01 — Verdict

Too close to call

It is close. Our weighted score puts them within a point (Sonar Deep Research 16/100, Step 1 (32K) 15/100, ALLaM-2-7b 0/100), so choose by what matters most for your work: Sonar Deep Research on price and Sonar Deep Research for long inputs. 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.

04 — Questions

Which should you choose?

Which is better: ALLaM-2-7b, Sonar Deep Research or Step 1 (32K)?

It is close. Our weighted score puts them within a point (Sonar Deep Research 16/100, Step 1 (32K) 15/100, ALLaM-2-7b 0/100), so choose by what matters most for your work: Sonar Deep Research on price and Sonar Deep Research for long inputs. 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, ALLaM-2-7b, Sonar Deep Research or Step 1 (32K)?

Sonar Deep Research is cheaper at $2.00 input / $8.00 output per million tokens (official Perplexity API price). Step 1 (32K) costs $2.05 input / $9.59 output per million tokens (official StepFun (Global) API price). At a typical mix of three input tokens to one output token, that is $3.50 per million tokens for Sonar Deep Research versus $3.94 for Step 1 (32K) (1.1× as much). ALLaM-2-7b has no published per-token price.

Which scores higher on benchmarks?

There is no independent benchmark that covers all three models yet. ALLaM-2-7b has not been scored yet, Sonar Deep Research has not been scored yet and Step 1 (32K) has not been scored yet.

Which is better for coding?

There are no published SWE-bench Verified results for ALLaM-2-7b, Sonar Deep Research and Step 1 (32K) yet, so there is no like-for-like coding score. Test both on a sample of your own tasks. Note that ALLaM-2-7b and Sonar Deep Research does not support tool calling, which most coding agents need.

Which has the bigger context window?

Sonar Deep Research has the largest context window at 128,000 tokens, against 32,768 for Step 1 (32K) and 4,096 for ALLaM-2-7b. Maximum output per response: ALLaM-2-7b up to 4,096, Sonar Deep Research up to 32,768, Step 1 (32K) up to 32,768 tokens.

Which can read images, PDFs, audio or video?

ALLaM-2-7b accepts text; Sonar Deep Research accepts text; Step 1 (32K) accepts text. They handle the same number of input types.

Are any of these open source?

ALLaM-2-7b publishes its weights and can be self-hosted; Sonar Deep Research and Step 1 (32K) is proprietary.

Which is newer?

Sonar Deep Research is the newest, released Feb 1, 2025. ALLaM-2-7b came out Jan 23, 2025; Step 1 (32K) came out Jan 1, 2025. Knowledge cutoff: Sonar Deep Research Jan 2025, Step 1 (32K) Jun 2024.

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 Oct 4, 2026.
