Too close to call
It is close. Our weighted score puts them within a point (o4-mini-deep-research 37/100, Qwen3 Coder Plus 37/100, Jamba Large 29/100), so choose by what matters most for your work: Qwen3 Coder Plus on price and Qwen3 Coder Plus 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: Jamba Large, o4-mini-deep-research or Qwen3 Coder Plus?
It is close. Our weighted score puts them within a point (o4-mini-deep-research 37/100, Qwen3 Coder Plus 37/100, Jamba Large 29/100), so choose by what matters most for your work: Qwen3 Coder Plus on price and Qwen3 Coder Plus 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, Jamba Large, o4-mini-deep-research or Qwen3 Coder Plus?
Qwen3 Coder Plus is cheaper at $1.00 input / $5.00 output per million tokens (official Alibaba API price). o4-mini-deep-research costs $1.80 input / $7.20 output per million tokens (median across 1 API provider); Jamba Large costs $2.00 input / $8.00 output per million tokens (official AI21 Labs API price). At a typical mix of three input tokens to one output token, that is $2.00 per million tokens for Qwen3 Coder Plus versus $3.15 for o4-mini-deep-research (1.6× as much) and $3.50 for Jamba Large (1.8× as much).
Which scores higher on benchmarks?
There is no independent benchmark that covers all three models yet. Jamba Large has not been scored yet, o4-mini-deep-research has not been scored yet and Qwen3 Coder Plus has not been scored yet.
Which is better for coding?
There are no published SWE-bench Verified results for Jamba Large, o4-mini-deep-research and Qwen3 Coder Plus yet, so there is no like-for-like coding score. Test both on a sample of your own tasks. All three support tool calling for agent workflows.
Which has the bigger context window?
Qwen3 Coder Plus has the largest context window at 1,048,576 tokens, against 256,000 for Jamba Large and 200,000 for o4-mini-deep-research. Maximum output per response: Jamba Large up to 4,096, o4-mini-deep-research up to 100,000, Qwen3 Coder Plus up to 65,536 tokens.

Which is newer?
Qwen3 Coder Plus is the newest, released Jul 23, 2025. Jamba Large came out Jul 3, 2025; o4-mini-deep-research came out Jun 26, 2025. Knowledge cutoff: Jamba Large Aug 22, 2024, o4-mini-deep-research May 2024, Qwen3 Coder Plus Apr 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.
