Windsurf vs MiniMax M3
Windsurf (freemium, AI Score 7.2/10) vs MiniMax M3 (freemium, AI Score 8.2/10). Side-by-side pricing, features, pros and cons, and which to pick.
The verdict
Pick Windsurf if…
- →your primary use case is developers already productive in windsurf's cascade workflow who have no urgent reason to migrate, and teams evaluating cognition's stack who want an editor-side agent sitting alongside devin's cloud agents.
Pick MiniMax M3 if…
- →overall capability matters more than price (AI Score 8.2 vs 7.2)
- →your primary use case is backend and agent developers running high-token coding workloads who need frontier-adjacent output at open-weights prices, plus teams that must self-host the model to keep source code on their own infrastructure.
Side-by-side specs
| Spec | Windsurf | MiniMax M3 |
|---|---|---|
| Category | Coding | Coding |
| Pricing model | freemium | freemium |
| Headline pricing | Free tier; paid plans from $20/mo (the Devin lineup now served at windsurf.com) — verify before buying | Freemium — open weights + usage-based API ($0.30/$1.20 per M at launch; check site for current) |
| Free tier | Yes, but it is credit-metered and is Devin's free tier, not the unlimited-basic-completions-forever tier this entry once described. That tier no longer exists. Confirm current allowances on the live pricing page before relying on it. | A free API tier for evaluation was available at launch, plus free self-hosting via the open weights. Check platform.minimax.io for current limits. |

Pros and cons
Windsurf
Coding · freemium
Pros
- ✓Cascade remains one of the better-designed agent loops: it plans, edits across files, runs commands, reads output and iterates without needing constant re-prompting
- ✓Repo-wide indexing means the agent locates the relevant files itself instead of making you paste context
- ✓Mixes cheap in-house SWE-series models for routine edits with frontier models for hard problems, so agent runs are not uniformly expensive
- ✓Enterprise self-hosted and air-gapped deployment with zero data retention, which Cursor does not offer at any tier
- ✓Full VS Code fork with terminal execution and file-write access, not a chat sidebar bolted onto an editor
Cons
- ×The founding team including CEO Varun Mohan left for Google DeepMind in July 2025 and Cognition bought what remained, so an independent product roadmap is not a safe assumption
- ×windsurf.com resolved to Cognition's Devin site when checked on 2026-08-10, meaning the plans a buyer actually encounters are Devin's and no Windsurf-branded price could be confirmed on any live page
- ×Cursor and Claude Code have caught up on multi-file agentic work, erasing the 2025 lead this entry's original 9.1 score was built on
- ×Pricing is credit-metered and hard to forecast for a team; the unlimited free tier that once made the product an easy recommendation is gone
MiniMax M3
Coding · freemium
Pros
- ✓Launch API pricing of $0.30/$1.20 per M tokens runs roughly an order of magnitude under GPT-5.6 Sol's $5/$30, and undercuts even OpenAI's cheap Luna tier
- ✓Open weights allow self-hosting, fine-tuning on proprietary code, and full inspection — no revocable API terms
- ✓1M-token context ingests an entire codebase or a long agent history without chunking
- ✓Served through OpenRouter and other third-party hosts, so evaluation does not require onboarding to MiniMax's platform
- ✓Tuned specifically for multi-step tool use rather than single-turn completion, which is what agent frameworks actually need
Cons
- ×The open-weights coding niche closed around it: GLM-5.2 ships 744B parameters under a permissive MIT license and Kimi K3 matches the 1M context, so nothing in M3's spec sheet is unique anymore
- ×MiniMax called the launch API rate promotional and has not committed to a durable published price — budget with the pricing page open rather than from a cached figure
- ×Text and image in, text out only. No voice mode, no computer use, no video generation; those live in separate MiniMax models you call separately
- ×Developer tooling and native IDE integration remain thinner than OpenAI's or Anthropic's, and Chinese-lab origin still stalls procurement at some enterprises
