GLM-5.2 alternatives

14 tools we tested head to head against GLM-5.2, ranked — and what each one actually does differently.

last reviewed 26 jul 2026 · from our best 15 open-weight llms ·list curated by Onur Ozcanxin

first — what you'd be leaving

GLM-5.2 ranks #1 of 15 in our open-weight llms testing. the top-ranked open-weight model on the intelligence index, under plain unmodified mit, with a launch post that tells the truth..

95/100

first on capability and first on licence at the same time, which almost never happens — this is the default open-weight choice right now.

why people look for an alternative
  • roughly 750gb of gpu memory at fp8 — a full node
  • active-parameter count only confirmed via secondary sources
  • no published vendor statement of its weaknesses

stay with GLM-5.2 if plain unmodified mit — no traps of any kind is the thing you care about most — nothing below beats it on that.

  1. 1

    DeepSeek V4 Pro

    #2 in open-weight llms · 1.6 trillion parameters of mit-licensed coding ability, still shipping as a preview three months after its stable release was due.

    92/100

    verdictarguably the best coding model you can legally do anything with — carrying a 'preview' label that deepseek has not removed on the schedule it set itself.

  2. 2

    Mistral Large 3

    #3 in open-weight llms · europe's frontier answer under apache 2.0 — and mistral resisted the temptation to reach for its old research licence.

    89/100

    verdictthe highest-ranked open model on lmarena after gemini, licensed apache 2.0 with nothing bolted on — the main catch is that it's now eight months old.

    pros
    • +apache 2.0 with no custom mistral terms attached
    • +top open-source coding model on lmarena
    • +full size ladder from 3b to 675b under one licence

    Kimi K2.7 Code

    #4 in open-weight llms · a trillion-parameter agentic coder under 'modified mit' — where the modification only bites if you get very big.

    86/100

    verdictexcellent at the job it was built for, with a licence quirk almost nobody will hit — but which press coverage summarising it as 'mit' never mentions.

    switch forlong-running agentic engineering work, for anyone comfortably below the attribution thresholds.

    pros
    • +attribution clause only triggers at 100m users or $20m monthly revenue
    • +purpose-built for long-horizon agentic engineering
    • +~30% fewer thinking tokens than its predecessor
    • +int4 deployment reportedly fits two a100 80gb cards
    cons

    • position 31 on the artificial analysis index
    • 256k context, against 1m for the top three

    Inkling

    #5 in open-weight llms · thinking machines' first model — apache 2.0, multimodal, and unusually honest about not being the best.

    84/100

    verdictthe strongest open-weight model from a us lab, built for customisation rather than benchmarks — and its own model card says plainly that it isn't the strongest overall.

    switch forteams who want a permissive multimodal base to fine-tune rather than a leaderboard winner to deploy.

    pros
    • +apache 2.0 from a major new us lab
    • +genuinely multimodal — text, image, audio and video training
    • +up to 1m context from downloaded weights
    • +unusually candid about its own limitations
    cons
    • licence confirmed from the model card, not the raw repo file
    • behind deepseek v4 pro and kimi k2.6 on the intelligence index
    • 975b total — enterprise-scale hosting only
    • tinker api caps context at 256k, lower than the weights allow

    gpt-oss-120b

    #6 in open-weight llms · the only genuinely capable model here that fits on a single 80gb card, under clean apache 2.0.

    82/100

    verdictnearly a year old and still the most practical self-host on this list — one card, no licence questions, real agentic ability.

    • +runs on a single 80gb gpu at mxfp4
    • +5.1b active path makes cpu inference viable
    • +strong agentic tool-calling with configurable reasoning effort
    cons

    • no successor since august 2025
    • passed on the intelligence index by newer open releases
  6. 6

    DeepSeek V4 Flash

    #7 in open-weight llms · a separate model rather than a trim of v4 pro — a fifth the size, same mit licence, a twelfth the hosted price.

    81/100

    verdictthe best price-to-capability ratio in the category, and widely mistaken for a variant of v4 pro when it's its own release with its own weights.

    pros
    • +plain mit, same as v4 pro
    • +cheapest frontier-adjacent hosted rate in the market
    • +13b active — far more self-hostable than the pro tier
    • +a fifth the total size for a fraction of the capability gap
    cons
    • routinely misdescribed as a variant of v4 pro
    • 40.3% on the intelligence index — clearly below the top tier
    • inherits v4's preview-status uncertainty

    Gemma 4

    #8 in open-weight llms · the year's biggest licensing improvement — google dropped its custom terms and shipped this one under real apache 2.0.

    79/100

    verdictthree generations of custom gemma terms replaced by plain apache 2.0, on a family built to run on hardware you already own — the caveats are housekeeping rather than substance.

    • +multimodal variants that run on laptops and edge devices
    • +256k context and 140+ languages
    • +31b dense fits a single consumer gpu when quantised
    cons

    • training data cutoff of january 2025

    Qwen3.6-35B-A3B

    #9 in open-weight llms · genuinely apache 2.0 and genuinely small — and constantly confused with the closed flagship sharing its brand.

    77/100

    verdictan unusually strong small model under clean apache 2.0 — the trap is definitional, because the 'qwen' name also covers a closed api-only flagship.

    • +3b active — runs on one prosumer gpu
    • +vendor-reported 73.4 on swe-bench for its size
    • +combined thinking and non-thinking modes
    cons

    • 35b total means limited knowledge breadth
    • context length not confirmed from a primary source
    • benchmark figures are vendor-reported only

    NVIDIA Nemotron 3 Ultra

    #10 in open-weight llms · a serious frontier model whose licence nvidia's own two sets of pages cannot agree on.

    74/100

    verdictcapable, long-context and well-engineered — marked down purely because we could not establish, from nvidia's own sources, what you are agreeing to.

    72/100

    verdictevery other entry calls itself open and means the weights. ai2 publishes the training data too — which is worth more than the benchmark places it gives up.
