Qwen 3.7 Max vs Opus 4.8 vs GPT-5.6 Sol (2026)
Three frontier-grade models at very different prices: GPT-5.6 Sol (peak), Claude Opus 4.8 (trusted agents), and Qwen 3.7 Max (frontier value). Here’s how they compare and when each wins.

Head to Head
| GPT-5.6 Sol | Claude Opus 4.8 | Qwen 3.7 Max | |
|---|---|---|---|
| Vendor | OpenAI | Anthropic | Alibaba |
| Tier | Peak frontier | Frontier value | Value shock |
| Input / Output (per MTok) | $5 / $30 | $5 / $25 | $1.25 / $3.75 (promo) |
| Cost / task (30K→5K) | ~$0.30 | ~$0.28 | ~$0.056 |
| SWE-Verified | — | ~80.8 (4.6) | ~80.4 |
| Terminal-Bench 2.0 | — | 65.4 (4.6) | 69.7 |
| Standout | Agents’ Last Exam 53.6 | Coding reliability (Claude Code) | Value + API compatibility |
| Context | Large | Large | 1M tokens |
GPT-5.6 Sol — peak capability
Sol is OpenAI’s frontier flagship, setting a new high of 53.6 on Agents’ Last Exam (long-running professional workflows across 55 fields), eclipsing Claude Fable 5’s adaptive-reasoning score by 13.1 points. At $5/$30, it’s priced for jobs where being right on the hardest, longest tasks beats cost. Pick Sol when the task is at the edge of model capability.
Claude Opus 4.8 — trusted agents
Opus 4.8 matches Sol’s $5 input but undercuts on output ($25 vs $30), and it’s the reliability favorite for coding and agentic workflows — the engine behind Claude Code. For production agents where judgment and consistency matter, it remains the safe default. Pick Opus 4.8 when you want frontier coding/agents you can trust in production.
Qwen 3.7 Max — frontier value
Alibaba’s Qwen 3.7 Max is the value story of mid-2026. It matches or beats Opus 4.6 on coding benchmarks — SWE-Verified ~80.4, Terminal-Bench 2.0 69.7, SWE-Pro 60.6 — and demonstrated 35+ hours of continuous autonomous coding with 1,000+ tool calls. Crucially, it’s natively compatible with both OpenAI and Anthropic API specs, so it drops into Claude Code and existing pipelines. At $1.25/$3.75 on its 50% promo (plus a 90%-off cached-input tier), it costs roughly a fifth of the US flagships per task. The one caveat: a higher abstention rate (~48%), which lowers hallucinations but means it sometimes declines rather than guesses. Pick Qwen 3.7 Max when you want frontier coding quality at open-model prices.
The Winning Pattern: Route by Risk
- Default to Qwen 3.7 Max for most coding and agent work.
- Escalate to Opus 4.8 for production agents where reliability is non-negotiable.
- Escalate to GPT-5.6 Sol for the hardest long-horizon reasoning.
Bottom Line
- Cheapest per task: Qwen 3.7 Max (~$0.056)
- Most trusted for agents: Claude Opus 4.8 (~$0.28)
- Peak capability: GPT-5.6 Sol (~$0.30)
Benchmark on your real prompts. For many teams, Qwen 3.7 Max as default with Opus/Sol on escalation is the cheapest path to frontier-quality output.
