DeepSeek V4-Flash vs GLM 4.7

DeepSeek · China  |  Z.ai · China · Updated June 2026

Quick verdict

Pick DeepSeek V4-Flash for exceptional value — artificial analysis intelligence index 52 at just $0.14/$0.28 per million tokens or mit-licensed open weights — free to self-host or run via a western host. Pick GLM 4.7 for genuinely permissive open weights — an mit-licensed 358b mixture-of-experts with no commercial restrictions or strong agentic coding for the price — 73.8% on swe-bench verified undercut most closed frontier models at launch. On a tight budget at scale, DeepSeek V4-Flash is the value pick.

DeepSeek V4-Flash (DeepSeek) and GLM 4.7 (Z.ai) are two of the models people most often weigh against each other in 2026. DeepSeek V4-Flash is deepSeek's MIT-licensed open-weight model — arguably the best value-per-intelligence available, scoring 52 on the independent AA Index at just $0.14/$0.28 per million tokens. GLM 4.7 is an MIT-licensed 358B open mixture-of-experts with strong 73.8% SWE-Bench Verified coding — but two generations behind GLM 5.2. They diverge most on price and context window — each quantified below from the models' real specs.

Who wins what

Exceptional value — Artificial Analysis Intelligence Index 52 at just $0.14/$0.28 per million tokens

DeepSeek V4-Flash

At $0.14/$0.28 per 1M tokens it undercuts GLM 4.7 ($0.6/$2.2 per 1M tokens), and that gap compounds at volume.

MIT-licensed open weights — free to self-host or run via a Western host

DeepSeek V4-Flash

DeepSeek's MIT-licensed open-weight model — arguably the best value-per-intelligence available, scoring 52 on the independent AA Index at just $0.14/$0.28 per million tokens — and it runs cheaper at $0.14/$0.28 per 1M tokens.

1M-token context window

DeepSeek V4-Flash

Its 1M window holds about 4.9× more than GLM 4.7's 200K in a single prompt.

Genuinely permissive open weights — an MIT-licensed 358B mixture-of-experts with no commercial restrictions

GLM 4.7

GLM 4.7 lists genuinely permissive open weights — an MIT-licensed 358B mixture-of-experts with no commercial restrictions among its strengths; DeepSeek V4-Flash does not.

Strong agentic coding for the price — 73.8% on SWE-Bench Verified undercut most closed frontier models at launch

GLM 4.7

DeepSeek V4-Flash is comparatively weak here — coding/agentic figures like Terminal-Bench 82.7 are DeepSeek's own, not independently reproduced

An unusually generous 128K maximum output, which suits bulk refactors and long generation

GLM 4.7

GLM 4.7 lists an unusually generous 128K maximum output, which suits bulk refactors and long generation among its strengths; DeepSeek V4-Flash does not.

Lowest cost at scale

DeepSeek V4-Flash

At $0.14/$0.28 per 1M tokens, it is the cheaper of the two — the gap dominates the bill on high-volume workloads.

Largest single-prompt input

DeepSeek V4-Flash

Its 1M window is about 4.9× larger than GLM 4.7's 200K, fitting roughly 1,500 pages in one prompt.

Which should you pick?

A cost-sensitive startup shipping high volume

DeepSeek V4-Flash

At $0.14/$0.28 per 1M tokens it undercuts GLM 4.7, and on millions of tokens that margin decides the monthly bill.

Someone analysing very long documents or codebases

DeepSeek V4-Flash

Larger 1M window fits more in one prompt.

Anyone whose priority is exceptional value — artificial analysis intelligence index 52 at just $0.14/$0.28 per million tokens

DeepSeek V4-Flash

It is specifically built for that.

Anyone whose priority is genuinely permissive open weights — an mit-licensed 358b mixture-of-experts with no commercial restrictions

GLM 4.7

That is its strongest area.

DeepSeek V4-Flash: where it fits

DeepSeek's MIT-licensed open-weight model — arguably the best value-per-intelligence available, scoring 52 on the independent AA Index at just $0.14/$0.28 per million tokens. Released July 31, 2026 by DeepSeek, it is built for exceptional value — Artificial Analysis Intelligence Index 52 at just $0.14/$0.28 per million tokens, mIT-licensed open weights — free to self-host or run via a Western host, 1M-token context window, and strong coding and agentic performance for the price (DeepSeek reports 82.7 on Terminal-Bench 2.1).

Its trade-offs are real: coding/agentic figures like Terminal-Bench 82.7 are DeepSeek's own, not independently reproduced, text and code focused — not a full multimodal model, deepSeek's own hosted API stores data in China; self-host or use a Western host for privacy, and below the top frontier models on overall intelligence. At $0.14 in / $0.28 out per million tokens, it sits in the budget price band.

GLM 4.7: where it fits

An MIT-licensed 358B open mixture-of-experts with strong 73.8% SWE-Bench Verified coding — but two generations behind GLM 5.2. Released December 22, 2025 by Z.ai, it is built for genuinely permissive open weights — an MIT-licensed 358B mixture-of-experts with no commercial restrictions, strong agentic coding for the price — 73.8% on SWE-Bench Verified undercut most closed frontier models at launch, an unusually generous 128K maximum output, which suits bulk refactors and long generation, and cheap long-running agent loops thanks to aggressive prompt caching.

Its trade-offs: two generations behind — GLM 5, 5.1 and 5.2 have all shipped since, and new builds should default to those, its Verified lead narrows sharply on harder evaluations like SWE-Bench Pro, and text-only with no vision, and self-hosting a 358B model is a serious hardware commitment. At $0.6 in / $2.2 out per million tokens, it sits in the budget price band.

The bottom line for this matchup

DeepSeek V4-Flash and GLM 4.7 overlap enough that the right pick depends on your specific job. DeepSeek V4-Flash costs less per token; DeepSeek V4-Flash holds the larger context; and each leads in its own area — DeepSeek V4-Flash for exceptional value — artificial analysis intelligence index 52 at just $0.14/$0.28 per million tokens, GLM 4.7 for genuinely permissive open weights — an mit-licensed 358b mixture-of-experts with no commercial restrictions. Rather than crowning one, run the same hard task through both once and let the results decide.

Frequently asked questions

Is DeepSeek V4-Flash or GLM 4.7 better for coding?

Public SWE-Bench figures are not available for DeepSeek V4-Flash, so the honest test is your own repository — run an identical real bug through both. By design, DeepSeek V4-Flash leans toward exceptional value — artificial analysis intelligence index 52 at just $0.14/$0.28 per million tokens while GLM 4.7 leans toward genuinely permissive open weights — an mit-licensed 358b mixture-of-experts with no commercial restrictions, and that positioning usually predicts which feels better on your codebase.

Which is cheaper, DeepSeek V4-Flash or GLM 4.7?

DeepSeek V4-Flash is cheaper — $0.14/$0.28 per 1M tokens vs $0.6/$2.2 per 1M tokens, roughly 4.3× apart on input.

Which has the bigger context window?

DeepSeek V4-Flash — 1M vs 200K, about 4.9× larger. Useful only if the model actually reasons over the full window, which not all do.

Can I use both DeepSeek V4-Flash and GLM 4.7 together?

Yes — a multi-model platform like LumiChats gives you DeepSeek V4-Flash, GLM 4.7 and 40+ others under one ₹69/day pass (about $1/day), so you can draft with one and cross-check with the other instead of buying two subscriptions.

Which is newer, DeepSeek V4-Flash or GLM 4.7?

DeepSeek V4-Flash — released July 31, 2026, about 7 months after GLM 4.7.
