RL fine-tuning is now live for @NVIDIAAI Nemotron 3 on Fireworks, starting with Nemotron 3 Super (LoRA). Train with GRPO and serve the model in one place.
We price by GPU-hour, not per token, so long multi-turn rollouts don't blow up your bill.

One platform for frontier model post-training and inference at production scale.

- In a joint Fireworks and @Faros_AI evaluation of 211 real engineering tasks, Claude Code + GLM-5.2 beat both Claude Code + Opus 4.8 and Codex + GPT-5.5: - Judge score: 0.568 vs. 0.521 and 0.466 - Time per task: 321s vs. 775s and 392s - Cost per task: $0.92 vs. $1.76 and $2.06With our partner @FireworksAI_HQ, we ran an evaluation to find out if open models have gotten strong enough to handle real software engineering work. Our result: Claude Code + GLM-5.2 matched Kimi on quality while running faster and cheaper. More details: faros.ai/blog/open-mode…
- Fireworks AI repostedCongrats! Open source GLM model is really a game changer! Extremely fast, cheap, and high quality!you may have heard that glm-5.2 at 280 token/s is cool, how about 318 and we still have room to go
- Open + closed models = better together. Our previous research with @harvey showed the benefits of combining a frontier closed model as an advisor agent with fine-tuned, open-source worker agents. Three benchmarks later, the result holds. In an even simpler set up, the open +
- Fireworks AI repostedThe underrated part of this announcement is that Fireworks has been quietly great behind the scenes helping us eval and serve these models Big kudos to the Fireworks team!Kimi K2.7 Code and GLM 5.2 are available in Devin Desktop and CLI Both perform strongly on FrontierCode Extended, our benchmark for real-world engineering tasks: GLM 5.2: 43.0% Kimi K2.7 Code: 39.5% Pro/Max/Teams users can try both models for free until July 5
- RT @Prof_OZ: This is worth understanding. Keeping up with AI is hard, I know. It move fast and knowledge compounds. Even I use AI to build…
- It's way easier to switch models than to switch harnesses, and like many of you we use @cursor_ai every day. Now you can try out the latest open-source frontier model without changing your workflow.You can now try GLM 5.2 in Cursor! Excited to see more useful open models, thank you to Fireworks for partnering here. Results from our evals ↓
- The hard part of reinforcement learning on a frontier model is the infrastructure that keeps training and inference numerically identical: zero KLD, end to end. We've solved this challenge, and are now offering it as a managed service, starting with GLM 5.2.
- GLM 5.2 is the open coding model everyone's been talking about. Now you can fine-tune it on Fireworks. SFT, DPO, and RL all supported. A leaderboard winner can still lose on your codebase. Training closes that gap. Take the strongest open coding base and turn it into a model
- Bring open models to where you're already working. FireConnect brings Fireworks' top models directly into Claude Code, Pi, OpenCode, and Codex. Watch our Head of AI Education @Prof_OZ show you how:How to run GLM-5.2 (Or Minimax or Qwen or Deepseek or Kimi) in Claude Code No JSON editing. No vim 😮💨 1. Install Claude Code npm install -g @Anthropic-ai/claude-code 2. Grab a Fireworks API key → fireworks.ai 3. Install FireConnect + drop in your key (one line):
00:00 - Fireworks AI repostedGLM-5.2 has been the most popular new model on Fireworks this past week. @ArtificialAnlys confirms why: #3 overall on GDPval-AA (1524 Elo), #1 open weights by 116 points. Interest is showing no signs of slowing. Try it on Fireworks today →GLM-5.2 leads open weights models and sits at #3 overall on GDPval-AA, a real-world agentic work benchmark GLM-5.2 from @Zai_org scores 1524 Elo on GDPval-AA, which measures performance on real-world, economically valuable knowledge work through long-horizon, multi-turn tasks.
- You don't need to be AI Dependent to build State of the Art software. @FactoryAI and Fireworks use GLM to build the most advanced agentic AI you can train and own today.
