DeepSeek DeepSeek R1.0528 (OpenRouter, 65,336-token context) versus Zai Org Glm 4.6 (Novita AI, 204,800-token context). DeepSeek DeepSeek R1.0528 is cheaper by 4% on a blended token mix. DeepSeek DeepSeek R1.0528 uniquely supports prompt caching. Zai Org Glm 4.6 uniquely supports parallel tool calls and structured output (json schema). 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 R1.0528 vs Zai Org Glm 4.6
DeepSeek DeepSeek R1.0528 and Zai Org Glm 4.6 are priced within 4% 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.
Zai Org Glm 4.6 ships a 204,800-token context window, 3.1x larger than DeepSeek DeepSeek R1.0528's 65,336 tokens. That headroom matters for long-document RAG pipelines, multi-turn agent sessions that accumulate tool-call history, and codebases where the entire repository needs to fit in a single prompt. If your average prompt stays under 65,336 tokens, the extra context on Zai Org Glm 4.6 is insurance you may never use — and DeepSeek DeepSeek R1.0528 may win on other axes.
On capability surface area, the models diverge: DeepSeek DeepSeek R1.0528 supports prompt caching where the other does not; Zai Org Glm 4.6 supports parallel tool calls where the other does not; Zai Org Glm 4.6 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 | DeepSeek DeepSeek R1.0528 | Zai Org Glm 4.6 | Delta |
|---|---|---|---|
| Startup 10K requests/day | $279 /mo | $297 /mo | $18.00/mo |
| Mid-market 100K requests/day | $2,790 /mo | $2,970 /mo | $180/mo |
| Enterprise 1M requests/day | $27,900 /mo | $29,700 /mo | $1,800/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.
When to choose which
Picked from the data above — not vendor marketing. Match the rules to your workload, not the other way around.
Your workload needs long context — Zai Org Glm 4.6 fits 204,800 tokens versus the other model's 65,336, enough headroom for full books, large codebases, or 100+ page documents in one shot.
You re-send the same large system prompt across requests — DeepSeek DeepSeek R1.0528 supports prompt caching, cutting input cost on repeat hits.
Capability diff — what you gain and lose on the swap
A specific list of what each model has that the other doesn't. If your workload depends on a row in Only DeepSeek DeepSeek R1.0528, switching to Zai Org Glm 4.6 means re-architecting that path (and vice versa).
- • Prompt caching
- • Parallel tool calls
- • Structured output (JSON schema)
Capabilities both share (3)
- ✓ Function calling
- ✓ Streaming
- ✓ Native reasoning mode
Migration considerations
Concrete differences to wire through your stack before you flip traffic from one to the other.
- Context window changes up 213% when moving from DeepSeek DeepSeek R1.0528 (65,336) to Zai Org Glm 4.6 (204,800). Re-check any prompt that relies on cramming long history or documents.
- Max output tokens differ: 8,192 on DeepSeek DeepSeek R1.0528 vs 131,072 on Zai Org Glm 4.6. Long-form generation tasks may truncate differently — adjust streaming UI and chunking accordingly.
- DeepSeek DeepSeek R1.0528 has capabilities Zai Org Glm 4.6 lacks: Prompt caching. Switching to Zai Org Glm 4.6 means re-architecting any flow that depends on these.
- Zai Org Glm 4.6 has capabilities DeepSeek DeepSeek R1.0528 lacks: Parallel tool calls, Structured output (JSON schema). Worth wiring through the agent design before commit.
- Provider changes from OpenRouter to Novita AI. 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 DeepSeek DeepSeek R1.0528 vs Zai Org Glm 4.6 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 DeepSeek DeepSeek R1.0528 primary, mirror 20% of traffic to Zai Org Glm 4.6 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.
