have reported generating hundreds of millions of tokens during its preview period — its first-day usage crossed one trillion tokens across platforms. That said, the long context is not a silver bullet: retrieval accuracy degrades in the middle of very long inputs, and real-world testing has surfaced instruction-following inconsistencies and occasional tool-calling failures that more mature providers handle more reliably. For cost-sensitive production deployments where coding and document analysis are the core workload, few models compete at this price.
