Who wins each use case
Each row is the dimension-weighted verdict for that use case. Use case weights live in src/lib/model-battle/comparator.ts and are public.
What hardware actually runs each model
VRAM math against the canonical hardware ladder. The largest context window that fits with headroom at Q4_K_M appears in each cell.

On RTX 4090 @ Q4_K_M — bandwidth-derived estimate
Computed from each option's sustained TDP × predicted tok/s at $0.16/kWh. Cloud baseline: Claude Sonnet 4.6 (input + output).

Qwen 2.5 Coder is the proven code-trained workhorse — fine-tuned on a code-heavy mix, ranks near the top of HumanEval / MBPP for 32B-class. Qwen 3 32B is the newer general-purpose model with a stronger base + reasoning posture but no dedicated code fine-tune.
The decision frame: for pure code generation (single-file completions, refactors, FIM), Qwen 2.5 Coder still wins on quality-per-token. For agentic coding loops that mix code with reasoning, planning, and tool-use, Qwen 3 32B's stronger general capabilities often dominate.
The verdict for coding workloadsPick → Qwen 3 32B
slight edge for Qwen 3 32B — wins 1 of 10 dimensions (0 losses, 9 ties). Verdict reasoning below — no percentage shown on purpose (why).
Qwen 3 32B is the better fit for coding on the dimensions we score, taking 1 of 10 rows. The weighted score (0% vs 5%) reflects use-case priorities: quality (35%) + context length (15%) + fit (15%) lead. Both models are worth running — this just tells you which one to reach for first.

Which model wins on which VRAM tier. Picks update based on which one fits comfortably + which one’s strengths are unlocked by the available headroom.
| VRAM tier | Pick | Why |
|---|---|---|
| 16 GB | → Qwen 2.5 Coder 32B Instruct | Coder uses VRAM more efficiently per useful coding output. |
| 24 GB | → Qwen 3 32B | Qwen 3 32B fits with headroom; the newer training + reasoning posture is the daily-driver win. |
| 32 GB+ | → Qwen 3 32B | Plus you can load Coder as a sidecar for inline-completion workloads where its specialized training still wins. |
Is Qwen 3 32B a better daily-driver coding model than Qwen 2.5 Coder 32B?
Not for pure code-completion workloads — Qwen 2.5 Coder's code-specialized training still leads on direct generation. For agentic coding (Cline / Aider / Cursor loops), Qwen 3 32B's stronger reasoning posture often wins on multi-step tasks. Run both and A/B on your actual workflow.
Which one for inline autocomplete in VSCode / Continue.dev?
Qwen 2.5 Coder. Inline autocomplete is exactly the workload it was specialized for — fill-in-the-middle generation with low latency. The general-purpose Qwen 3 32B spends more tokens 'thinking' before producing code, which adds perceptible lag on every keystroke.
Can I run both simultaneously?
On 32 GB+ — yes, via vLLM with both models loaded as separate endpoints. On 24 GB — only one at a time. The operator pattern is: Coder for the IDE inline-completion endpoint, Qwen 3 32B for the chat-with-codebase / planning endpoint, swap based on workflow.
What about Qwen 3 Coder when it ships?
The Qwen team has signaled a Qwen 3 Coder is in the pipeline. When it lands, it'll likely replace Qwen 2.5 Coder as the default. Until then, the choice is between code-specialized (older) and general (newer).
