Qwen3 Coder Flash vs GPT OSS 20B vs ERNIE 4.5 VL 424B A47B

GPT OSS 20B is the better all-round choice, scoring 61/100 against Qwen3 Coder Flash (51) and ERNIE 4.5 VL 424B A47B (44). It leads on price. Qwen3 Coder Flash wins on context window. 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.

GPT OSS 20B is cheaper at $0.07 input / $0.25 output per million tokens (median across 37 API providers). Qwen3 Coder Flash costs $0.30 input / $1.50 output per million tokens (official Alibaba API price); ERNIE 4.5 VL 424B A47B costs $0.42 input / $1.25 output per million tokens (median across 1 API provider). At a typical mix of three input tokens to one output token, that is $0.115 per million tokens for GPT OSS 20B versus $0.60 for Qwen3 Coder Flash (5.2× as much) and $0.627 for ERNIE 4.5 VL 424B A47B (5.5× as much).

There is no independent benchmark that covers all three models yet. Qwen3 Coder Flash has not been scored yet, GPT OSS 20B has an ECI of 137.8 and ERNIE 4.5 VL 424B A47B has not been scored yet.

There are no published SWE-bench Verified results for Qwen3 Coder Flash, GPT OSS 20B and ERNIE 4.5 VL 424B A47B yet, so there is no like-for-like coding score. Test both on a sample of your own tasks. Note that ERNIE 4.5 VL 424B A47B does not support tool calling, which most coding agents need.

Qwen3 Coder Flash has the largest context window at 1,000,000 tokens, against 131,072 for GPT OSS 20B and 123,000 for ERNIE 4.5 VL 424B A47B . Maximum output per response: Qwen3 Coder Flash up to 65,536, GPT OSS 20B up to 32,768, ERNIE 4.5 VL 424B A47B up to 16,000 tokens.

Qwen3 Coder Flash accepts text; GPT OSS 20B accepts text; ERNIE 4.5 VL 424B A47B accepts text and images. ERNIE 4.5 VL 424B A47B handles the widest range of inputs.

GPT OSS 20B and ERNIE 4.5 VL 424B A47B publishes its weights and can be self-hosted; Qwen3 Coder Flash is proprietary.

GPT OSS 20B is the newest, released Aug 5, 2025. Qwen3 Coder Flash came out Jul 28, 2025; ERNIE 4.5 VL 424B A47B came out Jun 30, 2025. Knowledge cutoff: Qwen3 Coder Flash Apr 2025, GPT OSS 20B Jun 2024, ERNIE 4.5 VL 424B A47B Mar 31, 2025.

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.
