04 — Questions

Which should you choose?

Which is better: Sarvam-M, GPT-5 Chat or Solar Pro 2?

GPT-5 Chat is the better all-round choice, scoring 39/100 against Solar Pro 2 (26) and Sarvam-M (6). It leads on context window. The score weighs inputs & features 60%, context window 40%. None of the shared benchmarks cover every model here yet, so capability is left out of this verdict.

Which is cheaper, Sarvam-M, GPT-5 Chat or Solar Pro 2?

Solar Pro 2 is cheaper at $0.25 input / $0.25 output per million tokens (official Upstage API price). GPT-5 Chat costs $1.25 input / $10.00 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 $3.44 for GPT-5 Chat (14× as much). Sarvam-M has no published per-token price.

Which scores higher on benchmarks?

There is no independent benchmark that covers all three models yet. Sarvam-M has not been scored yet, GPT-5 Chat 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 Sarvam-M, GPT-5 Chat 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 Sarvam-M and GPT-5 Chat does not support tool calling, which most coding agents need.

Which has the bigger context window?

GPT-5 Chat has the largest context window at 400,000 tokens, against 65,536 for Solar Pro 2 and 32,768 for Sarvam-M. Maximum output per response: Sarvam-M up to 32,768, GPT-5 Chat up to 128,000, Solar Pro 2 up to 8,192 tokens.

Which can read images, PDFs, audio or video?

Sarvam-M accepts text; GPT-5 Chat accepts text and images; Solar Pro 2 accepts text. GPT-5 Chat handles the widest range of inputs.

Are any of these open source?

Sarvam-M publishes its weights (Apache 2.0) and can be self-hosted; GPT-5 Chat and Solar Pro 2 is proprietary.

Which is newer?

GPT-5 Chat is the newest, released Aug 7, 2025. Sarvam-M came out May 20, 2025; Solar Pro 2 came out May 20, 2025. Knowledge cutoff: GPT-5 Chat Sep 30, 2024, 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.
