Complex reasoning, code and long-running agents
Test flagship models on your own production-shaped tasks, with special attention to tool reliability and recovery from failure.
GPT-5.6 Sol · Claude Opus 5Six leading commercial AI models, compared on one practical page. No made-up overall winner—just three useful questions: what can it do, what will it cost, and when should you avoid it?
Recommendations summarise vendor positioning, API capability and price structure. They are not cross-model benchmark results.

GPT-5.6 Sol · Claude Opus 5Gemini's native multimodal stack and Google ecosystem deserve an early test, though the Pro model is still marked Preview.
Gemini 3.1 Pro PreviewDeepSeek publishes a notably low unit price. Benchmark throughput, latency, governance and target-language quality before launch.
DeepSeek V4-ProFor Singapore-based regional teams, compare data residency, service availability and English–Chinese quality. Qwen also offers a mainland China cloud path and CNY pricing.
Qwen3.7-MaxPrices show standard real-time API input / output cost per million tokens. Caching, Batch, tools, long context and regional rates may differ.

The suggested fit is a starting point. Any procurement decision still needs internal testing for quality, security, latency and total cost.
A flagship reasoning and coding model with broad tool support for complex professional work.
Built for complex agentic coding and enterprise work, with adaptive thinking and multi-cloud access.
Focused on multimodal work, difficult problems, agents and rapid coding; currently in Preview.
Designed for agentic software, engineering and workflows, with reasoning, function calling and structured output.
One model supports thinking and non-thinking modes and is compatible with OpenAI- and Anthropic-style APIs.
A 1M-context thinking / non-thinking model with CNY pricing and a mainland China cloud option.
This sketch covers standard input and output tokens only. It excludes caching, search, tools, storage, regional pricing, Batch and discounts.
100,000 input + 20,000 output tokens; standard real-time estimate.
Stability with your tools, data and recovery paths predicts production performance better than a single public leaderboard score.
Window size is only an input ceiling. Test retrieval, attention decay, time to first token and tiered pricing separately.
Training use, log retention and regional processing can differ across free tiers, paid APIs, enterprise contracts and cloud resellers.
Output verbosity, retries, tool calls, cache hits and human review often shape the bill more than the headline token rate.
Models and prices move quickly. Recheck the vendor page on the day you buy or launch.
