GLM 4.7 vs LongCat-2.0

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

Quick verdict

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. Pick LongCat-2.0 for near-frontier agentic coding — topped openrouter anonymously as 'owl alpha' for two months or massive native 1m context at near-linear cost via sparse attention. On a tight budget at scale, LongCat-2.0 is the value pick.

GLM 4.7 (Z.ai) and LongCat-2.0 (Meituan) are two of the models people most often weigh against each other in 2026. 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. LongCat-2.0 is a trillion-parameter, MIT-licensed open MoE delivering near-frontier agentic coding at 1M context — trained entirely on Chinese chips. They diverge most on price and context window — each quantified below from the models' real specs.

Who wins what

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; LongCat-2.0 does not.

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

GLM 4.7

LongCat-2.0 is comparatively weak here — headline scores are vendor-reported on SWE-Bench Pro, not the Verified set

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; LongCat-2.0 does not.

Near-frontier agentic coding — topped OpenRouter anonymously as 'Owl Alpha' for two months

LongCat-2.0

A trillion-parameter, MIT-licensed open MoE delivering near-frontier agentic coding at 1M context — trained entirely on Chinese chips — and it carries the larger 1M context.

Massive native 1M context at near-linear cost via sparse attention

LongCat-2.0

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

Fully MIT-licensed 1.6T-parameter mixture-of-experts (about 48B active)

LongCat-2.0

A trillion-parameter, MIT-licensed open MoE delivering near-frontier agentic coding at 1M context — trained entirely on Chinese chips — and it is the newer of the two.

Lowest cost at scale

LongCat-2.0

Its weights are open, so at volume you pay for your own hardware instead of GLM 4.7's $0.6/$2.2 per 1M tokens.

Largest single-prompt input

LongCat-2.0

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

LongCat-2.0

At Open weight (self-host / free) it undercuts GLM 4.7, and on millions of tokens that margin decides the monthly bill.

Someone analysing very long documents or codebases

LongCat-2.0

Larger 1M window fits more in one prompt.

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

GLM 4.7

It is specifically built for that.

Anyone whose priority is near-frontier agentic coding — topped openrouter anonymously as 'owl alpha' for two months

LongCat-2.0

That is its strongest area.

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 are real: 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.

LongCat-2.0: where it fits

A trillion-parameter, MIT-licensed open MoE delivering near-frontier agentic coding at 1M context — trained entirely on Chinese chips. Released July 5, 2026 by Meituan, it is built for near-frontier agentic coding — topped OpenRouter anonymously as 'Owl Alpha' for two months, massive native 1M context at near-linear cost via sparse attention, fully MIT-licensed 1.6T-parameter mixture-of-experts (about 48B active), and trained end to end on domestic Chinese chips, independent of Nvidia hardware.

Its trade-offs: a 1.6T model is extremely expensive to self-host, so most use leans on the China-hosted API, and headline scores are vendor-reported on SWE-Bench Pro, not the Verified set. As an open-weight model, its running cost is your own hardware rather than a per-token fee.

The bottom line for this matchup

GLM 4.7 and LongCat-2.0 overlap enough that the right pick depends on your specific job. LongCat-2.0 costs less per token; LongCat-2.0 holds the larger context; and each leads in its own area — GLM 4.7 for genuinely permissive open weights — an mit-licensed 358b mixture-of-experts with no commercial restrictions, LongCat-2.0 for near-frontier agentic coding — topped openrouter anonymously as 'owl alpha' for two months. Rather than crowning one, run the same hard task through both once and let the results decide.

Frequently asked questions

Is GLM 4.7 or LongCat-2.0 better for coding?

Public SWE-Bench figures are not available for LongCat-2.0, so the honest test is your own repository — run an identical real bug through both. By design, GLM 4.7 leans toward genuinely permissive open weights — an mit-licensed 358b mixture-of-experts with no commercial restrictions while LongCat-2.0 leans toward near-frontier agentic coding — topped openrouter anonymously as 'owl alpha' for two months, and that positioning usually predicts which feels better on your codebase.

Which is cheaper, GLM 4.7 or LongCat-2.0?

LongCat-2.0 is cheaper — $0.6/$2.2 per 1M tokens vs Open weight (self-host / free).

Which has the bigger context window?

LongCat-2.0 — 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 GLM 4.7 and LongCat-2.0 together?

Yes — a multi-model platform like LumiChats gives you GLM 4.7, LongCat-2.0 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, GLM 4.7 or LongCat-2.0?

LongCat-2.0 — released July 5, 2026, about 7 months after GLM 4.7.
