GPT-5
GPT-5 is OpenAI's unified flagship — a single model that scales its reasoning effort up or down to match the task, rather than making you pick a separate variant. The result shows up most clearly in hard technical work: a perfect AIME 2025 score with tools, 74.9% on SWE-bench Verified, and a 1.6% error rate on medical benchmark HealthBench make it one of the more capable models available for code, math, and domain-specific research. Its 400,000-token context window handles large codebases and lengthy documents without truncation. Users consistently praise the step-up in accuracy and the meaningful reduction in hallucinations over GPT-4o. The honest caveat: GPT-5 trades warmth for precision. Early adopters widely noted that responses are shorter, cooler, and noticeably less conversational than its predecessor — a real shift if personality and back-and-forth rapport matter to your workflow. Latency is also substantial; extended reasoning produces a time-to-first-token around 68 seconds, which rules it out for anything requiring snappy replies.

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.
