Author @godofprompt says an upcoming open-weight model — released this week under the MIT license — offers a 1M-token context and costs about one-tenth of Fable 5. They argue the GLM family is the strongest open-weights coding line, with GLM-5 achieving ~78% on SWE-bench Verified, ~3 points shy of top closed models.
Model will cost roughly one-tenth of Fable 5's price and supports a 1M-token context window.
Why it's a real option, not a sad downgrade:
Roughly a tenth of Fable 5's price. 1M-token context.
Open weights under MIT, releasing this week.
And the GLM line is the best open-weights coding family right now, GLM-5 hit about 78% on SWE-bench Verified, within 3 points of the top closed models.
