DeepSeek DeepSeek V3.1 Terminus vs Zai Org Glm 4.6v

DeepSeek DeepSeek V3.1 Terminus (Novita AI, 131,072-token context) versus Zai Org Glm 4.6v (Novita AI, 131,072-token context). Zai Org Glm 4.6v is cheaper by 6% on a blended token mix. Zai Org Glm 4.6v uniquely supports vision input. Use the live calculator below to plug your real usage shape into both, then route the winner via Agent Command Center for shadow A/B without code changes.

Bottom line — DeepSeek DeepSeek V3.1 Terminus vs Zai Org Glm 4.6v

DeepSeek DeepSeek V3.1 Terminus and Zai Org Glm 4.6v are priced within 6% of each other, so cost alone is not the deciding factor. The comparison comes down to capabilities, context window, and benchmark performance on the specific task shape your workload demands.

On capability surface area, the models diverge: Zai Org Glm 4.6v supports vision input 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	DeepSeek DeepSeek V3.1 Terminus	Zai Org Glm 4.6v	Delta
Startup 10K requests/day	$141 /mo	$144 /mo	$3.00/mo
Mid-market 100K requests/day	$1,410 /mo	$1,440 /mo	$30.00/mo
Enterprise 1M requests/day	$14,100 /mo	$14,400 /mo	$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.

How to A/B test DeepSeek DeepSeek V3.1 Terminus vs Zai Org Glm 4.6v 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 beyond base_url and a virtual key.
2. Mark DeepSeek DeepSeek V3.1 Terminus primary, mirror 20% of traffic to Zai Org Glm 4.6v 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.

Do DeepSeek DeepSeek V3.1 Terminus and Zai Org Glm 4.6v both support tool calling? ▾

Yes — both DeepSeek DeepSeek V3.1 Terminus and Zai Org Glm 4.6v support native function calling. Both also support structured output via JSON schema, so an agent can be ported between them with the same tool definitions.

Can DeepSeek DeepSeek V3.1 Terminus and Zai Org Glm 4.6v process images? ▾

Zai Org Glm 4.6v accepts native image input. DeepSeek DeepSeek V3.1 Terminus does not — you would need to route image-heavy workloads through Zai Org Glm 4.6v or add a separate vision model in front of DeepSeek DeepSeek V3.1 Terminus.

How do I A/B test DeepSeek DeepSeek V3.1 Terminus against Zai Org Glm 4.6v in production? ▾

Route both through an OpenAI-compatible gateway like Future AGI Agent Command Center with shadow mode enabled. Send 100% of traffic to your primary model, mirror 10–20% to the candidate, score every response with an evaluator (faithfulness, tool-call correctness, response time), and compare cohort-level metrics for two weeks. Switch when the candidate wins on the metrics that matter to your workload and stays within your latency budget.
