Best DiffusionGemma (Google) Alternatives in 2026

**Qwen-Image-2.1 went open-weight (weights 2026-09-14, blog 2026-09-20)** -- a unified text-to-image and editing model with a 7B visual-generation component, native transparent (RGBA) output, up to 10 reference images and mask-guided local edits -- but under a **research-only licence, not Apache**: commercial use needs a separate licence from Alibaba. Alibaba's open-weights + API family, and August 2026 was its biggest open-release month yet: **Qwen3.8-2.4T-A95B -- the Max-class flagship -- went open-weight on 2026-08-08** (custom Qwen3.8-Max licence), **Qwen3.8-27B** dense landed Apache 2.0 (8/05), and **Qwen3.8-Flash-Next** (8/24 weights, 8/26 blog) previews the Qwen4 architecture: 125B main + 51B n-gram embeddings with only 6B active, served as Qwen3.8-Flash at $0.15/$0.47 per 1M. Qwen 3.7 Max remains the GA API flagship ($2.50/$7.50)

**MiniMax M3.1 Flash (2026-10-19) is a 428B-total, 23B-active multimodal MoE with a 1M-token context at $0.15 input / $0.60 output per 1M tokens ($0.015 cached) on the MiniMax API, M Plan and MiniMax Code. Its weights are now on Hugging Face under the minimax-community licence, which needs a visible Built with MiniMax M3.1-Flash notice for commercial use and written approval above $20M yearly revenue.** **MiniMax-H3's weights are public on Hugging Face (repo 2026-07-28, updated 2026-08-13) under a community licence whose open-weight grant is limited to the US, EU, UK and South Korea**, and **MiniMax Music 3 (2026-08-07)** ships open weights for five-minute full-song generation with a prominent-attribution commercial clause. MiniMax's coding/agent flagship -- M3 (June 1 2026): 1M-token context, MSA sparse attention (>15x decoding speedup at long context), SWE-Bench Pro 59.0%, Terminal-Bench 66.0%. OPEN WEIGHTS LIVE on HuggingFace since June 12 (~428B total / ~23B active, native multimodal, minimax-community license)

The whole Trinity family moved to the Linux Foundation's OpenMDW-1.1 license on 2026-05-29 (no field-of-use restrictions). Arcee's own OpenAI-compatible API serves it at $0.25 / $0.80 per 1M input/output tokens

**DeepSeek-V4.1-Flash-1017 (2026-10-17) replaced V4.1-Flash on the web, app and API at unchanged prices** (the deepseek-flash model name now serves it; MIT weights on Hugging Face), with higher scores and shorter outputs, and DeepSeek opened its in-house **Search and Fetch APIs at $0.75 per 1,000 calls per endpoint** -- server-side Search/Fetch calls through DeepSeek Harness, Claude Code and Codex were free until 2026-10-31 16:00 UTC (00:00 Beijing time on 11/01) and are now past their free period. Earlier: **DeepSeek-V4.1-Flash shipped 2026-09-10**: a 552B MoE on a new Causal Encoder-Decoder architecture (8B active for input, 16B for output), natively multimodal, MIT-licensed on HF, and priced BELOW the V4-Flash it replaces -- $0.15/$0.60 off-peak, $0.30/$1.20 peak per 1M, with cache-hit input cut to $0.003/$0.006. V4-Flash and V4-Flash-Vision-Exp are retired (aliases route to V4.1-Flash). DeepSeek said V4-Pro would be phased out on 9/14, then **reversed that four days later** -- V4-Pro stays on the API at unchanged $0.66/$1.98 off-peak, $1.32/$3.96 peak until V4.1-Pro lands. V4.1-Flash's vendor benchmarks beat V4-Pro (DeepSWE 74.2, Terminal-Bench 2.1 90.6, GPQA 90.9)

**GLM 5.2 has a named production deployment at Perplexity: on 2026-09-21 Perplexity disclosed that Perplexity Computer sessions are served by GLM 5.2, post-trained by Perplexity on real user sessions** (21.2% relative cut in live tool-call failures). **GLM-5.3 and GLM-5.3-Flash released 2026-08-25** (weights on Hugging Face): 5.3 is a post-training-only upgrade of the 5.2 base that Z.ai calls 'the most capable open-weights model for coding' (Terminal Bench 2.1 88.2, DeepSWE 66.9, CyberGym 84.5) but moves from MIT to a custom licence; 5.3-Flash (320B/18B active, multimodal) stays MIT at $0.15/$0.50 per 1M.

Step 3.7 Flash (198B MoE, Apache 2.0) remains the smaller open model

**Mistral Large 4 ('Le Chonk') went open weight on 2026-10-29: the 1T-parameter multimodal MoE (49B active per token, 1M context) is on Hugging Face under the Mistral Ecosystem Open-Weight License, a modified MIT licence that allows commercial use except that Model-as-a-Service providers need a separate licence, and the API price dropped to $0.70 input / $0.07 cached / $2.10 output per 1M tokens, about half the preview rate. Earlier, on 2026-10-20: Voxtral 3, with Voxtral Mini Transcribe 3 at $0.0035 per minute, Voxtral Mini TTS 3 at $13 per 1M characters and a voice agent SDK.** **New 2026-10-15: Timestral, Mistral's first time-series forecasting family (5M, 28M, 123M and 209M parameters, weights on Hugging Face since 10/14 under a non-Apache licence), with the 209M model claimed first on GIFT-Eval, TIME and fev-bench and CPU inference in 10-140 ms.** **Mistral Large 4 ('le Chonk', ML4) entered public preview on 2026-10-06: a 1T-parameter natively multimodal MoE with roughly 50B active parameters, a 1M context window, callable as mistral-large-4 at a preview price of $1.36 / $0.14 cached / $4.18 per 1M tokens (batch at half price; cut to $0.70 / $0.07 / $2.10 on 10/29), with open weights then promised by the end of October, and vendor-claimed open-weight leads in cyber (Cybench 93%), coding (DeepSWE v1.1 61.7%) and agentic work (AutomationBench 59.9%).** **Mistral opened a Munich hub for Physics AI and Industrial AI on 2026-09-28**, confirming the May 2026 acquisition of Emmi AI (30+ physicists and engineers in computational fluid dynamics, structural mechanics and multi-physics simulation), naming BMW (crash simulation) and Siemens Energy as partners, and committing to **build one gigawatt of European compute capacity by 2030**. **Mistral now powers Firefox Smart Window (2026-09-16)** -- Mozilla's beta AI browsing assistant runs on Mistral models for France and North America, UK and Germany later this year, with zero data retention. **EUR 3B Series D at a EUR 21B+ post-money (9/08, Samsung-led)**; Cloudera partnership (9/10); Medium 3 retired 8/31 in favour of Medium 3.5.

Cohere's enterprise-multilingual Command A family. Command A+ (2026-05-20) is the Apache 2.0 successor: a 218B total / 25B active MoE covering 48 languages, with vision input, reasoning and translation in one model that runs on 2x H100 (or 1x B200), priced at $2.50 / $10 per 1M tokens on Cohere's API. The original 111B Command A (256K context, 23 languages) keeps CC-BY-NC 4.0 weights, so commercial self-hosting of that model requires a Cohere enterprise contract

UAE Technology Innovation Institute's open-weights family, now led by the hybrid Transformer and Mamba Falcon-H1 line (Falcon-H1R 7B for reasoning, Falcon-H1-Arabic, Falcon-H1-Tiny models from 90M parameters) alongside Falcon 3 and Falcon-E.
