Choose GLM-5.3-Flash for
- Bulk document and image processing
- Routine steps planned by a stronger model
- Running AI on your own servers
Cheap enough for bulk work at roughly a tenth of GLM-5.3's list price, scoring 28 against 32 on Artificial Analysis's index; despite the name it is not fast.
Caveats: Slow on Z.ai's own service: about 60 tokens (word-pieces) a second, under half the speed of the fast models on this board. Users report less consistent output than the full GLM-5.3; the common pattern is a stronger model writing the plan and this one carrying it out. Running it yourself still needs a server with several high-end graphics cards. Not found on a major US cloud this run: Z.ai's own service or your own servers only.
Choose MiMo-V2.6-Pro for
- Overnight batch analysis
- Running AI on your own servers
- Replacing a mid-priced closed model
Xiaomi's open model costs about a fifteenth of Claude Opus 5.5 at list price and scores 30 on Artificial Analysis's index, level with the other open leaders; it is slow and long-winded.
Caveats: It writes long chains of working-out even on simple edits, which you pay for and wait for. About 47 tokens (word-pieces) a second on Xiaomi's own service, far slower than the fast models here. The only place to buy we confirmed is OpenRouter, a reseller that passes requests to Xiaomi and four other hosts; no major US cloud was found carrying it. The blind-vote ranking (Arena) rests on about 4,000 votes and is still settling. It ranks 7th because the scoring marks every model on where a business can buy it, and one reseller is the only route we confirmed. Places 3 to 7 sit within two points of each other, which is a tie.
What people running them say
GLM-5.3-Flash: A developer's month-long diary on Hacker News, a developer forum ('One month coding with GLM 5.3 Flash', 233 upvotes), reports a total bill of $68 for a month of having the model write and change software largely on its own; commenters agreed that figure 'is the headline'. The pattern they describe is to have the larger GLM-5.3 write the plan and Flash carry it out; one user notes that given an unambiguous plan 'GLM 5.3 Flash executes it just fine'. The complaints: on Z.ai's own service it is 'too slow for execution, despite the name', and the full model is 'way more consistent'.
MiMo-V2.6-Pro: Hacker News, a developer forum (1,130 upvotes), was won over less by test scores than by Xiaomi's openness: a live view of the model's training, with progress charts, dropped datasets and running cost estimates. Users call it 'incredibly cheap' for test results level with Meta's Muse Spark and say it keeps DeepSeek and GLM 'in check'. The complaints agree: 'faster than DeepSeek but still much slower than leading models', and it 'seems to overthink way too much'. Several recommend buying it through OpenRouter, a reseller, rather than the vendor's own service in China.

Scores come from the Models at Work leaderboard: Score is 0 to 100 and computed, not typed. 40% is independent testing (Artificial Analysis, Arena, Scale, Epoch, Vals and others; each test is scaled against the best score on this board, and tests of real work, such as finished freelance projects or professional tasks, count double the exams). 30% is price: the vendor's list price for a typical mix of reading and writing, on a fixed scale from $0.05 to $60 per million tokens, so a model that costs a fifth as much gains real ground. 15% is what people report after running it, from Signals and linked threads. 15% is fit: how much text it can take in at once and where a business can get it (the products and clouds that carry it), with a small credit for open weights. A missing component drops out and the rest are reweighted. A model with no independent test yet is provisional and ranks below every measured one. Within three points is a tie. Vendor-published figures are labelled and never counted. Prices are vendor list prices where published; a typical mix assumes three parts reading to one part writing.
