DeepSeek vs GLM-5.2
DeepSeek (freemium, AI Score 8.7/10) vs GLM-5.2 (freemium, AI Score 8.5/10). Side-by-side pricing, features, pros and cons, and which to pick.
The verdict
Pick DeepSeek if…
- →you want our editor's pick for this category
- →your primary use case is developers who own their agent harness and can hold a stable prompt prefix, since the cache rate is what makes deepseek cheap, and whose work is text rather than screenshots or audio.
Pick GLM-5.2 if…
- →your primary use case is engineering teams building coding agents who need frontier-class capability under a license they fully control — self-hosted, fine-tuned, or air-gapped — rather than rented from a closed api.

Pros and cons
DeepSeek
Coding · freemium
Pros
- ✓V4-Flash lists $0.14/M input and $0.28/M output, roughly 36x and 107x under GPT-5.6 Sol's $5 and $30
- ✓Cache hits at $0.003/M make a repeated agent prefix nearly free, blending to about $0.06/M on an agent-shaped traffic mix
- ✓MIT-licensed 284B/13B-active weights on Hugging Face, so the same model can be self-hosted or fine-tuned
- ✓1M-token context on both V4-Pro and V4-Flash handles whole codebases without chunking
- ✓Native Responses API plus stated Codex adaptation lets agent harnesses point at it without a chat shim
Cons
- ×Text in, text out — no image, audio or video input, so screenshot-driven debugging is off the table
- ×V4-Flash is a public beta: no SLA, movable rate limits, and no published throughput figure (Artificial Analysis lists Speed as N/A)
- ×Verbose output — 210M tokens across nine evaluations against a 100M median, which eats into the cheap-token advantage
- ×China-hosted inference, and the Responses path parks conversation state on DeepSeek's servers, a compliance question before an engineering one
GLM-5.2
Coding · freemium
Pros
- ✓MIT license at 744B parameters — commercial use, fine-tuning and redistribution with no revocable API terms or MAU clause
- ✓1M-token context handles whole repositories and long agent histories in one pass
- ✓Tuned for long-horizon, multi-turn tool use rather than one-shot completion, which is the workload coding agents actually run
- ✓Self-hosting is a genuine option for teams with data-residency or air-gap requirements, not a theoretical one
- ✓Materially cheaper than closed frontier tiers like GPT-5.6 Sol at $5/$30 per million tokens
Cons
- ×744B parameters means serious multi-GPU hardware to self-host, so most teams end up on the hosted API anyway — back on someone else's terms
- ×The launch claim of beating GPT-5.5 on long-horizon coding was vendor- and press-reported and still has no independent replication; GPT-5.6 Sol shipped in July and moved the comparison point
- ×The cheap-frontier field caught up fast — Qwen 3.8 Max at $2/$6 and Kimi K3 at $3/$15 offer comparable context, so GLM-5.2's cost edge is no longer distinctive
- ×Hosted API and Coding Plan prices are not published in an easily comparable form, and some enterprises face data-residency or procurement blocks on a China-based provider
