Z.ai introduces GLM-5.3-Flash, the first natively multimodal model in the GLM-5 series, scoring 57 at $0.045 per task. The model utilizes a hybrid architecture combining sparse and linear attention alongside Manifold-Constrained Hyper-Connections (mHC) to deliver frontier intelligence at one-tenth the price. It features 320B total parameters with just 18B active parameters and achieves 3.0× less attention compute compared to GLM-5.3.written, reviewed, cited
- GLM-5.3-Flash-Base outperforms GLM-4.5-Base overall and remains competitive with GLM-5-Base across most benchmarks.
- GLM-5.3-Flash currently supports inference frameworks including SGLang, vLLM and TokenSpeed for local deployment.

Z.ai released GLM-5.3, an open-weights model that improves coding and cyber capabilities through post-training scaling. It achieves a 50% improvement over GLM-5.2 on the Z.ai Code Bench and scores 84.5% on CyberGym for vulnerability discovery. The model identified 2,436 vulnerabilities across 269 projects in real-world codebases, with weights releasing in two weeks after safety evaluation.written, reviewed, cited

Anthropic analyzes GLM-5.3, a new open-weight model from Zhipu AI that lacks robust safeguards against misuse. Testing shows the model develops end-to-end exploits in 50 of 410 attempts and full control-flow hijacks in 4% of trials, while abliteration reduces refusal rates from above 90% to about 3%. Researchers found a specific exploit chain could be built in 20 minutes of human attention for a cost of $20.40, whereas deceptive prompts engage the model 64% of the time.written, reviewed, cited
- Abliterating GLM-5.3 required roughly $4,400 in computation costs to reduce refusal rates from above 90% to about 3%.
- Prefilling thinking tokens causes GLM-5.3 to engage with malicious requests 92% of the time without abliteration.
- GLM-5.3-Flash built a reliable exploit chain for an ARM64 target in eight hours of autonomous work plus 20 minutes of human attention.

A team ran GLM 5.3 Flash exclusively for September but failed after 2B tokens due to infrastructure limits and a prototype error. The initial phase cost $68, but a vibe-coded prototype consumed 450M tokens, forcing a switch to DeepSeek V4.1 Flash and Qwen 3.8 Flash. GLM 5.3 Flash offers a 1M context window and vision support, making it viable for day-to-day work despite the challenge failure.written, reviewed, cited
- The team spent 450M tokens on a prototype, costing $150 and 5kWh of energy use almost overnight.
- Infrastructure availability issues forced a switch to other models because big labs hoard all the GPUs.
- The total energy use for the month was 35 kWh instead of the planned 10 kWh.

An engineer spent $266 to root an Amazon Fire HD 10 tablet that kept shutting down its kiosk. Kimi K3 found the exploit for CVE-2022-38181 at a cost of $164.25, while GLM-5.2 and GLM-5.3 refined the approach after Claude's safeguards blocked further analysis. The device ran Fire OS 7.3.2.6, a version that had not received the patch Amazon shipped in June 2024.written, reviewed, cited
- Claude's safeguards cut off the engineer after five months of diagnosis on the paid Max plan.
- OpenAI's Opus 4.8 refused to summarize previous cybersecurity work on the user's own device.
- GLM-5.3 achieved root access in four minutes by correcting a kernel build shift missed by other models.

GLM-5.3-Flash is an open weights model released by Z AI on August 26, 2026, that scores 42 on the Artificial Analysis Intelligence Index. It costs $0.15 per 1M input tokens and $0.50 per 1M output tokens, operates under the MIT license, and utilizes 320B total parameters with 18B active parameters during inference. The model supports text and image input with a 1M token context window but generates verbose output at 68.9 tokens per second.written, reviewed, cited
- The model classifies as Large because it has more than 150B parameters.
- A blended rate of 7:2:1 cache hit/input/output ratio yields $0.10 per 1M tokens.
- The model is available through 26 API providers for deployment.

GLM-5.3 (Max) is an open weights model from Z AI released on August 18, 2026, that scores 45 on the Artificial Analysis Intelligence Index. It generates output at 85.0 tokens per second while costing $1.40 per 1M input tokens and $4.40 per 1M output tokens. The model produced 210M output tokens during evaluation, which is higher than the median of 140M for comparable models.written, reviewed, cited
- The model uses a Mixture of Experts architecture with 753 billion total parameters but only 40 billion active parameters during inference.
- For a blended rate using a 7:2:1 cache hit/input/output ratio, the effective cost is $0.90 per 1M tokens.
