Too close to call
It is close. Our weighted score puts them within 2 points (Solar Pro 2 51/100, GLM-4.5V 48/100, Morph V3 Fast 32/100), so choose by what matters most for your work: Solar Pro 2 on price and Morph V3 Fast for long inputs. The score weighs price 50%, inputs & features 30%, context window 20%. None of the shared benchmarks cover every model here yet, so capability is left out of this verdict.

Which should you choose?
Which is better: GLM-4.5V, Morph V3 Fast or Solar Pro 2?
It is close. Our weighted score puts them within 2 points (Solar Pro 2 51/100, GLM-4.5V 48/100, Morph V3 Fast 32/100), so choose by what matters most for your work: Solar Pro 2 on price and Morph V3 Fast for long inputs. The score weighs price 50%, inputs & features 30%, context window 20%. None of the shared benchmarks cover every model here yet, so capability is left out of this verdict.
Which is cheaper, GLM-4.5V, Morph V3 Fast or Solar Pro 2?
Solar Pro 2 is cheaper at $0.25 input / $0.25 output per million tokens (official Upstage API price). GLM-4.5V costs $0.60 input / $1.80 output per million tokens (official Z.AI API price); Morph V3 Fast costs $0.80 input / $1.20 output per million tokens (median across 5 API providers). At a typical mix of three input tokens to one output token, that is $0.25 per million tokens for Solar Pro 2 versus $0.90 for GLM-4.5V (3.6× as much) and $0.90 for Morph V3 Fast (3.6× as much).
Which scores higher on benchmarks?
There is no independent benchmark that covers all three models yet. GLM-4.5V has not been scored yet, Morph V3 Fast has not been scored yet and Solar Pro 2 has not been scored yet.
Which is better for coding?
There are no published SWE-bench Verified results for GLM-4.5V, Morph V3 Fast and Solar Pro 2 yet, so there is no like-for-like coding score. Test both on a sample of your own tasks. Note that Morph V3 Fast does not support tool calling, which most coding agents need.
Which has the bigger context window?
Morph V3 Fast has the largest context window at 262,144 tokens, against 65,536 for Solar Pro 2 and 64,000 for GLM-4.5V. Maximum output per response: GLM-4.5V up to 16,384, Morph V3 Fast up to 131,072, Solar Pro 2 up to 8,192 tokens.
Which can read images, PDFs, audio or video?
GLM-4.5V accepts text, images and video; Morph V3 Fast accepts text; Solar Pro 2 accepts text. GLM-4.5V handles the widest range of inputs.
Are any of these open source?
GLM-4.5V publishes its weights and can be self-hosted; Morph V3 Fast and Solar Pro 2 is proprietary.
Which is newer?
GLM-4.5V is the newest, released Aug 11, 2025. Morph V3 Fast came out Jul 7, 2025; Solar Pro 2 came out May 20, 2025. Knowledge cutoff: GLM-4.5V Apr 2025, Solar Pro 2 Mar 2025.
How do you decide the winner?
Each model gets a 0–100 score on capability (50%, independent benchmark results); price (25%, blended price per million tokens (3 input : 1 output), log scale); inputs & features (15%, image, PDF, audio and video input, tool calling, structured output and reasoning); context window (10%, maximum tokens per request, log scale). Dimensions missing for any model are dropped and the remaining weights rescaled, so every model is judged on the same evidence. Specs and prices come from public model listings and the labs’ own API pages; capability scores come from independent benchmark runs. Data updated Nov 2, 2026.
