Bottom line — Claude Haiku 4.5 (2025-10-01) vs Qwen3 Next 80B A3b Instruct
Claude Haiku 4.5 (2025-10-01) and Qwen3 Next 80B A3b Instruct target overlapping workloads but differ sharply on economics. Qwen3 Next 80B A3b Instruct runs roughly 78% cheaper on a blended input-plus-output token mix, which translates to approximately $4,830 per month at mid-market volume (100K requests/day). The gap compounds at enterprise scale, making the cost axis the first filter most teams apply when deciding between these two models.
On capability surface area, the models diverge: Claude Haiku 4.5 (2025-10-01) supports vision input where the other does not; Claude Haiku 4.5 (2025-10-01) supports pdf input where the other does not; Claude Haiku 4.5 (2025-10-01) supports structured output (json schema) where the other does not. These differences are binary — either your workload needs the capability or it does not. Check whether any critical path in your agent pipeline depends on a capability only one model provides before committing to a migration.
For teams evaluating both models, the recommended path is a shadow A/B test: route production traffic through an OpenAI-compatible gateway, mirror a percentage to the candidate model, score both responses with an automated evaluator (faithfulness, tool-call correctness, latency), and compare cohort-level metrics over two weeks. Future AGI Agent Command Center supports this pattern with a single `base_url` change and built-in evaluators from the ai-evaluation SDK.

Cost at scale: monthly spend at three usage volumes
Estimated monthly cost assuming 1,000 input + 200 output tokens per request — a realistic chat-agent shape. Adjust your own usage in the calculator at the top of this page for an exact number.
| Scale | Claude Haiku 4.5 (2025-10-01) | Qwen3 Next 80B A3b Instruct | Delta |
|---|---|---|---|
| Startup 10K requests/day | $600 /mo | $117 /mo | $483/mo |
| Mid-market 100K requests/day | $6,000 /mo | $1,170 /mo | $4,830/mo |
| Enterprise 1M requests/day | $60,000 /mo | $11,700 /mo | $48,300/mo |
At enterprise scale (1M requests/day), a difference of even ~10% in unit price compounds into thousands of dollars per month. Cached input pricing and batch tiers can shift this further — both are surfaced on each model's own page.

Migration considerations
Concrete differences to wire through your stack before you flip traffic from one to the other.
- Max output tokens differ: 64,000 on Claude Haiku 4.5 (2025-10-01) vs 65,536 on Qwen3 Next 80B A3b Instruct. Long-form generation tasks may truncate differently — adjust streaming UI and chunking accordingly.
- Claude Haiku 4.5 (2025-10-01) has capabilities Qwen3 Next 80B A3b Instruct lacks: Vision input, PDF input, Structured output (JSON schema), Prompt caching, Native reasoning mode. Switching to Qwen3 Next 80B A3b Instruct means re-architecting any flow that depends on these.
- Provider changes from Anthropic to Alibaba DashScope. API authentication, rate-limit policy, regional availability, and billing all shift. Most teams route through an OpenAI-compatible gateway (e.g., Future AGI Agent Command Center) so the swap is a single `base_url` change instead of an SDK rewrite.
How to A/B test Claude Haiku 4.5 (2025-10-01) vs Qwen3 Next 80B A3b Instruct in production
If you're stuck between the two, run them side-by-side on real traffic. Four steps the Future AGI team uses internally:
- 1. Point your existing OpenAI SDK at
https://gateway.futureagi.com/v1. No code change beyondbase_urland a virtual key. - 2. Mark Claude Haiku 4.5 (2025-10-01) primary, mirror 20% of traffic to Qwen3 Next 80B A3b Instruct in shadow mode. Both responses are logged; only the primary is served to users.
- 3. Score every shadow response with an evaluator — faithfulness, tool-call correctness, response latency, cost. Built-in evaluators in ai-evaluation cover the common axes.
- 4. Compare cohort-level metrics after two weeks. Switch primary when the candidate wins on what matters to your workload — and stays within your latency budget.
